Arthroscopic rotator cuff repair: 4- to 10-year results

Purpose: The purpose of this article is to report the 4- to 10-year results of arthroscopic repair of full- thickness rotator cuff tears. Type of Study: This is a retrospective study evaluating a series of arthroscopic rotator cuff repairs performed by a single surgeon from February 1990 to February 1996. Methods: Retrospective chart reviews and telephone interviews were performed to evaluate the results of arthroscopic repair of rotator cuff tears. Results were evaluated using a modified University of California, Los Angeles (UCLA), shoulder scoring system. Results: One-hundred five arthroscopic rotator cuff repairs were performed in 104 patients between February 1990 and February 1996. Of these, 95 patients (96 shoulders) were available for follow-up evaluation at the time of this review. The mean UCLA score of all shoulders involved was 32. Fifty-one patients showed excellent results; 39, good; 2, fair; and 4, poor according to the modified UCLA scoring system. In no case was any loss of motion noted as a result of the surgical intervention. Conclusions: This retrospective study is the largest series of arthroscopic rotator cuff repairs with the longest period of follow-up thus far reported. Of the patients available for follow-up evaluation, 94% of patients qualified as a good to excellent result according to the UCLA shoulder scoring system. This study shows that patients treated with this arthroscopic rotator cuff repair technique have maintained excellent clinical outcomes 4 to 10 years after surgery. Level of Evidence: Level IV.     

Arthroscopic versus mini-open salvage repair of the rotator cuff tear: outcome analysis at 2 to 6 years’ follow-up

Purpose: The purpose of this study was to compare the outcomes of arthroscopic repair of medium and large rotator cuff tears with the outcomes for mini-open repair of similar tears in which arthroscopic repair was technically unsuccessful. Type of Study: Retrospective case series. Methods: We evaluated 76 patients who were treated for full-thickness rotator cuff tears either by all-arthroscopic (42 patients) or mini-open salvage of technically unsuccessful arthroscopic repair (34 patients). Patients who had acromioclavicular arthritis, subscapularis tear, or instability were excluded. There were 39 men and 37 women, with a mean age of 56 years (range, 42 to 75 years). At a mean follow-up of 39 months (range, 24 to 64 months), the results of both groups were compared using the University of California Los Angeles and American Shoulder and Elbow Surgeons shoulder rating scales. Results: Shoulder scores improved in all ratings in both groups (P < .05). Overall, 66 patients showed excellent or good and 10 patients showed fair or poor scores by the University of California Los Angeles scale. Seventy-two patients satisfactorily returned to previous activity, and 4 showed unsatisfactory returns. The range of motion, strength, and patient satisfaction were improved postoperatively. No differences were seen in shoulder scores, pain, and activity return between the arthroscopic and mini-open salvage groups (P > .05). However, patients with larger tears showed lower shoulder scores and less predictable recovery of strength and function (P < .05). Postoperative pain was not different with respect to the size of the tear (P = .251). Conclusions: Arthroscopic repair of medium and large full-thickness rotator cuff tears had an equal outcome to technically unsuccessful arthroscopic repairs, which were salvaged by conversion to a mini-open repair technique. Surgical outcome depended on the size of the tear, rather than the method of repair.     

