An introduction is presented in which the editor discusses various reports within the issue on topics including the method of total hip arthroplasty, use of direct anterior approach in the U.S. and role of surgeon in patient's care.

The article discusses the developments in the discipline of total hip arthroplasty. It highlights various issues and challenges of total hip arthroplasty devices and procedures including recalls of devices due to failure and the biological reactions to the metal bearing and at the modular junction. It explores the clinical outcome of total hip arthroplasty, its metal bearing wear and corrosion, and implication device recalls.

The article presents information about the total hip arthroplasty which remains as effective and safe orthopaedic reconstructive procedures. It informs that most of investigators believe that the adverse reactions have been seen in association with metal-on-metal bearings due to bearing wear and corrosion at the taper junction. It mentions that quality outcome measures for both the hospital and orthopaedic surgeons have been evaluated and developed for the total joint arthroplasty.

The article presents several excerpts from the reports that were published in "The Journal of Bone and Joint Surgery," "The Journal of Arthroplasty," and "Clinical Orthopaedics and Related Research" during April 2010 to April 2011.

Information about several papers discussed at an meeting sponsored by the American Academy of Orchopaedic Surgeons (AAOS) on total hip arthroplasty (THA) is presented. Topics include the surgery complications of THA, clinical outcome of primary and revision total hip arthroplasty and socioconomic and practice management issues. It also focuses on the efficacy of metal-on-metal bearings and hip resurfacing arthroplasty.

The article offers updates on total hip arthroplasty. It includes the outcome of primary total hip replacement, revision of hip arthroplasty, hip resurfacing arthroplasty, complications and practice management. In addition, information in the past year in epidemiology and hip resurfacing arthroplasty is offered.

The article presents an overview of research which has looked at innovations in total hip arthroplasty, new methods of the enhancements of bone growth and fixation, hip resurfacing arthroplasty and minimal incision surgery. A discussion of the complications of arthroplasty, of the medical-legal issues related to it,and of changes which have been seen in the orthopedic industry-orthopedic surgeon relationship, is presented.

The article discusses various reports published within the issue, including one about the total hip arthroplasty cases among eight million hospital discharge records and another about the comorbidities of hip arthroplasty.

The article presents a review on the total hip arthroplasty surgery. In this review, related data on outcomes, biomaterials, surgical techniques, the treatment of complications, and socioeconomic issues were taken. This review is formed into seven sections including primary surgery, surface replacement, revision surgery, biomaterials and prosthetic design, surgery complications, practice management, and treatment of intracapsular hip fractures.

The article presents information on hip arthroplasty. Total hip arthroplasty is one of the most clinically efficacious and cost-effective medical interventions. There has been little new information on the clinical outcome of cementless hip arthroplasty. Implants with a coating of hydroxyapatite have been widely used. Recently, there has been a resurgence of interest in resurfacing arthroplasty. Sales of resurfacing implants have become one of the fastest-growing segments in the worldwide market.

Reports on developments in hip arthroplasty. Factors involved in the failure of fixation of a cemented stem; Limitations of biomechanical machine testing; Clinical relevance of micromotion between the cementless stem and the host bone; Major clinical advantage of cross-linked polyethylene in hip arthroplasty.

The article presents a study on the minimally invasive anterior approach for total hip arthroplasty. Such approach provides access to the hip through a small skin incision and secondary incisions for the acetabular and femoral instruments. The researchers believe that the minimally invasive nature of the technique leads to low blood loss and low complication rates by keeping soft-tissue trauma to a minimum. Smaller incisions also lead to faster postoperative mobilization and rehabilitation.

Focuses on challenges associated with total hip arthroplasty procedure in orthopedic surgery. Comparison between cement fixation and without cement fixation technique for femoral stern; Need to minimize complications and effectively manage total hip arthroplasty; Analysis of outcomes of total hip arthroplasty in community orthopedic practice; Advantage of one-stage bilateral total hip arthroplasty.
