van Rensch PJH, et al. - Researchers conducted a cohort of 129 individuals to investigate whether the reported association at 2 years remains present at 7.5 years, and how clinical results at 7.5 years developed compared with baseline and 2-year follow-up, and whether individuals had additional adverse events. They selected individuals with a total system revision total knee arthroplasty (TKA). At 3 months, 1, 2, and 7.5 years, range of motion, Visual Analog Scale for pain and satisfaction, and clinical and functional Knee Society Score were collected preoperatively. The study found that all evidence except severe stiffness had a similar clinical outcome which was maintained up to 7.5-year follow-up. At longer follow-up, the severe stiffness group had worse results and deteriorated slightly. Outcome at 3 months appears predictive for long-term results. It was showed that further complications did not differ significantly for the different reasons for revision.