Arthroscopic subscapularis tendon repair: Technique and preliminary results

Purpose: Our objective was to evaluate the preliminary results of 25 consecutive arthroscopic subscapularis tendon repairs. Type of Study: Case series. Methods: All 25 shoulders had longer than 3 months follow-up, with an average of 10.7 months (range, 3 to 48 months). The average age was 60.7 years (range, 41 to 78 years). The average time from onset of symptoms to surgery was 18.9 months (range, 1 to 72 months). The shoulders were evaluated using a modified UCLA score, Napoleon test, lift-off test, radiographs, and magnetic resonance imaging (MRI). Indications for surgery included clinical and/or MRI evidence of a rotator cuff tear. An arthroscopic suture anchor technique devised by the senior author (S.S.B.) was used for repair. Results: UCLA scores increased from a preoperative average of 10.7 to a postoperative average of 30.5 (P <.0001). By UCLA criteria, excellent and good results were obtained in 92% of patients, with 1 fair and 1 poor result. Forward flexion increased from an average 96.3° preoperatively to an average 146.1° postoperatively (P =.0016). Eight of 9 patients with a positive Napoleon test had complete tears of the subscapularis. All 7 patients with a negative Napoleon test had a tear of the upper half only. The lift-off test could not be performed reliably due to pain or restricted motion in 19 of the 25 patients. Eight patients had isolated tears of the subscapularis. The remaining 17 patients had associated rotator cuff tears with an average total tear size of 5 × 8 cm. Ten patients had proximal migration of the humerus preoperatively. Eight of these 10 patients had durable reversal of proximal humeral migration following surgery. These 8 patients improved their overhead function from a preoperative “shoulder shrug” with attempted elevation of the arm to functional overhead use of the arm postoperatively. Conclusions: (1) The senior author has been able to consistently perform arthroscopic repair of torn subscapularis tendons, with good and excellent results, in 92% of patients. (2) The Napoleon test is useful in predicting not only the presence of a subscapularis tear, but also its general size. (3) Combined tears of the subscapularis, supraspinatus, and infraspinatus tendons are frequently associated with proximal humeral migration and loss of overhead function. Arthroscopic repair of these massive tears can produce durable reversal of proximal humeral migration and restoration of overhead function.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 18, No 5 (May-June), 2002: pp 454–463     

Arthroscopic vs mini-open rotator cuff repair. A quality of life impairment study

We compared the clinical and quality of life related outcome of rotator cuff repair performed using either a mini-open or an arthroscopic technique for rotator cuff tears of less than 3 cm. The records of 64 patients who underwent rotator cuff repair between September 2003 and September 2005 were evaluated. Thirty-two patients underwent a mini-open rotator cuff repair, and 32 patients underwent an arthroscopic rotator cuff repair. The mean follow-up period was 31 months in the mini-open group and 30.6 months in the arthroscopic group (P > 0.05). The UCLA rating system, range of motion examination and the self-administered SF-36 used for postoperative evaluation showed a statistically significant improvement from the preoperative to the final score for both groups (P < 0.05). No statistically significant difference in the total UCLA scores was found when comparing the two repair techniques (P > 0.05). This study suggests that there is no difference in terms of subjective and objective outcomes between the two surgical procedures studied if patients have rotator cuff tears of less than 3 cm.     

Outcome analysis of arthroscopic treatment of partial thickness rotator cuff tears

Background:

Partial thickness rotator cuff tears occupy an important position in the spectrum of rotator cuff disease. The development of a more comprehensive classification has been sought to address both the tear location and extent, which may influence clinical results. The purpose of this study is to classify partial thickness rotator cuff tears according to the arthroscopic findings and to evaluate the clinical outcomes after arthroscopic repair of partial thickness tears.

Materials and Methods:

One hundred and two patients had arthroscopic treatment of partial thickness rotator cuff tears. The inclusion criterion for the study was a partially torn supraspinatus tendon involving articular or bursal side, verified by direct arthroscopic visualization. Outcome analysis was exclusively applied to patients who underwent transtendon repair, using the shoulder index of American Shoulder and Elbow Society and the University of California Los Angeles (UCLA) rating system.

Results:

Partial thickness rotator cuff tears were divided into five groups according to arthroscopic findings. There was significant improvement after surgery in all parameters of clinical evaluation in the tears that warranted repair. Arthroscopic repair in situ (transtendon technique) may be the preferred option in unstable partial thickness tear.

Conclusion:

The proposed classification system may assist decision making in the treatment of partial thickness rotator cuff tears.     

