The efficacy of preoperative tranexamic acid administration among patients undergoing arthroscopic rotator cuff repair: A systematic review and meta-analysis of randomized controlled trials.

Aim: To conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) that investigated the effectiveness of tranexamic acid (TXA) among patients undergoing arthroscopic rotator cuff repair (ARCR).

Methods: Five databases were screened until December 18, 2022. The included RCTs were assessed for risk of bias, and the endpoints were summarized as mean difference/standardized mean difference (MD/SMD) or risk ratio (RR) with the 95% confidence interval (CI) in a random-effects model.

Preoperative Denosumab plus Surgery in the Management of Giant Cell Tumor of Bone: A Comprehensive Narrative Literature Review.

Giant cell tumor of bone (GCTB) is a biologically benign osteolytic tumor that affects the metaphyseal/epiphyseal portions of bones. Histologically, GCTB is composed of osteoclast-like multinucleated giant cells that express receptor activator of nuclear factor kappa B (RANK), and neoplastic mesenchymal stromal cells that express RANK ligand (RANKL). The pathogenesis of GCTB is primarily attributable to the RANK-RANKL interaction, resulting in the activation of osteoclasts and the resultant osteolytic phenotype.
