Development of a mobile application to improve exercise accuracy and quality of life in knee osteoarthritis patients: a randomized controlled trial.

Introduction: Knee Osteoarthritis (OA) is a degenerative joint disease that needs consistent exercise and an accurate understanding of the condition for long-term maintenance. While the accessibility of outpatient care is essential for disease management, many patients lack the resources to receive adequate healthcare. To address this challenge, we developed a not-for-profit interactive mobile application that provides a disease-specific educational background and a structured exercise regimen to patients.

Imageless robotic-assisted total knee arthroplasty accurately restores the radiological alignment with a short learning curve: a randomized controlled trial.

Purpose: The study compared a novel imageless robotic-assisted total knee arthroplasty (RATKA) and conventional TKA by considering (1) radiological outcomes, (2) outliers of radiological outcomes, and (3) learning curve.

Mechanical alignment, radiological implant positioning, and outliers were analyzed for radiological outcomes.

Onlay Patellar Resurfacing in a Posterior-Stabilized Total Knee Arthroplasty Increases Patellar Crepitus Complication: A Randomized, Controlled Trial.

Background: Patellar crepitus (PC) is a potentially problematic complication after total knee arthroplasty (TKA) more commonly occurring with a posterior-stabilized (PS) prosthesis. Patellar resurfacing has been reported to reduce PC complications; however, no study has compared the PC complication rates between 2 different resurfacing techniques, namely inlay and onlay.

Methods: A prospective, randomized controlled trial was conducted to compare the PC complication between inlay and onlay patellar resurfacing techniques.

When to Use a Condylar Constrained Insert in Non-Stemmed Posterior-Stabilized Total Knee Arthroplasty.

Backgroud: The constrained insert with non-stemmed tibial and femoral components can be used in the modern total knee arthroplasty (TKA) when soft-tissue balance and adequate stability from a posterior-stabilized (PS) insert cannot be achieved. This study aimed to identify the prevalence and predictive factors associated with the constrained insert use during primary TKA for varus deformity.

Methods: From August 2016 to March 2019, 554 primary TKAs were consecutively performed by one surgeon.

Background: The benefit of patellar denervation (PD) in patellar resurfacing total knee arthroplasty (TKA) is still debatable. This prospective, randomized controlled trial investigated whether circumferential PD should be performed in patellar resurfacing TKA.

Methods: A total of 241 patients who underwent unilateral TKA were randomized into PD or non-PD groups.

Indwelling urinary catheterization was unnecessary in non-drainage total knee arthroplasty: a randomized controlled trial.

Purpose: To investigate whether catheterization remains necessary in non-drainage total knee arthroplasty (TKA) using combined spinal epidural anesthesia (CSEA) with a short-acting opioid by comparing (1) incidences of postoperative urinary retention (POUR), and (2) postoperative clinical outcomes between retained urinary catheter (UC) and non-retained urinary catheter (non-UC) groups.

Methods: A total of 230 patients underwent non-drainage TKA using CSEA with fentanyl were randomized into UC and non-UC groups (115 patients each, 115 knees each). Incidences of POUR, clinical outcomes (intraoperative intravenous fluid, operative time, whole blood loss, urinary tract infection (UTI), and length of stay) were evaluated after the operation, while range of motion (ROM) and Knee society score (KSS) were evaluated 3- and 6-month postoperatively.

Comparison of Clinical Outcomes of Different Rates of Infusion in Caudal Epidural Steroid Injection: A Randomized Controlled Trial.

Study Design: Prospective randomized controlled equivalence trial.

Purpose: To compare the clinical outcomes between patients with lumbosacral radiculopathy that received caudal epidural steroid injection (CESI) at injection rates of 40 mL/min (fast rate) and 20 mL/min (slow rate) and to identify the complications associated with these different CESI rates.

Overview Of Literature: CESI is widely used for chronic low back pain with lumbar radiculopathy.

Resurfacing in a Posterior-Stabilized Total Knee Arthroplasty Reduces Patellar Crepitus Complication: A Randomized, Controlled Trial.

Background: Patellar crepitus (PC) is a common complication after total knee arthroplasty (TKA) using a posterior-stabilized (PS) prosthesis. While numerous factors have been associated with PC development after PS-TKA, patellar resurfacing (PR) which directly impacts the patellofemoral joint kinematics has been underinvestigated. A prospective, randomized, controlled trial was conducted to (1) compare the PC incidence in PR and non-PR PS-TKA, (2) determine the time of PC presentation in PS-TKA, (3) identify radiographic parameters associated with PC, and (4) compare clinical outcomes of patients with and without PR.

Low-level laser therapy with a wrist splint to treat carpal tunnel syndrome: a double-blinded randomized controlled trial.

The efficacy of low-level laser therapy (LLLT) was evaluated in a total of 66 patients with mild to moderate carpal tunnel syndrome (CTS) with a double-blinded randomized controlled study. The patients were randomly assigned into two groups. Group I received 15 sessions of a gallium-aluminum-arsenide laser treatment at a dosage of 18 J per session over the carpal tunnel area with neutral wrist splint.

Midterm outcomes of electromagnetic computer-assisted navigation in minimally invasive total knee arthroplasty.

Background: A combination of two emerging technologies, computer-assisted navigation and minimally invasive surgery, in total knee arthroplasty has gained increasing interests from orthopedic surgeons around the world. To date, there has never been any midterm study for clinical and radiographic outcomes from using an electromagnetic computer-assisted navigation system. In this study, we aimed to systematically compare clinical and radiographic outcomes of minimally invasive surgery in total knee arthroplasty (MIS-TKA) performed with and without electromagnetic computer-assisted navigation at immediate and midterm follow-ups.

Prediction of deep vein thrombosis after total knee arthroplasty with preoperative D-dimer plasma measurement.

Background: Despite prophylaxis, deep vein thrombosis (DVT) still occurs frequently after elective knee surgery. Hence, it would be helpful if the high-risk DVT patients could be identified before surgery so the adequate prophylaxis could be given. A normal plasma D-dimer level effectively rules out acute DVT patients who were classified as having low clinical probability.

Anatomical landmark of descending genicular artery for minimidvastus approach of the knee.

Objective: To determine the anatomical course of descending genicular artery and to identify a safety zone for minimidvastus approach.

Material And Method: Forty-eight knees from twenty-four fresh cadavers were dissected to identify the descending genicular artery, and to measure the distance between such artery and superomedial pole of the patella as well as the entry angle of such artery to the perpendicular line of the vertical axis of the patella.

Results: The average distance between the descending genicular artery and superomedial pole of the patella was 8.
