The objective of the study was to compare the effects of active release technique and bent leg raise on hamstring flexibility, functional outcomes, and pain in patients with knee osteoarthritis.

Knee Osteoarthritis is a common progressive degenerative joint disease. Muscular weakness and other structural abnormalities can cause low back pain. Hamstring muscle being a postural muscle has an increased tendency to become tight. In this study, participants with knee osteoarthritis having hamstring tightness were included. Active Release Technique and Bent Leg Raise technique have been used to increase flexibility in hamstrings in these patients with knee osteoarthritis.

Inclusion Criteria:

• Diagnosed patients of Knee Osteoarthritis
• Hamstring length less than 160 degrees
• Minimum history of 3 months
• Willing to participate

Exclusion Criteria:

• Patients who have passive knee extension more than 160 degrees
• Patients with less than 3 months history
• Patients who have osteoarthritis of other than the knee joint
• Patients with history of fracture
• Patients with post surgical history
