Predictors of Disparities in Patient-Reported Outcomes before and after Arthroscopic Meniscectomy.

The purpose of this study is to identify predictors of disparities in patient-reported outcome measures (PROMs) before and after arthroscopic meniscectomy. Knee injury and Osteoarthritis Outcome Score (KOOS) was used in this study. All patients who underwent single-knee arthroscopic meniscectomy from January 2012 to March 2018 performed by a single surgeon at an academic safety-net hospital were identified. We excluded patients who had undergone ipsilateral previous knee surgery, bilateral meniscectomy, or concomitant ligament, cartilage, or osteotomy procedures, and those with severe radiographic osteoarthritis in the operated knee, missing preoperative data, or military insurance. Data abstracted from medical records included demographics (age, sex, race, insurance type), clinical characteristics (body mass index, Charlson comorbidity index, and Kellgren-Lawrence [KL] grade), procedure codes, and KOOS assessed before and 90 days after surgery. Multivariable analyses investigated the associations between patient characteristics and the KOOS Pain, other Symptoms, and Function in activities of daily living (ADL) subscales. Among 251 eligible patients, most were female (65.5%), half were of nonwhite race (50.2%), and almost one third were insured by Medicaid (28.6%). Medicaid and black race were statistically significant (p < 0.05) predictors of worse preoperative values for all three KOOS subscales. Medicaid insurance also predicted a lower likelihood of successful surgery, defined as meeting the 10-point minimal clinically important difference, for the KOOS symptoms (p < 0.05) and KOOS ADL (p < 0.05) subscales. Compared with patients without definitive evidence of radiographic osteoarthrosis (KL grade 1), those with moderate radiographic osteoarthritis (KL grade 3) were less likely to have a successful surgical outcome (p < 0.05 for all subscales). Worse preoperative KOOS values predicted worse postoperative KOOS values (p < 0.001 for all subscales) and a lower likelihood of surgical success (p < 0.01 for all subscales). Insurance-based disparities in access to orthopaedic care for meniscus tears may explain worse preoperative PROMs and lower success rates of meniscectomy among Medicaid patients. Patients with meniscus tears and radiological and/or magnetic resonance imaging evidence of osteoarthritis should be carefully evaluated to determine the appropriateness of arthroscopic meniscectomy.

Advantages of a Dedicated Orthopaedic Trauma Operating Room for Diaphyseal Femur Fractures.

OBJECTIVE: To examine the impact of instituting a dedicated orthopaedic trauma operating room (DOTOR) at a Level I trauma center on diaphyseal femur fracture management. DESIGN: Retrospective cohort study. SETTING: Regional, university-based Level I trauma center. PATIENTS: Trauma patients 18-65 years of age who presented between October 2016 and December 2018 (approximately 1 year before and after implementation of the DOTOR) and underwent surgery for diaphyseal femur fractures. One hundred twenty-eight patients met eligibility criteria for inclusion: 60 were treated before and 68 after implementation of the DOTOR. INTERVENTION: Implementation of a DOTOR in October 2017. MAIN OUTCOME MEASURES: Percentage of external fixation versus intramedullary nailing, time from emergency department visit to definitive fixation, duration of surgery, and hospital length of stay. RESULTS: The only significant difference in patient demographics between the before and after groups was mechanism of injury (P = 0.003). Percentage of external fixators as an initial procedure decreased from 15% to 2.9% (P = 0.024). Time to definitive fixation with intramedullary nail decreased from 1083 minutes to 659 minutes (P = 0.002). There was no significant change in median operative time of intramedullary nailing (P = 0.573). Although not statistically significant, hospital length of stay decreased from 7 days to 5.5 days after implementation (P = 0.158). Cost analysis revealed annual cost savings of more than $261,678 for diaphyseal femur fractures alone by implementing a DOTOR. CONCLUSIONS: For diaphyseal femur fractures, instituting a DOTOR at a Level I trauma center reduced the percentage of patients requiring a 2-stage fixation, reduced the time to definitive fixation, and yielded cost savings. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