Arthroscopic repair of full-thickness tears of the rotator cuff: 2- to 14-year follow-up

Purpose: This study was performed to evaluate 2 arthroscopic techniques for rotator cuff repair used by 1 surgeon for more than 12 years. The main objective of this study was to test the reliability of these arthroscopic repair techniques not only using clinical assessment during the follow-up, but through observation of the healing process of the tendons during the arthroscopic removal of the staples in our first group of patients. Type of Study: This study was a before/after trial. Methods: We present the results of arthroscopic repair of full-thickness rotator cuff tears in 100 patients. In group I, 35 patients had staple fixation, and in group II, 65 patients had side-to-side suture and anchor repair. Follow-up ranged from 2 to 14 years. All shoulders were evaluated using the UCLA rating scale. Shoulders repaired with staples (group I) were evaluated arthroscopically at staple removal. Arthroscopic subacromial decompression was performed in 26 of the 35 patients in group I and in 65 of the 65 patients in group II; 58 patients in group II had concomitant resection of distal clavicle. Results: In group I, 22 patients (63%) had excellent results (UCLA scores, 34-35), 7 (20%) had good results (UCLA scores, 28-33), 4 (11%) had fair results (UCLA scores, 21-27), and 2 (6%) of the patients had poor results (UCLA scores, 0-20). In group II, 47 patients (72%) had excellent results (UCLA scores, 34-35), 12 (19%) had good results (UCLA scores, 28-33), 2 (3%) had fair results (UCLA scores, 21-27), and 4 (6%) of the patients had poor results (UCLA scores, 0-20). Conclusions: Patients with well-healed rotator cuff tendons had satisfactory postoperative results and better overall functional results. The arthroscopic techniques for rotator cuff repair achieve results comparable to the results of traditional open repair. However, these technically demanding arthroscopic procedures require advanced arthroscopic skills and have a steep learning curve.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 18, No 2 (February), 2002: pp 136–144     

Arthroscopic repair of massive rotator cuff tears: A prospective cohort with 2- to 4-year follow-up

Purpose: The goal of this study is to report on the complete arthroscopic repair of massive rotator cuff tears. Type of Study: Prospective cohort study. Methods: Between 1997 and 1999, 37 patients underwent complete arthroscopic repair of massive rotator cuff tears. The preoperative and postoperative outcomes of these 37 patients were analyzed using the constant score, American Shoulder and Elbow Society (ASES) index, visual analog pain scale (VAS), a single question of percent function compared with the opposite unaffected extremity, and a single question reflecting satisfaction (Would you undergo the surgery and the postoperative rehabilitation to achieve the result you have today?). The null hypothesis that was tested was that there was no difference between the preoperative and postoperative outcomes. The 37 patients were divided, by cohort design, into 2 groups; massive anterosuperior (AS; subscapularis, supraspinatus, and infraspinatus with or without the teres minor) and massive posterosuperior (PS; supraspinatus and infraspinatus, with or without the teres minor) tears. Additionally, the null hypothesis that there was no difference between outcomes for massive AS and massive PS subgroups was tested. Results: There was no statistically significant difference between either subset of massive rotator cuff tears with respect to preoperative and postoperative outcomes. The null hypothesis was supported for between groups. All but 2 patients said that they would undergo surgery again to achieve the postoperative state. Conclusions: The arthroscopic repair of massive rotator cuff tears is effective for decreasing pain and improving the functional status of the shoulder for most patients. Complete coverage was achieved in 78% of the patients at the time of surgery. A subset of patients who did not have complete coverage or coverage at a second setting showed similar outcomes as those with full coverage. The patient satisfaction rate was 95%.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 19, No 4 (April), 2003: pp 380–390     

Combined subcoracoid and subacromial impingement in association with anterosuperior rotator cuff tears: an arthroscopic approach

