BACKGROUND Tegner and Lysholm described their generally acknowledged activity score in 1985. It was originally tested for knee ligament injuries, but for the past 17 years it has been used for other joint evaluations as well. The development of already existing and new kinds of sports, differences between knee and ankle loading, and different injury rates(More)
BACKGROUND Several methods are used to treat focal chondral and osteochondral defects on the weightbearing surfaces of synovial joints. Autologous osteochondral grafting is 1 option used to replace hyaline cartilage in the defect. HYPOTHESIS Mosaicplasty is effective in returning elite athletes to participation in sports. STUDY DESIGN Case series; Level(More)
BACKGROUND A search of the literature shows that the effect of surgery on ankle proprioception has been hardly investigated. OBJECTIVE To examine the effect of anatomical reconstruction of the anterolateral capsuloligamentous complex on ankle joint position sense. METHODS A prospective study using the "slope box" test. Ten consecutive patients were(More)
In this experimental study, the authors evaluated the biomechanical properties of the femoral press-fit graft fixation technique in ACL reconstruction. 20 fresh frozen distal femurs, patellae and patellar ligaments were used from 10 cadaver specimens. Three bone-patellar tendon grafts of 10 mm width were prepared from each sample; altogether 60(More)
Improvement of ankle proprioception through physiotherapy (a.k.a. proprioceptive training) is a widely accepted conservative treatment modality of chronic functional lateral ankle instability. Clinical studies provided controversial data on its proprioceptive effect. Aim of this study was to gain evidence on the efficacy of proprioceptive training on ankle(More)
One hundred and fifty six patients were treated using the modified double suture technique for percutaneous Achilles tendon repair between 1994 and 1998. Endoscopy was used in 67 cases. The first ten cases were dropped (learning curve), 57 were followed (E-group). Percutaneous suture without endoscopy was performed in 89 patients. Two could not be followed(More)
BACKGROUND A number of studies have shown that proprioception training can reduce the risk of injuries in pivoting sports, but the mechanism is not clearly understood. AIM To determine the contributing effects of propioception on knee joint position sense among team handball players. STUDY DESIGN Prospective cohort study. METHODS Two professional(More)
BACKGROUND The security of the graft fixation is an important factor of anterior cruciate ligament reconstruction, especially in the early postoperative period. HYPOTHESIS The femoral press-fit fixation technique is a safe, alternative technique for the fixation of the bone-patellar tendon-bone graft. STUDY DESIGN Case series; Level of evidence, 4. (More)
BACKGROUND In normal conditions, proteins are not present in the urine, however, exercise of long duration could result in proteinurea. Increased levels of reactive oxygen and nitrogen species (RONS) are formed during exhaustive physical exercise and causes alterations to cellular proteins. MATERIALS In the present study serum and urinary nitrotyrosine(More)
