Bicruciate retaining.

Total knee replacement (TKR) is a procedure used to treat knee arthropathy. Patients' dissatisfaction is still relevant (literature reports dissatisfaction rates as high as 40%). The anterior cruciate ligament is usually removed while performing a total knee arthroplasty, thus changing knee biomechanics. As patients' mean age to surgery is decreasing, bicruciate retaining models, which preserve normal biomechanics, may be useful in increasing patients' outcomes. Limited data concerning bicruciate retaining arthroplasty is available; although clinical results are encouraging, there are concerns regarding surgical exposure, anterior cruciate integrity evaluation, and implant fixation.

Cementless total hip replacement for severe developmental dysplasia of the hip: our experience in Crowe's group IV.

Total hip replacement in developmental dysplasia of the hip grade IV of Crowe's classification presents some difficulties. In this study, we present our results of the treatment for this pathology, also describing the surgical techniques used and the complication we had. In this paper, 18 total hip replacements in developmental dysplasia of the hip Crowe IV were studied clinically and radiologically before and after surgery, with a mean follow-up of 4.2 years (min: 1 year). The average Harris Hip Score improved from 52 to 89. The average leg lengthening was 36 mm. When a subtrochanteric shortening osteotomy was performed, the healing occurred in all cases, in an average time of 5.3 months. At now, the implant survivorship is 100% (no revision required). The techniques and principles described in this paper allow to achieve good results in this surgery. An accurate preoperative evaluation and the availability of specific materials are also important steps. The subtrochanteric shortening is a safe procedure to avoid neurovascular injuries.

Fibrin tissue adhesive reduces postoperative blood loss in total knee arthroplasty.

BACKGROUND: Blood transfusion is often required in total knee replacement; various methods of blood preservation have been studied. The best solution is to reduce the loss of blood during and after surgery. MATERIALS AND METHODS: We designed this study to evaluate the hemostatic efficacy and safety of fibrin tissue adhesive (Quixil) in patients receiving total knee arthroplasty [low contact stress (LCS, DePuy, Warsaw, IN, US) cementless total knee replacement (TKR)] with a prospective, randomized, standard treatment controlled study. Thirty-five patients were randomized to receive treatment with fibrin tissue adhesive (treatment group), and 35 were randomized to be managed with postoperative blood recovery and reinfusion (control group). Blood loss in suction drain, decrease in hemoglobin values, and transfusions were recorded. RESULTS: A significant reduction in apparent total blood loss was detected in the treatment group compared with the control group. There was also a lower decrease in hemoglobin level, although this difference was not significant. When fibrin tissue adhesive was administered, the need for transfusions was lower. No major adverse events were recorded in our series. CONCLUSIONS: Fibrin tissue adhesive reduced blood loss in TKR and seemed to significantly reduce the need for blood transfusion. Fibrin tissue adhesive can be an appropriate solution to enhance hemostasis and vessel sealing at the operative site in TKR, in order to reduce blood loss after surgery and the risk of complications.
