Extensor mechanism realignment Cost in India

The cost of extensor mechanism realignment in India typically ranges from $500 to $6,000 USD, depending on the hospital, city, and type of procedure.

Extensor mechanism realignment is surgery to improve how the kneecap (patella) moves in its groove. The extensor mechanism includes the thigh muscle, the kneecap and the patellar tendon. The cost usually depends on:

• Procedures combined: for example, a ligament reconstruction and a bone realignment.
• Implants: screws to hold bone in a new position.
• Hospital stay: often one night.
• Brace and physiotherapy: after surgery.

Realignment can involve different procedures. Ask for a quote based on the exact operation planned.

Realignment is considered for kneecap instability, where the kneecap repeatedly slips out of place, or for pain caused by poor tracking. Contributing factors may include:

• A high-riding kneecap (patella alta): the kneecap sits higher than usual.
• A shallow groove: in the thigh bone.
• A torn MPFL: the ligament that holds the kneecap on the inner side.
• Leg alignment: the position of the shin bone attachment.

Physiotherapy is usually tried first, especially after a first dislocation.

Realignment may involve one or more procedures:

• MPFL reconstruction: replacing the torn ligament with a tendon graft.
• Tibial tubercle osteotomy: moving the bony attachment of the patellar tendon.
• Lateral release or lengthening: loosening tight tissue on the outer side.
• Trochleoplasty: deepening a very shallow groove, in selected cases.

Frimley Health NHS Foundation Trust notes that tibial tubercle osteotomy is sometimes combined with MPFL reconstruction.

Recovery depends on the procedures performed. After tibial tubercle osteotomy, Frimley Health advises a brace locked straight for walking for up to 6 weeks and at least 6 weeks off work.

Risks include infection, stiffness, blood clots, ongoing knee pain and recurrence of instability. Over- or under-correction is also possible.
