Preoperative Frailty Correlates With Progression of Lateral Compartment Osteoarthritis After Medial Unicompartmental Knee Arthroplasty: A Mean 70-month Follow-up Study.
PURPOSE Lateral compartment osteoarthritis progression (LOP) is a major cause of mid to long-term failure after medial unicompartmental knee arthroplasty (mUKA). This study investigated whether preoperative frailty predicts LOP after mUKA over a mean 70-month follow-up. METHODS We retrospectively identified consecuti...
