We present our technique for reconstruction of the posterior cruciate ligament (PCL) using the quadrupled hamstring tendons with EndoButton(Acufex Microsurgical, Mansfield, MA). This paper describes the surgical technique of the procedures and reports the preliminary results in 10 patients with a more than 12 months follow-up. There were 8 males and 2 females ranging in age from 17 to 37 years (average 25 years). The average time from injury to operation was 3 weeks (range; 2 weeks to 4 weeks). Of ten patients, 6 were classified as an isolated tear, 2 were associated with lateral collateral ligament tears. A torn meniscus was present in 2 cases. We used one-incision technique. The results of these PCL reconstructions with a minimum follow-up of 12 months are as follows. Patients were evaluated preand postoperatively using the Lysholm, and Hospital for Special Surgery Knee ligament rating scales. Average knee ligament evaluation scores were Lysholm preoperative 48, postoperative 87.6; and Hospital for Special Surgery preoperatively 33.5, postoperative 88.8. We chose the semitendinosus and gracilis tendons with EndoButton fixation for PCL reconstruction for specific reasons: (1) No injury to the extensor mechanism and (2) Easy passage of the graft through the tibial tunnel. (3) The problem about the screw and patellar bone-tendon-bone can be resolved. (4) It preserves intact meniscofemoral ligament, some intact fibers of PCL bundle. (5) When rupture of the PCL is associated with ACL tear, each ligament should be reconstructed. In such a case, we preserve patellar tendon for reconstruction of the ACL, The technique presented here is not applicable to all individuals requiring PCL reconstruction but does provide significant advantages to those patients for whom it is utilized. Although the clinical results are very promising at this length of follow up, long-term study is required to evaluate our PCL reconstruction procedure more precisely.

From 1993 to 1996, we have used a new modular shoulder prosthesis for the treatment of acute complex fracture of the proximal humerus. The purpose of this study is to evaluate function, pain relief, and patient satisfaction after moduiar hemiarthroplasty for proximal humerus fractures. The stucly included 12 patients (J2 shoulders) with an average age of 68.5 years (range, 60 to 84 years). According to the Neer classification system, there were 3 four-part fracture-dislocations, 5 four-part fractures, 3 three-part fractures, and #I head splitting fracture. 'fhe hemiarthroplasty was pert'ormed at an average of 4 days (range, 3 to 10 days) following injury. Deltopectoral approach was used in all patients, and the prostheses were implanted with cement in ten cases. Follow-up evaluation, at an average of 32 months post-surgery, included clinical and radio- graphic examination. Active forward elevation averaged 120 degrees; external rotation, 35 degrees; and internal rotation, to the first lumbar vertebra. All of patients, except two who had poor results, were graded as good or excellent according to UCLA shoulder rating scale. Complications consisted of one tuberosity dispiacement, one peri-operative death and one loosening of uncemented humeral prosthesis. We concluded that Modular hemiarthroplasty for acute complex fracture of the proximal humerus especially in severely osteoporotic elderly patients facilitated the restoration of humeral length, anatomic repositioning of tuberosities, and precise soft tissue balance, thereby allowing earliermotion to prevent the developement of painful shoulder stiffness.

Several immunosuppressive agents were used to prolong the survival of full-thickries skin homografts in albino rats. The grafts were squares in size of 2.0cm. The results were as follows. 1. The mean survival time of skin homografts in control group was 6.0 days. 2. Total body X-irradiation (500r) to the recipients 24 hours before grafting resulted in prolongation of survival of the grafts. (Mean, 12.5 days) 3. Administration of Imuran(azathioprine) to the recipients in a does of 5mg/kg/day for 7 days. before grafting resulted in prolongation of survival of the grafts. (Mean, 9. 6 days) 4. Spleneetomized homografted rats showed no prolongation of survival of the grafts. (Mean, 6.1days) 5. Administration of prednisolone to the recipients in a does of 2mg/kg/day for 7 days before grafting resulted in no prolongation of survival of the grafts. (Mean, 6.3 days) 6. Above results were discussed and compared with those of others.
