Targeted Rehabilitation Versus Standard Care in Managing Medial Knee Pain and Varus Malalignment: A Randomized Control Trial

Medial knee pain with varus alignment is common in active adults and is associated with increased medial joint loading, cartilage loss, and progression of knee osteoarthritis. Conventional rehabilitation typically emphasizes quadriceps strengthening and general physiotherapy, which may reduce pain and improve function but often has limited effect on abnormal frontal-plane loading and alignment in individuals with varus deformity. Targeted neuromuscular and alignment-focused exercise programs that emphasize hip and lower-limb muscle control may better address underlying biomechanical contributors to medial knee loading. This randomized controlled trial will compare a traditional/conventional physical therapy program with a specific, alignment-focused exercise program in active adults aged 30-55 years who have medial knee pain, mild to moderate varus deformity, and Kellgren-Lawrence grade 1-3 knee osteoarthritis. Approximately 80 participants will be recruited from an outpatient setting and randomized (1:1) to receive either traditional rehabilitation or a targeted exercise protocol focusing on hip adductors and internal rotators. The supervised intervention will last 6 weeks, with follow-up assessments at 12 weeks, 6 months, and 1 year. The primary outcome is the Oxford Knee Score, with secondary outcomes including lower-extremity function, pain, quality of life, muscle strength, and radiographic alignment.
