Arthroscopic Anatomical Acromioclavicular Joint Reconstruction using a Button Device and a Semitendinosus Graft

ObjectiveTo report a new technique for anatomical acromioclavicular (AC) joint reconstruction.MethodsIn order to minimize such complications, the authors describe a new anatomical and biological AC joint repair. This technique aims to provide greater stability by using two anatomically placed clavicular tunnels and a combined construct with a double endobutton cortical fixation for primary stabilization, and to be biologically advantageous by using an autologous semitendinosus (ST) tendon graft. Additionally, the coracoclavicular ligament reconstruction is complemented with an AC joint cerclage and capsular reinforcement, which will protect the biological construction in its initial stage of healing.ResultsThis technique provides adequate primary and secondary biomechanical stability by passing both a semitendinosus autogenous graft and a double endobutton device, through anatomically placed and small diameter clavicle holes, without the need for coracoid drilling. Our technique showed encouraging results regarding pain resolution, range of motion, and function. At final follow‐up we experienced excellent results with average pain score of 1.6, and average ROM of 159° of forward flexion, 160° of abduction, 68° of external rotation, and internal rotation level at T11. Postoperative function also showed great improvements with average ASES of 85 points, an average Constant Score of 87 and a Subjective Shoulder Value of 89 points. This technique also achieved perfectly acceptable radiographic results, with an average coracoclavicular distance increase of 0.8 mm. Regarding complications, our sample showed one case of AC join subluxation, two cases of internal saphenous nerve injury, and two partial graft tears at the suture‐button interface, with none of these requiring surgical revision.ConclusionThis technique is advantageous in treatment of acromioclavicular joint dislocation and can be performed in both the subacute and chronic setting.     

Inveterate dislocation fracture of the sternoclavicular joint

We present the case report of a 21-year-old man with a late diagnosis of retrosternal dislocation of the sternoclavicular joint with a fractured sternal end of the clavicle. The first symptom leading to the diagnosis was dysphagia associated with physical activity. The diagnosis was based on computed tomography examination. In the first place, the fragment of the medial clavicular end was fixed with two screws. During surgery the sternoclavicular joint was wrongly identified; this fact was revealed by the following radiographic examination. On revision surgery, the sternoclaviculr ligament was reconstructed using a semitendinosus tendon graft. The reconstructed ligament was augmented with two Orthocord sutures running between the clavicle and the first rib. At 2 years after surgery the functional outcome and sternoclavicular joint stability were excellent.     

Biomechanical analysis of reconstructions for sternoclavicular joint instability

BACKGROUND: A variety of reconstructive methods have been described for the treatment of sternoclavicular joint instability, yet none have been analyzed in the laboratory, to our knowledge. The purpose of the present study was to evaluate three different reconstruction techniques with use of a cadaveric model: (1) intramedullary ligament reconstruction, (2) subclavius tendon reconstruction, and (3) reconstruction with use of a semitendinosus graft placed in a figure-of-eight fashion through drill-holes in the clavicle and manubrium. METHODS: Thirty-six fresh cadaveric specimens were mounted supine on a materials testing machine in a custom testing fixture and were subjected to anterior and posterior subfailure translation to determine stiffness in the intact state after preloading. One of the three reconstruction methods was performed, and the specimens were subjected to anterior or posterior translation to failure. Changes in stiffness compared with the intact state were analyzed statistically. RESULTS: In the anterior direction, the stiffness of the semitendinosus figure-of-eight reconstruction was significantly greater than that of the intramedullary ligament reconstruction but was not significantly different from that of the subclavius tendon reconstruction. The peak load to failure (as defined by translation equal to the anteroposterior diameter of the medial head of the clavicle) was 230.3 +/- 146.1 N for the semitendinosus figure-of-eight reconstruction, 84.6 +/- 45.7 N for the intramedullary ligament reconstruction, and 75.6 +/- 19.0 N for the subclavius tendon reconstruction. In the posterior direction, the stiffness of the semitendinosus figure-of-eight reconstruction was significantly greater than those of both of the other reconstructions. The peak load to failure was 241.4 +/- 49.7 N for the semitendinosus figure-of-eight reconstruction, 85.0 +/- 22.8 N for the intramedullary ligament reconstruction, and 51.5 +/- 28.9 N for the subclavius tendon reconstruction. CONCLUSIONS: The figure-of-eight semitendinosus reconstruction for sternoclavicular joint instability has initial biomechanical properties that are superior to those of the intramedullary ligament reconstruction and subclavius tendon reconstruction techniques. Clinical Relevance: While it is difficult to extrapolate in vitro data to the clinical situation, the figure-of-eight semitendinosus technique has superior initial biomechanical properties and may produce improved clinical outcomes in the surgical treatment of sternoclavicular joint instability.     

