Cartilage Repair Surgery

Cartilage repair surgery aims to restore a damaged joint surface, but healing depends on the defect, procedure, and rehabilitation.

Articular cartilage is the smooth covering that lets joint surfaces glide and helps distribute load. A focal defect can cause pain, swelling, catching, or reduced activity. Surgery may smooth unstable tissue, create small channels in the underlying bone, transfer an osteochondral graft, or implant cartilage cells. These approaches are different and are selected after imaging and examination.

Recovery is rehabilitation-led. You may need a brace, crutches, or limits on weight-bearing while the repair is protected. Physiotherapy works on swelling control, joint movement, muscle activation, balance, and then gradual strength and sport-specific loading. Progress is based on the repair and your examination rather than a single calendar date.

Potential problems include persistent pain or swelling, stiffness, infection, blood clots, irritation from hardware, or failure of the repair tissue to mature. A graft or implanted cells may not integrate as intended. New calf swelling, chest pain, fever, wound drainage, or a locked joint needs prompt assessment.

The aim is to improve symptoms and joint function by treating a defined cartilage defect, not to guarantee a completely normal joint. Results depend on defect size and location, alignment, meniscus and ligament health, age, activity demands, and rehabilitation. A repair can provide durable benefit, but symptoms may recur or arthritis may still develop elsewhere.

Cartilage has limited natural healing capacity, which is why a focal defect may need a specialized plan. Magnetic resonance imaging and sometimes arthroscopy help define the surface, underlying bone, and other structures. A [Collagen Scaffold](/materials/collagen-scaffold/) may be used in selected techniques to support repair tissue.

It may be considered for a person with a symptomatic, localized defect who has not improved enough with rehabilitation and activity modification. It can be discussed for a [Knee Cartilage Injury](/conditions/knee-cartilage-injury/) or selected [Osteochondritis Dissecans](/conditions/osteochondritis-dissecans/). Diffuse arthritis, poor alignment, untreated ligament instability, or an unhealthy joint may require a different strategy first.

The team confirms the target joint and anaesthetic plan. Through an arthroscopic or open approach, the surgeon inspects the defect, prepares its edges and base, and performs the selected repair. Graft, cell, or scaffold material may be secured when indicated. The wounds are closed, and a brace or weight-bearing plan is explained before discharge.

The early phase protects the repair while restoring safe movement and reducing swelling. The middle phase builds muscle control, strength, and walking tolerance. Later rehabilitation adds impact, direction changes, or sport-specific work only when testing supports it. Full return to demanding activity can take many months and should be cleared by the treating team.

Tell the team about smoking, diabetes, blood-thinning medicines, previous operations, and any clotting history. Follow weight-bearing and brace instructions closely; progressing too quickly can overload healing tissue. Seek urgent advice for breathing difficulty, marked calf pain or swelling, fever, or a rapidly swollen joint.

Depending on the defect, options may include structured physiotherapy, activity modification, weight management when relevant, pain relief, injections, or alignment or joint-replacement procedures. Observation can be reasonable when symptoms are mild and function is preserved. Imaging and examination help distinguish a repairable focal problem from wider joint disease.

Seek an orthopedic surgeon experienced in cartilage and sports-joint care. Bring imaging reports and a record of symptoms, swelling, previous treatment, and activity goals. Ask which repair is proposed, what restrictions are expected, how physiotherapy will be supervised, and what would count as successful progress.
