Tennis and golf elbow

“Tennis and golfer’s elbow” are common pathologies due to overload of forearm extensors and flexors, and actually occur mostly outside tennis and golf sports. Several differential diagnoses of medial and lateral epicondylitis have to be excluded as there are a number of other conditions with similar clinical symptoms. The high rate of spontaneous recovery has to be considered in treatment. Evidence based conservative treatment comprises excentric physiotherapy, local injections, and physical methods. Surgery is reserved for patients with persistence of symptoms for more than one year despite non-surgical treatment.

Tendon problems around the knee

The knee joint is affected in up to 30% of all sport injuries. A minor precentage of it are tendon injuries. For acute tendon injuries, quadriceps tendon rupture and patellar tendon rupture are most frequent. Beside that, ruptures of distal hamstring tendons or the popliteus tendon may occur. For chronic tendon injuries in sports, the jumpers knee and the runners knee are most frequent. Also insertional enthesopathy of the quadriceps tendon, of the iliotibial band, of the hamstring tendons may occur, furthermore a tendinitis or bursitis at the pes anserinus. These injuries are explained in this article focussing on symptoms, diagnostics and therapy.

Rare tendon pathologies at the foot level

While lesions of the achilles tendon and posterior tibial tendon are common and well known, lesions of other ankle bridging tendons are rare and literature is sparse. However, many of these lesions are equally relevant in terms of maintaining the complex functionality of the foot. Such pathologies include tendinitis, tenosynovitis as well as partial and complete tears. If the continuity of the affected tendon is maintained, conservative treatment is appropriate. In cases of ruptures, operative therapy is often needed. Depending on the defect size and retraction of the tendon, auto- or allograft have to be used.

Tendons – Morphology, biology and biomechanics

The tendon has to be seen functionally within the muscle-tendon-unit. The tendon has to transmit the force that is produced by the muscle, but acts also as a spring that stores energy. The tendon itself consists of three parts: the tendon-bone insertion, the mid-portion area, and the muscle-tendon junction. The biomechanical properties belong primarily on type I collagen, that degenerates in case of tendinopathy.

High relevance of difference in trail characteristics for average running times in orienteering

Background Orienteering takes place in a range of different areas including mountains and woodlands, whereby motoric and coordinative requirements on the orienteers differ strongly de­pending on the respective terrain. The aim of this study was to investigate differences in average speed of orienteers in three terrain types in Switzerland: Alps, Jura and Mittelland.
