Understanding.
Osteoarthritis corresponds to an alteration of the articular cartilage. In the ankle, it can occur some time after a fracture or previous instability. Pain, stiffness, and swelling are possible.
The assessment.
The examination assesses limb mobility and alignment. Weight-bearing radiographs evaluate the joint space and deformities. Additional examinations are sometimes necessary.
Treatments.
Treatment may combine activity modifications, footwear, orthotics, rehabilitation, and pain medication. Injections may be considered. If these are unsuccessful, alignment correction, arthrodesis, or a prosthesis may be considered depending on the patient's profile and joint condition.
Follow-up.
The surgical decision weighs pain, mobility, bone condition, and daily constraints. The postoperative course and risks are explained individually.
Arthrodesis, prosthesis, or axis correction
Arthrodesis fuses the joint to reduce pain, at the cost of reduced mobility. A prosthesis replaces the articular surfaces and aims to preserve movement. An osteotomy can redistribute stress in certain deformities with localized wear.
Post-operative care specific to each intervention
Weight-bearing and immobilization depend on the technique and bone quality. After arthrodesis, fusion is monitored; a prosthesis requires long-term follow-up. Failure of fusion, wear, loosening, or infection may necessitate further surgery.
Your questions.
Is a prosthesis suitable for everyone?+
No. The indication depends in particular on the deformity, the ligaments, the bone, and the activity level.
Does arthrodesis prevent all walking?+
Walking remains possible, but adaptation to uneven terrain and certain movements may be limited.
Does an injection repair cartilage?+
It aims to relieve symptoms; it does not regenerate worn cartilage.
