Brief Summary
Modification(s)  		 This randomized controlled trial compares the effectiveness of platelet-rich plasma (PRP) injection combined with strengthening exercise versus conventional physiotherapy in knee osteoarthritis patients aged 40–70 years. The intervention duration is 8 weeks. Pain (primary outcome) will be measured using NPRS, while secondary outcomes include WOMAC, TUG test, 30-second Sit-to-Stand test, and knee range of motion using a goniometer. Follow-up will be conducted at 6 months to evaluate long-term effects.
