Cidex-induced synovitis.

Microscopic evidence of inflammation was observed in the synovium of rabbit knees that had been injected with 10 ppm of Cidex (2% glutaraldehyde). Initial changes were synovial hypertrophy, subsynovial edema, and vascular congestion. At concentrations of 100 ppm or greater, focal synovial necrosis, hemorrhage, and gross diffuse synovitis were observed.

Periprosthetic femoral fractures following total knee arthroplasty.

Supracondylar and distal femoral fractures involving total knee arthroplasties present a relatively new and challenging problem. The alignment of the total knee components prior to and subsequent to the fracture, as well as the patients' range of motion, symptoms, and level of function following their treatment, were investigated in 14 cases. Ten of the patients had nonoperative treatment.

Chondromalacia patella: a nonoperative treatment program.

One hundred consecutively selected patients with chondromalacia patella were examined arthroscopically. The severity of the disease process was graded on the basis of the arthroscopic examination. A well-controlled nonoperative treatment program was instituted, and the end results were then tabulated when a minimum two-year follow-up had been achieved.
