Table 3 Reasons for reoperation for patients undergoing distal femoral resection knee arthroplasty, according to surgical indication
Indication for index surgery | Reoperation rate (%) | First reoperation | Second reoperation |
|---|---|---|---|
Osteosyntheses failure (n = 8) | 50% | 1: 19 days after index surgery, minor reoperation due to infection | |
2: 1071 days after index surgery, major reoperation with prothesis exchange due to loosening of prothesis | |||
3: 15 days after index surgery, major reoperation with prothesis removal due to infection | 23 days after index surgery and 8 days after first reoperation, amputation due to infection | ||
4: 889 days after index surgery, major reoperation with prosthesis removal due to infection (first stage of two-stage procedure) | 974 days after index operation, second stage of two-stage procedure | ||
Fracture (n = 2) | 0 | 0 | |
Periprosthetic fracture (n = 22) | 13.6% | 1: 29 days from index surgery, reoperation with total femur prothesis after fall and fracture of above-knee prosthesis and under-hip implant | 33 days from index surgery, minor reoperation due to cicatrice rupture |
2: 11 days from index surgery, prothesis exchange due to prothesis dislocation | |||
