UNLABELLED: Instability is a major cause of early revision of total knee arthroplasty (TKA), of which flexion instability is a major subset. We analyzed radiologically evident corrections, patient reported outcome and complications associated with revision TKA for flexion instability in a retrospective cohort of 37 patients with minimum one year follow up. Following revision surgery, there was a significant increase in mean posterior condylar offset ratio and a significant decrease in tibial slope while the level of joint line was not significantly altered. Patient reported version of knee society score showed significant improvement with surgery and 26 of 37 patient reported perceptible improvement on a 7-point Likert scale. LEVEL OF EVIDENCE: Level IV, Case series. See the Guidelines for Authors for a complete description of levels of evidence.
