When the knee is malaligned, it puts excessive strain on certain parts of the joint; which parts depends upon what direction it is malaligned in.
When the knee is bowed, we call it varus deformity. This causes extra strain on the inside half of the knee and can lead to early arthritis. It can be treated by a repositioning procedure known as a high tibial osteotomy. This is quite a big operation but should be considered in cases of moderate to severe bowing in patients whose ligaments are all working and the joint is not too stiff.
When the knee is in a knock-knee position we call it valgus deformity.This causes extra strain on the outside half of the knee and, again, can lead to early arthritis. It can be treated by a repositioning procedure known as a distal femoral osteotomy. This is a big operation but can be considered in cases of severe deformity (again it is only done in patients whose ligaments are all working and the joint is not too stiff).
The final common case of malalignment is problems with the kneecap (patella) As the patella tracks up and down on the femur, this is commonly called patella maltracking. This tends to cause anterior knee pain and can be very disabling. There are lots of different causes and lots of treatment options, including therapy and many surgical procedures. Mr. Miles sees a lot of patients with these problems and is able to perform the range of surgical options. The surgery options include tibial tubercle osteotomy, medial patellofemoral ligament reconstruction and lateral releases.
