What should you know about osteosarcoma proximal tibia?

The proximal tibia is the upper end of the shin bone, where it meets the knee joint. A tumour here may cause persistent pain, swelling, stiffness, or difficulty bearing weight. Nearby muscles, nerves, blood vessels, and the knee joint are considered when scans map the lesion. Pain around the knee has many possible causes, so the location alone does not diagnose osteosarcoma.

Assessment may include an examination, X-ray, magnetic resonance imaging, chest imaging, and a biopsy planned by the specialist team. The biopsy route matters because it is planned with any later operation in mind. Treatment commonly combines chemotherapy with surgery to remove the tumour while preserving useful limb function when that is suitable. Reconstruction may involve a specialist implant or another surgical method, followed by rehabilitation.

Arrange review for ongoing pain near the knee, a noticeable swelling, night pain, reduced knee movement, or a limp that does not settle. Seek urgent help if the leg suddenly becomes unable to bear weight, appears deformed, or develops severe pain after a minor movement. Those symptoms can reflect several conditions, including injury, and require examination rather than self-diagnosis.

Ask how close the tumour is to the knee joint and major nerves or vessels, whether the scans show disease elsewhere, and what biopsy plan is recommended. Ask how Tumour Removal Surgery could affect movement and reconstruction, and when Chemotherapy would be given. Request a rehabilitation outline covering weight-bearing, exercises, and follow-up imaging.
