Pezcyclingnews: Toolbox: Cycling Knee Pain


Jan 3, 2005
One of the most common overuse bicycling injuries involves the knee. Chondromalacia patella, patellar and quadriceps tendinitis and patellofemoral pain syndrome are common diagnoses of anterior knee in competitive cyclists.The high incidence of knee injuries in bicycling is not surprising given the biomechanics of force exertion through the lower extremities. It has been reported that knee and back injuries together caused 73.9% of overuse injuries resulting in time loss from training and competition. The knees extensor mechanism is comprised of the quadriceps muscle, the quadriceps tendon at the top of the patella, the patella and the patellar tendon at the bottom of the patella. The different parts of the extensor mechanism, individually or in combination, are susceptible to injury in bicycling.CategorizationsMany labels are use to describe specific types of tendon injuries or tendinopathies, including tendinitis, tenosynovitis and tendinosis. Tendinitis is used to describe an acute tendon injury, ranging between 0 to 6 weeks, during which time there are is an active inflammatory response and increased vascularity which leading to symptoms of pain, swelling, redness and warmth. As tendon injuries become more chronic, there is an accumulation of non-inflammatory tendon degeneration and damage, leading to the description of tendinosis. Bicyclists are susceptible to both types of tendon injury in the quadriceps and patellar tendon. Chondromalacia patella (CP) refers to degeneration and damage of the articular cartilage covering the underside of the patella. The degree of CP can vary from mild softening of the cartilage to complete loss of articular cartilage and...
