Background Single-stage medial meniscus allograft transplantation (MAT) with concomitant anterior cruciate ligament reconstruction (ACLR) is a technically challenging procedure for management of knee pain and instability in younger patients, but clinical and functional outcomes data are sparse. The purpose of this study was to assess surgical and patient-reported outcomes following concomitant ACLR and medial MAT. Methods We conducted a retrospective case series of patients who underwent medial MAT with concomitant primary or revision ACLR at our institution from 2010 to 2021 and had minimum 12-month follow-up. Complications, reoperations, visual analog scale (VAS) pain, satisfaction, Lysholm score, return to sport, and return to work outcomes were assessed. Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference, Pain Intensity, and Physical Function Scores were used to measure patients’ functional status relative to the US population. P-values < 0.05 were considered significant. Results The cohort consisted of 17 knees of 16 individual patients. The cohort was majority male (82.4%) with mean age of 31.9 years (range 19–49 years) and mean body mass index (BMI) of 27.9 kg/m2 (range 22.5–53.3 kg/m2). Mean follow-up time was 56.8 months (range 13–106 months). Most patients underwent revision ACLR (64.7%). The 1-year reoperation rate was high (23.5%), with two patients (11.8%) tearing their meniscus graft. Patient-reported outcomes indicated low VAS pain (mean 2.2), high satisfaction (mean 77.9%), and fair Lysholm score (mean 81.1). Return to work rate was high (92.9%), while return to sport rate was low (42.9%). Postoperative PROMIS scores were comparable or superior to the national average and correlated significantly with patient satisfaction (p < 0.05). Conclusions The concomitant ACLR and MAT procedure is associated with excellent knee pain and functional outcomes and high rate of return to work after surgery, though the 1-year reoperation rate is high and rate of return to sport is low. Level of evidence: IV.
Introduction: Needle arthroscopy has been introduced in recent years as an alternative to magnetic resonance imaging (MRI) for the evaluation of knee and shoulder conditions. It has continued to evolve at a rapid rate with newer generation models making in-office integration simple. As MRI can sometimes prove inconclusive, it is worthwhile to consider these alternative options for evaluating musculoskeletal pathology as a primary diagnostic tool.Purpose: The purpose of this study is to evaluate the specificity and sensitivity of needle arthroscopy in diagnosing intra-articular shoulder and knee pathology in a small case series of patients who ultimately underwent surgical arthroscopy.Methods: A retrospective, single-centre, single-surgeon, cohort study was performed over a three-year period from August 2018 to June 2021. During this time, diagnostic needle arthroscopy was performed on patients with suspected shoulder or knee pathology based on MRI findings and clinical exams. These patients subsequently underwent standard surgical arthroscopy.Results: Thirty-four patients were included in the study. There were 35 joints included, 25 shoulders and 10 knees, with a mean age of 41.88 +/-11.32 years and BMI of 29.33 +/-6.27 in the shoulder group and a mean age of 45.5 +/-14.54 and BMI of 31.5 +/-4.94 in the knee group. When evaluating shoulder pathologies, needle arthroscopy showed a sensitivity of 0.93 for rotator cuff tears, 1.00 for labral tears and 1.00 for loose bodies. Needle arthroscopy for the shoulder was found to be 100% specific for all shoulder pathologies. Needle arthroscopy for the knee was found to have a 1.00 sensitivity for detecting chondral defects and 0.80 sensitivity for meniscal tears. There were once again no false positive needle arthroscopy findings amongst the knee group.Conclusion: Needle arthroscopy is an accurate diagnostic tool for the evaluation of intra-articular knee and shoulder musculoskeletal pathology. It can provide a potential solution for MRI-derived diagnostic inaccuracies that can lead to missed pathologies or unindicated procedures. It is less invasive than surgical arthroscopy and should be considered a useful tool in the armamentarium of orthopedic surgeons.
Background and Purpose: Ketogenic diet (KD) improves seizure control in patients with drug-resistant epilepsy. As increased mitochondrial levels of glutathione (GSH) might contribute to a change in seizure susceptibility, we quantified changes of absolute GSH levels in the brain by in vivo 1H magnetic resonance spectroscopy (1H MRS) and correlate that with degree of seizure control in patients on KD.Methods: Five cognitively normal adult patients with drug-resistant epilepsy were initially included and 2 completed the study. Each patient was evaluated by a neurologist and registered dietitian at baseline, 1, 3, and 6 months for seizure status and diet adherence after initiation of a modified atkins diet. Multiple metabolites including GSH were quantified using LCModel (version 6.3-1P; Stephen Provencher, Oakville, ON, CA) on a short echo time single-voxel 1H MRS in parieto/occipital grey matter and parietal white matter on a 3 Tesla General Electric magnet prior to starting the ketogenic diet and at 6 months.Results: Both patients (42-years-old male and 35-years-old female) demonstrated marked increases in absolute GSH level in both gray matter (0.12 to 1.40 and 0.10 to 0.70 international unit [IU]) and white matter (0.65 to 1.50 and 0.80 to 2.00 IU), as well as 50% improvements in seizure duration and frequency. Other metabolites including ketone bodies did not demonstrate consistent changes.Conclusions: Markedly increased levels of GSH (7-fold and 14-fold) were observed in longitudinal prospective study of two adult patients with intractable epilepsy with 50% seizure improvement after initiation of ketogenic diets. This pilot study supports the possible anticonvulsant role of GSH in the brain.
Healthcare disparities have become a notable topic of research in the last decade. Within Orthopedic Surgery, and more specifically, spine surgery, minority patients experience these disparities via increased lengths of stay, higher 30-day hospital readmission rates, and poor patient reported outcomes. One possible cause for these disparities is the implicit biases held by these patients’ physicians. The aim of this study is to assess the current state of implicit racial biases amongst orthopedic surgeons at various stages of training. To do this, 4th year medical students, majority applying into orthopedic surgery, as well as Orthopedic Surgery residents and attendings at an urban academic medical center were provided an anonymous, voluntary survey to document the results of an online Implicit Association Test specifically focusing on race. Our results demonstrated that medical students and residents mirror the general population with an inherent preference for white over black people. Attendings differed significantly from the general population with little to no preference for either race. While there are various hypotheses for these findings, the results suggest that there is a strong need for further research surrounding implicit bias and healthcare disparities in orthopedic surgery among both future and current physicians. With a better understanding of how to shift these biases, achieving equity in patient care can become a more attainable goal.
