Agreement Between Provider-Completed and Patient-Completed Preoperative Frailty Screening Using the Clinical Risk Analysis Index: Cross-Sectional Questionnaire Study

Agreement Between Provider-Completed and Patient-Completed Preoperative Frailty Screening Using the Clinical Risk Analysis Index: Cross-Sectional Questionnaire Study

As part of a quality improvement initiative, we designed and implemented a cross-sectional pilot examination to screen participants aged 65 years and older referred to an outpatient, VHA orthopedic clinic for elective total joint arthroplasty (TJA; eg, total hip or knee arthroplasty) for frailty between November 2022 and August 2023. The primary aim was to examine the agreement between provider-completed and patient-completed RAI-C assessments to inform frailty screening practices at our institution.

Functional Monitoring of Patients With Knee Osteoarthritis Based on Multidimensional Wearable Plantar Pressure Features: Cross-Sectional Study

Functional Monitoring of Patients With Knee Osteoarthritis Based on Multidimensional Wearable Plantar Pressure Features: Cross-Sectional Study

Knee osteoarthritis (KOA) is a degenerative and irreversible joint disease with typical symptoms including pain, stiffness, decreased joint mobility, and gait disturbance [1,2]. These symptoms worsen with the progression of the disease and may lead to serious treatment consequences, such as total knee replacement and the need for corresponding gait correction rehabilitation training.

Effectiveness of Internet-Based Telehealth Programs in Patients With Hip or Knee Osteoarthritis: Systematic Review and Meta-Analysis

Effectiveness of Internet-Based Telehealth Programs in Patients With Hip or Knee Osteoarthritis: Systematic Review and Meta-Analysis

Among the major joints, the hip and the knee are most commonly affected by OA [4]. An estimated 24% of the general adult population has OA [5]. Both hip OA and knee OA are the leading causes of disability worldwide, with hip OA ranked as the 11th-highest contributor to disability worldwide and knee OA ranked as the 38th highest in term of years lived with disability [6]. OA-related disability results in substantial direct costs and mortality.

Development of a 12-Week Unsupervised Online Tai Chi Program for People With Hip and Knee Osteoarthritis: Mixed Methods Study

Development of a 12-Week Unsupervised Online Tai Chi Program for People With Hip and Knee Osteoarthritis: Mixed Methods Study

The knee is the most common lower limb site for osteoarthritis, followed by the hip [2]. Globally, it is estimated that cases of osteoarthritis will increase by 75% for the knee and nearly 80% for the hip by 2050 compared with 2020 [2]. People with hip and knee osteoarthritis often experience pain and impaired function, as well as comorbidities such as depression and anxiety [3,4].

Examining the Feasibility, Acceptability, and Preliminary Efficacy of an Immersive Virtual Reality–Assisted Lower Limb Strength Training for Knee Osteoarthritis: Mixed Methods Pilot Randomized Controlled Trial

Examining the Feasibility, Acceptability, and Preliminary Efficacy of an Immersive Virtual Reality–Assisted Lower Limb Strength Training for Knee Osteoarthritis: Mixed Methods Pilot Randomized Controlled Trial

According to Osteoarthritis Research Society International in 2019, land-based exercise is a core treatment for knee osteoarthritis, for which lower limbs strength training is often recommended [5-7]. In clinical practice, exercise programs often involve initial supervision by a clinician, followed by unsupervised home exercise. Ideally, regular participation in exercise should be one of the long-term goals for knee osteoarthritis; unfortunately, adherence to home exercise is often poor [8].

Telehealth-Supported Exercise or Physical Activity Programs for Knee Osteoarthritis: Systematic Review and Meta-Analysis

Telehealth-Supported Exercise or Physical Activity Programs for Knee Osteoarthritis: Systematic Review and Meta-Analysis

Osteoarthritis is a prevalent degenerative joint disease affecting more than 500 million individuals globally [1], with over 260 million individuals experiencing knee osteoarthritis (KOA) alone, resulting in significant health and socioeconomic burdens [2].

Assessment of the Feasibility of Objective Parameters as Primary End Points for Patients Affected by Knee Osteoarthritis: Protocol for a Pilot, Open Noncontrolled Trial (:SMILE:)

Assessment of the Feasibility of Objective Parameters as Primary End Points for Patients Affected by Knee Osteoarthritis: Protocol for a Pilot, Open Noncontrolled Trial (:SMILE:)

Knee OA is commonly observed in individuals who engage in intense physical sports that require significant strain and loading on their joints, such as American football, soccer, rugby, and gymnastics. A prior injury is a major indication for future development of the disease. Obesity in the upper extremity is often associated with a major cause of knee OA, which results in heavy weight-bearing on the knee [5].

Comparing Anesthesia and Surgery Controlled Time for Primary Total Knee and Hip Arthroplasty Between an Academic Medical Center and a Community Hospital: Retrospective Cohort Study

Comparing Anesthesia and Surgery Controlled Time for Primary Total Knee and Hip Arthroplasty Between an Academic Medical Center and a Community Hospital: Retrospective Cohort Study

Hip and knee osteoarthritis (OA) are pervasive causes of disability and pain globally, and the burden of OA is expected to increase due to population aging and the rising prevalence of obesity [1]. Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are 2 of the most common and well-accepted surgical interventions to improve quality of life for patients with end-stage joint deterioration [2].

A Device for Prehabilitation of Total Knee Replacement Surgery (Slider): Usability Study

A Device for Prehabilitation of Total Knee Replacement Surgery (Slider): Usability Study

In the United Kingdom, in the years 2019-2021, there were 237,934 primary knee replacements with 16,036 knee revision surgeries when the initial surgery was unsuccessful [1]. Patients must perform rehabilitation exercises before and after the operation to ensure proper healing and functioning of the joint. However, up to 70% of outpatients do not complete their physiotherapy, and 14% may not attend a follow-up outpatient appointment [2].
