Return to Sport in Professional Athletes After Cartilage Restoration Surgery of the Knee
Evidence strength 4 of 5
Systematic review + meta-analysis · n = 11 studies / 476 · 39.9 wk mean follow-upMACI ITSELFFull text →What it can tell you
The professional-athlete return picture after cartilage restoration: pooled 84.3% returned across 11 studies and 476 athletes.
What it cannot
What returning meant — 82% of the component studies omitted return-to-sport criteria and nearly half lacked any definition. And it says almost nothing about women: under 4% of the pooled athletes were female.

Read it like a sceptic
Mean follow-up under a year (39.9 weeks) — mean time to graft failure is around 22 months; the follow-up ends before the risk window does.
Professional athletes have rehabilitation resources most readers don't; their return rate is a ceiling, not an expectation.