Revision anterior cruciate ligament reconstruction with doubled semitendinosus and gracilis tendons and lateral extra-articular reconstruction

BACKGROUND: The outcome of revision anterior cruciate ligament reconstruction has only rarely been reported. The purpose of this study was to evaluate the results of revision anterior cruciate ligament surgery with use of an autogenous doubled semitendinosus and gracilis graft in association with an extra-articular procedure. METHODS: Between 1997 and 2003, thirty patients underwent a repeat reconstruction of a previously reconstructed torn anterior cruciate ligament with use of a doubled semitendinosus and gracilis graft combined with an extra-articular reconstruction. Primary reconstruction had been done with an autogenous patellar tendon graft in twenty-six patients and with a prosthetic ligament in four patients; the average time from the primary reconstruction to the revision was five years. Functional outcomes, graft survival, and radiographic outcomes were evaluated at a mean of five years. A graft was considered to have failed when a revision was done or when the side-to-side difference on KT-1000 arthrometer testing was >5 mm and/or the pivot-shift test grade was greater than a trace. RESULTS: One patient underwent another revision reconstruction because of graft failure at three years postoperatively. The mean International Knee Documentation Committee (IKDC) subjective knee score for the remaining twenty-nine patients was 84 +/- 12 points, and the mean Lysholm knee score was 90 +/- 10 points. The side-to-side difference as measured with the KT-1000 arthrometer with maximum manual force was <3 mm in twenty patients (of the twenty-eight who returned for follow-up), between 3 and 5 mm in six patients, and >5 mm in two patients. The result of the pivot shift examination was normal in fifteen patients, slightly positive in eleven patients, and positive in two patients. Twenty-five percent of the patients showed no radiographic signs of degenerative joint disease. CONCLUSIONS: Revision anterior cruciate ligament reconstruction with use of an autogenous doubled semitendinosus and gracilis graft combined with an extra-articular procedure provided satisfactory functional outcomes, with a failure rate of 10%.     

Editorial Commentary: How to Increase Hamstring Tendon Graft Size for Anterior Cruciate Ligament Reconstruction

The concept of a five-strand hamstring tendon autograft for anterior cruciate ligament reconstruction is not new. The concept of a five-strand hamstring tendon autograft was largely ignored until recent studies showed higher failure and revision rates for hamstring ACL reconstructions performed with graft diameters less than 8 mm. In the majority of patients in the United Arab Emirates, four-strand hamstring tendon autografts result in a graft diameter between 6.5-7.5 mm. As a result, since 2006, I have completely abandoned using four-strand hamstring tendon autografts in favor of five-and six-stranded hamstring tendon autografts for ACL reconstructions. The key to performing five-or six-strand hamstring tendon autografts lies in the ability to triple the semitendinosus tendon and in the case of six-strand hamstring tendon grafts, the gracilis tendon. Although, five-and six-strand hamstring tendon autografts can increase the diameter of hamstring tendon ACL grafts, the question of whether these grafts will reduce failure and revision rates remains unanswered.     

