The use of diagnostic and therapeutic arthroscopy has increased considerably in the past decade. Initially applied only to the knee joint, arthroscopy now has an established place in the treatment of shoulder, elbow and ankle disorders. Its use in the hand and the wrist is also expanding.
We report the results of arthroscopic removal of loose bodies and abnormal synovium from 18 knees with primary synovial chondromatosis. After a mean of three years, six months (range one to 10 years), 14 knees were either symptom-free or had only minor symptoms. Three of these had required two arthroscopic operations. Three patients were improved but not cured and there was one failure. The results were better than the published results of open operation for this condition. Three patterns of macroscopic appearances were noted: four knees had large lesions covered by normal synovium, 10 had small fragments of cartilage lying in or on the synovium and four had only free fragments of cartilage in the joint cavity but none in, on, or under, the synovium. These three appearances may represent three different disease processes.

A review of 107 footballers who suffered a spinal-cord injury between 1960 and 1985 has been undertaken. Since 1977, the number of such injuries in Rugby Union, Rugby League and Australian Rules has increased, from an average of about two injuries a year before 1977 to over eight injuries a year since then. Rugby Union is clearly the most dangerous game, particularly for schoolboys; all of the injuries in schoolboy games for this code have occurred since 1977. This study has shown that collision at scrum engagement, and not at scrum collapse, is the way in which the majority of scrum injuries are sustained. These injuries are largely preventable, and suggestions for rule changes are made. Half the injured players recovered to Frankel grades D or E. The financial entitlements of those injured were grossly inadequate; this warrants action. A national register for spinal-cord injuries from football should be established to monitor the effects of desirable rule changes in Rugby Union and Rugby League.
