Knock Knee Osteotomy: What to Expect

In knock knees, the leg axis can place more load through one part of the knee. During an osteotomy, the surgeon makes a controlled cut in a selected bone, adjusts its angle, and holds the new position while it heals. The exact bone and technique depend on the location of the deformity and the condition of the joint.

The decision is not based on appearance alone. Examination, standing alignment images, pain pattern, activity limits, age, and cartilage condition all matter. People with [Knee Osteoarthritis](/conditions/knee-osteoarthritis/) may discuss whether realignment could suit their joint or whether another option is more appropriate.

Before surgery, ask about smoking, medicines that affect bleeding, dental or skin infections, and arrangements for help at home. Recovery commonly includes a protected period for bone healing, followed by progressive weight bearing, knee motion, and physiotherapy. The plan varies with the operation and follow-up imaging.

A fixation device keeps the corrected position stable. This may include a [Plate and Screws](/materials/plate-and-screws/). Use crutches or other aids exactly as instructed, keep the wound protected, and attend follow-up visits so healing and alignment can be checked. The broader procedure is described under [Osteotomy](/treatments/reconstructive-orthopedic-surgery/osteotomy/).

Contact the team promptly for increasing wound redness, drainage, fever, worsening pain, new numbness, a cold or discoloured foot, calf swelling, or breathlessness. After discharge, follow the written plan for weight bearing and exercises; sudden changes in pain or function should not be ignored.

Ask which bone will be corrected, how the target angle is chosen, what fixation will be used, and how long protected weight bearing may last. Ask about physiotherapy, work and driving restrictions, wound care, follow-up imaging, and what alternatives fit your symptoms and joint condition.
