Functional Hip Strength Improvement in Knee Osteoarthritis Following Single-Dose PRP and a 6-Week Home Exercise Program

This single-group longitudinal study evaluated changes in hip stability isometric strength, knee muscle strength, and activity-related pain in women with knee osteoarthritis following a single-dose intra-articular platelet-rich plasma (PRP) injection and a 6-week home exercise program. Outcomes were assessed at baseline (5 days post-injection), week 6, and week 12. The intervention included strengthening exercises for knee and hip muscle groups performed three times per week and regular walking encouragement with weekly phone follow-up for adherence.
