Purpose: The purpose of this study was to examine the effect of deep flexion on the long-term durability of a high-flex ceramic implant in total knee arthroplasty.
Methods: Five hundred and five consecutive knees replaced with a Bi-Surface knee system (Kyocera Medical, Osaka, Japan) were divided into two groups according to the range of flexion by 135° postoperatively. Comparison of implant durability was made between the high- and low-flexion groups after a minimum ten year follow-up.
Results: With revision for any surgery as the end point, the survival rates at ten years were 95.5% and 96.2% in the high- and low-flexion group, respectively (p = 0.63). With revision for mechanical failure as the end point, survival rates were 98.7% and 98.5%, respectively (p = 0.94).
Conclusion: Implant survival rate was similar for both groups. Deep flexion seemed not to affect long-term durability.

Decreased Association Between Patellar Axial Malalignment and Patellar Height and Increased Association Between Patellar Axial Malalignment and Tibial Tubercle-Trochlear Groove During Weightbearing.

Background: Nonweightbearing preoperative assessments avoid quadriceps contraction that tends to affect patellar motion and appear to be inaccurate in quantifying anatomic factors, which can lead to incorrect corrections and postoperative complications.
Questions/purposes: (1) Does the relationship of patellar axial malalignment and other anatomic factors change during weightbearing? (2) What anatomic factor was most strongly correlated with recurrent patellar dislocation during weightbearing?
Methods: This prospective, comparative, observational study recruited participants at our institution between January 2023 and September 2023. During this time, all patients with recurrent patellar dislocations received both weightbearing and nonweightbearing CT scans; control patients who received unilateral CT scans because of injuries or benign tumors received both weightbearing and nonweightbearing CT scans.
The Usability and Effect of a Novel Intelligent Rehabilitation Exergame System on Quality of Life in Frail Older Adults: Prospective Cohort Study.

Background: Aging in older adults results in a decline in physical function and quality of daily life. Due to the COVID-19 pandemic, the exercise frequency among older adults decreased, further contributing to frailty. Traditional rehabilitation using repetitive movements tends not to attract older adults to perform independently.

Surgical site infection (SSI) after total hip and knee arthroplasty (THA/TKA) is a major complication leading to morbidity and mortality. Perioperative irrigation, frequently with antiseptic compounds including povidone-iodine (PI), is the standard of care in reducing SSI. Evidence supporting the value of PI versus nonantiseptic substances varies.

Background: Although there is a known correlation between obesity and revision risk following total knee arthroplasty (TKA), there is an ongoing debate regarding the appropriateness of denying TKA solely based on the body mass index (BMI) of a patient. Our aim was to determine whether a patient's American Society of Anesthesiologists (ASA) class predicts their risks of early all-cause revision and revision for periprosthetic joint infection (PJI) following primary TKA, independent of their BMI.
Methods: Data from the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) were obtained regarding all patients who underwent primary TKA for osteoarthritis in Australia from January 1, 2015, to December 31, 2022.
Hemostatic effect of oxidized regenerated cellulose vs. topical tranexamic acid in total knee arthroplasty-a prospective randomized controlled trial.

Department of Knee Joint Surgery, Xi'an Honghui Hospital, Xi'an Jiaotong University, Xi'an, Shaanxi, China.
Aims: This study compared the hemostatic effects and complications of oxidized regenerated cellulose (ORC) and topical TXA in total knee arthroplasty (TKA), thus providing a reference for the use of ORC as an alternative hemostatic agent to TXA in TKA.
Methods: A total of 105 patients were included in this study and randomized into blank control, ORC, and TXA groups. The primary outcomes were total blood loss, hemoglobin drop (Hb drop), transfusion rates, and incidence of thrombosis.
