This systematic review assessed direct fixation of isolated chondral fragments after acute knee injury in young patients. Eighteen studies involving 76 patients (mean age 14.3 ± 3.7 years) met the inclusion criteria. Across the included reports, healing occurred in 96% of cases, and 86% of patients returned to sports, at an average of 10.3 ± 6.1 months. Younger patients (≤14 years) had higher odds of return to sport (OR: 5.8; P = 0.0427). Functional scores were described as excellent postoperatively, although the authors call for prospective trials to validate these findings.
Key findings
- Healing was reported in 96% of cases across the 18 included studies.
- Return to sports occurred in 86% of patients at an average of 10.3 ± 6.1 months.
- Patients aged ≤14 years had higher odds of return to sport (OR: 5.8; P = 0.0427).
- The review included 76 patients, with a mean age of 14.3 ± 3.7 years.
Why it matters
Chondral-only fragments lack the subchondral bone that traditionally supports fixation, and their management has been uncertain. These pooled reports suggest that fixation can be followed by healing and return to sport in selected young patients. The findings help inform consideration of this approach, while the evidence base remains limited and requires prospective validation.
What to keep in mind
The review included only 18 studies and 76 patients; the authors state that further prospective trials are needed to validate the findings.
