Chronic exertional compartment syndrome is an incapacitating condition that primarily affects athletes and individuals with high activity levels. The exact etiology of the condition is unknown to date, but multiple factors play a role in its occurrence. The clinical presentation includes pain, tightness, muscle weakness, paresthesia, and cramps. Common tools utilized during the diagnostic approach include intramuscular compartment pressure measurement, advanced imaging to exclude other disorder entities, near-infrared spectrometry, and shear wave elastography, with the clinical diagnosis being the gold standard...

Acute patellar dislocation (PD) is usually a problem of adolescents and young adults. In most cases, it is a sports-related injury. It is the result of an indirect force on the knee joint, which leads to valgus and external rotation of the tibia relative to the femur. PD is unlikely to occur on a knee with normal patellofemoral joint (PFJ) anatomy. Acute PD consists of an acute injury of the ligamentous medial patellar stabilizers in the background of factors predisposing to patellar instability. These factors are classified into three groups...

Medial meniscal posterior root tears disrupt the "hoop" function of the meniscus and may lead to knee osteoarthritis. Although root repair could be a key to osteoarthritis prevention, this surgery does not necessarily guarantee an optimal result even when combined with meniscal centralization and high tibial osteotomy. To address this issue, we made five modifications to the original combined approach, namely two anchors to fix the root, instead of one; bridging centralization instead of single centralization; release of the meniscotibial capsule vs no release; release of valgus stress before knot tying vs no release; and prohibiting postoperative cross-legged sitting and sitting on heels...

BACKGROUND: At present, not all Type AO/OTA 42A2 open fractures can be treated by external fixation brackets, not to mention the inconvenience of this technique in clinical practice. External titanium alloy locking plates, which are lightweight and easy-to-operate, can be used as an alternative treatment option for such patients. However, there are few reports of finite element biomechanical analysis on the titanium alloy locking plates and fixation brackets being placed on the medial side of the tibial fracture...

A case of anteromedial leg pain diagnosed and treated for 10 years as "shin splints" (medial tibial stress syndrome) is described. A history and examination was performed focused on anatomy, biomechanics, and peripheral nerves. Detailed sensory testing was performed in the painful area, and imaging was obtained to confirm the diagnosis. The clinical investigation was consistent with dynamic stenosis of the left L4-5 intervertebral foramen, causing a mixed partial mononeuropathy of the L4 spinal nerve that presented as pain and hypersensitivity in the anteromedial shin...

Osteoarthritis (OA) is a worldwide joint disease. However, the precise mechanism causing OA remains unclear. Our primary aim was to identify vital biomarkers associated with the mechano-inflammatory aspect of OA, providing potential diagnostic and therapeutic targets for OA. Thirty OA patients who underwent total knee arthroplasty were recruited, and cartilage samples were obtained from both the lateral tibial plateau (LTP) and medial tibial plateau (MTP). GO and KEGG enrichment analyses were performed, and the protein-protein interaction (PPI) assessment was conducted for hub genes...

BACKGROUND: Tibialis posterior tendon, deltoid ligament and spring ligament are the three most important structures on the medial aspect of the foot. They contribute to the stability of the foot and ankle and also to the maintenance of the arches of the foot. These structures get affected and dimensions get disrupted in various traumatic and degenerative conditions. Normal range of dimensions of these structures has not been studied in an Indian population. Our objective is to define the normal thicknesses of these structures using a cadaveric model...

Variation in tibial geometry may alter strain magnitude and distribution during locomotion. We investigated the effect of tibia-fibula geometric variations on tibial strain with running loads applied at various speeds. Participant-specific three-dimensional models of the tibia-fibula were created using lower limb computed tomography scans from 30 cadavers. Finite-element models were developed in FEBio, and running loads from 3, 4 and 5 m s-1 were applied to extract effective strain from the tibial shaft. Linear regression models evaluated the relationship between geometric characteristics and effective strain along the tibial shaft...

INTRODUCTION: Meniscal root tear decreases the ability of the meniscus to convert the axial load to radially directed hoop stress. This leads to a decreased contact area and increased contact pressures, leading to early osteoarthrosis of the knee and eventually higher chances of undergoing total knee replacement. Meniscal root repair helps to restore normal knee kinematics; however, non-anatomical repair results in increased strain in the repair and causes early failure of the repair, leading to abnormal knee kinematics...

BACKGROUND: Posterior medial meniscus root (PMMR) tears have been associated with increased posterior tibial slope, but this has not been fully evaluated biomechanically. In addition, the effects of knee flexion and rotation on the PMMR are not well understood biomechanically because of technological testing limitations. A novel multiaxial force sensor has made it possible to elucidate answers to these questions. PURPOSE: (1) To determine if increased posterior tibial slope results in increased posterior shear force and compression on the PMMR, (2) to evaluate how knee flexion angle affects PMMR forces, and (3) to assess how internal and external rotation affects force at the PMMR...

BACKGROUND: Osteoarthritis (OA) is a degenerative joint disease associated with aging, which often leads to joint stiffness and disability. Exercise is one of the most important non-pharmacological treatments and is prescribed as an indispensable treatment for OA. However, whether physical exercise is beneficial for preventing the progression of OA symptoms with age is poorly understood. We investigated the effects of exercise on spontaneously developed knee OA using male senescence-accelerated mouse prone 8 (SAMP8)...
