Failed reconstruction of the anterior cruciate ligament (ACL) in a young, active patient represents a difficult clinical problem. Numerous factors contribute to failure, including repeat trauma, technical errors, biologic influences, or a combination of causes. Technical errors commonly include femoral and tibial tunnel malposition, inadequate graft fixation, failure to address associated poste...

High tibial osteotomy (HTO) has traditionally been performed to correct the mechanical axis of the knee in patients with osteoarthritis (OA) of the medial compartment associated with pain and functional impairment; in these patients the restoration of the alignment was related to the regeneration of the articular cartilage that seemed apparently normal (Fujisawa et al., 1979; Odenbring et al., ...

Although total knee arthroplasty is a successful and cost-effective procedure, patient dissatisfaction remains as high as 50%. Postoperative residual knee pain after total knee arthroplasty, with or without crepitation, is a major factor that contributes to patient dissatisfaction. The most common location for residual pain after total knee arthroplasty is anteriorly. Because residual pain has ...

OBJECTIVE To describe the associations between physical disability measures and knee cartilage defects in obese adults. METHODS One hundred and eleven obese subjects were recruited from laparoscopic adjustable gastric banding or exercise/diet weight loss programmes. All subjects completed disease-specific (WOMAC) and general health status (SF-36) questionnaires, and were assessed for range of...

The orthopaedic surgeon who performs opening-wedge high tibial osteotomy (HTO) has to be aware of the behavior slope depending on variations in location hinge and inclination osteotomy. most important point is that changing both rotation axis cut affects slope. There a natural trend unintentionally increase when performing an HTO. However, increased been established as risk factor for primary r...

background: proper rotation of components in total knee arthroplasty (tka) will largely affect the postoperative outcome. ethnical variation may affect rotational profile. we aimed to evaluate distal femur rotation in iranian population using transepicondylar axes.   methods : from a total of 450 knee ct scans and via consecutive sampling, 150 qualified subjects with normal lower extremities al...

The rotational alignment tヲfthe lovver limbs of 24 patients who developed r巴currentdislocation of the patella were measured by means of computed axial tomography. The femoral anteversion and the external rotation of the knee joint of these patients respectively showed 31.9土15.2° and 9.2土6.8° on the average. These figures were significantly larger than those of the control. The average external ...

BACKGROUND AND PURPOSE During the past decades, treatment of pediatric femoral fractures in Finland has changed from mostly non-operative to more operative. In this retrospective study, we analyzed the long-term results of treatment. PATIENTS AND METHODS 74 patients (mean age 7 (0-14) years) with a femoral fracture were treated in Aurora City Hospital in Helsinki during the period 1980-89. 52...

OBJECTIVE To assess factors related to standing balance in patients with knee osteoarthritis (OA). METHODS In total, 37 female patients with painful knee OA were included. Pain, knee alignment, and Kellgren and Lawrence grade were evaluated accordingly. Static standing balance was measured with a force-platform system under two different conditions: static standing with eyes open (EO) and eye...
