Post operative Flexion deformity {FFD} in patient is B/L total knee replacement{TKR}is very common. most of the patient land up with 20 -30 degrees of flexion deformity.
what is hte cause of deformity.
1. Hamstring tightness is not always the cause of knee felxion deformity.
2. Post operative they have hug swelling around the knee. Swelling is the part of recovery it helps in healing. But the swelling causes distension of the joint capsule and reduces the osteokinetic movement of the joint.
3. Stiffness of knee joint: there is severe stiffness because of swelling, immobility, reduced joint play.
4. We may find 10 to 20 degrees of loss of full extension in supine lying examination.But in standing and walking patients shows flexion up 20-40 degrees.
5. Change in the angle of Pull of quadriceps: Swelling causes change the angle pull of quadriceps that also make it to extend the knee completely.
6. Weakness of quadriceps: early stages knee extensors show extension lag, due weakness.
7. Change in Muscle set Point of quadriceps. because of swelling, change in angle of pull and weakness, quadriceps are never able to work in outer range. because of this muscle set point changes and it is not able work in outer range.
8. This cause knee flexion increase in standing & walking {Weight Bearing} compared to supine or sitting examination.

This is an informative post. I was suffering from knee pain and got chiropractic treatment. The chiropractor in Mississauga treated me so well that felt really good after the very first session. Since then, I am a big fan of this therapy.