Purpose: The purpose of this study was to evaluate the surgical outcome of patients with combined subcoracoid and subacromial impingement with associated rotator cuff tears. Type of Study: Case series. Methods: Eight patients with a mean age of 63.6 (± 8.9) years were reviewed. All patients had combined subscapularis, supraspinatus, and infraspinatus tears of the rotator cuff with associated subacromial and subcoracoid impingement. All patients were treated with arthroscopic subacromial decompression, subcoracoid decompression, and rotator cuff repair. Results: At a mean follow-up of 8.8 months (range, 6–12 months), all patients were satisfied with the procedure. The mean University of California Los Angeles (UCLA) score increased from 11.0 ± 2.6 preoperatively to 30.9 ± 2.9 postoperatively (P < .00001). Preoperatively, all patients were in the poor category by UCLA criteria. Postoperatively, 2 patients had excellent results, 5 patients had good results, and 1 patient had a fair result. All patients had significant reduction in pain postoperatively, with 4 patients showing complete elimination of pain during all activities. No patient complained of pain anteriorly over the coracoid or had positive impingement signs postoperatively. Active forward elevation increased from a mean of 103.1° ± 46.5° preoperatively to a mean of 155° ± 18.5° (P < .02). Preoperatively, 4 patients had no active overhead function with positive Napoleon tests. Postoperatively, all showed improvement of the Napoleon test and regained active overhead function. Conclusions: Arthroscopic treatment of combined subcoracoid and subacromial impingement can lead to good results in this patient population. A high index of suspicion for these combined lesions, along with adequate surgical decompression and rotator cuff repair, is essential in providing pain relief and improved function.

Arthroscopic repair of anterosuperior (supraspinatus/subscapularis) rotator cuff tears

Purpose: The purpose of this study was to evaluate the outcome of patients who underwent arthroscopic repair of anterosuperior rotator cuff tears. The null hypothesis, that there was no difference between preoperative scores and postoperative scores, was tested statistically. Type of Study: A cohort study. Methods: The preoperative and postoperative status of patients with anterosuperior rotator cuff tears was analyzed using the Constant score, American Shoulder and Elbow Society Index (ASES Index), a visual analog pain scale (VAS), a single question of percent function compared with the opposite unaffected extremity, and a single question reflecting satisfaction, “would you undergo the surgery and the postoperative rehabilitation to achieve the result you have today.” There were also 2 groups compared: 1 that had a “tac” used for repair of the subscapularis tendon, and the other that used a “tie” technique for subscapularis repair. All supraspinatus tendon tears were complete and were repaired using a soft-tissue fixation device. Results: There was a statistically significant difference for all outcome measures except for the objective Constant score of the tie group, P = .58. Follow-up was 2 to 4 years. There were no differences based on sex or type of fixation device used for repair of the subscapularis tendon. There were no reruptures, clinically. Conclusions: The arthroscopic repair of anterosuperior rotator cuff tears provides reliable expectation for improvement in function, decreases in pain, decreases in clinical findings of biceps subluxation and inflammation, improvement in shoulder scores, and the improvement of clinical findings of subscapularis insufficiency.     

All-arthroscopic versus mini-open rotator cuff repair: A long-term retrospective outcome comparison

Purpose: The goal of the study was to compare the results of all-arthroscopic rotator cuff repair with those of our mini-open rotator cuff repair. Type of Study: Retrospective outcome study. Methods: Sixty-four shoulders (58 patients) were identified; 35 in the all-arthroscopic group and 29 in the mini-open group. Average follow-up for all patients was 44.6 months, with a minimum of 24 months. The all-arthroscopic group included 3 small tears (< 1 cm), 24 medium-size tears (1 to 3 cm), and 9 large tears (3 to 5 cm). The mini-open group included 2 small tears, 9 medium tears, and 18 large tears. All patients in both groups underwent arthroscopic assessment with arthroscopic subacromial decompression. None underwent formal acromioclavicular joint resection. Four of the all-arthroscopic and 11 of the mini-open patients underwent coplaning of the acromioclavicular joint. Anchors were the primary method of arthroscopic fixation, with an average of 1.5 anchors per case. Results: The average final follow-up UCLA score for the arthroscopic group was 32.6 and for the mini-open group was 31.4, and the average final follow-up ASES score for the arthroscopic group was 91.7 and for the mini-open group was 90.0. No patients in the arthroscopic group developed fibrous ankylosis, whereas 4 patients in the mini-open group developed the condition (14%). No anchor-related complications were noted. Shoulders in the all-arthroscopic group showed greater motion at 6 and 12 weeks postoperatively and slightly better motion at final review. However, final motion difference was not statistically significant. Overall, 4 patients (6.3%) demonstrated some tenderness in the acromioclavicular joint on palpation, but none had clinical symptoms requiring treatment. Conclusions: All-arthroscopic cuff repair provides comparable outcomes and complication rates to arthroscopic decompression with mini-open repair. The lower incidence of fibrous ankylosis favors the all-arthroscopic technique. A trend for better early motion was also noted in the all-arthroscopic group. Analysis of variance shows no measurable outcome difference between tear sizes.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 19, No 3 (March), 2003: pp 234–238

