Osteotomy surgery — literally "bone cutting" — is a joint-preserving procedure that realigns the mechanical axis of the lower limb to redistribute load from the arthritic compartment of the joint to the healthier, less-damaged compartment. By reducing the load on the damaged area, osteotomy relieves pain, slows the progression of arthritis, and in younger patients, delays or prevents the need for joint replacement — allowing them to remain active for years before the inevitable replacement surgery.
The most common osteotomy procedures in the lower limb are: high tibial osteotomy (HTO) — correcting varus (bow-legged) alignment in medial compartment knee OA; distal femoral osteotomy (DFO) — correcting valgus (knock-kneed) alignment in lateral compartment knee OA; and periacetabular osteotomy (PAO) — reorienting the acetabulum in hip dysplasia to prevent progressive OA.
Osteotomy is most appropriate for younger (under 55–60 for HTO, under 40 for PAO), active patients who have unicompartmental joint disease with good range of motion and intact ligamentous stability. It is a joint-preserving operation — preserving the patient's own joint tissues — that aims to restore the quality of life of an active patient while allowing future joint replacement when the time eventually comes.
India's orthopaedic centres have experienced osteotomy surgeons, with HTO a commonly performed procedure at major knee centres.
Types of Osteotomy
High Tibial Osteotomy (HTO): the most commonly performed lower limb osteotomy. In varus knee alignment (bow-legged), the majority of body weight passes through the medial (inner) compartment of the knee, accelerating OA of the medial femoral condyle and medial tibial plateau. HTO corrects this by cutting the tibia just below the joint line and opening or closing the wedge to shift the mechanical axis laterally — from the medial to the neutral or slight lateral compartment. An opening wedge HTO (the most common modern technique) uses a saw or osteotome to make a cut from medial to lateral in the proximal tibia; the cut is then gradually opened to the required correction angle and held in place with a locking plate. Bone graft (or bone substitute) fills the wedge gap. The plate is removed after bone union (typically 12–18 months).
Distal Femoral Osteotomy (DFO): in valgus knee alignment (knock-kneed), load concentrates in the lateral compartment. DFO corrects this by creating a closing wedge at the distal femur, removing a wedge of bone from the lateral side and closing the gap to shift the mechanical axis medially — reducing loading on the lateral compartment.
Periacetabular Osteotomy (PAO, Ganz osteotomy): in developmental hip dysplasia (shallow acetabulum causing edge loading), the acetabulum is mobilised by four bone cuts around the acetabular socket, allowing it to be reoriented to improve femoral head coverage and reduce peak contact pressures at the anterolateral edge. PAO is the most technically demanding of the osteotomy procedures, requiring pelvic surgery access and microscopically precise bone cuts around the hip socket.
Femoral osteotomy for cam/pincer impingement (femoral derotation osteotomy) addresses rotational deformities of the femur that cause femoroacetabular impingement and contribute to labral tearing and OA in younger patients.
Osteotomy Surgical Technique
High tibial osteotomy (opening wedge technique) is performed under general or spinal anaesthesia, typically taking 60–90 minutes. The leg is placed in a slightly flexed position on the operating table; the medial proximal tibia is exposed through a short medial incision. Under fluoroscopic guidance, the osteotomy cut is made from the medial tibial cortex — stopping approximately 10 mm short of the lateral cortex, which acts as a hinge. A calibrated spreader is inserted in the osteotomy gap and gradually opened to the planned correction angle (confirmed on fluoroscopy by alignment of the mechanical axis from the femoral head to the ankle). The gap is filled with a bone graft substitute block (TCP, HA) or autologous iliac crest bone graft; a locking plate (TomoFix or equivalent) is applied across the osteotomy and secured with locking screws. The leg is placed in a non-padded bandage; the patient begins immediate controlled weight-bearing.
Distal femoral osteotomy: a closing wedge of the lateral distal femur is removed with an oscillating saw; the femur is closed and fixed with a lateral blade plate or locking plate.
Periacetabular osteotomy requires a specialised surgical approach (usually ilioinguinal or modified Smith-Petersen) and is performed under general anaesthesia in 2–3 hours by surgeons specifically trained in this procedure. The four osteotomy cuts are made sequentially; the acetabular fragment is mobilised; reoriented to the planned coverage angle; and held with 3–4 large cannulated screws under fluoroscopic and intraoperative radiographic guidance.
