Posterior capsular tightness with glenohumeral internal rotation deficit is usually considered to be an acquired condition of the throwing shoulder and is usually treated conservatively. However, because posterior capsular tightness is sometimes irreversible, we have performed arthroscopic capsular release for painful throwing shoulder with posterior capsular tightness. The true loss of internal rotation and posterior stiffness was confirmed by examination with the patient under anesthesia, and contracture of the posterior capsule and the posterior band of the inferior glenohumeral ligamant was observed arthroscopically. Because an extensive adhesion between the capsule and the fascia of the external rotators was noted, a capsular release was performed from 6 o'clock to 11 o'clock (in the right shoulder) to completely expose the muscle belly of the external rotators. Of the first 16 consecutive patients, 4 had no concomitant lesions and underwent posterior capsular release alone. With a minimum of 2 years' follow-up, it was ascertained that the throwing pain completely disappeared in 14 patients and improved in 2. In all, 11 patients returned to their preinjury performance level, and 5 returned to a lower level of function. In the 4 patients who had no concomitant lesions, throwing pain completely disappeared, and all were able to return to their preinjury performance level.

The aims of this retrospective study were to evaluate the results of inferior capsular shift operation which were approached anteriorly or posteriorly according to a main instability direction in contact sports population who had multidirectional shoulder instability. Fifty-three shoulders in 47 athletes who engaged in contact sports underwent an anterior or posterior inferior capsular shift procedure for the correction of multidirectional instability of the shoulder joint. The surgical approach was selected according to the predominant direction of the instability. Follow up was average of 42 months(24∼73 months). After anterior inferior capsular shift, anterior dislocation was recurred in three shoulders, posterior dislocation in one, and inferior dislocation in two shoulders. After posterior inferior capsular shift, one dislocation occurred anteriorly, one inferiorly and one posteriorly. The excessive tightening of capsule or improper diagnosis could be causative factors for the development of dislocation in the opposite direction to the preoperative major instability. Of six patients who could not return to their sports, five had bilateral repairs. Successful repair based on the criteria of the American shoulder and elbow association was achieved in 92% of anterior repairs, and 81 % of posterior repairs.

Background: We assessed the effectiveness of arthroscopic capsular release for the treatment of adhesive capsulitis. Further, we tried to ascertain the clinical benefits, if any, of pancapsular release over selective capsular release, where the two differ by performing or not performing a posterior capsular release, respectively. Methods: Thirty-five consecutive patients with either primary or secondary adhesive capsulitis who failed conservative treatment for more than 6 months were enrolled in the study. A total of 16 patients allocated in group 1 received a pancapsular release that comprises the release of the rotator interval, anteroinferior capsular, and the posterior capsular release, whereas 19 patients in group 2 received a selective capsular release that comprises only the release of the rotator interval release and anteroinferior capsular release. The clinical outcomes, visual analogue scale (VAS) score, Constant score, and range of motion, were assessed preoperative and postoperatively. Results: In both groups, the preoperative VAS score, Constant score, and ROM showed a significant improvement by the 6-month follow-up. We found that the immediate postoperative internal rotation was significantly higher in group 1 than group 2. Despite significant differences seen between the two groups at the initial postoperative period, there were no significant differences in Constant score, VAS score, and the ROM at all the subsequent follow-ups between the two groups. Conclusions: Arthroscopic capsular release for the treatment of adhesive capsulitis is very effective. However, pancapsular release did not show any advantage over selective capsular release in terms of overall clinical outcome.

Background: The study aimed to determine the type of capsular insertion and the extent of capsular elongation in anterior shoulder instability by quantitatively evaluating their computed tomography arthrographic (CTA) findings, and to investigate the correlation of these parameters with surgical outcomes. Methods: We retrospectively reviewed 71 patients who underwent CTA and arthroscopic capsulolabral reconstruction for anterior shoulder instability between April 2004 and August 2008. The control group comprised 72 patients diagnosed as isolated type II superior labrum anterior to posterior (SLAP) lesion during the period. Among the 143 patients, 71 were examined with follow-up CTA at an average 13.8 months after surgery. It was measured the capsular length and cross-sectional area at two distinct capsular regions: the 4 and 5 o'clock position of the capsule. Results: With regards to the incidence of the type of anterior capsular insertion, type I was more common in the control group, whereas type III more common than in the instability group. Anterior capsular length and cross-sectional area were significantly greater in the instability group than in the control group. Among patients of the instability group, the number of dislocations and the presence of anterior labroligamentous periosteal sleeve avulsion lesion were significantly associated with anterior capsular redundancy. Postoperatively, recurrence was found in 3 patients (4.2%) and their postoperative capsular length and cross-sectional area were greater than those of patients without recurrence. Conclusions: Capsular insertion type and capsular redundancy derived through CTA may serve as important parameters for the management of anterior shoulder instability.

The posterior and multidirectional instability of the shoulder is a complex problem in terms of diagnosis and treatment. Increased joint volume by redundant capsular ligament has been regarded as a major pathogenesis of the posterior and multidirectional instability. Distinct from multidirectional hyperlaxity, multidirectional instability has symptoms related with increased translations in more than one direction. Recent report that shoulder symptom originates from labral lesion which was created by excessive rim-loading of the humeral head on the posteroinferior glenoid labrum during repetitive subluxation helps us to understand the pathogenesis of such instability. Painful jerk and Kim tests indicate labral lesion in the multidirectionally loose shoulder, suggesting multidirectional instability. Also, painful jerk test is a prognostic sign of failure of nonoperative treatment. The labral lesion can be an incomplete tear or a concealed lesion which often has been underestimated. Operative treatment is indicated when nonoperative treatment has failed. Arthroscopic capsulolabroplasty is a reliable procedure, which not only provides capsular balance, but also restores the labral height.

Multidirectional instability of the shoulder joint is an unusual entity which is not yet well understood. Traditionally recommended treatment is non-operative, but recently arthroscopic treatment has been performed. This is a retrospective review of 20 patients who had multidirectional instability, who had been treated with arthroscopic capsular shift(7 cases), and arthroscopic treatment using Ho:YAG laser(l3 cases) at Department of Orthopaedic Surgery, Chungnam National University Hospital from July, 1988to February, 1997. Results of this study were as follows: 1. In five patients who were treated with arthroscopic anterior capsular shift only, all cases had redislocation of the shoulder joint. But there was no redislocation in two patients who were treated with arthroscopic anterior and posterior capsular shift. 2. ln three patients who were treated with laser-assisted capsular shift only, all cases had redislocation of the shoulder joint. But there was only one redislocation in ten patients treated with laser-assisted capsular shrinkage and capsular plication. Ho: Y AG laser has been found to be a safe and efficacious adjunct to many arthroscopic shoulder procedures. We had satisfactory results by combining a transglenoid capsular shift with laser-assisted capsular shrinkage. Arthroscopic laser-assisted capsular shrinkage and capsular plication is a one of recommendable treatment options in multidirectional instability of the shoulder joint.