All-Arthroscopic Modified Rotator Interval Slide for Massive Anterosuperior Cuff Tears Using the Subdeltoid Space: Surgical Technique and Early Results

Background

Traditional intra-articular arthroscopic repair techniques for massive anterosuperior rotator cuff tears are technically demanding and necessitate sacrifice of the rotator interval to enable visualization. An interval slide allows mobilization through release of the medial aspect of the rotator interval, while leaving the lateral, bridging fibers intact.

Questions/Purposes

The purpose of this study was to report a novel, arthroscopic, open-equivalent technique using the subdeltoid space to address these tears along with early clinical results.

Methods

A retrospective review of prospectively collected data identified 11 consecutive arthroscopic massive anterosuperior rotator cuff repairs with a concomitant biceps tenodesis performed by the senior surgeon using a uniform technique. Outcome measures included range of motion, visual analog scale for pain, rotator cuff strength, American Shoulder and Elbow Surgeons (ASES) outcome scale, and Short Form-12 (SF-12).

Results

Average length of follow-up was 22.2 months (range 12.5–30.0 months). Visual analog scale (VAS) pain scores, ASES, and SF-12 all demonstrated significant improvement from pre-op to final follow-up from 6.2 to 0.9 (p?<?0.05), 27.4 to 82.8 (p?<?0.05), and 26.6 to 45.5 (p?<?0.05) respectively. Average forward flexion improved from 145° to 160° (p?<?0.05). Seven of the nine patients with a positive preoperative belly press had a negative test at final follow-up. Nine of the 10 patients with a positive lift off test demonstrated a negative test on final follow-up. Ninety-one percent reported they were satisfied with their outcome.

Conclusions

The described modified all-arthroscopic subdeltoid approach for anterosuperior cuff repairs enabled an open-equivalent interval slide technique that preserved the bridging lateral fibers of the rotator interval and demonstrated promising early-term clinical results.

     

Arthroscopic treatment of symptomatic shoulders with minimally displaced greater tuberosity fracture

Purpose: The purpose of this study is to describe arthroscopic findings and the results of arthroscopic treatment of patients with chronic shoulder pain caused by a minimally displaced fracture of the greater tuberosity. Type of Study: This is a retrospective case series in a consecutive sample of 23 patients with a minimally displaced or nondisplaced fracture of the greater tuberosity who underwent outcome analysis after arthroscopic treatment. Materials and Methods: Twenty-three patients with chronic shoulder pain beyond 6 months after fracture of the greater tuberosity underwent arthroscopic treatment and were retrospectively assessed after an average of 29 months (range, 22 to 40 months). There were 18 men and 5 women with the average age of 39 years (range, 24 to 61 years). Fourteen fractures were isolated and 9 were related to acute anterior instability episode. The average displacement of the fracture was 2.3 mm (range, 0 to 4 mm) as shown on anteroposterior view plain radiographs. Results: At the time of arthroscopy, all patients had partial-thickness rotator cuff tears on the articular surface. The cuff tears were located on the tuberosity fracture area and were an Ellman grade I to II in depth. After arthroscopic debridement or repair of the tear, depending on the condition of the tear itself, as well as subacromial decompression, the UCLA score results were good to excellent in 20 and fair in 3 patients. Nineteen of the patients had returned to the previous level of activities. However, the patients engaged in overhead sports activity had a lower level of return to activity (P =.034). Conclusions: A partial-thickness rotator cuff tear on the articular surface should be considered in patients with chronic shoulder pain after a minimally displaced fracture of the greater tuberosity. Arthroscopic debridement or repair is an appropriate procedure.Arthroscopy: The Journal of Arthroscopic and Related surgery, Vol 16, No 7 (October), 2000: pp 695–700

