Fracture of the medial femoral condyle after unicompartmental knee arthroplasty.
Periprosthetic fracture is a relatively rare but well-recognized complication after knee joint arthroplasty. We experienced a case of medial femoral condylar fracture among 700 cases of unicompartmental knee arthroplasty (UKA). The patient was a 56-year-old woman who underwent minimally invasive UKA for medial osteoarthritis of the knee. A displaced medial femoral condylar fracture occurred 3 years after UKA. A closed reduction and percutaneous fixation using 3 cannulated cancellous screws was performed. Union of the fracture was achieved, and a full recovery of knee motion was gained after 3 months. The Knee Society knee and function scores were 87 and 80, respectively, at the 2-year follow-up. They were the same as the scores before the fracture took place, and there was no evidence of component loosening or ligament instability.
