Abstract:
Vascular collagen prosthesis of RaK type (collagen-impregnated knitted prosthesis) made by Výzkumný ústav pletarský (Research Institute of Hosiery) in Brno was introduced into clinical practice in 1990. In comparison with previous type, the collagen-impregnated prosthesis has had a number of advantages and thus it gets into the interests of vascular surgeons. The report presented has given the results of clinical evaluating study carried out at the IInd Clinic of Surgery, Faculty of Medicine, Masaryk University, Brno according to the methods of EN 540 European Norm Proposal for clinical studies. The results obtained from evaluating a set of 107 patients created for this study (besides others, long-term patency of 90.7%, or 0.9% incidence of infection of the vascular prosthesis of Szilagyi III type) have shown that nowadays we have at disposal a very good, reliable and economically acceptable vascular prosthesis of our provenience.Keywords:

Objective To evaluate the curative effect of two-stage revision of the hip joint for the treatment of elderly postoperative infection after hip arthroplasty. Methods A group of 11 patients(11 hips)above 75 years old with infections after hip arthroplasty admitted in our hospital between January 2001 and June 2008 were studied retrospectively about the clinical manifestation,treatment methods(removal of prosthesis spacer implanted during debridement in the first stage and revision of hip joint in the second stage),postoperative treatment and clinical effects. Results In the 9～42 months(average 18.5 months)′ postoperative follow-up,the mean Harris score increased significantly by 37.0,which was significantly different from preoperative score(P0.05).Infection occurred again in 1 case at the 9th month postoperatively,who was treated with Girdlestone arthrodesis at last. Conclusion Two-stage revision of the hip joint for the treatment of elderly postoperative infection after hip arthroplasty can achieve good results.

One hundred thirty-seven consecutive posterior stabilized total knee arthroplasties (TKAs) were reviewed. Average age of the patient was 61.1 years and length of postoperative follow-up period was 29.2 months. Patients were evaluated using the Hospital for Special Surgery (HSS) knee rating scores. Average preoperative scores improved from 52 to 92, postoperatively. Ninety-eight percent of patients had no pain or mild occasional pain postoperatively compared with 99% of patients experiencing severe to disabling pain preoperatively. Complications included one myocardial infarction, two deep venous thrombosis, one urinary tract infection, one patellar dislocation, and four wound problems. There were wo incidences of seroma, one hematoma, and one deep infection requiring revision after joint debridement and systemic antibiotics. Also noted was one incidence of ligamen-tous laxity and one patella fracture.

Review of 185 consecutive Muller total hip arthroplasties five to nine years after operation showed that 14 patients had died and that three deaths were directly related to the surgery. Of these, 37 patients (54 hips) could not be located and were excluded. Another patient, nonambulatory for an unrelated cause, was also excluded. A total of 126 hips in 104 patients were available for clinical and roentgenographic examinations with a minimal follow-up of five years. The final result was excellent in 70%, good in 10%, fair in 5%, and poor in 15%. One deep infection required removal of the prosthesis. There was no sciatic nerve injury. Five hips dislocated postoperatively and six others had recurrent subluxation. Replacement of the acetabular component was required in four hips, three because of loosening and the other for malposition in association with paraparesis. Trochanteric osteotomy was done in nine hips and four failed to unite. There was roentgenographic evidence of femoral component loosening in 28% of the hips and 8% required replacement. Poor cement filling and varus positioning of the femoral stem contributed to loosening.

General and specific complications of revision hip arthroplasty using fresh bone allografts may affect the postoperative functional outcome to different extent. The aim of this paper was to estimate the incidence and types of intraoperative and early postoperative complications after revision hip arthroplasty, and to clinically and radiographically evaluate their influence on the final postoperative outcome. The most frequent general intraoperative complications were: femoral fracture (6.7%) and lesion of the superior gluteal artery. Anterior dislocation of the prosthesis (6.7%) and superficial infection (3.3%) were the two most frequent early postoperative complications. Of all general complications taken into account, femoral fracture, either intra or postoperative, has the worst prognosis. Bone allograft resorption, as the only specific complication encountered in this study, has a bad prognosis only if it is very extensive. The use of fresh bone allografts, prepared in a special manner, is clinically safe for revision total hip arthroplasty, if a bone bank is not available. .

