Who qualifies for MACI knee surgery?Patients aged 18–55 with deep focal cartilage damage (Grade III-IV, >2 cm²) qualify for MACI if their knees are structurally sound—stable ligaments, correct alignment, no generalised osteoarthritis—and conservative treatment has failed. The procedure is two-stage, with extended rehabilitation required.Patients aged 18–55 with deep focal cartilage damage (Grade III-IV, >2 cm²) qualify for MACI if their knees are structurally sound—stable ligaments, correct alignment, no generalised osteoarthritis—and conservative treatment has failed.

ChondroFiller injection versus cartilage surgeryChondroFiller injection achieves 30 IKDC improvement with 3–8% reoperation and 0% complications; microfracture carries 41% reoperation rates with declining long-term outcomes; ACI/MACI matches functional gains but brings 17% complications and 37% reoperation.ChondroFiller injection achieves 30 IKDC improvement with 3–8% reoperation and 0% complications; microfracture carries 41% reoperation rates with declining long-term outcomes; ACI/MACI matches functional gains but brings 17% complications and 37% reoperation.

Who qualifies for OATS knee surgeryOATS transplants hyaline cartilage harvested from a low-load zone of the same knee to repair focal defects. The donor site heals with fibrocartilage, creating potential for catching, locking, or anterior knee pain.OATS transplants hyaline cartilage harvested from a low-load zone of the same knee to repair focal defects.

Is OATS knee surgery worth itCartilage damage beyond a certain point cannot self-repair. OATS transplants healthy cartilage plugs to replace it, with 85–93% achieving clinical success and improvements sustained at ten and twenty years, though 10–15% experience persistent donor-site pain.Cartilage damage beyond a certain point cannot self-repair.

Choosing ACI, MACI or single‑stage cell surgeryACI and MACI are two-stage repairs for localised full-thickness cartilage defects, while single-stage techniques place cells or cell-rich material into the defect in one operation. MACI has the strongest long-term follow-up, but single-stage methods still rest mainly on smaller, less comparable series.ACI and MACI are two-stage repairs for localised full-thickness cartilage defects, while single-stage techniques place cells or cell-rich material into the defect in one operation.

Microfracture is now usually limited to very small defects, while AMIC, MACI, OATS and OCA are chosen by lesion size, depth and joint health.

MACI knee surgery cost and insuranceMACI is a two-stage knee cartilage repair, so costs rise with the biopsy, lab cell expansion and later implantation rather than a single operation. In 2023, 89% of cases were approved on the first insurance submission, with approval typically taking 25–30 days.MACI is a two-stage knee cartilage repair, so costs rise with the biopsy, lab cell expansion and later implantation rather than a single operation.

This two-stage procedure effectively addresses knee cartilage defects caused by injury or degenerative conditions like osteoarthritis. Symptoms such as persistent pain, swelling, and reduced mobility often necessitate MRI and arthroscopic evaluations to determine MACI suitability. Despite mild short-term side effects like swelling and pain, the treatment has shown significant promise in restoring knee function. Recovery includes a structured rehabilitation programme, crucial for optimal outcomes. Early intervention and maintaining a healthy lifestyle can prevent further cartilage damage. Proper aftercare minimises risks, ensuring successful recovery and improved quality of life.

Hip osteoarthritis treatment before replacement surgeryUK clinical guidance requires documented completion of conservative care — physiotherapy, weight management, analgesia — before accepting a total hip replacement referral. Surgical timing is determined by functional impact, not imaging severity.UK clinical guidance requires documented completion of conservative care — physiotherapy, weight management, analgesia — before accepting a total hip replacement referral.
