Abstract
Purpose
To report the first big series on the prevalence of chondral lesions in Latin America and describe the outcomes based on reoperation and failure rate.
Methods and Materials
Retrospective cohort study. We reviewed the clinical records of 3,809 consecutive knee arthroscopies performed from 2002 to 2019 in a third level referral center. Information regarding chondral lesion prevalence, location, size, grade, and treatment was obtained. Chondral lesions were classified as “not treated” if debridement or no treatment was mentioned in the clinical record; and “treated” if a cartilage repair technique was performed. The reoperation rate related to the chondral lesion and the failure rate (defined as the need of a total knee replacement) for each group was documented after a long-term follow-up.
Results
The mean age of our patients was 37 years (8-64 years). Chondral lesions were found in 60.27% of all arthroscopies, with 67% of them being severe lesions (ICRS grade III-IV). The average lesion size was 2.37 cm2 (0.5 - 16 cm2). Lesions were mainly located in the patella (37%) and the medial femoral condyle (27%). Associate procedures were performed in 81% of the cases. 22.3% of the chondral lesions were treated and 77.6% of lesions were not treated. After a mean follow-up of 10 years (2-19 years) post arthroscopy, the reoperation rate was 15% for osteochondral autograft transplantation (OAT), 9.06% for microfracture, 8.96% for untreated lesions and 2.56% for matrix-assisted autologous chondrocyte transplantation (MACT). Failure rate was 3.32% for microfracture, 2.45% for untreated lesions, and 0% for MACT and OAT.
Conclusion
The prevalence of chondral lesion was 60.27% in 3,809 knee arthroscopies performed in a third referral center of Latin America. After 10 years follow-up post arthroscopy, OAT had the highest reoperation rate (15%), microfracture the highest failure rate (3.32%) and MACT the lowest reoperation and failure rate, with 2.56 and 0% respectively.
