This comparative experimental study aims to evaluate the effectiveness of Sensory-Modulated Graded Weight-Bearing Physiotherapy (SMGWBP) in patients with knee osteoarthritis and compare treatment outcomes between male and female participants. Participants will receive a 6-week physiotherapy program with assessments conducted at baseline (pre-intervention), mid-intervention (3 weeks), and post-intervention (6 weeks) using validated outcome measures.

Diagnosed with Grade II or Grade III Knee Osteoarthritis according to Kellgren-Lawrence Classification.
Ability to ambulate independently without assistive devices.
Mild to moderate pain intensity with a Visual Analogue Scale score less than seven.
History of knee surgery within the previous six months.
Neurological disorders affecting balance, gait, or proprioception.
Severe cardiovascular disease limiting participation in exercise.
Rheumatoid arthritis or other inflammatory arthritic conditions.

Sensory-Modulated Graded Weight-Bearing Physiotherapy
BehavioralA structured six-week Sensory-Modulated Graded Weight-Bearing Physiotherapy Programme consisting of three supervised sessions per week (18 sessions total). Each session includes warm-up, sensory modulation, proprioceptive training, graded weight-bearing strengthening, functional mobility exercises, and cool-down activities. The programme progresses through three phases: Weeks 1-2 focus on sensory activation and proprioceptive training; Weeks 3-4 on graded weight-bearing strengthening; and Weeks 5-6 on functional weight-bearing integration. Exercises are progressed according to participant tolerance, pain severity, and functional performance. Both male and female groups receive the same intervention.
