44-year-old male that sustained a contusion to his left shoulder while falling at his home. Following the fall he suffered severe pain. An ultrasound to the shoulder was interpreted as showing some changes in the ACJ and peritendinitis of the biceps brachi. The orthopedic surgeon that examined the patient about 2 weeks post injury had the impression of tendinopathy and requested an MRI that had indicated changes in signals in the ACJ and superior impingement of the supraspinatus and peritendinitis of the biceps. On the basis of these findings an arthroscopy was suggested.

25-year-old male suffers from pain in his left knee that shows up after carrying out a limited physical activity. The length and the importance of the pain are proportional to the intensity of the physical activity, the pain is gradual, and is linked to the movement of the knee joint. Knee MRN showed misalignment of the femur and kneecap with the patella, diffuse superficial edema of the kneecap cartilage, and signs of diffuse tendinopathy. In the expert's opinion, the patient suffers from patello-femoral knee pain due to patellar malalignment or patellar maltracking.
