Closing the Socioeconomic Gap in Massachusetts: Trends in Total Hip Arthroplasty From 2013 to 2015.

To extend insurance coverage to all residents, Massachusetts legislation expanded Medicaid eligibility and added new private insurance categories. To date, no one has analyzed the effect of these changes and compared recent trends in total hip arthroplasty (THA) utilization. Therefore, this study sought to update the current trends of THA utilization in Massachusetts from 2013 to 2015. The Massachusetts State Inpatient Database was queried for all patients who underwent primary THA between 2013 and 2015, and 30,308 patients were identified. Analyzed variables included age, sex, race, Charlson Comorbidity Index, median household income, primary payer, discharge disposition, length of stay, hospital charges, hospital costs, and complications. Categorical and continuous variables were assessed using chi-square analyses and analyses of variance, respectively. Between 2013 and 2015, annual THAs increased from 9361 to 10,562. Race did not vary significantly (P=.447), although an increase in patients using Medicaid and a decrease in patients using other insurance was observed (P<.001). Patients with an income quartile of 1 increased, whereas the number of THA patients in quartile 3 decreased (P<.001). There was a decrease in both hospital charges (P<.001) and costs (P<.001). Mean length of stay decreased (P<.001), and the number of patients with complications decreased (P<.001). Massachusetts has been successful in increasing access to THA procedures for low-income patients and increasing the number of patients who use Medicaid for THAs. The current delivery of health care in Massachusetts has shown improvement for its residents, serving as an example that other states can learn from. [Orthopedics. 2021;44(2):e167-e172.].

Rehabilitation protocols following total knee arthroplasty: a review of study designs and outcome measures.

Total knee arthroplasty (TKA) is among the most common elective procedures performed worldwide. Recent efforts have been made to significantly improve patient outcomes, specifically with postoperative rehabilitation. Despite the many rehabilitation modalities available, the optimal rehabilitation strategy has yet to be determined. Therefore, this systematic review focuses on evaluating existing postoperative rehabilitation protocols. Specifically, this review analyses the study designs, rehabilitation methods, and outcome measures of postoperative rehabilitation protocols for TKA recipients in the past five years. The PubMed, EMBASE, and Cochrane Library databases were queried for studies evaluating rehabilitation protocols following primary TKA. Of the 11,013 studies identified within the last five years, 70 met the inclusion and exclusion criteria. After assessing for relevance and removing duplicates, a final count of 20 studies remained for analysis. Level-of-evidence was determined by the American Academy of Orthopaedic Surgeons (AAOS) classification system. Our findings demonstrated that continuous passive motion and inpatient rehabilitation may not provide additional benefit to the patient or healthcare system. However, early rehabilitation, telerehabilitation, outpatient therapy, high intensity, and high velocity exercise may be successful forms of rehabilitation. Additionally, weight-bearing biofeedback, neuromuscular electrical stimulation, and balance control appear to be beneficial adjuncts to conventional rehabilitation. Postoperative rehabilitation following TKA facilitates patient recovery and improves quality of life. This systematic review analyzed the existing rehabilitation protocols from the past five years. Some studies did not accurately describe the conventional rehabilitation protocols, the duration of therapy sessions, and the timing of these sessions. As such, future studies should explicitly describe their methodology. This will allow high-quality assessments and the conception of standardized protocols.