目的：探讨关节镜下锚钉改良植入,单排缝合修复老年肩袖撕裂方法及疗效。方法：回顾性分析2016年3月至2020年2月96例符合纳入标准的老年肩袖撕裂患者,其中男29例,女67例,年龄65~85（68.8±3.9）岁。采用关节镜下锚钉改良植入,单排缝合修复撕裂肩袖。手术前后采用美国加州大学洛杉矾分校（University of California Los Angeles,UCLA）评分,美国肩肘外科协会（American Shoulder and Elbow Surgeons,ASES）评分评估肩关节功能,采用视觉模拟评分（visual analogue scale,VAS）评估疼痛情况。其中32例术后1年患肩接受MRI检查。结果：所有病例完成关节镜下手术,随访时间11~42（21.4±7.5）个月,UCLA评分由术前的12.22±3.30提高至末次随访时的31.30±2.49（t=45.21,P<0.01）;ASES评分由术前的8.60±1.88提高至末次随访时的12.60±0.84（t=19.05,P<0.01）;VAS中位数由术前的5.00（2.00~8.00）分改善至末次随访的1.00（0.00~3.00）分（Z=-12.22,P<0.05）。术后1年32例接受MRI检查的患者中,1例显示修复肩袖再撕裂,但不影响正常生活,未再手术。未发现植入锚钉拔出病例。结论：关节镜下锚钉改良植入,单排缝合修复老年肩袖撕裂可取得较满意的疗效,能有效降低锚钉拔出并发症。     

The outcome and structural integrity of arthroscopic rotator cuff repair with use of the double-row suture anchor technique

BACKGROUND: The reported rate of failure after arthroscopic rotator cuff repair has varied widely. The influence of the repair technique on the failure rates and functional outcomes after open or arthroscopic rotator cuff repair remains controversial. The purpose of the present study was to evaluate the functional and anatomic results of arthroscopic rotator cuff repairs performed with the double-row suture anchor technique on the basis of computed tomography or magnetic resonance imaging arthrography in order to determine the postoperative integrity of the repairs. METHODS: A prospective series of 105 consecutive shoulders undergoing arthroscopic double-row rotator cuff repair of the supraspinatus or a combination of the supraspinatus and infraspinatus were evaluated at a minimum of two years after surgery. The evaluation included a routine history and physical examination as well as determination of the preoperative and postoperative strength, pain, range of motion, and Constant scores. All shoulders had a preoperative and postoperative computed tomography arthrogram (103 shoulders) or magnetic resonance imaging arthrogram (two shoulders). RESULTS: There were thirty-six small rotator cuff tears, forty-seven large isolated supraspinatus or combined supraspinatus and infraspinatus tendon tears, and twenty-two massive rotator cuff tears. The mean Constant score (and standard deviation) was 43.2+/-15.1 points (range, 8 to 83 points) preoperatively and 80.1+/-11.1 points (range, 46 to 100 points) postoperatively. Twelve of the 105 repairs failed. Intact rotator cuff repairs were associated with significantly increased strength and active range of motion. CONCLUSIONS: Arthroscopic repair of a rotator cuff tear with use of the double-row suture anchor technique results in a much lower rate of failure than has previously been reported in association with either open or arthroscopic repair methods. Patients with an intact rotator cuff repair have better pain relief than those with a failed repair. After repair, large and massive rotator cuff tears result in more postoperative weakness than small tears do.

