What are the risks of a tibial tubercle osteotomy?

Risks specific to cutting and moving bone

• Delayed healing or non-union, where the bone takes longer than expected or does not join
• Fracture of the shinbone near the cut, usually linked to heavy loading in the early weeks
• Screw prominence causing discomfort when kneeling, sometimes needing later removal
• Over- or under-correction of kneecap position, which careful planning aims to avoid

Risks shared with other knee operations

These include wound infection, blood clots in the leg or lungs, stiffness, numbness around the scar from small skin nerves, and ongoing kneecap pain if cartilage was already worn. Most are uncommon, and many respond to early treatment.

Smoking, diabetes that is not well controlled and certain medicines slow bone healing. Telling your surgeon about these lets the team prepare.

What lowers the risk

Precise measurement on scans, a cut designed to leave strong bone around the screws, and a clear weight-bearing plan all help. Your part is to use the crutches as instructed, keep the wound clean and dry, take the clot prevention you are prescribed and attend X-ray checks.

In Qatar's heat, keep the dressing dry and avoid long periods outdoors in the first weeks, as sweat can soften the skin around the wound.

When to seek urgent help

Go to emergency care for chest pain or sudden breathlessness. Contact the team quickly for fever, a hot, red or leaking wound, rising calf pain or swelling, or a sudden crack or sharp pain at the front of the shin. At Aman Hospital, Dr. Gelber reviews these concerns promptly during your recovery.
