Influence of autograft removal on rabbit patellar tendon length.

Twelve adult New Zealand white rabbits were randomly divided into two groups. In group 1, 30% of the central mass of the right patellar tendon was removed. In group 2, 60% was removed. The left knees served as controls. The animals were killed 1 year later. The patella-patellar tendon-tibial tuberosity units of all knees were studied using histological and morphometric analysis. In both groups, the tendons had lengthened. Lengthening average was 2.50 mm in group 1 and 8.17 mm in group 2. In both groups, histology revealed poor alignment of the collagen fibres and high cellularity, although the findings in group 1 were nearer the normal histological pattern. The results suggest that removal of significant portions of the patellar tendon leads to lengthening of the resulting tendon. In clinical practice, it seems prudent to pay attention to the dimensions of the patellar tendon when harvesting a graft.

Combined fracture of the talus: Arthroscopic treatment.

The purpose of this article is to report the treatment and short-term results of a combined fracture of the talus treated arthroscopically. A 29-year-old man sustained an anterolateral osteochondral grade III fracture of the talus dome associated with a coronal fracture of the body of the talus. This injury was reduced and fixed arthroscopically using cannulated screws. The patient returned to his daily style of living after 3 months time. One year later, the patient remains asymptomatic. Radiography showed neither signs of osteonecrosis nor osteoarthritis of the talus at the 1-year follow-up. Therefore, arthroscopic surgery could be an alternative treatment for this kind of talus fracture.

Osteochondritis dissecans: a historical review and its treatment with cannulated screws.

The etiology of osteochondritis dissecans and the results of treating the early stages with arthroscopic fixation using cannulated screws is discussed. Arthroscopic surgery was performed on 14 patients with osteochondritis dissecans, and the osteochondral fragment was fixed with one or two screws. A second arthroscopic procedure was necessary to assess the lesion and remove the screws. Ambulation without weight bearing is allowed during the first 2 months postoperatively. Full range of motion is encouraged. The results indicate that all patients returned to their previous sport 3-11 months postsurgery. The authors conclude that fixation with cannulated screws is the ideal method of treating osteochondritis dissecans when the osteochondral fragment is still in its bed.

Ring-shaped lateral meniscus.

The existence of abnormal-shaped menisci has been long recognized. The presence of discoid menisci in the human knee is considered to be a congenital malformation with a very low rate of incidence except in Asian populations. Since the publication of Watanabe's Atlas, three types of lateral meniscal abnormalities are generally accepted: the complete and incomplete discoid, as well as the Wrisberg-ligament type meniscus. The present case is the second description of a ring-shaped meniscus on the lateral side of the knee and we propose that this variant be included as a fourth variant in a future classification.
