Knee osteoarthritis (KOA) is a joint degenerative arthropathy, characterized by cartilage degeneration of knee joint. Ligustrazine is an effective component of traditional Chinese medicine chuanqiong. It is reported that ligustrazine is used as a kind of anti-inflammatory medicine in folk prescription, especially in the treatment of knee osteoarthritis. The study is aimed to study the therapeutic effect of ligustrazine mediated by nanoparticle on knee osteoarthritis and its impact on MMPs and upstream NF-B signaling pathway in synovial fluid. Nanoparticle-mediated system is a kind of nano traditional Chinese medicine preparation, which is made by taking nanoparticle and combining with the effective components, effective parts, raw materials, and their compounds in a certain way. We found that the combination of nanoparticle and ligustrazine can improve its bioavailability and targeting, reduce the adverse reactions in the treatment of knee osteoarthritis. The ligustrazine mediated by nanoparticle can effectively alleviate knee osteoarthritis by reducing the level of MMPs in synovial fluid and the expression of NF-B in upstream NF-B signaling pathway.

Background: Wearable activity-measurement devices are increasingly popular among the public, but there is little information regarding their use among patients undergoing sports medicine procedures. The purpose of this study was to compare accelerometer-measured data with traditional patient-reported measures and to determine the trajectory of physical activity from before surgery to 1 year after anterior cruciate ligament reconstruction.
Materials And Methods: Adult patients undergoing primary anterior cruciate ligament reconstruction were enrolled in this prospective cohort pilot study.
Evaluating Surgeon-influenced Factors for Total Knee Arthroplasty Value-based Reimbursement.
J Am Acad Orthop Surg
January 2025
From the Rothman Orthopaedic Institute at Thomas Jefferson University Hospital, Philadelphia, USA (Sutton, Lizcano, Krueger, Courtney, and Purtill), and the Department of Orthopaedic Surgery, Hospital for Special Surgery, New York, USA (Austin).
Introduction: Clinical outcome measures used under value-based reimbursement models require risk stratification of patient demographics and medical history. Only certain perioperative patient factors may be influenced by the surgeon. The study evaluated surgeon-influenced modifiable factors associated with achieving literature-defined KOOS score thresholds to serve as the foundation of the newly established alternative payment models for total knee arthroplasties (TKA).

Department of Orthopedics, Brown University, Providence, RI.
Objectives: Knee Osteoarthritis (OA) is one of the most frequently encountered conditions in orthopedic practice. This study aimed to validate the Knee Intake Patient Survey (KIPS), a short-form questionnaire designed to assist in the initial diagnosis and treatment stratification for knee OA.
Methods: Patient intake survey results from a single adult reconstruction clinic were retrospectively analyzed alongside clinical diagnoses and treatment recommendations.
High failure rate in meniscal repair when preceding anterior cruciate ligament reconstruction: An analysis of two-stage surgery for concomitant ACL injury and traumatic meniscus tear.
Knee Surg Sports Traumatol Arthrosc
January 2025
Capio Artro Clinic, FIFA Medical Centre of Excellence, Sophiahemmet Hospital, Stockholm, Sweden.
Purpose: To investigate the failure rate, predictive factors associated with failure and clinical outcomes after a two-stage surgery; meniscus repair followed by subsequent anterior cruciate ligament (ACL) reconstruction (ACLR).
Methods: Patients with a concomitant traumatic meniscus tear and ACL injury who underwent a two-stage surgery between January 2015 and January 2021 were identified. The primary outcome was meniscal repair failure, defined as a reoperation (re-repair or resection).
Effect of weight loss and liraglutide on neutrophil gelatinase-associated lipocalin levels among individuals with overweight and knee osteoarthritis: Exploratory analyses of a randomized controlled trial.
Osteoarthr Cartil Open

The Parker Institute, Copenhagen University Hospital - Bispebjerg and Frederiksberg, Denmark.
Objective: Obesity is a major risk factor for osteoarthritis (OA). Adipose tissues may be linked to OA development through secretion of potential proinflammatory cytokines including neutrophil gelatinase-associated lipocalin (NGAL). Our objective was to assess changes in serum NGAL after a low-calorie diet (LCD) and subsequent glucagon-like peptide 1 receptor agonist (GLP-1 RA) treatment.
