Running can be viewed as a series of collisions with the ground and the knee is the most biomechanics of running pdf injury site. The Effects of Running on Menisci and Articular Cartilage Running is currently one of the most popular sports activities. Nevertheless, the question often arises as to whether the high levels of joint loading involved in running have negative effects.
The following study was undertaken to examine the rate of recovery from alterations occurring at the knee joint in marathon runners due to loading. After the 20-km run, there was a significant transient decrease in cartilage volume.

Running Injuries to the Knee Distance running is a significant part of the basic fitness program of many people. Approximately one third of serious runners will incur an injury in a given year, and approximately one third of the injuries will involve the knee. In patients with iliotibial band syndrome, MRI is very useful diagnostically and shows a thickened iliotibial band over the lateral femoral epicondyle. This overuse injury occurs with repetitive flexion and extension of the knee. Inflammation and irritation of the iliotibial band also may occur because of a lack of flexibility of the ITB, which can result in an increase in tension on the ITB during the stance phase of running. Other causes or factors that are believed to predispose an athlete to ITBS include excessive internal tibial rotation, genu varum, and increased pronation of the foot. The main symptom of ITBS is sharp pain or burning on the lateral aspect of the knee.
Runners often note that they start out running pain free but develop symptoms after a reproducible time or distance. Early on, symptoms subside shortly after a run, but return with the next run. If ITBS progresses, pain can persist even during walking, particularly when the patient ascends or descends stairs. Low mileage, recreational runners usually improve with a simple regimen of anti-inflammatory medication and appropriate stretches. However, higher mileage, competitive runners typically require a more comprehensive treatment approach. Treating the condition can be a challenge because underlying myofascial restrictions can significantly contribute to the patient’s pain and disability.

Although the surgical treatment of patellar tendinopathy is a common procedure, there have been no randomized, controlled trials comparing this treatment with forms of non-operative treatment. The purpose of the study conducted by Roald Bahr and colaborators was to compare the outcome of open patellar tenotomy with that of eccentric strength training in patients with patellar tendinopathy. Eccentric exercises: “the key to the rationale behind eccentric drills is that they are the best way of promoting tendon remodelling – the regrowth and reordering of fibrous tissue in place of the denser, degenerative tissue typical of tendinosis. There will be some days when the athlete can manage more repetitions than others, but normally they will be able to move on to the next stage after 2 to 4 weeks — so improvement in this condition is usually measured in months, not weeks. Patellar tendinitis: why patellar tendinitis is usually the wrong diagnosis for patellar tendon pain, and how to banish patellar tendon pain?

Other Running Injuries We do knees only and therefore this page focuses on running knee injuries. Selecting Running Shoes There is no single best running shoe as everyone has different needs. Your biomechanics and gait patterns, the size and the shape of your feet, your weight and the surfaces you run on all play an important role in selecting the best possible running shoes. Do you overpronate, underpronate or have a neutral landing? Will you use shoes for trail running, competition, or just general fitness?
