RESUMEN
The hand is commonly affected by osteoarthritis (OA). The development and progression of OA are believed to involve inflammation, even in the early stages of the disease. Inflammatory and proinflammatory cytokines have also been shown to be elevated in the flexor tenosynovium of idiopathic carpal tunnel syndrome (CTS). A large percentage of patients with hand OA also have a concomitant CTS. This study evaluated the results of a pulsed electrical joint stimulator in patients who had hand OA with or without CTS. Pain, tenderness, and swelling; grip strength and pinch force; and Patient and Physician Global Assessment and Disabilities of the Arm, Shoulder and Hand (DASH) results were evaluated. The primary efficacy outcome was pain due to OA in the study hand in the past 48 hours. Secondary outcomes consisted of OA pain in the study thumb in the past 48 hours, grip strength, pinch force, and Patient and Physician Global Assessment and DASH results. All 7 outcome parameters improved in OA patients. On physical examination, individual finger and wrist joints had also improved regarding pain, swelling, and tenderness. In the subset of patients with CTS, CTS pain, paresthesia, weakness, and all CTS symptoms had significantly improved. Patient and Physician Global Assessment and DASH results and pinch force were also significantly improved. This pulsed electrical joint stimulator is effective in providing clinically relevant and statistically significant reductions in the signs and symptoms of OA of the hand and CTS. It could be a useful modality for the treatment of patients who have one of these conditions or both. [Orthopedics. 2018; 41(4):e550-e556.].

Patients suffering from quadriceps muscle weakness secondary to osteoarthritis or after surgeries, such as total knee arthroplasty, appear to benefit from the use of neuromuscular electrical stimulation (NMES), which can improve muscle strength and function, range of motion, exercise capacity, and quality of life. Several modalities exist that deliver this therapy. However, with the ever-increasing demand to improve clinical efficiency and costs, digitalize healthcare, optimize data collection, improve care coordination, and increase patient compliance and engagement, newer devices incorporating technologies that facilitate these demands are emerging. One of these devices, an app-controlled home-based NMES therapy system that allows patients to self-manage their condition and potentially increase adherence to the treatment, incorporates a smartphone-based application which allows a cloud-based portal that feeds real-time patient monitoring to physicians, allowing patients to be supported remotely and given feedback. This device is a step forward in improving both patient care and physician efficiency, as well as decreasing resource utilization, which potentially may reduce healthcare costs.

INTRODUCTION: Although resident physicians have a critical role in the daily management of patients, based on their limited experiences, they are thought to potentially create inefficiencies in the hospital. With changes set forth by the Comprehensive Care for Joint Replacement (CJR) program, both teaching and non-teaching hospitals are directly compared on efficiency and outcomes. Therefore, the purpose of this study was to compare outcomes between teaching and non-teaching hospitals in the state of New York. Specifically, we compared: (1) duration of stay; (2) cost of admission; (3) disposition; and (4) 90-day readmission for elective primary total knee arthroplasty (TKA). MATERIALS AND METHODS: Using the New York Statewide Planning and Research Cooperative System (SPARCS) database, 133,489 patients undergoing primary total knee arthroplasty (TKA) between January 1, 2009 and September 30, 2014 were identified. Outcomes assessed included lengths-of-stay and cost of the index admission, disposition, and 90-day readmission. To compare the above outcomes between the hospital systems, mixed effects regression models were used, which were adjusted for patient demographics, comorbidities, hospital, surgeon, and year of surgery. RESULTS: Patients who underwent surgery at teaching hospitals were found to have longer lengths of stay (b=3.4%, p<0.001) and higher costs of admission (b=14.7%; p<0.001). Patients were also more likely to be readmitted within 90 days of discharge (OR=1.64; p<0.001). No differences were found in discharge disposition status for teaching versus non-teaching hospitals (OR=0.92; p=0.081. CONCLUSIONS: The results from this study indicate that at teaching hospitals, a greater number of resources are needed for primary TKA than at non-teaching hospitals. Therefore, teaching hospitals might be inappropriately reimbursed when compensation is linked to competition on economic and clinical metrics. Furthermore, based on this, optimizing reimbursement might inadvertently come at the expense of resident training and education. While some inefficiencies exist as an inherent part of resident training, limiting learning opportunities to optimize compensation can potentially have greater future consequences.

