Pain and discomfort in the knee joint are common reasons for consultations in daily routine. The reasons are diverse and can be of traumatic or chronic origin. Identifying the reason for knee pain may be challenging. Using a “knee-map” may help to diagnose possible pathologies. Consequently, treatment depends on the final diagnosis. When a traumatic effusion is present, a relevant intra-articular damage should be considered.

“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.

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.

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.

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.

The purpose of this study was to retrospectively evaluate the effectiveness of Platelet-Rich Plasma Injection (PRP) for Achilles and patellar tendinopathy refractory to conventional conservative treatments. For this, we compared the data from 34 patients treated with one or two injections of PRP. Pain, functional ability, athletic recovery and satisfaction of patients were evaluated.

Objective. Sports injuries are one of the most common injuries in the modern Western society. In line with the increased interest in eHealth, a tailor-based online injury prevention intervention was developed to influence determinants and actual sports injury preventive behaviour. An effect study was carried out among runners. Methods. Runners between 18 and 35 years were randomly assigned to the intervention (n=109) or control group (n=105). Participants in the intervention group were invited to visit the website for 30 minutes. Those in the control group were invited to read magazines that did not contain information about running, injuries or other sport related issues for 30 minutes.
