Knee Replacement

Knee replacement surgery is one of the most successful operations in orthopaedics, used to relieve pain and stiffness from arthritis or joint damage. The aim is to restore movement, reduce pain, and improve quality of life. Depending on how much of the knee is affected, different types of replacement may be suitable:

Partial Knee Replacement

Also called “unicompartmental knee replacement,” this procedure replaces only the damaged part of the knee (usually the inner or outer side). The healthy bone, cartilage, and ligaments are preserved.

• Benefits: smaller incision, faster recovery, more natural knee movement.
• Best for: patients with arthritis limited to one area of the knee.

Total Knee Replacement

This is the most common type of knee replacement. The worn-out joint surfaces at the end of the femur (thigh bone) and tibia (shin bone) are replaced with smooth, durable implants, and the underside of the kneecap may also be resurfaced.

• Benefits: reliable pain relief, excellent long-term results.
• Best for: patients with widespread arthritis affecting the whole knee.

Patellofemoral Joint Replacement

In some patients, arthritis mainly affects the joint between the kneecap (patella) and the groove it moves in (the femoral trochlea). A patellofemoral replacement resurfaces just this part of the knee.

• Benefits: bone- and ligament-sparing, faster recovery compared with a total replacement.
• Best for: patients with isolated kneecap or trochlea arthritis who still have healthy cartilage elsewhere.

Recovery & Results

Thanks to modern implants and enhanced recovery pathways, most patients are walking on the day of surgery and return home within 0–1 day. Tailored physiotherapy helps you regain strength and confidence, allowing you to return to walking, exercise, and daily life with much less pain.