Arthroscopic Coracoclavicular Ligament Reconstruction Using Biologic and Suture Fixation

Presented in this report is a modified arthroscopic approach to acromioclavicular joint reconstruction via suture and allograft fixation. An arthroscopic approach is used to expose the base of the coracoid by use of electrocautery. After an open distal clavicle excision is performed, clavicular and coracoid tunnels are created under arthroscopic visualization as previously described by Wolf and Pennington. The myotendinous end of a semitendinosus allograft is sutured to a Spider plate (Kinetikos Medical, San Diego, CA). The tendinous end of the graft is prepared with a running baseball stitch. A Nitinol wire with a loop end (Arthrex, Naples, FL) is used to pass 2 free FiberTape sutures (Arthrex) and the leading sutures from the tendinous end of the graft through the clavicular and coracoid tunnels, exiting out the anterior portal. One of the FiberTape sutures is retrieved with a grasper and passed over the anterior aspect of the distal clavicle. The second FiberTape suture and the allograft are passed over the distal end of the resected clavicle. While the acromioclavicular joint is held reduced, the FiberTape sutures are tied to the plate and the allograft is tensioned medially until the plate is embedded against the superior surface of the clavicle. The tendinous end of the graft is secured to the superior surface of the clavicle with a Bio-tenodesis screw (Arthrex) medial to the clavicular tunnel.     

Acromioclavicular reconstruction using autogenous semitendinosus tendon graft: results of revision surgery in chronic cases

Revision surgery of acromioclavicular dislocation is challenging owing to the altered anatomic relationships and the lack of stabilizing structures. In this study, an autogenous semitendinosus tendon graft was used for revision acromioclavicular stabilization, aiming at anatomic coracoclavicular reconstruction, as these patients had previously undergone a Weaver-Dunn procedure, which failed. Twelve patients were followed up clinically and radiographically for a mean of 49.5 months. The primary diagnosis was acromioclavicular joint dislocation Rockwood type III in 6, type IV in 4, and type V in 2 cases. At follow-up, the mean Constant score averaged 76.4 points. Pain relief was statistically significant (P < .01). Radiologic coracoclavicular distance and posterior displacement of the lateral clavicle in the Rockwood type IV cases decreased significantly (P < .01). We conclude that with this new technique of autogenous semitendinosus tendon graft replicating the anatomic ligamentous properties, good to excellent results can be achieved in revision cases of acromioclavicular reconstruction.     

A novel technique for reconstruction of the medial patellofemoral ligament in skeletally immature patients

Habitual or recurrent dislocation of the patella in the skeletally immature patient is a particularly demanding problem since the etiology is frequently multifactorial. The surgical techniques successfully performed in adults with patellar instability may risk injury to an open growth plate if applied to children. We present a technique that preserves femoral and patellar insertion anatomy of medial patellofemoral ligament (MPFL) using a free semitendinosus autograft together with tenodesis to the adductor magnus tendon without damaging open physis on the patellar attachment of MPFL. A 3-cm long longitudinal skin incision is performed 10 mm distal to the tibial tuberosity on the anteromedial side. The semitendinosus tendon is harvested with the stripper. The semitendinosus tendon is placed on a preparation board and cleaned of muscle tissue. The usable part of the tendon should be at least 20 cm long and 4 mm wide. The two free ends of the graft are sutured with Krakow technique. A medial longitudinal incision 2 cm in length is made to expose the MPFL and to abrade the patellar attachment of vastus medialis obliquus. The first patellar tunnel is created with 4.5 mm drill at the mid aspect of the medial patella in the anteroposterior and proximal–distal direction. The drill hole is formed parallel to the articular surface of the center of the patella. The second tunnel is created with 3.2 mm drill and the entry point is localized at the center of the patella. These two tunnels intersect to form a single tunnel. The semitendinosus autograft is run through the bone tunnel in the patella. Double-stranded semitendinosus autograft is placed in the presynovial fatty plane between the second and the third layer of the medial retinaculum, and tenodesis to adductor magnus tendon is applied by a moderate medial force with the knee flexed at 30°. Aftercare includes immobilization of the joint limited to 30° flexion using an above-knee splint for 2 weeks. No recurrent dislocation was observed in three patients (4 knees) at a mean follow-up time of 17.7 months. Both range of motion and radiological finding were restored to normal limits.     

