Purpose

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.

Methods

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, ¡Ý30. 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 System²⁸ scores.

Results

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 ¡Ý30 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 ¡Ý30 did not have significantly different functional outcomes.

Conclusions

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.

Level of Evidence

Level IV, therapeutic case series.
