Background:Thigh muscle strengthening is important in knee osteoarthritis patients, this study will investigate if hip abductors strengthening can improve knee pain, function and quadricepsisometric strength comparable to knee extensor strengthening. Methods/Design: A pretest- posttest two groups study designwill be applied in Faculty of Physical Therapy ,Cairo University. 70 patients with knee osteoarthritis will be recruited with age ranges from 50-70. They will be randomized into 2 groups

Sample size: 70 patients based on power analysis using Gpower software. Conclusion: Strengthening hip abductors only offer significant effects reaching same target with less risk of knee OA progression from knee extensor strengthening.