Acromioclavicular Joint Reconstruction Using Peroneus Brevis Tendon Allograft

We describe the use of a double-strand peroneus brevis allograft to reconstruct the coracoclavicular and acromioclavicular (AC) joint ligaments. Through sharp dissection, the distal clavicle, the AC joint, and the torn superior AC and coracoacromial ligaments are identified. The coracoid process and injured coracoclavicular ligaments are identified with blunt dissection. A 1-cm segment of the lateral clavicle is resected. Vertical and connecting horizontal tunnels are created (4.5 mm) in the lateral clavicle and in the medial acromion process. The 5.5- to 6.0-mm-diameter allograft is looped around the coracoid process, and both strands are passed through the vertical clavicle tunnel with a nitinol wire loop. One strand passes through the vertical clavicle tunnel, and the other strand passes through the horizontal tunnel, exiting through the lateral end. The allograft strand passed through the vertical clavicle tunnel is then passed inferiorly through the superior vertical acromion tunnel, and the strand passed completely through the horizontal clavicle tunnel is passed laterally through the medial horizontal acromion tunnel. After both strands exit inferiorly through the vertical acromion tunnel, they are tensioned and sutured with AC joint reduction. Soft tissue closure uses No. 0 and No. 2-0 absorbable sutures with No. 3-0 nylon sutures at the skin.     

Semitendinosus muscle fatty infiltration following tendon harvest in rabbits

The hamstring tendon autograft is one of the most commonly used graft choices in Anterior cruciate ligament (ACL) reconstruction. There are conflicting results regarding postoperative hamstring strength deficits in patients who have had a hamstring graft. The semitendinosus tendon has been shown to regenerate after harvesting for ACL autograft, suggesting that the muscle has the potential to regain normal function. However, no studies have been performed to define the microstructural changes that occur in the semitendinosus muscle after tendon resection. In this study, we hypothesized that fatty infiltration of the semitendinosus muscle after tendon harvest in New Zealand White rabbits increases postoperatively and remains constant or increases during the first year of repair. The semitendinosus tendon was unilaterally detached and harvested from 15 rabbits. Five rabbits were sacrificed at 3‐, 6‐, and 12‐month intervals, and the semitendinosus muscle‐tendon units were analyzed. The contralateral unoperated limb served as the control. The gross tendon and muscle dimensions and histologic percentage of fatty infiltration were measured. We found no significant difference in fatty infiltration at any time point between the control muscle and test specimens and that there was no progression of fatty infiltration over time. If these results hold true in humans, natural repair of the hamstring muscle following tendon harvest during ACL autograft reconstruction is not inhibited by fatty infiltration. © 2013 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Reconstruction of the medial patellofemoral ligament using a longitudinal patellar tunnel technique

Patellar instability is a common clinical problem affecting a young, active population. A large number of procedures have been described to treat patellar instability. We present the clinical results in a case series of 25 medial patellofemoral ligament reconstructions in 21 patients with up to 30 months follow-up (mean: 7.3). Reconstruction was performed using either the gracilis or semitendinosus tendon autograft. The Tegner activity score improved overall from 3 to 4.4 at follow-up and the mean follow-up Kujala score was 87 (range: 55–100). No patella redislocations were observed. Five patients (20%) required a manipulation under anaesthetic but subsequently regained a satisfactory range of motion. Medial patellofemoral reconstruction with both gracilis and semitendinosus tendon graft using a longitudinal tunnel technique provided good post-operative stability restoring the primary soft tissue restraint to pathological lateral patellar displacement with no complications of post-operative patellar fracture.     

