Abstract

Various surgical methods including soft tissue procedures and bone procedures are commonly used to treat knee flexion and contracture deformity. However, several complications such as, neurovascular injury and skin necrosis were reported because of rapid correction. We aim to report good results from gradual correction using Ilizarov following supracondylar osteotomy in a 24-year-old man suffering from fused knee flexion and valgus deformity, a complication developed by septic arthritis.

Keywords: knee joint, flexion and valgus deformity, gradual correction

Figures and Tables

Figure 1

Preoperative photographs show flexion and valgus deformity of right knee.

Figure 2

Preoperative anteroposterior (A) and lateral (B) radiographs show a right fused knee joint with valgus and flexion deformity.

Figure 3

Intraoperative photograph shows correcting flexion and valgus deformity with Ilizarov following supracondylar osteotomy through lateral approach.

Figure 4

Immediate postoperative anteroposterior (A) and lateral (B) radiographs show a knee joint, corrected to preoperatively planed valgus and flexion angle with Ilizarov.

Figure 5

Second postoperative anteroposterior (A) and lateral (B) radiographs show a corrected knee joint which is fixated using pre-bended locking plate.

Figure 6

Radiographs taken at 3 months after second surgery show union of knee joint with corrected flexion and valgus deformity.

Figure 7

Long standing anteroposterior radiograph taken at 3 months after surgery shows leg length discrepancy of right lower leg.

Figure 8

Photographs taken at 3 years after surgery show an exposed plate with open wound.

Figure 9

Intaoperative photograph shows wound coverage using reverse anterolateral thigh island flap.
