Case ReportsRehabilitation of avulsion fracture of the tibial tuberosity following Osgood-Schlatter disease.
A sixteen-year-old boy suffered from sharp pain in the knee during a jump while playing basketball. He had a positive history of Osgood Schlatter disease. Radiographic evaluation demonstrated an avulsion fracture of the tibial tuberosity Type III according to the classification of Watson-Jones. ⋯ In such avulsion fractures, landing on the ground with the knee fully extended after a jump is the most likely cause. This case report reviews the rehabilitation program, and selected functional outcome measures after rehabilitation are reported. The patient returned to sporting activity after 12 months.

Clinical TrialDiagnosis of chondral lesions of the knee joint: can MRI replace arthroscopy? A prospective study.
The role of magnetic resonance tomography (MRI) for the diagnosis of chondral lesions of the knee joint is still unclear. The sensitivity of the method ranges from 15% to 96%. The scope of our daily experiences showed that there were considerable deviations between the tomographical and arthroscopical results, which vary from the results of experimental studies. ⋯ In view of the high specificity (97%-99%) and the high negative prediction value (97%-98%), MRI is suitable for the exclusion of cartilage lesions. For a negative MRI associated with a cartilage injury, a cautious attitude towards an operative cartilage treatment is therefore justified. Because the MRI can not replace the ASC for diagnostic of cartilage damage, the ASC still has to be seen as the method of choice for the evaluation of cartilage damage.

Case ReportsIsolated complete popliteal artery rupture associated with knee dislocation. Case reports.
Complete dislocation of the knee is a rare injury, and is frequently associated with injuries to other structures in the popliteal fossa. Prompt recognition of associated popliteal artery disruption and early revascularization is paramount for successful and functional results. The necessity for emergency vascular reconstruction markedly complicates an already difficult orthopaedic problem. Arteriography is recommended in all cases of complete dislocation of the knee.

Variations in anatomy at the suprascapular notch possibly causing suprascapular nerve entrapment: an anatomical study.
The purpose of the study was to determine anatomical variations at the suprascapular notch for better understanding of possible predisposing factors for suprascapular nerve entrapment. We dissected 32 shoulders of 16 cadavers between the ages of 39 and 74 years. We observed abnormally oriented superior fibers of the subscapularis muscle in five shoulders of the 16 cadavers, which were covering the entire anterior surface of the suprascapular notch and significantly reducing the available space for the suprascapular nerve. ⋯ In this study, we classified the variations for the superior transverse scapular ligament. In conclusion, knowing the anatomical variations in detail along the course of the suprascapular nerve might be important for better understanding of location and source of the entrapment syndrome, especially for individuals who are involved in violent overhead sports activities such as volleyball and baseball. To our knowledge, close relationship of subscapularis muscle with the suprascapular nerve as a possible risk factor for suprascapular nerve entrapment has not been mentioned previously.

Comparative StudyChronic Achilles tendon pain treated with eccentric calf-muscle training.
Injuries involving the Achilles tendon and manifested as chronic tendon pain are common, especially among recreational athletes. In a pilot study on a small group of patients with chronic painful mid-portion Achilles tendinosis, eccentric calf-muscle training was shown to give good clinical results. The aim of this prospective study was to investigate if the previously achieved good clinical results could be reproduced in a larger group of patients, and also to investigate the effects of eccentric calf-muscle training in patients with chronic insertional Achilles tendon pain. ⋯ In these patients, the amount of pain during activity, registered on the VAS-scale (mean+/-SD), decreased significantly from 66.8+/-19.4 to 10.2+/-13.7. On the contrary, in only ten of the tendons (32%) with chronic insertional Achilles tendon pain was treatment satisfactory, with a significant decrease on the VAS-scale (mean+/-SD), from 68.3+/-7.0 to 13.3+/-13.2. Our conclusion is that treatment with eccentric calf-muscle training produced good clinical results in patients with chronic painful mid-portion Achilles tendinosis, but not in patients with chronic insertional Achilles tendon pain.