Objective To retrospectively study the perioperative complications and postoperative function recovery of 93 patients treated with simultaneous bilateral total hip arthroplasty (THA). Methods A total of 93 patients (186 hips) undergone simultaneous bilateral THA from January 1999 to January 2009 in our hospital were involved in this study. There were 70 males and 23 females (at age range of 25-65 years, average 41. 8 years). The preoperative diagnosis included bilateral avascular necrosis of femoral head in 48 patients, rheumatoid arthritis in 11, developmental dysplasia of the hip in 26 and ankylosing spondylitis in 8. The intraoperative blood loss, Harris scores before operation and at final followup as well as perioperative complications were analyzed. Results All the patients were followed up for average 65 months (12-118 months), which showed femur fracture in one patient and infection six months after discharge in one patient. The Harris score was increased from (36.7 ±6.1) points preoperatively to (91.2±6.2) points at the final follow-up. Hip pain disappeared in 92 patients after operation and radiograph showed no loosening. Actebular loosening occurred in one patient 49 months after operation and was revised accordingly. Conclusion Under strict control of operation indications, suitable choice and implantation of the prosthesis and emphasis on perioperative management and postoperative rehabilitation, simultaneous bilateral THA is a safe and effective choice for bilateral hip diseases.

Total knee arthroplasty (TKA) for hemophilic (factor VIII deficiency) arthropathy is a complex and demanding procedure with a high complication rate. However, the long-term benefits have not previously been reported. This study reviews 19 TKAs performed for hemophilic arthropathy that were followed for a minimum of 5.5 years and an average of 9.5 years. At present, 13 knees have good or excellent results, and six knees rate as poor or failures. Those patients with excellent results have maintained good pain relief and function. Four of the six failures were among the first seven arthroplasties performed, when only 80% factor VIII coverage was used during the perioperative period. Since the use of 100% factor VIII coverage was instituted, the failure rate has declined. Ten of the 19 knees suffered complications, including one deep infection, six superficial skin necroses, three nerve palsies, seven postoperative bleedings, and one transfusion reaction. Six of the seven knees operated on under 80% factor VIII coverage had complications. Once 100% factor VIII coverage was instituted, the only complications included one skin necrosis and three postoperative bleedings. The roentgenographic failure rate has remained high with progressive roentgenographic lucencies in 13 of 19 tibial components, associated with component shift in three knees. While these roentgenographic findings have not necessarily correlated with clinical results, they are disturbing and may portend future failures. However, pain relief and improved function are maintained at longer follow-up times. The best results were obtained under 100% factor VIII coverage using a posterior stabilized prosthesis and patellar resurfacing.

Five hundred eight consecutive cases (481 patients) treated with the extensively porous coated Anatomic Medullary Locking prosthesis were followed for an average of 9 years (range, 5-14 years). Thirty-one (6%) hips were lost to followup and 33 (7%) hips had complications that required revision surgery. The indications for revision were symptomatic stem loosening (six cases), symptomatic cup loosening (five cases), asymptomatic periarticular osteolysis (seven cases); trochanteric fracture through an osteolytic cyst (four cases), polyethylene fracture (five cases), sepsis (one case), and heterotopic ossification (one case). The surgical treatment of these complications is described. After these revisions, 11 (33%) cases had additional complications, most commonly a dislocation. Four required a second revision. Questionnaires and physical examinations were used to compare the outcome of the cases requiring revision with the outcome of those that did not. There were no differences in patient satisfaction between cases requiring revision surgery and those that did not (97% and 95% patient satisfaction, respectively). Function was also similar between the two groups, with 93% reporting increased function in each group.
