Arthroscopic posterior cruciate ligament repair

This article presents a classic case of posterior cruciate ligament disruption, as an isolated entity, with avulsion of the cruciate from the tibia origin. The treatment is an arthroscopic technique for reimplantation of the posterior cruciate ligament, using the Instrument Maker staple for fixation to facilitate proper reduction of the posterior cruciate, and presents a follow-up with excellent range of motion and stability of the knee.     

Arthroscopic posterior cruciate ligament repair

Purpose: We present our technique of arthroscopic repair for femoral avulsion soft-tissue tears of the posterior cruciate ligament (PCL) and its results. Type of Study:Case series, retrospective review. Methods: We performed 13 arthroscopic repairs of the PCL and reviewed them retrospectively. Follow-up was available for 11 (85%) patients. Nonabsorbable monofilament sutures were placed through the loose fibers of the ligament and tied over a bone bridge. Patients were evaluated using magnetic resonance imaging, comparative stress views, and according to the scoring systems of Lysholm and Gillquist and the International Knee Documentation Committee (IKDC). Results: Mean follow-up was 51.4 months. IKDC scores revealed 4 (36.4%) patients with normal knee function, and 7 (63.6%) with nearly normal function. Average Lysholm and Gillquist score was 95.4 (90 to 100). All athletes returned to the same or a higher level of competition. Conclusions: Arthroscopic repair of the PCL in patients with a femoral avulsion is effective in reducing postoperative instability and improving functional outcome.Arthroscopy: The Journal of Arthroscopic and Related Surgery, Vol 18, No 7 (September), 2002: pp 695–702     

Gluteal compartment syndrome following abdominal aortic aneurysm repair: a case report

Compartment syndromes occur when the elevated tissue pressure within a confined limb's myofascial compartment exceeds capillary pressure, with subsequent neurovascular compromise. In order to reduce disability and the consequences of ensuring ischemia, it is essential for early recognition and intervention. This is more commonly recognized in the calf. We report an unusual case of gluteal compartment syndrome after abdominal aortic aneurysm (AAA) repair.     

臀筋膜间室综合征

目的:探讨臀筋膜间室综合征的发病机理,临床特点和手术治疗。方法:对4例臀筋膜室综合征病人进行减压治疗。结果:2例6小时内减压术后无后遗症,2例超过6小时减压遗留臀肌挛缩症、足下垂。结论:醉酒后臀部较长时间受压是GCS的主要病因,临床表现为臀部张力性包块、臀和髋关节疼痛并向小腿放射、踝反射和伸长肌肌力伸减弱,应尽早手术、彻底减压。     

Gluteal compartment syndrome

Gluteal compartment syndrome is uncommon and is often diagnosed late, resulting in muscle necrosis and sciatic nerve palsy. The mainstay of treatment is prompt diagnosis and early surgery. A high index of suspicion is essential, especially in the setting of major bleeding and excessive pain. Embolization and hyperbaric oxygen may be considered as adjuncts to surgery.     

Missed compartment syndrome after replacement of the anterior cruciate ligament following continuous epidural analgesia

Summary In this article we report a case of an early postoperative compartment syndrome of the anterior tibial compartment with complete sensomotoric palsy of the peroneal nerve after arthroscopic-assisted replacement of the anterior cruciate ligament (ACL) of the knee. The tourniquet pressure was 360 mm Hg and operation time was 1.75 h. After the operation the leg was bandaged to avoid swelling of the leg and as antithrombotic prophylaxis. Analgesic therapy was by continuous epidural bupivacaine infusion. Increasing pain of the lower leg was suppressed by additional analgesia. Due to persistent pain despite regular analgesia, the patient was sent to a main hospital on the 3rd postoperative day, where an extremely painful and swollen anterior tibial compartment with intracompartimental pressure of over 100 mm Hg was found. The compartment was released immediately. Despite the appearance of severe muscle damage, no extensive débridement was done. At the second examination, at 48 h, there was minimal perfusion of the muscles without contraction and islands of ischemic necrosis. Clinically, there was complete palsy of the dorsiflexors of the foot. The case shows the danger of a compartment syndrome when tourniquet of the limb, arthroscopy and a firm bandage are combined. Continuous epidural analgesia masks the classic symptoms of compartment syndrome.      

Gluteal compartment syndrome following elective unilateral internal iliac artery embolization before endovascular abdominal aortic aneurysm repair

During endovascular abdominal aortic aneurysm repair, aneurysmal involvement of the common or internal iliac arteries occasionally necessitates elective occlusion of one or both internal iliac arteries. Although elective internal iliac artery occlusion is often well tolerated, it can result in complications such as buttock claudication or rest pain, impotence, and colon ischemia. We report a case of gluteal compartment syndrome following elective unilateral internal iliac artery embolization prior to endovascular abdominal aortic aneurysm repair. On the first postoperative day, the patient developed sciatic nerve palsy, rhabdomyolysis, and renal failure, which promptly resolved after emergent operative exploration of his left buttock and debridement of all grossly necrotic muscle. This case emphasizes the point that, although elective internal iliac artery interruption is usually benign, it can have serious and unexpected complications that necessitate expeditious treatment for complete recovery.

