Repair of bucket handle meniscus tears improves patient outcomes versus partial meniscectomy at the time of ACL reconstruction.

Abstract

The aim of this study was to examine demographic and surgical factors that influence patient-reported knee function in patients who undergo anterior crucial ligament reconstruction (ACLR) with concurrent bucket-handle meniscal tear (BHMT) procedures. We hypothesized that repair of BHMT in the setting of concomitant ACLR and shorter time from injury to surgery would lead to improved patient-reported outcomes. Forty-one patients (mean age: 28.0 ± 9.8 years, 72% male) with BHMT at the time of ACLR completed the International Knee Documentation Committee Subjective Knee Form (IKDC-SKF) via online survey at an average of 15.2 months postop. Patient demographics and surgical characteristics, including time from injury to surgery, were compared between repair (n = 22) and meniscectomy (n = 19) groups using one-way analysis of variances; distributions of sex, graft source, BHMT compartment and zone were compared between groups using χ 2 tests. The association between IKDC-SKF score, demographics and surgical characteristics was evaluated using multivariable linear regression. A priori alpha level was p < 0.05. Meniscal repair and meniscectomy groups differed based on graft source and BHMT zone but not IKDC-SKF score (p = 0.085). Patients undergoing ACLR with autograft (p = 0.003) and with red-red zone BHMT (p < 0.001) more often underwent meniscal repair. The regression model demonstrated longer time from injury to surgery (p = 0.049), red-red tear zone (p = 0.04) and meniscectomy (p = 0.008); these were predictive of poorer IKDC-SKF scores. BHMT repair was more likely performed in ACL autograft and on red-red zone tears. Longer time from injury to surgery is an indicator of poorer IKDC-SKF score, as this may increase the risk of concomitant pathologies. White-white zone BHMTs are associated with better IKDC-SKF scores than red-red zone BHMTs, which may be due to the smaller volume of tissue removed during meniscectomy of white-white zone tears and the avoidance of iatrogenic complications of meniscal repair. Level III, therapeutic study.
