The purpose of this study was to evaluate the impact of body mass index (BMI) on early functional results of patients who undergo isolated partial meniscectomy.
The functional results for 1,090 patients who underwent partial meniscectomy, in 2 different orthopaedic clinics, were evaluated retrospectively. The study includes cases with arthroscopic partial meniscectomy for isolated meniscal tears; patients with concomitant knee pathology were excluded. Three hundred forty-one (31%) patients with isolated lateral meniscal tears, 628 (58%) patients with isolated medial meniscal tears, and 121 (11%) patients with both medial and lateral meniscal tears underwent arthroscopic partial meniscectomy. We divided these patients into 3 subgroups on the basis of their BMI; <26, between 26 and 30, ≥30. Preoperative functional results were compared with 1-year postoperative follow-up results using the International Knee Documentation Committee (IKDC),(26) Lysholm Knee Scale,(27) and Oxford Scoring System(28) scores.
According to all 3 knee scales, age, side of lesion, and tear type had no effect on functional outcome. When compared with the group with BMI <26, the patients with BMI between 26 and 30 and the patients with BMI ≥30 had significantly worse outcomes as measured by the IKDC, Oxford Scoring System, and Lysholm Knee Scale scores. Patients with BMI between 26 and 30 and ≥30 did not have significantly different functional outcomes.
Short-term outcomes after arthroscopic partial menisectomy reflect significant improvement in subjective outcome. However, patients with moderate or significant obesity (BMI >26) have inferior short-term outcomes compared with nonobese patients.

本研究旨在评估体重指数（BMI）对接受单纯半月板部分切除术患者早期功能结果的影响。
回顾性评估了在 2 家不同骨科诊所接受半月板部分切除术的 1090 名患者的功能结果。该研究包括接受关节镜下单纯半月板撕裂半月板部分切除术的病例；排除了伴有膝关节病变的患者。341 例（31%）患者为单纯外侧半月板撕裂，628 例（58%）患者为单纯内侧半月板撕裂，121 例（11%）患者为内外侧半月板撕裂。我们根据 BMI 将这些患者分为 3 个亚组；<26、26-30、≥30。使用国际膝关节文献委员会（IKDC）、（26）Lysholm 膝关节量表和（27）牛津评分系统（28）评估术前功能结果与 1 年术后随访结果。
根据所有 3 个膝关节量表，年龄、病变侧和撕裂类型对功能结果均无影响。与 BMI<26 的组相比，BMI 在 26-30 之间和 BMI≥30 的患者的 IKDC、牛津评分系统和 Lysholm 膝关节量表评分的功能结果明显更差。BMI 在 26-30 之间和≥30 的患者的功能结果没有显著差异。
关节镜下半月板部分切除术后短期结果反映了主观结局的显著改善。然而，中度或重度肥胖（BMI>26）的患者与非肥胖患者相比，短期结局较差。
