Comparative clinical efficacy of "Figure-8" Banding and double-row anchor suture-bridge fixation in arthroscopic management of tibial intercondylar eminence avulsion fractures.

Objective: The objective of this study is to assess and compare the clinical efficacy of "Figure-8" banding and double-row anchor suture-bridge fixation techniques in the arthroscopic management of tibial intercondylar eminence avulsion fractures.

Method: A retrospective analysis was conducted on the medical records of 42 patients who underwent arthroscopic surgery for tibial intercondylar eminence fractures at our institution from June 2017 to June 2022. This cohort included 20 cases treated with "Figure-8" banding and 22 cases managed using double-row anchor suture-bridge fixation.

Effect of Computer-guided Operations on Improving the Distal Femoral Flexion Angle on the Sagittal Placement of Femoral Prosthesis in Total Knee Arthroplasty.

Background: The precise placement of prosthesis in total knee arthroplasty (TKA) surgery significantly impacts the postoperative outcomes and the long-term survival rate of prosthesis. While the optimal coronal position of femoral prosthesis has been extensively researched, there remains a gap in the study of sagittal placement. Therefore, our aim is to investigate the impact of the distal femoral flexion angle (DFFA) on the sagittal placement of femoral prosthesis in TKA.

Identification of critical genes and gene interaction networks that mediate osteosarcoma metastasis to the lungs.

Osteosarcoma (OS) is the most commonly diagnosed bone tumor in young adults under the age of 20. Metastasis is considered an important factor underlying cancer-associated morbidity and mortality, and, as a result, the survival rate of patients with metastatic OS is low. In spite of this, the mechanisms underlying metastasis in OS are currently not well understood.

Endosialin‑expressing bone sarcoma stem‑like cells are highly tumor‑initiating and invasive.

It has been reported that the presence of a small group of cancer stem‑like 'side population (SP)' cells is responsible for therapy failure and tumor recurrence. The present study demonstrated that primary human osteosarcoma samples contained a SP of about 3.9% which overexpressed ABC transporters, including ABCA1, ABCB1, ABCB2 and ABCG2, which are associated with drug resistance and may have contributed to multi‑drug resistance of SP cells.

[Efficacies of percutaneous multiple needle puncturing for releasing hip adductor muscle during total hip arthroplasty].

Objective: To summarize our experiences of applying percutaneous multiple needle puncturing technique for releasing adductor muscle during total hip arthroplasty (THA) for ischemic necrosis of femoral head and provide rationales for clinical practice.

Methods: From January 2008 to December 2012, 36 adult patients with ischemic necrosis of femoral head (36 hips) and 36 adult patients with femoral neck fracture (36 hips) were recruited. The group of ischemic necrosis of femoral head was designated as experiment group in which there were 29 males and 7 females with an average age of 67.
