The current study is aimed at examining the validity of five clinical patellofemoral tests used in the diagnosis of patellofemoral pain syndrome (PFPS). Forty-five knee patients were divided into either the PFPS or the non-PFPS group, based on the fulfilment of the diagnostic criteria for PFPS. An investigator, blinded to the group assignment, performed the vastus medialis coordination test, patellar apprehension test, Waldron's test, Clarke's test, and the eccentric step test. The positive likelihood ratio was 2.26 for both the vastus medialis coordination test and the patellar apprehension test. For the eccentric step test, the positive likelihood ratio was 2.34. A positive outcome on either the vastus medialis coordination test, the patellar apprehension test, or the eccentric step test increases the probability of PFPS to a small, but sometimes important, degree. For the remaining tests, the positive likelihood ratios were below the threshold value of 2, indicating that given a positive test result, the probability that the patient has PFPS is altered to a small, and rarely important degree. The negative likelihood ratios for all tests exceeded the threshold value of 0.5, suggestive of clinically irrelevant information. These data question the validity of clinical tests for the diagnosis of PFPS.

Purpose The infrapatellar fat pad (IFP) has the lowest pain threshold among all knee joint components and causes anterior knee pain after knee arthroplasty. It has been reported that selective muscle atrophy of the vastus medialis (VM) and fibrosis of the IFP may develop following knee joint surgery. Ultrasound enables visualization of IFP deformation (A1) from within the joint to the proximal area in response to muscle contraction, and this may be helpful in developing preventive and therapeutic strategies for IFP fibrosis.

Background: There has been increased interest in lateral extra-articular procedures, such as anterolateral ligament reconstruction (ALLR) or lateral extra-articular tenodesis (LET), to reduce anterolateral rotation instability of the knee after anterior cruciate ligament reconstruction (ACLR). Despite promising surgical outcomes with these techniques, their impact on knee strength recovery is unknown.
Hypothesis: Patients undergoing lateral extra-articular procedures at the time of ACLR would have impaired thigh muscle strength at 6 to 9 months after surgery.

Objective: In this study, we aimed to determine the effects of 2-week neuromuscular electrical stimulation (NMES) on quadriceps muscle atrophy and lower extremity motor score in individuals with subacute incomplete cervical spinal cord injury (SCI).
Methods: This stratified randomized controlled trial, conducted in the advanced critical care center of a university hospital, comprised 49 individuals with American Spinal Injury Association (ASIA) impairment scale grade C and D incomplete cervical SCI. The participants were stratified based on the ASIA impairment scale grade and randomly assigned to the control (n = 25) or NMES (n = 24) group.

Introduction: More extensive and cohesive studies on quadriceps tendon rupture (QTR) repair surgery are required to guide effective treatment strategies. Therefore, in this study, we aimed to identify predictors of subjective functional recovery following QTR repair surgery.
Materials And Methods: This multicentre retrospective cohort study enrolled 191 adults (age ≥ 18 years) who underwent surgical unilateral QTR repair (2010-2022) and had ≥ 1-year postoperative follow-up at three trauma centres in Germany.

Background: This is a novel rat study using native peptide therapy, focused on reversing quadriceps muscle-to-bone detachment to reattachment and stable gastric pentadecapeptide BPC 157 per-oral therapy for shared muscle healing and function restoration.
Methods: Pharmacotherapy recovering various muscle, tendon, ligament, and bone lesions, and severed junctions (i.e.
