Figures 1A-B. Conventional AP (A) and lateral (B) radiographs taken 6 years after extra-articular resection for an osteosarcoma of the distal femur in a 46-year-old female patient. The defect was reconstructed with an uncemented HA-coated MUTARS distal femoral replacement with a PEEK-OPTIMA locking mechanism. The postoperative course was uncomplicated and no further procedures were undertaken.

Mechanical Complications
Complications of soft tissue or instability (Henderson type 1) occurred in seven reconstructions (seven of 110 [6%], six distal femoral replacements, one proximal tibial replacement) after a median of ve months (range, 0 – 46 months). These complications included skin necrosis (n = 2 [two of 110, 2%]), exion contracture (n = 2 [two of 110, 2%]), and patellar dislocation (n = 1 [one of 110, 1%]).
One patient underwent surgery for extensor mechanism insu ciency (n = 1 [one of 110, 1%]). We could not identify factors associated with the occurrence of
