Autologous chondrocyte implantation (ACI) is used widely as a treatment for symptomatic chondral and osteochondral defects of the knee. Variations of the original periosteum-cover technique include the use of porcine-derived type I/type III collagen as a cover (ACI-C) and matrix-induced autologous chondrocyte implantation (MACI) using a collagen bilayer(More)
We treated 98 patients with peri-acetabular tumours by resection and reconstruction with a custom-made pelvic endoprosthesis. The overall survival of the patients was 67% at five years, 54% at ten years and 51% at 30 years. One or more complications occurred in 58.1% of patients (54), of which infection was the most common, affecting 30% (28 patients). The(More)
UNLABELLED Autologous chondrocyte implantation is a new technique for the treatment of chondral defects in the knee. The exact procedure involved is continuously being developed with the ultimate aim of achieving hyaline cartilage regeneration. We present the outcome of our series of 31 patients, focussing on the use of the chondrogide membrane in the(More)
We prospectively studied the clinical, arthroscopic and histological results of collagen-covered autologous chondrocyte implantation (ACI-C) in patients with symptomatic osteochondritis dissecans of the knee. The study included 37 patients who were evaluated at a mean follow-up of 4.08 years. Clinical results showed a mean improvement in the modified(More)
The distal radius and its articulations clearly have a vital role in the functional abilities of the hand and wrist. The treatment of tumours of the radius, therefore, needs to achieve satisfactory clearance of the lesions while also preserving as much wrist function as possible. We have employed osteoarticular autologous fibula grafts to reconstitute the(More)
AIM To describe the preoperative magnetic resonance imaging findings of eight histologically-proven cases of hibernoma. MATERIALS AND METHODS The site, size, and signal characteristics of eight consecutive hibernomas were retrospectively assessed on T1-weighted spin-echo and short T1 inversion recovery (STIR)/fat-saturated T2-weighted fast spin echo(More)
BACKGROUND Different treatment strategies for low-grade chondrosarcomas are reported in the literature with variable outcomes. The aim of this study was to assess the oncological and functional outcomes associated with intralesional curettage and cementation of the lesion as a treatment strategy. PATIENTS AND METHODS We performed a retrospective review of(More)
We assessed the reproducibility and accuracy of four ratios used to measure patellar height, namely the Blackburne-Peel, Caton-Deschamps, Insall-Salvati and modified Insall-Salvati, before and after total knee arthroplasty. The patellar height was measured, by means of the four ratios, on the pre- and post-operative lateral radiographs of 44 patients (45(More)
STUDY DESIGN Case report. OBJECTIVES To report a rare case of spinal cord infarction following therapeutic computed tomography-guided nerve root injection. SUMMARY OF BACKGROUND DATA Diagnostic and therapeutic image-guided nerve root injection is commonly performed in the management of low back pain and sciatica. The severe complication of spinal cord(More)
PURPOSE To examine the feasibility, tolerability, and toxicity of an intensified induction regimen (vincristine, ifosfamide, doxorubicin, and etoposide [VIDE]) in patients with newly diagnosed Ewing's family of tumors (EFT); to assess ability to maintain dose-intensity, and predictability of peripheral-blood stem cell mobilization.
