This retrospective study aimed to provide data on the prevalence, epidemiology and etiology of the knee articular cartilage lesions and describe and estimate, on the ground of a large database, the number of patients who might benefit from cartilage repair surgery. The analysis of 25,124 knee arthroscopies performed from 1989 to 2004 was conducted.(More)
BACKGROUND If anterior cruciate ligament (ACL) reconstruction is to be performed, decision regarding graft choice and its fixation remains one of the most controversial. Multiple techniques for ACL reconstruction are available. To avoid disadvantages related to fixation devices, a hardware-free, press-fit ACL reconstruction technique was developed. The aim(More)
BACKGROUND Chondral lesions are often documented at the time of anterior cruciate ligament reconstruction. They are usually asymptomatic. It is not known if these lesions change the outcome of current ACL treatments. HYPOTHESIS Untreated deep cartilage lesions incidentally found during anterior cruciate ligament reconstruction do not affect clinical and(More)
The purpose of this clinical study was to assess low frequency, low intensity magnetic fields in the enhancement of the physical rehabilitation of patients after knee endoprosthesis surgery. The study included 62 patients who underwent total knee arthroplasty. Group A consisted of 32 patients who were physically rehabilitated. Group B consisted of 30(More)
The purpose of this in vitro study was to assess the potential influence of low frequency, low intensity magnetic fields (rectangular pulse, 5 mT, 30 Hz) applied in therapy on the temperature, contact electric potential, and magnetization in knee endoprosthesis, which might be dangerous for implantation and stability of knee prosthesis, and later slacking(More)
PURPOSE OF THE STUDY The aim of this study was to provide data on the prevalence and epidemiology of isolated deep chondral lesions of the knee, diagnosed in arthroscopy. The study was also aimed to analyse subjective treatment results of localized deep isolated cartilage lesions and to determine how the different factors might affect the final outcome.(More)
BACKGROUND The aim of this study was to assess the utility of the Coonrad-Morrey elbow prosthesis in patients with severe elbow dysfunction secondary to rheumatoid arthritis (RA) or post-traumatic elbow dysfunction. MATERIAL/METHODS The study involved 35 patients followed up for a mean of 36 months. The patients were divided into those with RA (Group I)(More)
BACKGROUND Distal radius fractures are a serious clinical problem. The evaluation of fracture stability and selection of a treatment method are of key importance for treatment outcomes. Purpose of the study. The study evaluated the outcomes of treatment of unstable distal radius fractures using percutaneous K wire fixation. MATERIAL AND METHODS A total of(More)
BACKGROUND A common feature of dysplasia fibrosa and defectus fibrosus is the development of foci of disordered fibrous tissue in bone that tend to grow and displace regular bone tissue. The objective of this study was to evaluate the efficacy of surgical treatment with bone allografts in patients with fibrous dysplasia and fibrous defect of bone. (More)
