Abstract
Purpose: To investigate the influence of surgical volume, and various patient-, injury-, and surgery-related factors, on meniscal treatment strategies in primary anterior cruciate ligament reconstruction (ACLR).
Methods: This retrospective cohort study analyzed patients with concomitant meniscal injuries undergoing primary ACLR, 2008-2022, using data from the Swedish National Knee Ligament Registry. Surgeons and clinics were stratified by total caseload (cutoff: 50 ACLRs/surgeon, 500 ACLRs/clinic) and annual volume (cutoff: 29 ACLRs/year/surgeon, 56 ACLRs/year/clinic). To assess factors influencing medial meniscus (MM) or lateral meniscus (LM) repair, adjusted multivariable logistic regression was conducted, with results presented as odds ratios (OR) and 95% confidence intervals (CI).
Results: 20,699 patients undergoing primary ACLR with concomitant meniscal injuries were included. Lower percentages of meniscus repair were seen among surgeons with low caseload and annual volume (LCLV) (13.3-20.8%) compared to high caseload and annual volume (HCHV) surgeons (19.0-29.8%), and at LCLV clinics (11.1-18.3%) compared to HCHV clinics (21.5-33.8%), all P<0.001. Significantly decreased odds of MM repair were seen for patients operated on by LCLV surgeons (OR 0.82, 95% CI 0.70-0.96; P=0.015) or at LCLV clinics (OR 0.56, 95% CI 0.50-0.64; P<0.001. Similar results were seen for LM repair with LCLV surgeons (OR 0.83, 95% CI 0.69-1.01; P=0.067) and LCLV clinics (OR 0.62, 95% CI 0.53-0.72; P<0.001). Additionally, younger age, female sex, shorter time from injury to surgery, and ACLRs performed more recently were associated with increased odds of repair.
Conclusions: Lower surgical volume significantly decreased the rates and odds of performing meniscal repair during primary ACLR. In contrast, ACLRs performed during more recent years in younger age, female sex, shorter time from injury to surgery, in absence of chondral injuries, and injuries sustained during nonpivoting activities, positively influenced meniscal preservation.
Level of evidence: Level III. Retrospective cohort study.
期刊介绍：
Nowhere is minimally invasive surgery explained better than in Arthroscopy, the leading peer-reviewed journal in the field. Every issue enables you to put into perspective the usefulness of the various emerging arthroscopic techniques. The advantages and disadvantages of these methods -- along with their applications in various situations -- are discussed in relation to their efficiency, efficacy and cost benefit. As a special incentive, paid subscribers also receive access to the journal expanded website.
