Abstract

Introduction: Unicondylar Knee Arthroplasty (UKA) has been excellent surgical procedure to treat lateral and medial compartment osteoarthritis of knee joint. UKA has many advantages including short duration of surgery, minimal blood loss, early recovery and good functional outcome compared to Total Knee Arthroplasty (TKA). We aim to report the functional outcome of UKA among Indian population with midterm follow up. Materials and Methods: This was a retrospective study involving 94 patients who underwent UKA at single center from 2015 to 2016 for medial compartment osteoarthritis of knee joint. Demographic data including Gender, Body Mass Index (BMI) and Laterality, and Patient Reported Outcome Measures (PROMs) including Knee Injury Osteoarthritis Outcome Score (KOOS) and Forgotten Joint Score (FJS) were accessed during follow up of minimum 5 yrs. Results: The mean follow up duration was 6.9 ± 1.13 years. The mean age of patients was 67.2 ± 8.1 years and BMI was 26.4 ± 3.8 kg/m2. The preoperative KOOS Score improved from 39.2 ± 9.7 to 73.8 ±19.3 after surgery (p < 0.001) and Forgotten Joint Score at 5 years mean follow up was 75.70 ± 16.21. Survivorship of implant was 92% (95% CI) at 5 years follow up. Conclusions: UKA has good functional outcome at midterm follow up among Indian population and is an excellent surgery in management of medical compartment knee osteoarthritis. Further research can explore the long term outcomes and help in identifying factors that predict the success of UKA.
