In knee osteotomy parts of the thigh bone or femur and the shin bone or the tibia is cut, trimmed and reshaped in order to rectify some defect arising due to multiple reasons . The reasons might be an injury or osteoarthritis of the knee. This helps in relieving the pressure distribution that might have been uneven previously. The major reasons for undergoing an osteotomy are as follows: transferring the weight of the body from the arthritic part of the knee to healthy part of the knee, rectify poor knee alignment, and extend the lifespan of the knee joint.
Osteoarthritis causes misalignment of knee joint. Now, this can shift the pressure on the inner (medial) or the outer (lateral) region and this in return causes excess wear of the cartilage tissues on that side. When the cartilage tissues start wearing out more, the spacing between the knee joint reduces further. Now, to overcome reaching to that condition, osteotomy might serve a suitable procedure. However, the recommendation can only be made by an expert Orthopaedic surgeon . But, at times this is also not the option with highest success rate since the pain relief might not be as expected compared to a total knee replacement.
Again, this process aims to preserve the maximum of your innate anatomy of the knee, which is a good thing, obviously. This will result in better pain relief and functionality after recovery. Osteotomy does not object any constraints on physical activities or from participating in your favorite exercises compared to other total or partial knee replacement procedures. This is a tremendous advantage. In some cases, the recovery might take longer than usual because you shall not be able to put the weight on the leg as in a case of total and partial replacement. Now, the success rate of total and partial replacements has outweighed this process and thus, osteotomy has become lesser in practice.
The process does not involve any sort of replacement or implants. The aim of a tibial osteotomy surgery is to straighten the leg. When the surgery is over, the weight is now evenly spread rather than before and improves the spacing that had narrowed previously wearing away the cartilage more than usual. The procedure must be done at an expert facility to reap the benefits.
