Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 45–55 with primary knee osteoarthritis grade II–III (Kellgren–Lawrence), BMI ≤35, current pain ≥4/10, and at least one active gastrocnemius trigger point.

Probably not a fit

Patients with advanced (grade IV) knee osteoarthritis, BMI >35, no gastrocnemius trigger points, or significant comorbidities may be unlikely to benefit from this intervention.

What this trial studies

This interventional trial compares gastrocnemius myofascial release plus conventional physical therapy to sham gastrocnemius myofascial release plus conventional physical therapy in females with knee osteoarthritis. Participants receive real or sham gastrocnemius MFR three times per week for four weeks while both groups undergo standard physical therapy. Outcomes measured include pain, physical function, foot posture, and knee disability assessed before and after the intervention. The single-center trial is conducted at the Faculty of Physical Therapy, Cairo University and enrolls women with radiographic grade II–III knee osteoarthritis, BMI ≤35, and baseline pain of at least 4/10.

Why it matters

Potential benefit: If successful, adding gastrocnemius myofascial release could offer a low-cost, noninvasive way to reduce pain and improve mobility for middle-aged women with knee osteoarthritis.

How similar studies have gone: Small trials and case series have suggested myofascial release can reduce pain and improve function in knee osteoarthritis, but high-quality evidence is limited and results are mixed.
