Core Tip

Core tip: The aim of this study was to compare the clinical effects of arthroscopy combined with unicondylar knee arthroplasty (UKA) and UKA alone for patients suffering from unicompartmental osteoarthritis during an average follow-up duration of 7.25 years. The hospital for special surgery score, knee society score, knee function score, femoral-tibial angle, and hip-knee-ankle angle increased significantly at the latest follow-up compared to pre-operation in both groups. The percentage of patients receiving blood transfusion (P = 0.003) and the total volume of blood transfusion (P = 0.001) were both significantly lower in the arthroscopy combined with UKA group than in the UKA alone group. Arthroscopic surgery has a unique advantage with regard to patient selection and a curative effect on cartilage degeneration in the lateral compartment.
