Aim: To investigate the feasibility of testing exercise-induced hypoalgesia (EIH) in a field setting. The effect of knee pain on EIH was also explored.
Design: Within-group pre-post design.
Materials And Methods: Fourteen athletes (8 male, 6 female) competing at an international level in badminton were tested on the sideline during an in-season training session. Participants completed questionnaires and a single leg decline squat to evaluate the presence of knee pain. A blinded examiner measured PPT over the quadriceps muscle before and after two conditions (3-minute quiet rest and 3-minute isometric wall squat).
Results: The exercise protocol was completed by 13 (93%) participants. Mean (SD) exertion was 8.4 (1.7), and mean thigh pain was 7.9 (2.0) at 3 minutes. Very high reliability was observed for PPT collected before and after rest (ICC 0.94, 95% CI 0.85, 0.98). PPT significantly increased by 22.4% (95% CI 15.1, 29.7) after wall squat but not after rest. Relative increases in PPT were similar in participants with and without knee pain on single leg decline squat (22.2% versus 22.6%, 7 participants each).
Conclusion: Simple, field-based tests of endogenous analgesia are feasible and could provide new opportunities to evaluate an athlete's risk of persistent pain.

Institute of Sport, Exercise & Health, Tianjin University of Sport, Tianjin, China.
Background: Patellofemoral pain syndrome (PFPS) is a common disorder affecting the lower extremity. This study aimed to compare the effects of functional strength training (FST) and standard strength training (SST) in PFPS patients.
Methods: Forty college students (aged 18-30 years) with PFPS and no exercise habits were randomized into FST group (n = 20) and SST group (n = 20).

J Orthop Surg Res
January 2025
Department of Orthopaedics, FuyangHospital of Anhui Medical University, Fuyang, Anhui, China.
Objective: This study aims to elucidate the impact of varying tourniquet application timings on postoperative pain and the bone cement interface following TKA.
Method: Patients who underwent TKA in our department between March 2021 and July 2023 were included in this study. They were randomly assigned to three groups: Group 1 used tourniquets throughout the operation, Group 2 applied tourniquets before the osteotomy, and Group 3 applied tourniquets after completing the osteotomy.
Knee loading and joint pain during daily activities in people with knee osteoarthritis: A systematic review and meta-analysis.
Clin Biomech (Bristol)
January 2025
Department for Health, University of Bath, Bath, UK; Centre for the Analysis of Motion, Entertainment Research and Applications (CAMERA), University of Bath, Bath, UK.
Background: Knee loading is associated with the severity and progression of knee osteoarthritis, while knee pain contributes to reduced functional ability and quality of life. In this systematic review, we quantified knee loading and knee pain during different daily activities in people with knee osteoarthritis and explored methodological reasons for differences between studies.
Methods: PubMed, Web of Science, Scopus, and manual searches were performed up to July 2024, to retrieve studies measuring knee loading and knee pain in walking, sit-to-stand and stair climbing of people with knee osteoarthritis.
Early Identification of Poorly Performing Implants in Michigan With the Example of the Vanguard XP.
Arthroplast Today
December 2024
The CORE Institute, Phoenix, AZ, USA.
Background: Arthroplasty registries play a critical role in improving the quality of care and performing post-market surveillance of medical devices. We report the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) findings specific to the Biomet Vanguard XP bicruciate-retaining total knee implant.
Methods: Data were collected from MARCQI's 2019 report (February 15, 2012, through December 31, 2018).