Concomitant reconstruction of the medial collateral and posterior oblique ligaments for medial instability of the knee

We present the operative technique and clinical results of concomitant reconstruction of the medial collateral ligament (MCL) and the posterior oblique ligament for medial instability of the knee using autogenous semitendinosus tendon with preservation of the tibial attachment. The semitendinosus tendon graft between the screw on the medial epicondyle and the tibial attachment of the graft was overlapped by the MCL, while the graft between the screw and the insertion of the direct head of the semimembranosus tendon was overlapped by the central arm of the posterior oblique ligament. Assessment was by stress radiograph and the Lysholm knee scoring scale. After a mean follow-up of 52.6 months (25 to 92), the medial joint opening of the knee was within 2 mm in 22 of 24 patients. The mean Lysholm score was 91.9 (80 to 100). Concomitant reconstruction of the MCL and posterior oblique ligament using autogenous semitendinosus tendon provides a good solution to medial instability.     

Prediction of hamstring tendon autograft diameter and length for anterior cruciate ligament reconstruction

The purpose of this study was to determine whether common physical measurements in patients undergoing anterior cruciate ligament (ACL) reconstruction with autologous hamstring tendon could be used to predict autograft length and diameter. One hundred nineteen consecutive patients undergoing hamstring autograft ACL reconstruction had these preoperative measurements taken: age, height, weight, bilateral leg length, and bilateral thigh girth 5 and 10 cm proximal to the superior pole of the patella. Correlations between these measurements and graft length and diameter were evaluated. There was a strong correlation between leg length and hamstring autograft length (r = .73, P<.001). Weight (r = .51, P<.001) and leg length (r = .42, P<.001) had only moderate correlations with graft diameter. All other correlations were weak. Regression analysis demonstrated that leg length can be used to predict hamstring autograft tendon length to within 20 mm and that weight can be used to predict graft diameter to within 1.2 mm using regression equations. In conclusion, several simple measurements correlate with doubled semitendinosus and gracilis tendon autograft length and diameter. This new information may prove useful to surgeons who want hamstring autografts of a certain diameter or of a long length.     

Initial biomechanical properties of anterior cruciate ligament reconstruction autografts

To provide more information to consider when selecting a reconstruction technique, we did a side-by-side comparison of some of the initial biomechanical properties of currently accepted reconstruction methods. Our research hypotheses were that a quadrupled, woven semitendinosus and gracilis graft is as strong as any of the other commonly used graft materials and that quadrupling and weaving the hamstring graft may increase the stiffness of the overall construct Using lower extremity cadaveric specimens harvested from young donors, we fashioned seven each of seven types of graft: 9-mm, 10-mm, and 11-mm-wide patellar tendon graft (PTG); 10-mm-wide central quadriceps tendon graft; doubled semitendinosus graft; tripled semitendinosus graft; and quadrupled, woven semitendinosus and gracilis graft. Specimens were stripped of remaining soft tissue, and anterior cruciate ligament (ACL) constructs were created for biomechanical testing. The tibia was translated anteriorly on the femur, mimicking a pivot shift maneuver, andfailure strength, failure mechanism, and construct stiffness were recorded. No differences in mean strength were detected. The quadrupled, woven graft was significantly stiffer than the doubled semitendinosus graft and no less stiff than any of the PTG constructs. All grafts showed similar and adequate initial absolute strength to reconstruct the ACL. Quadrupling and weaving the semitendinosus and gracilis graft increases the stiffness of the reconstructed specimen to a level statistically similar to that of specimens reconstructed with a PTG.     

Coracoclavicular Ligament Reconstruction Using a Semitendinosus Graft for Failed Acromioclavicular Separation Surgery

Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We report on the results of a technique for salvaging failed modified Weaver-Dunn reconstructions using a semitendinosus graft through bone tunnels in the distal clavicle and coracoid to reconstruct the coracoclavicular ligament.