Procedure Steps
- Full-length standing leg X-ray; mechanical axis deviation calculated; correction angle planned
- CT for 3D bone structure assessment (PAO) or bone stock quality (HTO)
- Spinal or general anaesthesia; fluoroscopy available; osteotomy performed
- Correction angle confirmed on fluoroscopy; locking plate fixation
- Immediate post-operative standing X-ray confirming alignment correction
- Partial weight-bearing with crutches for 6 weeks; X-ray at 6 weeks and 12 weeks
- Hardware removal at 12–18 months after confirmed bone union (optional)

High tibial osteotomy in the USA costs $15,000–$25,000. In India, HTO with a TomoFix locking plate costs $3,000–$5,000 all-inclusive. DFO costs $3,500–$5,500. PAO (more complex) costs $6,000–$10,000. Hardware removal (if required at 12–18 months) costs an additional $1,000–$2,000.
Recovery & Follow-up
HTO recovery: partial weight-bearing on crutches for 6 weeks; progressive full weight-bearing from 6 weeks; normal walking at 10–12 weeks; return to running at 6 months; return to sport at 9–12 months when X-ray confirms complete bone union. The bone wedge fills with mature bone by 10–12 weeks; the plate can be removed at 12–18 months once the osteotomy is completely healed.
PAO recovery: crutches for 6–8 weeks; progressive weight-bearing at 8–10 weeks; full weight-bearing at 12 weeks; return to sport at 6–9 months. PAO recovery is longer due to the extent of the bony surgery around the pelvis.
Recovery Tips
- Partial weight-bearing compliance in the first 6 weeks is critical — premature loading causes the osteotomy to close and lose correction
- Attend X-ray review at 6 and 12 weeks — bone union must be confirmed before advancing to full weight-bearing
- Physiotherapy starts from day 1 for range of motion and straight-leg raises; quadriceps strengthening begins at 4 weeks
- Maintain vitamin D and calcium supplementation to support bone healing
- Do not smoke — smoking significantly delays bone union and is a major risk factor for non-union after osteotomy
Risks & Complications
HTO risks include: non-union (failure of the osteotomy to heal — approximately 5%; higher in smokers and diabetics); under- or over-correction (inaccurate alignment achieved — affects outcome and may require revision); delayed union; fibular nerve injury at the proximal fibula (peroneal nerve — foot drop, usually temporary); hinge fracture (the planned lateral cortex hinge fractures completely during opening, requiring careful fixation); deep vein thrombosis; infection; and knee stiffness. PAO carries pelvic surgery risks including: blood loss (sometimes requiring transfusion); nerve injury (obturator nerve, femoral nerve, lateral cutaneous nerve of thigh); and the potential for inadvertent entry into the hip joint during the periacetabular bone cuts (requiring careful technique).

Patients arrive with their correction angle calculated and implant pre-selected, optimising operative efficiency.
Frequently Asked Questions
Am I too young for knee replacement? Should I have an osteotomy?
For patients under 55 with isolated medial compartment knee OA, varus malalignment, and a good range of motion, HTO is often the better choice than TKR — it preserves the natural joint, allows continued high-level activity, and defers TKR for 10–15 years in successful cases. TKR in young patients requires revision (re-replacement) at 15–20 years, and revision TKR is more complex than primary. Choosing HTO now may mean you only ever need one TKR (at 65–70), rather than a primary TKR at 50 followed by a revision at 65–70.
How long does the osteotomy correction last before I need a knee replacement?
Published long-term data shows that approximately 60–70% of patients who have HTO do not need TKR at 10 years, and 40–50% do not need TKR at 15–20 years. The best predictors of long-term success are: younger age at osteotomy; good pre-operative range of motion; limited lateral compartment involvement; intact cruciate ligaments; adequate correction (overcoming the varus to achieve 3–5 degrees of valgus mechanical axis); and maintenance of a healthy body weight. When TKR is eventually required, the previous HTO does not compromise the technical conduct of TKR.
Does the plate from an osteotomy need to be removed?
Hardware removal after HTO is not mandatory — many patients keep the plate permanently without symptoms. Removal is considered if the patient has plate-related discomfort (the proximal medial tibia is a subcutaneous area where the plate head can be felt), or if the patient wishes to resume contact sport where the plate might be at risk of fracture. Hardware removal is a minor procedure under general anaesthesia, typically performed at 12–18 months after confirmed bone union, and has a rapid recovery (normal activity in 2 weeks).
