[Treatment of deep cartilage defects of the knee with autologous chondrocyte transplantation on a hyaluronic Acid ester scaffolds (Hyalograft C)].
The treatment of chondral defects by transplantation of autologous chondrocytes has recently shown further development. Various biomaterials are used as carriers facilitating attachment and even distribution of chondrocytes in the defect. Since 2003 Hyalograft C, hyaluronan-based scaffolds, has been used, in a clinical study, for implantation of autologous chondrocytes in the treatment of deep chondral lesions of the knee at our department. ⋯ Based on our results we suggest that the use of Hyalograft C is a safe and effective option for treatment of deep chondral defects of the knee; it is particularly useful in patients in whom the primary defect treatment has failed. The application of Haylograft C is relatively quick and easy; this is convenient when surgery involves more than one procedure (ligament reconstruction, osteotomy). However, a definite evaluation of this method will be possible only after long-term results are available. Key words: deep cartilage defects, chondral defects, cartilage repair, autologous chondrocyte transplantation, hyaluronan- based scaffold, Hyalograft C, cartilage repair assessment, ICRS.

[Hip joint arthroplasty following surgical treatment of acetabular fracture].
A group of 49 patients treated by total hip arthroplasty after previous surgery for an acetabular fracture are evaluated in this retrospective study. ⋯ Total hip arthroplasty carried out after acetabular fracture is technically demanding. The prerequisite for a good result is to achieve primary stability of the acetabulum. Acetabular reconstruction is based, in the first place, on replacement of the missing bony tissue, and on providing conditions for correct alignment of the acetabulum and reliable primary and early secondary osteointegration. THA after acetabular fracture achieves poorer results than when it is indicated for degenerative disease. Key words: acetabular fracture, post-traumatic hip arthritis, total hip replacement.

[Early primary total hip arthroplasty for acetabular fractures in elderly patients].
The aim of this pilot study was to evaluate the clinical and functional outcomes of total hip arthroplasty (THA) in patients with acetabular fractures due to a low-energy injury. Acute primary THA included an antiprotrusion cage and autologous bone grafting of the acetabulum. This prospective study was carried out between 1998 and 2004. ⋯ Acute primary THA with the use of a antiprotrusion cage and bone grafting for acetabular fractures in elderly patients allows us to employ only one surgical technique for definitive repair. It provides primary stability and immediate pain relief, permits graded weight-bearing and early pain-free mobilization, and may also treat hip arthritis, if it exists. This technique has also good prospects for a selected group of younger patients in whom the treatment of acetabular fractures has a poor prognosis. Key words: acetabular fracture, elderly patient, primary total hip arthroplasty.
