Clinical Outcomes of the Central Third Patellar Tendon Versus Four-strand Hamstring Tendon Autograft Used for Anterior Cruciate Ligament Reconstruction: A Systematic Review and Subgroup Meta-analysis of Randomized Controlled Trials.

Background: The most frequently used auto-grafts for ACL reconstruction (ACLR) are bone-patellar tendon-bone (BPTB) and four-strand hamstring tendon (4S-HT), but significant controversy exists about which graft is better. This study aimed to compare the knee outcomes following ACLR with BPTB and 4S-HT autografts.

Methods: Subgroup meta-analyses were performed basing on available randomised controlled trials (RCTs) according to different follow-up intervals.

Outcomes of Intercalary Prosthetic Reconstruction for Pathological Diaphyseal Femoral Fractures Secondary to Metastatic Tumors.

Objective: To evaluate the clinical outcomes and complications of segmental prosthetic reconstruction for pathological diaphyseal femoral fractures secondary to metastatic tumors.

Methods: Between 2011 and 2015, we retrospectively evaluated 16 patients (6 men and 10 women; 64.5 ± 11.

Management of great vessels and nerves in limb-salvage surgery for bone and soft tissue tumors.

In recent years, limb-salvage surgery has gradually replaced amputations and become one of the main treatment strategies for patients with bone and soft tissue tumors of the extremities. The goals of tumor resection in limb-salvage surgery are to reduce the recurrence rate and preserve as much limb function as possible. However, depending on the size and specific location of the tumor, large neurovascular bundles may be involved.

Tissue-engineered calcium phosphate cement in rabbit femoral condylar bone defects.

Background: Calcium phosphate cement (CPC) is a favorable bone-graft substitute, with excellent biocompatibility and osteoconductivity. However, its reduced osteoinductive ability may limit the utility of CPC. To increase its osteoinductive potential, this study aimed to prepare tissue-engineered CPC and evaluate its use in the repair of bone defects.