Muscle and tendon morphology after reconstruction of the anterior cruciate ligament with autologous semitendinosus-gracilis graft

BACKGROUND: The autologous semitendinosus-gracilis graft is the first choice of many orthopaedic surgeons when reconstructing the anterior cruciate ligament. The effect that graft harvest has on muscle and tendon morphology remains unclear. The purpose of this study was to describe these effects more completely. METHODS: Magnetic resonance images were acquired from eight patients before the anterior cruciate ligament reconstruction with semitendinosus-gracilis autograft and then again postoperatively after they had returned to sports. Muscle and tendon morphology was described by determining the volume and peak cross-sectional area of each structure on digitally reconstructed images. The effects that the procedure had on muscle and tendon length were evaluated separately and then together as a muscle-tendon complex. RESULTS: Anterior cruciate ligament reconstruction with semitendinosus-gracilis autograft resulted in a marked decrease in volume, cross-sectional area, and length of the semitendinosus and gracilis muscles. Tendon regeneration occurred in varying degrees in nearly all subjects. The morphology of the biceps femoris and semimembranosus muscles suggested that they had been compensating for the reduced semitendinosus and gracilis muscle function. Although semitendinosus and gracilis muscle retraction occurred following tendon stripping, nearly all of the subjects displayed evidence of at least partial tendon regeneration. CONCLUSIONS: Anterior cruciate ligament reconstruction with semitendinosus-gracilis autograft had a marked impact on semitendinosus and gracilis muscle morphology. However, this altered muscle morphology did not appear to have a clinically important impact on short-term outcomes. The biceps femoris and semimembranosus muscles appear to compensate for reduced semitendinosus and gracilis function. Tendon regeneration is observed in most people, but it is often incomplete at six months.     

Revision anterior cruciate ligament reconstruction using the regenerated semitendinosus tendon: Analysis of ultrastructure of the regenerated tendon

In this report, we present a case of a college skier who sustained a rerupture of the reconstructed anterior cruciate ligament (ACL) 8 months after surgery in which an autogenous semitendinosus tendon graft was used. At the revision surgery, the harvested semitendinosus tendon appeared to be regrown. Thus the regenerated tendon was reharvested, and in combination with the gracilis tendon, was used as a graft. The electron microscopic examination revealed a difference in fibril diameter between the regenerated tissue and the normal tendon. Although the regenerated semitendinosus tendon could be reharvested, the feasibility of its use for revision surgery is still to be determined.     

Editorial Commentary: Acute Repair of the Acromioclavicular Joint Capsule and Ligaments and Deltotrapezial Fascia Could Allow Biological Healing of High-Grade Acromioclavicular Separation—Coracoclavicular Ligament Graft Augmentation Could Be Indicated if Time to Surgery Is Greater Than 3 Weeks

Surgical management of chronic acromioclavicular joint (ACJ) dislocations is a matter of controversy. In the acute setting of high-grade acromioclavicular separation, if a surgical repair of the ACJ capsule and ligaments and deltotrapezial fascia could allow biological healing of the ligaments themselves, this could be enough to restore the functional biomechanics of the joint; unfortunately, this is not true for chronic cases. In the latter situation, a surgical technique using biological augmentation such as autograft or allograft should be preferred. Time is very important for this injury, and a chronic lesion should be considered when treatment is being performed 3 weeks after trauma. The graft should be passed around the base of the coracoid or through a tunnel at the base of the coracoid itself and then at the level of the clavicle as anatomically possible to reproduce the function of the native ligaments. However, some studies have shown that passing the graft at the base of the coracoid and wrapping it around the clavicle could also achieve satisfactory outcomes. An arthroscopic technique, when used in combination, could be great to treat the associated lesions, which have a reported percentage between 30% and 49%. Finally, to restore the biomechanics of the ACJ, however, reconstruction of the acromioclavicular superior and posterior capsules together with the deltotrapezial fascia seems to be very important.
