We investigated patients undergoing arthroscopic anterior cruciate ligament (ACL) reconstruction using otogeneous hamstring tendons with a cross-pin technique to compare a post-operative home-based rehabilitation programme with a clinic-based programme. ACL reconstruction was performed on 104 patients (103 male) by the same surgeon. The mean age of the patients was 31.5 years (range 18–43 years) and the mean time interval between injury and operation was 34.3 months. Patients were randomly allocated to either a home-based (n= 52) or clinic-based rehabilitation programme (n= 52). Mean follow-up was 31.1 months (range 12–66 months). Patients underwent a series of examinations before and after surgery in order to evaluate functional recovery of their injured knee. The results demonstrated that using otogeneous hamstring tendons for ACL reconstruction was safe and produced satisfactory results. The study also demonstrated that a home-based rehabilitation programme was as effective as a clinic-based programme.

We treated 26 hips (24 consecutive patients) with residual dysplasia by a technique of incomplete triple pelvic osteotomy. The mean age of the patients was 21.6 years.The mean values for the pre-operative centre-edge angle of Wiberg, the refined centre-edge angle, the acetabular angle of Sharp, the modified acetabular angle and femoral head lateralisation were 7.7°, -3.1°, 49.3°, 53.2° and 17.2 mm, respectively. After a mean follow-up of 3.3 years they were 27.0°, 13.0°, 38.9°, 44.3° and 15.9 mm, respectively (p < 0.05). The osteoarthritic grading changed adversely in one hip. The mean pre-operative and latest Harris hip scores were 74.9 and 93.0, respectively (p < 0.05).This technique provides a stable osteotomy with maintenance of the posterior column which allows early mobilisation and minimal internal fixation. The technique is not complex and requires minimal blood transfusion. The use of an image intensifier is not necessary and harvesting of a subcristal bone graft avoids post-operative complications at the donor site.
