To ortho MDs, PTs, anyone?-knee chondral defects
Quote | Reply
Just want ortho folks to put their thinking caps on...is there any specific condition in the hip(besides weakness, tightness in muscles) that would predispose a person to bilateral medial knee chondral defects? I have a client who has the same defect in both knees not related to trauma. He does have slight varus at both knees, glut med weakness and slight capsular tightness. He is asking about the hip joint itself ie ante or retroversion of the femur. He has not had xrays of the hip as he is painfree there.

The below is not medical advice:

In my experience, non-traumatic knee injuries are a result of biomechanics issues at the hip or knee. You mention the hip, but it is also worth looking south to the ankle as well.

Also, don't rule out genetic predisposition. OA is degenerative is nature and while we can address the biomechanics to alleviate stress, we cannot ignore or prevent the genetic factor.

I'm not sure what your training is, but if you can confidently say there is hip weakness then even slight weakness would contribute to the breakdown process.

Anteversion and retroversion can also be measured visually in prone with someone who is skilled. But severe enough would cause a visual rotation at the tib/femur.

When addressing the hip, I find a lot of people only measure rotation in 90/90 supine and only assess bony morphology. Hip capsules are better assessed in prone/face down with knees bent to 90.

If you and the client are concerned, definitely get them to a specialist.

Good luck!
