Cartilage Regeneration Surgery in Rotherham
Unfortunately, cartilage has no blood supply of its own, meaning it cannot heal itself once damaged by injury or wear and tear. Left untreated, cartilage defects can lead to chronic pain and progressive osteoarthritis.

Cartilage regeneration is a group of advanced orthopaedic procedures designed to repair focal areas of damaged joint cartilage in the knee, ankle or hip. Unlike bone, articular cartilage has no blood supply of its own and cannot heal itself once damaged by injury or wear. At Kinvara Private Hospital in Rotherham, our consultant knee surgeons offer the full range of cartilage repair techniques, from microfracture for small defects to Autologous Chondrocyte Implantation (ACI) and Matrix-Induced Autologous Chondrocyte Implantation (MACI) for larger and deeper lesions, and Osteochondral Autograft Transfer (OATS) for selected cases.
The goal of cartilage regeneration is to restore a smooth joint surface using your own biology, relieve pain and mechanical symptoms, and delay or avoid the need for joint replacement. The procedure is best suited to younger active patients (typically under 55) with a focal cartilage defect (a 'pothole') in an otherwise healthy joint, rather than patients with widespread bone-on-bone arthritis.
We see active adults and athletes from Rotherham, Sheffield, Doncaster, Barnsley, Wakefield, Leeds and the wider Yorkshire region. Most patients are offered an initial consultant consultation within 1 to 2 weeks of enquiry. Self-pay packages are transparent and inclusive, and 0% interest finance is available over 12 months through Humm.
Are You a Candidate for Regeneration?
• The damage is a 'pothole' (focal lesion) surrounded by healthy cartilage.
• The patient is under 55 (biological potential decreases with age).
• The joint alignment is normal (or can be corrected with an osteotomy).
• There is no widespread, 'bone-on-bone' arthritis.
• You are motivated to follow a rigorous 12-month rehabilitation plan.
Transparent Regenerative Pricing
- Competitive fixed-price packages for ACI, MACI, and OAT
- Laboratory fees for cell cultivation included in the package
- Consultant fees and follow-up clinical visits covered
- Post-operative bracing and imaging included
- Flexible financing options available for self-paying patients
Biological Joint Restoration
Cartilage regeneration is distinct from joint replacement. While a replacement 'resurfaces' the joint with artificial materials, regeneration techniques stimulate the body to produce new tissue. This is ideally suited for younger, active patients with focal (localized) damage rather than widespread 'bone-on-bone' arthritis.
Our consultants use high-resolution MRI and diagnostic arthroscopy to determine the size and depth of the defect. This ensures we select the specific biological 'scaffold' or cell-therapy approach that offers the highest chance of long-term success.

Benefits of This Procedure
- Restores a smooth, natural joint surface using your own biology
- Significantly reduces pain and mechanical clicking/locking
- Prevents or delays the onset of early-stage osteoarthritis
- Preserves your natural joint anatomy for as long as possible
- Higher durability for sports and high-impact activities compared to standard repair
- Advanced MACI techniques offer 90%+ success rates for focal lesions
The Procedure
The technique chosen depends on the size of the 'hole' in your cartilage.
- 1
Microfracture: Small holes are made in the bone to release marrow cells, creating a 'super-clot' that forms new tissue.
- 2
ACI (Autologous Chondrocyte Implantation): Healthy cells are harvested in one surgery, grown in a lab, and replanted in a second.
- 3
MACI: Grown cells are 'seeded' onto a specialized collagen membrane which is then glued into the defect.
- 4
OATS (Osteochondral Transfer): Cylinders of healthy bone and cartilage are moved from a low-stress area to the damaged area.
- 5
The new tissue or graft is secured, and the joint is moved gently to ensure smooth tracking.
- 6
A specific rehabilitation brace is applied to protect the healing 'living' tissue.
The Biological Healing Timeline
Recovery Timeline
0 - 6 Weeks
Protection Phase: Crutches are used to prevent weight-bearing while the new cells 'take' and the scaffold stabilizes.
6 - 12 Weeks
Activation Phase: Gradual increase in weight-bearing. Focus on restoring full range of motion through physiotherapy.
3 - 6 Months
Strengthening Phase: Building muscle support around the joint. Low-impact activities like cycling and swimming begin.
9 - 12 Months
Impact Phase: Return to running and pivoting sports once the new cartilage has fully matured.
Key Recovery Points
- Patience is key: Biological tissue takes significantly longer to mature than a metal implant
- A Continuous Passive Motion (CPM) machine may be used at home to 'nourish' the new cells
- Strict adherence to non-weight-bearing is vital for the first few weeks
- Long-term success is highly dependent on dedicated post-operative physiotherapy
Risks & Limitations
Regeneration is a complex biological process. Risks include:
Incomplete Healing
LowThe new tissue may not integrate perfectly with the surrounding cartilage.
Delamination
Very RareThe implanted graft or scaffold could pull away from the bone (extremely rare with modern MACI).
Hypertrophy
ModerateThe new tissue could overgrow, causing a small bump that needs 'trimming' via keyhole surgery.
