Investigators of this study found patients who underwent unicompartamental knee arthroplasty compared with patients who underwent total knee arthroplasty had higher Forgotten Joint Score, High Flexion Knee Score and satisfaction rate which demonstrated unicompartamental knee arthroplasty yielded better function and satisfaction and there was a need for less knee awareness.

Researchers identified 130 patients who underwent 136 unicompartamental knee arthroplasties (UKAs) and 810 patients who underwent 962 total knee arthroplasties (TKAs) for treatment of knee osteoarthritis. The minimum follow-up period was 2 years. Investigators performed propensity score matching for age, gender, BMI, operation side an WOMAC score. There were 100 UKAs matched with 100 TKAs, with each knee assessed with the WOMAC score, Forgotten Joint Score, High Flexion Knee Score and patient satisfaction at 2 years postoperatively.

Results showed WOMAC scores were not significantly different between patients who underwent UKA and those who underwent TKA at 2 years postoperatively. Investigators noted the Forgotten Joint Score and High Flexion Knee Score was significantly higher in patients who underwent UKA vs. those who underwent TKA. Of the patients who underwent UKA, 86% were satisfied compared with 71% of patients who underwent TKA. – by Monica Jaramillo
