MECHANICAL TRACTION APPLIED BEFORE VERSUS AFTER THERAPEUTIC EXERCISES IN PRIMARY KNEE OSTEOARTHRITIS
Sponsor: Cairo University
Summary
To study the effect of application of mechanical traction before versus after therapeutic exercises and exercise alone ,on pain severity , disability , knee joint range of motion , knee joint position sense , knee isometric muscle strength and functional performance in patients with primary knee OA.

Interventions
Group A: Therapeutic exercise group
therapeutic exercises (Stretching and Strengthening Exercises for all major lower-limb muscles), Stretching will be performed(Rectus femoris, hamstring, calf muscle) for 1 set of 3 repetitions, 30 seconds hold, a rest period of 30 seconds between repetitions. Stretching will be carried out slowly and in a controlled manner until the feeling of mild tightness or discomfort. Strengthening exercises for (Knee extensors, knee flexor, hip extensor, hip flexor, hip abductor, hip external rotator, ankle dorsi flexor and plantar flexor) will be performed for 3 sets of 10 repetitions each, 10 seconds hold, a rest period of 2 seconds between repetitions and 30 seconds between sets. The resistance will be applied using sandbags and therabands of different weight and tension. The initial resistance will be determined based on 10RM, and the resistance will progress each week
Group B: mechanical traction followed by therapeutic exercise
Mechanical traction will be applied for 20 minutes continuously in the supine lying position with the affected knee flexed at 25-30° (where joint structures are the most relaxed and the maximum amount of joint play is enabled) by a wedge placed under the thigh, before starting, the angle will be measured using a goniometer. The thigh will be stabilized by a strap and the leg will be held by the specially designed greave with the weight of traction hanging throughout the pulley system. The initial traction force will be set at 10% of the body weight. Traction force will be increased each week by 1% of body weight if the patient could tolerate then the same exercise of the firs group will be applied .
Group C: therapeutic exercise followed by mechanical traction
This group will receive the same therapeutic exercises of 1st group followed by mechanical knee joint traction
