Supracondylar XXXX of the femur following prosthetic knee arthroplasty.

@entity1 @entity295 @entity174 @entity16 @entity158
Sixty-one supracondylar @entity174 above prosthetic knee replacements in 58 @entity1 were reviewed with a mean follow-up time of 3.7 years (range, 9 months to ten years). The mean interim between arthroplasty and @entity174 was 2.9 years (range, intraoperative to ten years). Twenty-seven cases demonstrated notching of the anterior femoral cortex. Seventeen @entity1 suffered from a severe @entity16 . Group A consisted of 30 @entity1 with 31 @entity174 treated by open reduction and internal fixation or revision arthroplasty. Follow-up study revealed 25 unions, three malunions, one nonunion, and two above-knee amputations for deep @entity295 . Four of 31 @entity1 had @entity158 levels or change in ambulatory status postoperatively. Group B consisted of 30 @entity174 in 28 @entity1 treated by casting alone or traction followed by cast bracing. Follow-up examination showed 17 unions, seven malunions, and six nonunions. Fifteen of the 30 @entity1 had @entity158 levels or change in ambulatory status after treatment. Casting produced significant decreases in motion in both groups. The results indicate that this @entity174 is associated with anterior notching of the femoral cortex and preexisting @entity16 . @entity1 with a supracondylar @entity174 following prosthetic knee arthroplasty are best managed by secure internal fixation and early motion.
