Interventions Hylan G‐F 20
 (Synvisc) 3 weekly injections at baseline, Week 1 and Week 3,
 Exercise programme included a series of progressive, simple range of motion and resistance exercises for 6 wk. Home‐based regimen but patients came to hospital at baseline and weeks 1, 2, 3 and 6 to learn the exercises.
Outcomes Knee function evaluated by the Hospital for Special Surgery knee score criteria that is based on a total of 100 points with the score divided into 7 categories: pain, function, range of motion, muscle, strength, flexion deformity, instability, and subtractions. scores 85‐100 excellent, 84‐70 good, 60‐69 fair and less than 60 poor‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐
