Arthroscopic release of the glenohumeral joint in shoulder stiffness: a review of 26 cases. French Society for Arthroscopy.

The purpose of this multicenter retrospective study of arthroscopic release of the glenohumeral joint was to evaluate the technical feasibility, the results, and the potential correlations between results and cause of the stiffness. Twenty-six shoulders in 25 patients (19 women and six men) were re-evaluated 3 to 72 months (mean, 21 months) after arthroscopic release of the glenohumeral joint. Diagnoses were primary frozen shoulder in 13 cases, bipolar stiffness (rotator cuff tear plus capsular contraction) in 3 cases, and postinjury or postsurgery stiffness in 10 cases. Results were evaluated on passive range of motion, Constant's score, and subjective assessment. Anterior or anterior inferior capsular release was done at the anterior rim of the glenoid fossa. Posterior capsule release was not performed in this series. There were no intraoperative complications. Mean range of motion gains were 86 degrees for forward elevation, 72 degrees for abduction, 34 degrees for external rotation, and 6 spinal processes for internal rotation. Constant's range of motion score increased from 12.9 out of 40 to 32 out of 40 points. Thirteen patients were very satisfied, 5 satisfied, 5 improved, and 3 unchanged. Range of motion gains were independent from the cause of shoulder stiffness, but global results were better in the primary frozen shoulder group in terms of pain and strength. Arthroscopic release of the glenohumeral joint is feasible and safe. For primary frozen shoulders, in case of failure of the functional treatment, arthroscopic release is a less traumatic alternative to manipulation under general anesthesia. For bipolar stiffness, arthroscopy provides the opportunity for treating concomitant lesions. For postsurgical stiffness, arthroscopic release improves range of motion, but the shoulder often remains painful.

A multicenter study of 210 rotator cuff tears treated by arthroscopic acromioplasty.

We followed 210 cases of rotator cuff tears treated in four French centers by arthroscopic acromioplasty in 195 cases and by a tenotomy of the Long Head of Biceps (LHB) in 15 cases. All patients were evaluated by means of the Constant score (CS) and radiographic imaging. The mean age was 61 years and the mean follow-up period was 26.6 months (range, 12 to 93 months). The preoperative CS was 38.2 points; 41% were supraspinatus tears, 40.2% were supra and infraspinatus tears, 10.5% were three-tendon tears, and 8.1% were supraspinatus and subscapularis tears. The LHB was altered or disrupted in 77% of cases, dislocated or subluxated in 44% of cases. Acromioplasty was associated to tear debridement in 183 cases (88%) and to a tenotomy of the LHB in 38 cases (19%) of which 15 did not benefit from an associated acromioplasty. Global objective results shown by the corrected CS reached 79.7% and were satisfying in 73% of cases. Poor clinical factors were preoperative shoulder stiffness, postoperative painful crises, worker compensation, a preoperative history longer than 4 years, and young age. The poor anatomic factors were osteoarthritis, a lesion of the acromioclavicular joint or of the LHB tendon. An isolated supraspinatus tear will produce much better results than a triple-tendon tear. The persistence of an aggressive acromion was a prejudicial factor. The benefits of LHB tenotomy were evident and could be isolated in case of massive rotator tears. It seems that LHB tenotomy was particularly effective for massive tears of two or more tendons. Arthroscopic acromioplasty is an excellent indication for elderly patients without professional activity, functionally less demanding that a younger patient.

Hip arthroscopy in hereditary multiple exostoses: A new perspective of treatment.

The cases of 2 children (9 and 11 years old) with hereditary multiple exostoses disease are presented. The lesions were located primarily in the acetabular fossa of the left hip and caused pain and limitation of range of motion. Hip arthroscopy was performed to remove the exostoses without damaging the articular surfaces and the Y cartilage. After the procedure, the pain disappeared and normal range of motion was recovered for both children. Conventional surgery would have required hip dislocation to access these lesions with an increased risk of femoral head necrosis. These cases constitute a new and interesting application of hip arthroscopy.

[Post-traumatic hemarthrosis of the knee. Diagnostic steps and value of arthroscopy].

The authors report their experience of the arthroscopic diagnosis of acute traumatic hemarthrosis of the knee. They point out the value of testing stability under anaesthesia. A very important laxity, according to severe damage of peripheric structures and cruciate ligaments, need surgical repair. Otherwise, in all cases with minor instability, arthroscopy is very useful: some arthrotomies are so avoided, some associated lesions were diagnosed. Any way arthroscopy is reported to allow adequate treatment of traumatic hemarthrosis of the knee.