INTRODUCTION: This study evaluated differences in: 1) total episode payments, 2) probability of hospital readmission, 3) probability of inpatient rehab facility (IRF) and utilization, and 4) probability of skilled nursing care facility (SNF) utilization in patients who had disuse atrophy and underwent a total knee arthroplasty (TKA) and either did, or did not, receive preoperative home-based neuromuscular electrical stimulation (NMES) therapy. MATERIALS AND METHODS: We used the Medicare limited dataset for a 5% sample of beneficiaries from 2014 and 2015 to construct episodes-of-care for TKA (DRG-470) patients with disuse atrophy who underwent a TKA during the 30 days prior to hospital admission and 90 days post-discharge. Patients were stratified into those who either did or did not receive pre- and postoperative NMES therapy. An ordinary least square (OLS) model was used to estimate the impact of NMES on total episode. Linear probability models were used to estimate the impact of NMES on SNF or IRF utilization and readmission. RESULTS: A $3,274 reduction in episode payments for patients who used preoperative NMES versus those who did not (p<0.001) was demonstrated. The probability of readmission was 12.7% lower for those who used preoperative NMES therapy versus those who did not (p=0.609). The probability of utilizing IRF and SNF was 56.7% (p=0.061) and 46.4% (p=<0.001) lower for those who used pre- and postoperative NMES versus those who did not, respectively. CONCLUSION: Significant reduction in total episode payments and SNF utilization for TKA patients with disuse atrophy who had NMES therapy was demonstrated.

INTRODUCTION: Patients may experience knee stiffness following total knee arthroplasty (TKA). Non-operative measures, such as more physical therapy and special splints are warranted in such cases. In the event of failure of these measures to restore knee range of motion, more invasive procedures with higher risks, such as manipulation under anesthesia (MUA) or repeat surgery, can be utilized. Thus, it becomes essential to optimize their non-operative measures in order to avoid more invasive, riskier options. Therefore, the purpose of this study was to evaluate and compare: 1) range of motion, and 2) the rate of MUA in patients who either underwent a multi-modal physical therapy regimen (IMMPT) or standard-of-care post-operative therapy (standard) following primary total knee arthroplasty. MATERIALS AND METHODS: We analyzed all non-obese patients who underwent primary TKAs between January 2013 and December 2014 at our institution who started an outpatient physical therapy program within six weeks of their surgery (n = 127 knees). There were 86 women and 41 men who had a mean age of 67 years (range, 42 to 88 years). This cohort was stratified into those who underwent an IMMPT regimen at our institution (n= 47) and those who underwent standard therapy at an outside institution (N = 80). The range of motion and rate of manipulation between the two groups was compared by using Chi-square and Student's t-test, as appropriate. RESULTS: There were similar proportions of those who had an optimal range of motion (≥110 degrees flexion and ≤5 degrees extension) in the IMMPT group as compared to the standard physical therapy cohort (81% vs. 82%). The IMMPT cohort had a significantly lower proportion of patients who underwent MUA as compared to the standard therapy cohort (2% vs. 13%). CONCLUSIONS: This study shows an IMMPT protocol utilizing Astym® therapy (Performance Dynamics, Inc. Muncie, Indiana) is able to significantly reduce the rate of manipulation following a total knee arthroplasty. Furthermore, this IMMPT approach was also able to achieve similar range of motion to the standard physical therapy group while reducing the rate of manipulation, which may indicate similar efficacy in restoring range of motion. Comparative randomized studies are needed to determine the true benefit of this IMMPT protocol.