Arthroscopic decompression for impingement syndrome secondary to an unstable os acromiale

Purpose: The purpose of this study was to examine cases of patients with impingement syndrome secondary to an unfused, unstable, os acromiale. Type of Study: Retrospective case series. Materials and Methods: Twelve consecutive patients (13 shoulders) presented with impingement symptoms in the presence of an os acromiale. The os acromiale, at the meso-acromion level, was seen on standard radiographs. The patients were all treated conservatively with rotator cuff strengthening, stretching, anti-inflammatory medications, and steroid injections. All patients underwent an impingement test with lidocaine, resulting in complete relief of their pain. After failure of the conservative management, the 12 patients (13 shoulders) underwent an extended arthroscopic subacromial decompression. The goal of the modified arthroscopic acromioplasty was resection of adequate bone to remove the mobile anterior acromial tip. In general, this consisted of more bony resection than the typical arthroscopic acromioplasty. Postoperatively, the patients began a rehabilitation program emphasizing early range of motion followed by isolated free-weight rotator cuff strengthening exercises. Five shoulders had a partial-thickness tear of the rotator cuff. Four involved less than 50% of the thickness of the rotator cuff. These 4 partial-thickness tears underwent arthroscopic rotator cuff debridement. One partial-thickness tear was greater than 50% and repair was performed with a mini-open deltoid-splitting technique. Results: Results were evaluated using UCLA shoulder scoring. Preoperatively, the score averaged 17. The 3-month postoperative score was 27, and at 6 and 12 months, averaged 28. The final follow-up score averaged 31. There were 11 satisfactory results with UCLA scores ≥28. Two unsatisfactory results showed UCLA scores in the fair category. Full strength of the anterior deltoid and rotator cuff muscles was achieved in all patients by 6 months postoperatively as evaluated by manual muscle testing. Twelve of the 13 shoulders were rated by the patients as having a satisfactory result. All of the patients rated their cosmetic results as acceptable. There was no evidence of postoperative deltoid detachment. No patient developed pain at the pseudarthrosis point. Conclusions: Given the previously reported poor results with attempts at fusion of an unstable os acromiale and open complete excision of meso-acromial fragments, the authors conclude that an extended arthroscopic subacromial decompression results in a reasonable outcome for patients with impingement syndromes secondary to an unstable os acromiale.Arthroscopy: The Journal of Arthroscopic and Related surgery, Vol 16, No 6 (September), 2000: pp 595–599     

Functional evaluation of patient after arthroscopic repair of rotator cuff tear

BackgroundRotator cuff tear is a common problem either after trauma or after degenerative tear in old age group. Arthroscopic repair is the current concept of rotator cuff repair. Here, we are trying to evaluate the functional outcome after arthroscopic repair of full thickness rotator cuff tear (single row) in Indian population.Materials and methodsTwenty five patients (14 males and 11 females) who underwent arthroscopic repair of full thickness rotator cuff tear at a single institution were included in the study. Postoperatively patient's shoulder was rated according to UCLA score, pain was graded according to the visual analog score. The range of motion was analysed and documented.ResultsThe mean age of the patients were 50.48 years. The preoperative VAS score mode was 7 and post operative VAS was 1 (p value <0.001). The UCLA grading was good in 80% (n = 20), fair in 12% (n = 3), excellent in 8% (n = 2) and poor results were seen in none of the patients.The mean UCLA improved from a score of 15.84 to 30.28 with a p value <0.001. Mean postoperative forward flexion was 161.6°, mean abduction was 147.6° and mean external rotation was 45.4°.ConclusionArthroscopic repair is a good procedure for full thickness rotator cuff tear with minimal complications. The newer double row repair claims to be biomechanically superior with faster healing rates without functional advantages, hence we used a single row repair considering the Indian population and the cost effectiveness of the surgery with good to excellent results.
