Patients were randomized to a 6-week intervention consisting of patient education combined with isolated hip-focused exercise (n = 39), traditional knee-focused exercise (n = 37), or free physical activity (n = 36). The primary outcome was Anterior Knee Pain Scale (0-100) at 3 months. Secondary outcomes were visual analog scale for pain, Tampa Scale for Kinesiophobia, Knee Self-efficacy Scale, EuroQol, step-down, and isometric strength.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>There were no between-group differences in any primary or secondary outcomes at 3 months except for hip abduction strength and knee extension strength. Between-group differences at 3 months for Anterior Knee Pain Scale were as follows: knee versus control, 0.2 (95% CI, \u20135.5 to 6.0); hip versus control, 1.0 (95% CI, \u20134.6 to 6.6); and hip versus knee, 0.8 (95% CI, \u20134.8 to 6.4). The whole cohort of patients improved for all outcomes at 3 months except for knee extension strength.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
