RESUMO
OBJECTIVES: The purpose of this study was to define the rate of preoperative opioid use among patients undergoing hip arthroscopy, ascertain which clinical factors are associated with opioid use, and assess the effect of preoperative opioid usage on preoperative patient-reported outcome (PRO) measures. METHODS: A single institution orthopedic registry was retrospectively analyzed for patients undergoing hip arthroscopy for femoroacetabular impingement (FAI) syndrome with or without labral tear between 2015 and 2022. Patients completed Patient-Reported Outcomes Measurement Information System (PROMIS) in six domains, Numeric Pain Scores (NPS), and Musculoskeletal Outcomes Data Evaluation and Management System expectations domain preoperatively. Patients' charts were reviewed to determine demographic factors and identify any active opioid prescription within 6 weeks before surgery. Bivariate analysis was used to determine associations between preoperative opioid use and baseline PROs. Statistically significant bivariate associations were further tested by multivariate analysis to determine independent predictors. RESULTS: A total of 123 patients were included (age 39.7 â± â12.0 years; 87 females; body mass index 27.4 â± â5.7 kg/m2). There were 21 patients (17%) using opioids preoperatively. Prior orthopedic or other surgery and lower education level were associated with preoperative opioid use. Patients with preoperative opioid use scored statistically significantly worse compared with those without preoperative opioid use on baseline PROMIS Physical Function (38.6 vs 40.5, p â= â0.01), Pain Interference (65.9 vs 60.2, p â= â0.001), Fatigue (60.7 vs 51.6, p â= â0.005), Social Satisfaction (38.2 vs 43.2, p â= â0.007), and Depression (54.2 vs 48.8, p â= â0.01). Preoperative opioid use was also associated with statistically significantly worse preoperative NPS for both the operative hip (6.3 vs 4.6, p â= â0.003) and whole body (3.0 vs 1.4, p â= â0.008). Preoperative opioid use was an independent predictor of worse baseline PROMIS Pain Interference, Fatigue, Social Satisfaction, and NPS for the operative hip. CONCLUSION: Patients using opioids preoperatively had worse baseline PROs for physical function, pain, social satisfaction, and depression than those not using opioids preoperatively. When controlling for confounding variables, preoperative opioid use was independently predictive of worse baseline pain, fatigue, and social satisfaction. LEVEL OF EVIDENCE: Level III, prognostic study.
RESUMO
OBJECTIVES: The goal of this project was to develop and validate a patient-specific, anatomically correct graft for cartilage restoration using magnetic resonance imaging (MRI) data and 3-dimensional (3D) printing technology. The specific aim was to test the accuracy of a novel method for 3D printing and implanting individualized, anatomically shaped bio-scaffolds to treat cartilage defects in a human cadaveric model. We hypothesized that an individualized, anatomic 3D-printed scaffold designed from MRI data would provide a more optimal fill for a large cartilage defect compared to a generic flat scaffold. METHODS: Four focal cartilage defects (FCDs) were created in paired human cadaver knees, age <40 years, in the weight-bearing surfaces of the medial femoral condyle (MFC), lateral femoral condyle (LFC), patella, and trochlea of each knee. MRIs were obtained, anatomic grafts were designed and 3D printed for the left knee as an experimental group, and generic flat grafts for the right knee as a control group. Grafts were implanted into corresponding defects and fixed using tissue adhesive. Repeat post-implant MRIs were obtained. Graft step-off was measured as the distance in mm between the surface of the graft and the native cartilage surface in a direction perpendicular to the subchondral bone. Graft contour was measured as the gap between the undersurface of the graft and the subchondral bone in a direction perpendicular to the joint surface. RESULTS: Graft step-off was statistically significantly better for the anatomic grafts compared to the generic grafts in the MFC (0.0 â± â0.2 âmm vs. 0.7 â± â0.5 âmm, p â< â0.001), LFC (0.1 â± â0.3 âmm vs. 1.0 â± â0.2 âmm, p â< â0.001), patella (-0.2 â± â0.3 âmm vs. -1.2 â± â0.4 âmm, p â< â0.001), and trochlea (-0.4 â± â0.3 vs. 0.4 â± â0.7, p â= â0.003). Graft contour was statistically significantly better for the anatomic grafts in the LFC (0.0 â± â0.0 âmm vs. 0.2 â± â0.4 âmm, p â= â0.022) and trochlea (0.0 â± â0.0 âmm vs. 1.4 â± â0.7 âmm, p â< â0.001). The anatomic grafts had an observed maximum step-off of -0.9 âmm and a maximum contour mismatch of 0.8 âmm. CONCLUSION: This study validates a process designed to fabricate anatomically accurate cartilage grafts using MRI and 3D printing technology. Anatomic grafts demonstrated superior fit compared to generic flat grafts. LEVEL OF EVIDENCE: Level IV.
