Knee arthroplasty provides not only pain relief but also an improvement in function and range of movement. Limited joint mobility (LJM), secondary to peri-articular connective tissues stiffness, is a common complication of diabetes mellitus. We therefore examined functional outcome post-total knee arthroplasty (TKA) in a cohort of subjects with and without diabetes mellitus. The effect of TKA on indices of knee function (fixed flexion, maximum flexion, total ROM and knee society score) was examined in 367 subjects with type 2 diabetes and 367 subjects without diabetes. The groups were matched for age, sex, BMI and functional movement at baseline. Participants were examined at baseline (pre-operatively), 1, 5 and 10 years post-TKA.Introduction
