The anterior approach for total hip arthroplasty (THA) has been associated with a faster earlier functional recovery and has gained increasing utilization for primary THA exposure. However, some studies have suggested a higher risk of femoral complications, as well as difficulty with femoral exposure. Techniques of soft tissue releases have been described to offer better femoral exposure, and to help mitigate complications like femoral fracture or breach of the canal with broaching. However, appropriate titrated soft release remains important to decrease potential risk of dislocation. Here we present a suggested technique and hierarchy of soft tissue releases to adequately expose the femur. In addition, we discuss adjunctive table and patient position maneuvers for femoral exposure, as well as more extensile and revision techniques if necessary.

Introduction

The purpose of the study was to assess the clinical outcomes of an algorithm for soft tissue femoral release in anterior approach (AA) total hip arthroplasty (THA). Specifically, the following were assessed in this series of patients utilizing a standardized soft tissue release sequence: 1) clinical outcomes with the Harris Hip Score (HHS); 2) re-operation rates; 3) component survivorship; and 4) complications.

Non-traumatic osteonecrosis of the femoral head is a potentially devastating condition, the prevalence of which is increasing. Many joint-preserving forms of treatment, both medical and surgical, have been developed in an attempt to slow or reverse its progression, as it usually affects young patients.

However, it is important to evaluate the best evidence that is available for the many forms of treatment considering the variation in the demographics of the patients, the methodology and the outcomes in the studies that have been published, so that it can be used effectively.

The purpose of this review, therefore, was to provide an up-to-date, evidence-based guide to the management, both non-operative and operative, of non-traumatic osteonecrosis of the femoral head.

Introduction

There is a paucity of studies analyzing the rates of revision total knee arthroplasty in diabetic patients stratified by glycated hemoglobin levels. The purpose of this study was to: 1) determine the incidence of revision TKA; 2) correlate the percent of glycated hemoglobin with incidence of revision; and 3) determine the cause of revision in diabetic patients stratified by glycated hemoglobin level.
