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‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐‐
pain during activity, pain at rest,
pain during climbing stairs, pain during transfer activity, walking distance and range of motion all but walking distance and ROM are graded by HSS score (i.e. pain) |
