   Impact of Running on the Risk and Progression of Knee Osteoarthritis: A Review of Current Evidence.

   Cureus (Glinski et al.)Published Jul 10, 2026Checked Oct 4, 2026

   “This review evaluates the safety of recreational running for knee health, defining the "biomechanical window" based on the latest evidence (2020-2024). The available evidence reveals a U-shaped risk curve, indicating that moderate recreational running is highly protective against knee osteoarthritis (KOA) compared with both sedentary lifestyles and elite, high-volume running. In patients over 50 years of age with existing OA, running does not accelerate structural damage and effectively reduces pain when managed through gradual load progression (the "10% rule"). Recreational running is a safe, chondroprotective intervention. Clinical guidelines should favour individualized load titration over the unfounded discouragement of activity.”

   Common Risk Factors for Knee Injuries in Runners: A Systematic Review.

   Orthopaedic journal of sports medicine (Senthil et al.)Published May 27, 2026Checked Oct 4, 2026

   “For general knee injuries, previous injury was the most frequently reported risk factor, associated with a 12.9% higher incidence of reinjury. PFPS was linked to training load and structural malalignment, indicating small to moderate associations between deviations from optimal load and injury risk. For ITBS, kinematic variables (OR range, 3.02-5.62; Cohen's d range, 1.24-2.21) and kinetic variables (OR, 8.88; Cohen's d, 0.82) were most commonly reported, reflecting moderate to very large effects linked to abnormal pelvic motion and impaired shock absorption. For PT, increased training load and volume (OR range, 1.27-8.94) and demographic factors (OR range, 1.06-1.43) were most frequently reported, with runners training >20 hours per week demonstrating a 15% to 20% higher injury incidence.ConclusionKnee injuries in endurance runners are influenced by a history of injury, training load, and biomechanical factors. Future injury prevention strategies should integrate biomechanical and contextual factors, including individualized kinematic profiles and conservative training management.”

   Running-Related Musculoskeletal Injuries in Saudi Arabia: Epidemiology, Biomechanical Determinants, and Global Comparative Insights.

   Healthcare (Basel, Switzerland) (Aljohani)Published Sep 1, 2026Checked Oct 4, 2026

   “Global evidence indicates that running-related injuries reflect complex interactions among training load, biomechanics, tissue capacity, and environmental factors. Injury prevalence and incidence vary considerably across studies because of methodological heterogeneity, although novice runners generally experience greater injury risk and the knee, lower leg, ankle, and foot are frequently affected. Saudi runner-specific evidence remains limited, with much of the available regional literature derived from cross-sectional, self-reported, or broader physically active populations. In Saudi Arabia, runner-specific injury data remain limited. Existing studies mainly concentrate on general physically active populations and lack standardized injury definitions, exposure-adjusted incidence measures, and prospective designs. Future research should prioritize prospective biomechanical surveillance using wearable sensor technology to capture real-world running mechanics and training loads.”

   Iliotibial band syndrome (Wikipedia)

   WikipediaPublished Sep 29, 2026Checked Oct 4, 2026

   “Iliotibial band syndrome (ITBS), also known as windshield wiper syndrome or runner's knee, is the second most common knee injury. It is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. Risk factors in women include increased hip adduction and knee internal rotation. Risk factors seen in men are increased hip internal rotation and knee adduction. ITB syndrome is most associated with long-distance running, cycling, weight-lifting, and with military training.”
