Purpose The reported incidence of postoperative complications after distal biceps tendon repairs (DBTRs) has been determined largely by retrospective studies. We hypothesized that a large prospective cohort study of DBTRs would demonstrate increased complication rates relative to existing literature values. Secondarily, we hypothesized that most complications would be transient and self-limiting, regardless of the surgical technique employed for the repair.Methods Consecutive patients undergoing acute, primary DBTR from July 2016 to December 2017 were enrolled. The repair technique, postoperative protocol, and follow-up intervals were determined by the individual surgeons' protocols. Demographic information, surgical data, and complications were tabulated prospectively. Exclusion criteria included chronic DBTRs, secondary DBTRs requiring allograft, DBTRs of partial tears, and postoperative follow-up of less than 12 weeks. We included 212 repairs performed by 37 orthopedic surgeons in 3 different subspecialties.Results Sixty-five patients (30.7%) had 73 complications. Fifty patients (44.6%) in the 1-incision group experienced complications compared with 15 (15.0%) in the 2-incision group. Sixty patients (28.3%) developed a minor complication. Fifty-seven patients (26.9%) had sensory neurapraxias, 47 after a 1-incision procedure and 10 after a 2-incision procedure, a statistically significant difference. Of the patients with neurapraxias, 94.7% were resolved or improving at the time of the latest follow-up. Five patients (2.4%) developed a major complication, defined as a return to the operating room in the postoperative period due to deep infection or rerupture. ConclusionsThe complication rate after DBTR appears to be higher than 2 other retrospective studies and is predominantly in the form of transient neurapraxias. This study confirms that there is a higher complication rate in 1-incision techniques as compared with 2-incision techniques.
Background: Functional outcome scores provide valuable data, yet they can be burdensome to patients and require significant resources to administer. The Knee injury and Osteoarthritis Outcome Score (KOOS) is a knee-specific patient-reported outcome measure (PROM) and is validated for anterior cruciate ligament (ACL) reconstruction outcomes. The KOOS requires 42 questions in 5 subscales. We utilized a machine learning (ML) algorithm to determine whether the number of questions and the resultant burden to complete the survey can be lowered in a subset (activities of daily living; ADL) of KOOS, yet still provide identical data. Hypothesis: Fewer questions than the 17 currently provided are actually needed to predict KOOS ADL subscale scores with high accuracy. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Pre- and postoperative patient-reported KOOS ADL scores were obtained from the Surgical Outcome System (SOS) data registry for patients who had ACL reconstruction. Categorical Boosting (CatBoost) ML models were built to analyze each question and its value in predicting the patient’s actual functional outcome (ie, KOOS ADL score). A streamlined set of minimal essential questions were then identified. Results: The SOS registry contained 6185 patients who underwent ACL reconstruction. A total of 2525 patients between the age of 16 and 50 years had completed KOOS ADL scores presurgically and 3 months postoperatively. The data set consisted of 51.84% male patients and 48.16% female patients, with a mean age of 29 years. The CatBoost model predicted KOOS ADL scores with high accuracy when only 6 questions were asked ( R2 = 0.95), similar to when all 17 questions of the subscale were asked ( R2 = 0.99). Conclusion: ML algorithms successfully identified the essential questions in the KOOS ADL questionnaire. Only 35% (6/17) of KOOS ADL questions (descending stairs, ascending stairs, standing, walking on flat surface, putting on socks/stockings, and getting on/off toilet) are needed to predict KOOS ADL scores with high accuracy after ACL reconstruction. ML can be utilized successfully to streamline the burden of patient data collection. This, in turn, can potentially lead to improved patient reporting, increased compliance, and increased utilization of PROMs while still providing quality data.
A 41-year-old female presented with a 3-month history of gradually worsening anterior knee pain, swelling and inability to flex the knee. Magnetic resonance imaging (MRI) revealed a large intra-articular cystic swelling anterior to the anterior cruciate ligament (ACL), extending into the Hoffa's infrapatellar fat pad. Following manipulation under anaesthesia and arthroscopic debridement of the cyst, the patient's symptoms were relieved with restoration of normal knee motion. ACL ganglion cysts are uncommon intra-articular pathological entities, which are usually asymptomatic and diagnosed incidentally by MRI. This is the first reported case of an ACL cyst being so large as to cause a mechanical block to knee flexion.
Background Bilateral distal radius fracture (DRF) is an uncommon injury. We described the outcomes of 10 consecutive cases of bilateral DRF treated with open reduction and internal fixation (ORIF) at our institution. Materials and Methods We retrospectively searched our electronic medical records data for all patients 18 years of age or older treated surgically for bilateral DRF over a 6-year period (2011–2016). Patient demographics, fracture classification, fixation method, postoperative complications, QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand) questionnaire scores, wrist range of motion (ROM), and radiographic measurements of X-rays at final follow-up were collected and analyzed. Results Ten patients (8 women; 2 men; mean age: 63 years) with 20 fractures were assessed. A volar approach for ORIF was used in 90% of cases. Six of 20 (30%) wrists experienced postoperative complications and required hardware removal. Mean QuickDASH score was 24.8 at final follow-up. On average, ROM reached 58-degree extension, 52-degree flexion, 75-degree pronation, and 75-degree supination. Mean measurements of radial shortening, radial inclination, and volar tilt taken from final postoperative radiographs were 1.3 mm, 21.2 degrees, and 7.8 degrees, respectively. Conclusion In bilateral DRF treated with concomitant ORIF, functional outcomes, recovery of wrist ROM, and restoration of radiographic parameters are comparable to those seen in patients with ipsilateral DRF.
Introduction: Predictors of financial costs related to total joint arthroplasty (TJA) have become increasingly important becuase payment methods have shifted from fee for service to bundled payments. The purpose of this study was to assess the relationship between preoperative opioid use and cost of care in primary TJA. Methods: A retrospective study was conducted in Medicare patients who underwent elective unilateral primary total knee or hip arthroplasty between 2015 and 2018. Preoperative opioid usage, comorbidities, length of stay, and demographic information were obtained from chart review. The total episode-of-care (EOC) cost data was obtained from the Centers of Medicare and Medicaid Services based on Bundled Payments for Care Improvement Initiative Model 2, including index hospital and 90-day postacute care costs. Patients were grouped based on preoperative opioid usage. Costs were compared between groups, and multivariate linear regression analyses were performed to analyze whether preoperative opioid usage influenced the cost of TJA care. Analyses were risk-adjusted for patient risk factors, including comorbidities and demographics. Results: A total of 3,211 patients were included in the study. Of the 3,211 TJAs, 569 of 3,211 patients (17.7%) used preoperative opioids, of which 242 (42.5%) only used tramadol. EOC costs were significantly higher for opioid and tramadol users than nonopioid users ($19,229 versus $19,403 versus $17,572, P < 0.001). Multivariate regression predicted that the use of preoperative opioids in TJA was associated with increased EOC costs by $789 for opioid users (95% confidence interval [CI] $559 to $1,019, P < 0.001) and $430 for tramadol users (95% CI $167 to $694, P = 0.001). Total postacute care costs were also increased by 70% for opioid users (95% CI 44% to 102%, P < 0.001) and 48% for tramadol users (95% CI 22% to 80%, P < 0.001). Discussion: This study demonstrated that preoperative opioid usage was associated with higher cost of care in TJA. Limiting preoperative opioid use for pain management before TJA could contribute to cost savings within a bundled model.
