Low-volume formulation of intra-articular tranexamic acid, 25-ml tranexamic acid (2.5 g) plus 20-ml saline, is effective in decreasing blood transfusion rate in primary total knee replacement even without preoperative haemoglobin optimization.

Unlabelled: The efficacy of intra-articular tranexamic acid (TXA) to decrease blood loss after total knee replacement (TKR) has been confirmed in randomised clinical trials (RCTs) and meta-analysis. However, insufficient data are still available about the efficacy in clinical practice of intra-articular TXA administration in reducing the rate of postoperative blood transfusion. To prove the efficacy of a low-volume formulation of intra-articular TXA in current clinical practice, and the role of preoperative variables to influence the transfusion risk after primary TKR.

Revision knee arthroplasty with a rotating-hinge design in elderly patients with instability following total knee arthroplasty.

Background: Revision knee arthroplasty with a rotating-hinge design could be an option for the treatment of instability following total knee arthroplasty (TKA) in elderly patients.

Purpose: To evaluate the clinical and radiographic results of revision arthroplasties in TKAs with instability using a rotating-hinge design in elderly patients.

Methods: We retrospectively reviewed 96 rotating-hinge arthroplasties.

Arthroscopic debridement for ankle haemophilic arthropathy.

The purpose of this study is to describe the results of arthroscopic ankle debridement (AAD) with the aim of determining whether it is possible to avoid or delay ankle fusion or total ankle replacement for advanced haemophilic arthropathy of the ankle in young patients. In a 12-year period (2000-2011), 24 AADs (one bilateral in two stages) were performed for advanced haemophilic arthropathy of the ankle in 23 patients (22 had haemophilia A, 1 haemophilia B, 0 with inhibitors against the deficient factor). Their average age at operation was 25.

Arthroscopic BPTB graft reconstruction in ACL ruptures: 15-year results and survival.

Purpose: The aim of this study is to investigate the 15-year results and survival of arthroscopic ACL reconstruction using the central-third patellar bone-tendon-bone (BPTB) autograft.

Methods: ACL BPTB reconstruction was performed in 250 consecutive patients. Of these patients, 88% returned for a follow-up examination at 15 years after reconstruction.
