■由大量外科医生/诊所进行的前交叉韧带重建(ACLR)与移植物个性化增加和手术时间减少有关。并发症发生率,和总成本。
■探讨主治ACLR后2年外科医生/诊所容量对主观膝关节功能和翻修手术率的影响。
■队列研究;证据水平,3.
■来自瑞典国家膝关节韧带登记处的数据用于研究在2008年至2019年期间接受原发性ACLR的患者。外科医生/诊所根据总病例量的组合进行分类(截止:50个ACLR/外科医生,500个ACLR/诊所)和年容量(截止:29个ACLR/年/外科医生,56ACLR/年/诊所)。最小重要变化(MIC)的阈值,患者可接受的症状状态(PASS),和治疗失败(TF)相对于膝关节损伤和骨关节炎结果评分(KOOS)和KOOS4(KOOS疼痛的平均评分,症状,Sports/Rec,和QoL分量表)被应用。进行校正多变量逻辑回归以评估影响MIC的变量,通过,或KOOS和KOOS4的TF。进行调整后的Cox回归分析以确定后续ACLR的风险比。
■在35,371名患者中,16,317例具有2年的随访结果数据,并纳入其中。与接受低容量手术的患者相比,接受高容量手术的患者的MIC和PASS率明显较高,TF率明显较低:MICKOOS4:70.6%对66.3%;PASSKOOS4:46.0%对38.3%;TFKOOS4:8.7%对11.8%(均P<.02)。获得MICKOOS4(或,0.74;95%CI,0.62-0.88)和PASSKOOS4(或,0.71;95%CI,0.60-0.84)是由小容量外科医生进行的ACLR。诊所体积并不影响达到MIC的几率,通过,或TF。总的来说,804名患者(2.3%)在<2年接受了随后的ACLR,在高容量诊所接受手术的患者中,翻修率明显更高(2.5%vs1.7%;P<.001)。然而,在调整后的Cox回归中,外科医生/诊所容量对随后的ACLR率没有影响.大量外科医生/诊所减少了手术时间,操作时间,围手术期并发症发生率,以及使用血栓预防和非常规抗生素(P<0.001)。
■接受大批量外科医生进行原发性ACLR的患者在主观膝关节功能方面的改善和满意度增加。手术量以外的因素影响后续手术率。患者可能会受益于接受高容量提供者的主要ACLR。
UNASSIGNED: Anterior cruciate ligament reconstruction (ACLR) performed by high-volume surgeons/clinics has been associated with increased graft individualization and decreased operating times, complication rates, and total costs.
UNASSIGNED: To investigate the influence of surgeon/clinic volume on subjective knee function and revision surgery rates at 2 years after primary ACLR.
UNASSIGNED: Cohort study; Level of evidence, 3.
UNASSIGNED: Data from the Swedish National Knee Ligament Registry were used to study patients who underwent primary ACLR between 2008 and 2019. Surgeons/clinics were categorized based on a combination of total caseload volume (cutoff: 50 ACLRs/surgeon, 500 ACLRs/clinic) and annual volume (cutoff: 29 ACLRs/year/surgeon, 56 ACLRs/year/clinic). The thresholds of minimal important change (MIC), Patient Acceptable Symptom State (PASS), and treatment failure (TF) relative to the Knee injury and Osteoarthritis Outcome Score (KOOS) and KOOS4 (mean score of the KOOS Pain, Symptoms, Sports/Rec, and QoL subscales) were applied. Adjusted multivariable logistic regression was performed to assess variables influencing the MIC, PASS, or TF of the KOOS and KOOS4. Adjusted Cox regression analysis was conducted to determine the hazard ratio of subsequent ACLR.
UNASSIGNED: Of 35,371 patients, 16,317 had 2-year follow-up outcome data and were included. Patients who underwent primary ACLR by high-volume surgeons had significantly higher MIC and PASS rates and lower TF rates when compared with patients who underwent the procedure by low-volume surgeons: MICKOOS4: 70.6% vs 66.3%; PASSKOOS4: 46.0% versus 38.3%; and TFKOOS4: 8.7% versus 11.8% (all P < .02). Significantly decreased odds of achieving MICKOOS4 (OR, 0.74; 95% CI, 0.62-0.88) and PASSKOOS4 (OR, 0.71; 95% CI, 0.60-0.84) were found for ACLRs performed by low-volume surgeons. Clinic volume did not influence the odds of reaching MIC, PASS, or TF. Overall, 804 patients (2.3%) underwent subsequent ACLR at <2 years, with significantly higher revision rates among patients operated on at high-volume clinics (2.5% vs 1.7%; P < .001). However, in the adjusted Cox regression, surgeon/clinic volume had no influence on subsequent ACLR rates. High-volume surgeons/clinics had decreased time to surgery, operating time, perioperative complication rates, and use of thromboprophylaxis and nonroutine antibiotics (P < .001).
UNASSIGNED: Patients who underwent primary ACLR by high-volume surgeons experienced increased improvement and satisfaction regarding subjective knee function. Factors other than surgical volume influenced subsequent surgery rates. Patients might benefit from undergoing primary ACLR by high-volume providers.
