Avulsion of the hamstring tendon from the ischial tuberosity is common in many sports, especially with younger athletes. The injury results from a sudden forceful flexion of the hip joint when the knee is extended and the hamstring muscles powerfully contracted. Early diagnosis and surgical repair with reattachment of avulsed muscles to the ischial tuberosity restore function and correct deformity. But, a delay in the diagnosis and treatment leads to a poor result functionally and clinically. Complication, such as heterotopic ossification and failure of the fixation, etc., were reported following a surgical procedure for this injury. However, sciatic nerve injury has not been reported in the literature. We report our experience of a sciatic nerve palsy after surgery that was performed three months after that the initial injury.

Weaver-Dunn's operation for acromioclavicular injury yields satisfactory results in most cases. Although clavicular prominence can recur, it is not frequently symtomatic, but it can cause serious impairment of shoulder function in young and active patients. The authors performed reconstruction of coracoclavicular ligament with an autogenous hamstring tendon graft in a 31 years old electrician with recurrence of clavicular prominence accompanied by pain and limitation of overhead activity. The hamstring tendon and two coracoclavicular sutures looped under the coracoid process were passed through holes in the clavicle and around the clavicle in overreduced position. Even though clavicular prominence recurred somewhat, the modified UCLA score by Rockwood improved to 17 from 11/20 at 2 years after operation and the patient had no restriction in working as an electrician. Symptomatic patient with recurrent clavicular prominence after Weaver-Dunn's operation can benefit from reconstruction of coracoclavicular ligament with a hamstring tendon.

Purpose: To evaluate the long term outcomes of the ACL reconstruction from the standpoint of osteoarthritis. Materials and Methods: We evaluated 31 patients who underwent ACL reconstruction from April 1986 to April 1999 and could be followed-up more than 7 years. Mean follow-up period was 10.1 years (7~22 years). In terms of the graft, 11 cases were treated with the ACL reconstruction using a autologous hamstring tendon graft, 20 cases were treated with using a autologous bone patellar tendon bone graft. For femoral tunnel, 11 cases were placed through transtibial tunnel, 20 cases were placed through anteromedial portal using mini-open arthrotomy. Functional and radiographic evaluation was performed. Results: Mean Lysholm score was $89.2{\pm}11.7$ points. Patients had KT-2000 side-to-side differences were $2.1{\pm}1.9\;mm$. IKDC ligament evaluation showed 38.7% type A, 48.3% type B, 6.5% type C and 6.5% type D. Femoral tunnel were placed at 11 or 1 o'clock position in transtibial technique and placed 10 to 10:30 or 2 to 2:30 o'clock position in technique using anteromedial portal. Radiographic analysis for degenerative arthritis revealed that in group using anteromedial tunnel, 50.0% were excellent, 25.0% were good. In group using transtibial tunnel 18.2% were excellent, 18.2% were good. Conclusion: More than 87.1% of cases, long term result of the ACL reconstruction showed good and excellent result in IKDC score. Especially, the group using tunnel through anteromedial portal showed good results for degenerative arthritis.
