Purpose : Repair of the posterior capsule tear at the time of the operation for the chronic postero-lateral or postero-medial rotary instability has not been reported. We describe the arthroscopic repair of the posterior capsule tear using the posterior trans-septal portal. Method : After conducting basic arthroscopic examination of the knee, postero-medial and postero-lateral portals are secure to make the posterior trans-septal portal, through which the postero-medial and postero-lateral capsule tears are repaired using the suture hook under the arthroscopic guidance. Conclusion : When arthroscopic reconstruction of PCL insufficiency or postero-lateral rotaty instability that accompanies postero-medial or postero-lateral capsular tears. rising the posterior traits-septal portal could ensure better visualization of the capsule and a subsequent more accurate repair of the capsule. Since it significantly lessened instability, it could contribute to an achievement of successful clinical results.

Purpose: This study is to analyze the prevalence of various intra-articular lesions in patients with traumatic recurrent anterior dislocation of shoulder over 40 years and suggest clinical implications for treatment. Materials and Methods: We retrospectively studied 16 cases that underwent surgical treatment for recurrent anterior dislocation of shoulder from January 2001 to May 2009. There were 9 males and 7 females, and the mean age was 52.7years. We carried out arthroscopic exam for all patients based on standard protocol, which included labrum, capular lesion, cuff, bony lesions. Results: All 16 cases showed Hill-Sachs lesion, 3 patients (19%) had bony Bankart lesion, 6 patients (38%) had labral tear. Capsular tear were found 15 patients (94%). Twelve (75%) had ruptured supraspinatus and 5 (31%) had subscapularis tear. Only one (6%) had SLAP lesion. Conclusion: There was relatively higher incidence of capsular and rotator cuff tears in patients over age 40 years. Preoperative planning to address these lesions is highly recommended.

A new method for arthroscopic resection of the inferior leaf for the horizontal tear in the anterior horn of the meniscus extending deep toward the capsule was developed. Resection of this tear is difficult-perhaps more so than any other meniscal tear. At arthroscopy, a small incision on the meniscotibial ligament of the anterior horn was made after the deep horizontal tear was carefully debrided. A retrograde punch was introduced through the incision and underneath the inferior leaf of the anterior meniscus. The inferior leaf of the anterior horn was resected by the punch without difficulty. This simple technique minimizes the risk of superior leaf injury and can be used for a horizontal tear in the anterior horn as well as the mid horn with sweeping motion of the retrograde punch.

Ultrasonography (USG) is widely accepted diagnostic method for the rotator cuff tear. The availability, low cost, easy to access is main factors that favor USG as a primary diagnostic modality for various cuff disorders. We experienced a case of discrepancy between USG, MR arthrography (MRA) and arthroscopic examination. Seventy four year old female patient complained of right shoulder pain. USG depicted rotator cuff tear with the size of 1cm, and MRA demonstrated about 3cm sized tear. Complex massive tear with delamination of degenerated rotator cuff was identified in the arthroscopic examination. When we encounter a patient who has loss of rotator cuff power or severe symptom than findings of USG, MRA or repeat USG is warranted. We report a case of discrepancy between examination modalities with brief review of the literature.

The iliopsoas bursa lies between the iliopsoas tendon and the anterior hip joint capsule and is difficult to detect by ultrasonography in normal setting. However, some of them communicated with the hip joint and the iliopsoas bursitis can be detected as a reflection of intra-articular pathology. We report two cases of acetabular labral tear accompanied with the iliopsoas bursitis detected by ultrasonography.

Recurrence is the most common complication after shoulder instability surgery, and the main causes of the postoperative recurrence of instability are trauma, misdiagnosis, and technical errors. The risk factors of recurrence may be classified as patient related, anatomical or technical. Causes of failure should be thoroughly evaluated by meticulous history taking, physical examination, and imaging studies, and followed by proper treatment of pathologic lesions. Nonoperative treatment should be considered initially in cases of recurred instability after shoulder instability surgery, but if this fails, repeated recurrence is prevented by performing appropriate anatomical reconstruction of ruptured Bankart lesions, capsular laxities, glenoid deficiencies and humeral head bone defects.

Purpose: We examined patients to evaluate the clinical results of traumatic metacarpophalangeal(M-P) dislocations of the thumb, uncommon and irreducible. Materials and Methods: In 11 traumatic M-P dislocations of the thumb, the types of dislocations were 10 dorsal and 1 volar dislocations resulted from the impacted and hyperextended forces on thumb. Authors evaluated the possibility of closed reduction, the anatomical structures interfering with closed reduction, and the surgical approaches. Results: Eight cases were treated with open reduction through volar approach and two cases were treated with closed reduction. Joint fusion was done with a plate in a chronic case. Initial closed reduction was attempted in all cases, but succeeded in only 2 cases because the interposed ruptured volar plate, the flexor pollicis brevis tendon and ulnar sesamoid bone at the volar side of the M-Pjoint were the obstacles to reduce. The metacarpal head was caught in button-hole slit between theflexor pollicis brevis and the ruptured volar joint capsule in all cases. Conclusion: Similar with the M-P joint dislocations of other fingers, the dorsal complex M-P dislocations of the thumb due to hyper extension are unusual and can't easily be reduced by closed manipulation. It is necessary to pay attention to the ruptured volar plate, capsule, the subluxated portion ofthe sesamoid and flexor pollicis brevis as interfering structures.
