[Purpose] To clarify the relationship between preoperative physical functions and Japanese Knee Osteoarthritis Measure (JKOM) scores at 6 months after total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA). [Participants and Methods] We examined 67 knees of 67 patients, who had undergone unilateral TKA or UKA, and were appropriate for assessment using the JKOM. To clarify the relationships among patient background factors, preoperative physical functions/gait/balance, and JKOM scores at 6 months after surgery, we performed multiple regression analysis, adopting the stepwise method. [Results] The patients’ JKOM scores at 6 months after surgery significantly varied, according to their preoperative TUG scores, levels of knee pain in rest on the operative side, and knee extensor strength on the non-operative side. [Conclusion] Preoperative TUG scores may be the most accurate predictor of patients’ QOL at 6 months after TKA or UKA.
