Intervention group: Group A (Eccentric Exercise + Curcumin–Aloe Vera Gel): Curcumin–aloe vera gel (2 g) will be applied topically to the patellar tendon, followed by a supervised eccentric exercise. The program included wall sits, Spanish squats, box squats, and reverse lunges. All exercises will perform in three sets of 15 repetitions each, at a controlled tempo of 3 seconds eccentric and 1 second concentric. Sessions occurred 4 times per week for 8 weeks, with progressive loading applied biweekly according to pain-free tolerance (0–3/10 NPRS during exercise).

Control group: Participants will receive2 g of curcumin–aloe vera gel apply topically over the patellar tendon and delivered transdermally using therapeutic ultrasound. Ultrasound will be administered at a frequency of 1 MHz, intensity of 1.5 W/cm², in pulsed mode for 10 minutes using a circular application technique. Treatment will be administered 4 times per week for 8 weeks. No eccentric exercise or other therapeutic exercise will be included in this group to isolate the effect of ultrasound-mediated transdermal delivery of the gel. Adherence will be monitored through clinic attendance registers and self-reported gel application logs.