RESUMO
BACKGROUND: Nicotine in tobacco products is known to impair bone and tendon healing, and smoking has been associated with an increased rate of retear and reoperation following rotator cuff repair (RCR). Although smoking is known to increase the risk of failure following RCR, former smoking status and the timing of preoperative smoking cessation have not previously been investigated. METHODS: A national all-payer database was queried for patients undergoing RCR between 2010 and 2020. Patients were stratified into 5 mutually exclusive groups according to smoking history: (1) never smokers (n = 50,000), (2) current smokers (n = 28,291), (3) former smokers with smoking cessation 3-6 months preoperatively (n = 34,513), (4) former smokers with smoking cessation 6-12 months preoperatively (n = 786), and (5) former smokers with smoking cessation >12 months preoperatively (n = 1399). The risks of postoperative infection and revision surgery were assessed at 90 days, 1 year, and 2 years following surgery. Multivariate logistic regressions were used to isolate and evaluate risk factors for postoperative complications. RESULTS: The 90-day rate of infection following RCR was 0.28% in never smokers compared with 0.51% in current smokers and 0.52% in former smokers who quit smoking 3-6 months prior to surgery (P < .001). Multivariate logistic regression identified smoking (odds ratio [OR], 1.49; P < .001) and smoking cessation 3-6 months prior to surgery (OR, 1.56; P < .001) as risk factors for 90-day infection. The elevated risk in these groups persisted at 1 and 2 years postoperatively. However, smoking cessation >6 months prior to surgery was not associated with a significant elevation in infection risk. In addition, smoking was associated with an elevated 90-day revision risk (OR, 1.22; P = .038), as was smoking cessation between 3 and 6 months prior to surgery (OR, 1.19; P = .048). The elevated risk in these groups persisted at 1 and 2 years postoperatively. Smoking cessation >6 months prior to surgery was not associated with a statistically significant elevation in revision risk. CONCLUSION: Current smokers and former smokers who quit smoking within 6 months of RCR are at an elevated risk of postoperative infection and revision surgery at 90 days, 1 year, and 2 years postoperatively compared with never smokers. Former smokers who quit >6 months prior to RCR are not at a detectably elevated risk of infection or revision surgery compared with those who have never smoked.

BACKGROUND: Contextualizing patient-reported outcomes (PROs) by defining clinically relevant differences is important. Considering that anterior cruciate ligament reconstruction (ACLR) ideally results in the restoration of normal knee function, an assessment of patients' perception of being "completely better" (CB) may be of particular value. PURPOSE: The purpose of this study was to assess the prevalence and characteristics of patients who self-report a CB status after ACLR. Additionally, we aimed to determine whether PROs were associated with a CB status after ACLR as well as to determine CB status thresholds for 2-year and change in values. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: We retrospectively analyzed data from an orthopaedic registry at a single institution. Patients were administered the Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF), PROMIS Pain Interference (PI), and International Knee Documentation Committee (IKDC) Subjective Knee Form preoperatively and at 2 years after ACLR. Additionally, patients completed a CB anchor question at 2 years after ACLR. Thresholds for 2-year and change in PRO scores associated with achieving a CB status were identified with 90% specificity. RESULTS: Overall, 95 of the 136 patients (69.9%) considered their condition to be CB at 2 years after surgery. The 2-year and change in PROMIS PF, PROMIS PI, and IKDC scores were significantly better in the CB group than in the non-CB group. Thresholds associated with a CB status for 2-year PROMIS PF, PROMIS PI, and IKDC scores were more reliable than those for changes in scores and were ≥63, ≤44, and ≥80, respectively. Thresholds for the change in PROMIS PF, PROMIS PI, and IKDC scores were ≥19, ≤-16, and ≥44, respectively. CONCLUSION: The majority of patients reported that they were CB at 2 years after ACLR. This study may serve as a reference for orthopaedic surgeons and researchers when considering outcomes after ACLR.
