Data relating to 369 cruciate-retaining unilateral TKRs performed at a single institution were collected prospectively. Fixed flexion was measured pre-operatively and at one week, six months, 18 months, three years and five years after surgery. <\/jats:p><jats:p> Using binary logistic regression, pre-operative FFD was a predictor of post-operative FFD &gt; 10\u00b0 at one week (p = 0.006) and six months (p = 0.003) following surgery.
