A Prospective Randomized Controlled Trial Assessing the Impact of Preoperative Combined with Postoperative Progressive Resistance Training on Muscle Strength, Gait, Balance and Function in Patients Undergoing Total Hip Arthroplasty.

Purpose: The aim of this study is to investigate the effects of a preoperative combined with postoperative moderate-intensity progressive resistance training (PRT) of the operative side in patients with hip osteoarthritis (HOA) who are undergoing total hip arthroplasty (THA). The study seeks to evaluate the impact of this combined intervention on muscle strength, gait, balance, and hip joint function in a controlled, measurable, and objective manner. Additionally, the study aims to compare the outcomes of this combined intervention with those of preoperative or postoperative muscle strength training conducted in isolation.

[Applied research on autologous bone graft for acetabular defect of Crowetype III and IV hip dysplasia].

Objective: To study clinical efficacy of autologous bone graft for acetabular defect of Crowe III and IV hip dysplasia.

Methods: The 22 patients with 25 hips of DDH (Crowe type III, IV) from March 2010 to May 2013 were retrospectively analyzed. Total hip arthroplasty (THA) combined autogenous bone grafting was performed for all these patients with osteoarthritis secondary to DDH.

[Renovation stem revision femoral head arthroplasty for unstable intertrochanteric fracture in the elderly].

Objective: To observe clinical efficacy of renovation stem revision femoral head arthroplasty for the treatment of unstable intertrochanteric fracture in the elderly.

Methods: Totally 32 elderly patients with unstable intertrochanteric fracture were treated with renovation stem revision femoral head arthroplasty from September 2007 to January 2011. There were 11 males and 21 females with an average age of 83.
