Knee osteotomies

Knee osteotomies

Knee osteotomy is a surgical procedure that involves cutting and reshaping the bones around the knee joint to change the alignment of the leg. The goal of a knee osteotomy is to relieve pain and improve function by redistributing weight and reducing stress on damaged or arthritic parts of the knee.

There are two main types of knee osteotomies

High Tibial Osteotomy (HTO)

Indications: High tibial osteotomy is commonly performed for medial compartment osteoarthritis of the knee, where the inner side of the knee joint is affected. It is particularly considered in younger, active individuals with early-stage arthritis.

Procedure: During an HTO, the surgeon removes a wedge of bone from the upper part of the tibia (shinbone) to correct the alignment. This helps to shift the weight away from the damaged part of the knee, reducing pain and potentially slowing down the progression of arthritis.

Outcome: High tibial osteotomy aims to delay the need for more extensive procedures like total knee replacement in younger patients with localized arthritis.

Distal Femoral Osteotomy (DFO)

Indications: Distal femoral osteotomy is less common and is performed for lateral compartment osteoarthritis, where the outer side of the knee joint is affected.

Procedure: In a distal femoral osteotomy, the surgeon reshapes the end of the femur (thighbone) to alter the alignment, addressing the weight distribution and reducing stress on the affected area.

Outcome: Distal femoral osteotomy aims to provide pain relief and improve function in cases where the lateral compartment of the knee is primarily affected.

Knee osteotomies are typically considered in patients with localized arthritis, deformities, or malalignments, especially in younger individuals who may not be ideal candidates for total knee replacement due to their age. The success of the procedure depends on careful patient selection, appropriate surgical technique, and adherence to rehabilitation protocols post-surgery. Orthopedic surgeons evaluate each case individually to determine if a knee osteotomy is the most suitable option for the patient's condition.
