PURPOSE Recently, new custom-fit pin guides in total knee arthroplasty (TKA) have been introduced. Use of these guides may reduce operating time. Use of the guides combined with the absence of intramedullary alignment jigs may lead to reduced blood loss and improved early outcomes. Our aim was to evaluate blood loss and early clinical outcomes in patients(More)
PURPOSE To determine the accuracy of magnetic resonance (MR) imaging and MR arthrography in the detection and staging of lesions of the acetabular labrum. MATERIALS AND METHODS Fifty-seven hips of 56 patients with chronic hip pain and a strong clinical suspicion of labral lesions were examined with a three-dimensional gradient-echo sequence in the coronal(More)
OBJECTIVE Our purpose was to describe the appearance of the acetabular capsular-labral complex on MR arthrography and to correlate this appearance with surgical findings in adult patients and with gross anatomic findings in cadavers. SUBJECTS AND METHODS MR arthrography of the hip joint was performed in 40 patients and six cadavers. All patients underwent(More)
To assess of the value of conservative and operative treatment of osteochondritis dissecans of the knee, a multicenter study was performed. In 12 European countries, 798 cases of osteochondritis of the knee have been collected from 44 hospitals. Results were based on 452 patients with 509 affected knees with minimum follow-up was 1 year (mean follow-up, 3(More)
The capsular-labrum-complex consists of the triangular fibrocartilaginous labrum, which is fixed at the bony acetabular ring and supported by the ligamentum transversum actetabuli in the caudal part. In a normally developed and correctly orientated acetabulum, the femoral head is symmetrically covered by the contact area of the lunate surface. The vertical(More)
Changes or limitations of the rotational range of motion of the hip are a non-specific clinical sign. There is a big variety of underlying morphological pathologies resulting in a symptomatic alteration of hip rotation. They need to be assessed by imaging techniques: based on plain radiographs (including specialized projections), often CT or MRI are(More)
Effective prevention of late dysplastic dislocation of the hip (DDH) has become a reality since reliable diagnosis has been possible at an early stage by means of the original sonographic method according to Graf. A correct sonographic diagnosis must be instantly followed by adequate, biomechanically rational, and consistent therapeutic management and(More)
We compared two similarly sized groups of sonographically unstable or decentered hips with comparable initial findings, both treated by standardized conservative primary treatment. The results show that an early definite diagnosis improves the prognosis. If built on a secure initial diagnosis rationally grounded and efficient conservative therapy can be(More)
Labral lesions are a sign of biomechanical decompensation of the hip joint and often represent the first clinical symptom of residual hip dysplasia (RHD) in the adult. Provocation tests (impingement, apprehension) are typical but not specific. Labral lesions and concomitant findings (intra- and extraosseous ganglia, stress bone marrow oedema) can be(More)
