Overview
About Deformity Correction in Advanced Arthritis
Long-standing knee arthritis commonly leads to varus deformity (bow legs) or valgus deformity (knock knees) as the joint space narrows asymmetrically. These deformities worsen pain, accelerate joint damage, and significantly impair gait. Treatment options include corrective osteotomy (bone realignment) for younger patients with localised disease, or joint replacement with deformity correction for advanced cases.
Key Benefits
Corrects visible joint malalignment causing abnormal gait and appearance
Osteotomy preserves the natural joint in younger, active patients
Joint replacement simultaneously corrects deformity and relieves arthritis pain
Improved weight distribution reduces stress on the joint after correction
Significantly improved walking ability and quality of life post-correction
Frequently Asked Questions
What is varus and valgus deformity?
Varus (bow legs) means the knees bow outward, putting excess stress on the inner knee. Valgus (knock knees) means the knees angle inward. Both can result from or worsen arthritis.
What is an osteotomy?
An osteotomy is a surgical procedure that cuts and realigns the bone to shift body weight away from the damaged compartment of the knee. It is most suitable for younger, active patients with localised arthritis.
Is deformity correction always surgical?
Mild deformities can sometimes be managed with physiotherapy, bracing, and footwear modifications. Significant deformities causing pain and functional limitation usually require surgical correction.
Can joint replacement correct the deformity too?
Yes — total knee replacement can correct varus and valgus deformities simultaneously with the replacement. It is the preferred option for patients with advanced arthritis combined with significant deformity.
What is recovery like after osteotomy?
Recovery after osteotomy takes longer than joint replacement — typically 3–6 months. Weight bearing is restricted initially and physiotherapy is essential for a successful outcome.
