Arthroscopic reconstruction of the anterior cruciate ligament was introduced in our hospital in 1993. A study was done to compare the operative outcomes of this new arthroscopic technique and the old arthrotomy techniques for reconstruction of the anterior cruciate ligament. The study subjects were 27 patients who could directly be followed up.
Leeds-Keio artificial ligament and the patella ligament were used in combination in 10 patients (Group 1), and the Kennedy-LAD ligament and patella ligament in 5 patients (Group 2). The patella ligament was singly used under arthroscopy in 12 patients (Group 3).
The operative results and the location and postoperative changes in drill holes were compared among these three groups. The length pattern was recorded by measuring the distances between the attachment points of each reconstructed ligament on femoral and tibial bones in different knee flexion angles. The effect of ligament length patterns on drill hole changes was evaluated.

We report two patients suffered from separation of proximal tibial epiphysis as a result of jumping activity. The two patients were 16-year-old boys belonging to a tennis club. One was Salter-Harris type I separation, who was treated by closed reduction. The other one was type III, treated by open reduction and internal fixation.
Type of separation depends on epiphyseal maturation. Mechasism of this injury is imbalance of muscle power between quadriceps femoris and hamstring. Thirteen months after treatment, there is no evidence of complications and clinical course is proving successful.

In the past, the transplantation of stored tissue to fill defect areas has been undertaken, but recently there have been many advances in this method.
In orthopaedic surgery, cancellous bone grafting is frequently carried out, but there have been only a few rare attempts to perform osteochondral grafting in humans.
This is because, although, there are dozens of sources in the human body for cancellous bone grafts, the number of osteochondral tissue, is small.
This study was undertaken to examine the fate of rabbit osteochondral tissue, after storage by in vitro organ culture. The condition of the articular cartilage was evaluated by histological study at 1, 2, 3, 4, 8, 12, 16 and 18 weeks after storage.
The histological score fell moderately until 6 weeks, after which, it was almost unchanged until 18 weeks.
