This study investigated the activity of surface electromyography (sEMG) on trunk and pelvic muscles during supine bridge exercise (SBE) with different knee flexion angles. Twenty-five physically active males participated in this study. Subjects received maximum voluntary isometric contraction (MVIC) tests followed by four SBEs with different knee flexion angles (40°, 60°, 90° and 120°) in random. sEMG activities of rectus abdominis (RA), erector spinae (ER), gluteus medius (GMed), superior gluteus maximus (SGMax), inferior gluteus maximus (IGMax), biceps femoris (BF) long head, and the ratio of SGMax/BF and IGMax/BF on the dominant side were measured. Non-clinical magnitude-based inference was performed to compare the effect. The results indicated a substantial change of muscle activity, especially between SBE with 40° and 120° knee flexion. With respect to ER and BF, moderate effect (-0.70 ± 0.17) and extremely large effect (-4.78 ± 0.51) were recorded, whereas very large effect for SGMax/BF (2.68 ± 0.23) and IGMax/BF (2.95 ± 0.26) was observed, respectively. Both ER and BF worked better with smaller knee flexion angles (40° > 60° > 90° > 120°), while SGMax and IGMax were more favourable to SBE with large knee flexion angles (90° = 120° > 60° > 40°).

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).
Acute effects of tissue flossing on boxers with chronic knee pain.
Front Bioeng Biotechnol

School of Athletic Performance, Shanghai University of Sport, Shanghai, China.
Objectives: To explore the acute intervention effects of tissue flossing on chronic knee pain (CKP) in boxers.
Methods: Eighteen boxers with CKP (12 male/6 female) were randomly divided into an experimental group (EG) with tissue flossing (n = 9) and a control group (CG) (n = 9). The visual analog scale (VAS), Lysholm knee function score, flexion range of motion (ROM), maximal isometric extensor muscle strength, and stability of the knee were measured pre- and post-intervention (EG: 3-minute tissue flossing, CG: rest).
Simultaneous total hip and knee arthroplasties in hemophilic arthropathy: series of 5 cases.
Acta Orthop Traumatol Turc
December 2024
Department of Orthopedics and Traumatology, Ege University School of Medicine, Izmir, Türkiye.
Objective: This study aimed to compare preoperative and postoperative measures in haemophiliacs who had simultaneous total hip and knee arthroplasties.
Methods: A retrospective database search identified five patients with severe factor 8 deficiencies who underwent simultaneous hip and knee joint replacement surgery between 2002-2018. Preoperative and postoperative evaluations included Harris Hip Score (HHS), Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), range of motion, flexion contracture (FC), Visual Analog Scale (VAS), hip-knee angle, and leg length discrepancy.
Impact of exercise with blood flow restriction on muscle hypertrophy and performance outcomes in men and women.
PLoS One

Cardiometabolic, Exercise, and Lifestyle Laboratory, University of New Brunswick, Fredericton, NB, Canada.
Blood flow restriction training (BFRT) has been previously studied as an alternative form of resistance training to gain lean mass and improve performance outcomes. However, in all exercise studies of BFRT, the proportion of female participants represents only 17-29% of all research participants. This highlights a strong underrepresentation of females and the need for more knowledge on the impact of BFRT and sex differences.

Purpose: This study reports the relationship between posterior cruciate ligament (PCL) retention vs resection and soft tissue laxity and balance throughout flexion using a robotically controlled ligament tensioner.
Methods: 55 robotic-assisted TKAs (Total knee arthroplasty) were retrospectively reviewe. The robotic ligament tensioner collected laxity data both before and after PCL resection.
