Fracture of the Medial Tibial Condyle in Unicompartmental Knee Arthroplasty: Report of 3 Cases

ABSTRACT

Unicompartmental knee arthroplasty(UKA) has become a popular method of treatment for medial osteoarthritis recently. UKA is now performed through minimally invasive surgery and it offers potential advantages including less postoperative pain, reduced blood loss, early rehabilitation, quicker recovery of range of motion and lower complication rate. Fracture of the medial tibial condyle is a relatively rare complication of UKA but it affects the prognosis of the implants and patient. We experienced 3 cases of medial tibial condylar fracture after UKA. Two cases were managed with open reduction and screw fixation, and one case was treated conservatively. All of the three patients were satisfied with the final outcome, so we report the cases of the medial tibial condylar fracture after UKA.