Clinical outcome of arthroscopic repair of the posterior cruciate ligament

Twenty-one patients were evaluated with an average follow up of 30 month after arthroscopical reconstruction of the posterior cruciate ligament using the IKDC-Evaluation Document, Lysholm-Score, KT 1000 and X-ray. Complex ligament injuries and chronic instability of the knee were the indications for operative treatment. Semitendinosus – or patella ligament autografts were used. The Lysholm-Score significantly improved preoperatively to postoperatively (p < 0.01). The IKDC revealed 11 patients for group B, 7 patients for group C and 3 patients for group D. The KT1000 measurement showed a postoperative drawer of 3.6 mm compared with the nonoperated side. Thirteen of the 21 patients showed a posterior drawer of less than 3 mm. The lateral posterior stress view of the X-ray revealed a 4.1 mm ( ± 2.9 mm) side to side difference postoperatively in comparison to 9.5 mm ( ± 3.5 mm) preoperatively. Three patients possessed radiological signs of osteoarthritis grad I by Ahlb?ck. Our results recommend in patients with complex PCL-injuries as well as in cases of chronic posterior instability a complex reconstruction of the ligaments.     

Arthroscopic repair of the posterior cruciate ligament: Two techniques

Summary: Isolated posterior cruciate ligament injuries are rare and their treatment is controversial. These lesions have commonly been treated by open reduction and internal fixation using a posterior approach. However, this approach makes it difficult to explore other combined injuries of the knee joint. We report 2 cases of posterior cruciate ligament avulsion of the tibia that were arthroscopically reduced and fixed using 2 different methods, cannulated screws and tension band wire.Arthroscopy: The Journal of Arthroscopic and Related surgery, Vol 16, No 6 (September), 2000: pp 656–660

Long-term outcomes following single-bundle transtibial arthroscopic posterior cruciate ligament reconstruction

Purpose

Posterior cruciate ligament (PCL) injury has a reported incidence of 3–20 %. PCL reconstruction is aimed at reducing onset of premature articular degeneration and improving function. Numerous operative techniques have been described with varying degrees of result consistency.

Methods

We evaluated 15 patients treated for isolated primary posterior cruciate ligament injury with a mean follow-up of 4.1 years (range one to nine). Post-reconstruction clinical assessment included the Lysholm and Tegner knee scoring scale, international knee documentation committee (IKDC) ligament evaluation, and KT2000 arthrometer assessment.

Results

On the Lysholm knee score 11 patients (73 %) had excellent results, three patients (20 %) had good results and one patient (7 %) had a poor result. On the Tegner activity score the majority of patients scored 7–8 with a return to high level sports. At the final follow-up, the post-reconstruction IKDC score was normal or nearly normal (A and B) in 14 (93 %) patients, and abnormal (C) in one (7 %) patient. According to KT-2000 arthrometer measurements at final follow-up review, 11 patients (73 %) were rated as normal (A, 0–2 mm), and four patients (27 %) as nearly normal (B, 3–5 mm). These results were independent of age, mechanism of injury, time elapsed to surgical reconstruction, and length of follow-up.

Conclusions

Despite being a technically demanding procedure, the outcomes reported in this study show that single bundle transtibial arthroscopic PCL repair using four strands hamstring autograft provides satisfactory and consistent functional outcomes.     

Gluteal compartment syndrome after intramuscular gluteal injection

Complications after i.m. injection are rare. Only few cases need emergency operative treatment. This case report shows the exclusive situation of a gluteal compartment syndrome caused by a hematoma. Clinical findings showed signs of nerve compression with sciatic pain. Only immediate surgical treatment prevented persistent nerve or muscle tissue damage.     

Augmented repair as therapy of fresh injury of the posterior cruciate ligament

The discussion about the therapy of the posterior cruciate ligament persists. Conservative treatment, augmented repair, and reconstruction with autografts are discussed. From 1993 to 1997, 49 patients with posterior cruciate ligament rupture had repair Trevira ligament augmentation of 3 mm. There were 21 isolated and 28 combined ruptures. In 5 cases bony avulsions were refixed by screw or additional hook plate. Investigation of 36 patients, in 15 cases with isolated ligamentous ruptures was made. Osseous avulsion had good results in all cases. Isolated posterior cruciate ligament rupture showed good stability in 7 of 15 cases and instability of 2 + in 8 cases. The medial range Lysholm score was 76.8 (+/− 21.6), the OAK score showed 2 very good and 5 good results, 3 fair and 5 bad results. Using the IKDC score led to 3 very good and 4 good results, 2 fair and 6 bad results. Using subjective criteria, 10 patients described results as very good or good, 2 fair and 3 bad. Posterior cruciate ligament rupture with additional knee injury or fracture of the leg showed bad results in 60 % of cases, and good or fair results in only 40 %. We think augmented repair of fresh injury of the posterior cruciate ligament can be used as an alternative therapy to reconstruction with autograft.
