Obesity increases meniscal allograft transplant failure rates.



to analyze the effect of obesity and other clinical factors on the outcome of meniscal allograft transplantation (MAT) with transosseous fixation.


a retrospective cohort study was carried out. Patients who had undergone MAT were included. The variables assessed were: age at the time of the transplant, side, gender, transplanted meniscus (lateral / medial), body mass index (BMI), smoking status and previous surgeries. Lysholm, Tegner and IKDC test outcomes, and patient satisfaction were recorded. Image assessment was carried out using plain standing X-Rays and MRI.


34 patients fulfilled the inclusion criteria. The mean follow-up time was of 73.1 SD 45 months. Patients with a BMI > 30 underwent more frequently medial meniscal transplants (88.9 %; p=0.047). Obese patients had a significantly lower IKDC (48.6 SD 19.9 vs. 62.2 SD 13.0, p= 0.044, power: 47.5%) and Lysholm (60.3 Sd 19.2 vs. 80.0 SD 13.0, p= 0.002, power: 91.3%) scores compared with non-obese patients. The satisfaction and Tegner scores were also lower in obese patients (55.6 % vs 80.0, p=0.201, and 2.8 SD 1.0 vs. 3.8 SD 1.9, p=0.151, respectively); however, these differences were not statistically significant. Obese patients had higher rates of meniscal transplant failure compared to non-obese patients (adjusted hazard ratio 5.4, CI 95% 1.1-29.1, p). No differences were observed between obese and non-obese patients regarding age, gender, side, smoking status, and follow-up time


A BMI > 30 kg/m2 is associated with a higher risk of MAT failure. Moreover, better knee functional results in non-obese patients compared to obese individuals following a MAT were found.
Level of evidence: III. Retrospective cohort study.
