The debate over preserving or sacrificing the posterior cruciate ligament (PCL) in mobile-bearing TKA (MB TKA) still needs to be solved due to the lack of high-quality evidence, particularly meta-analyses comparing these techniques. This study aims to conduct a meta-analysis to compare the outcomes of PCL retention (CR) and PCL sacrifice (PS) in terms of clinical and functional knee scores, range of motion, complication rates, and revision rates and to validate these findings through animal experiments. A comprehensive search was conducted using MEDLINE, Cochrane, and Embase databases. Relevant studies were selected for the meta-analysis using RevMan 5.3. Additionally, an animal experiment using Sprague-Dawley rats simulated MB TKA to compare the effects of PCL retention and sacrifice surgeries. 12 studies were included in the meta-analysis. No significant differences were found between CR and PS techniques regarding HSS, KSS, KSFS, WOMAC, ROM, and medial/lateral instability. However, CR MB showed slight superiority in NKJS, while PS MB had better outcomes in complication and revision rates. In the animal study, CR rats exhibited significant early postoperative inflammation, but both groups' knee structures gradually normalized. The meta-analysis indicates that PCL retention (CR MB) and sacrifice (PS MB) have similar effects on various clinical and functional knee scores. However, PS MB is significantly better at reducing complications and revision rates. The animal experiment confirms PS MB's advantages in reducing inflammation and promoting joint recovery.

While approved for giant cell tumours, its role in aneurysmal bone cysts (ABC) remains unclear. This review explores denosumab's application in ABCs, focusing on its role, outcomes, and adverse effects. <b>Methods:</b> A scoping review adhering to PRISMA Extension for Scoping Reviews guidelines was conducted. The search involved five databases from inception until 31 December 2023. <b>Results:</b> From an initial 390 studies, 29 were selected post-screening involving 67 patients. The most common ABC sites were the spine (<i>n</i> = 42) and pelvis (<i>n</i> = 7).
