[Coxalgia]

Coxalgia is one of the most common painful complaints in orthopedic surgery. The management of a "traumatic" hip is relatively well codified, however atraumatic coxalgia is more difficult to diagnose and explore. The history and a well-conducted clinical examination are essential for the management of coxalgia. The diagnosis is already well oriented by a simple X-ray and the presence or absence of inflammatory signs on the blood test. This article aims to provide a guideline for the diagnostic approach to coxalgia.

[How I explore… a non-traumatic gonalgia]

Because the knee is the joint of the human body with the largest surface, it is no wonder that gonalgia is one of the most common complaints in the general population. Although the management of a painful traumatic knee is relatively well standardized, that of a non-traumatic knee pain is less codified. History and a rigorous systematic clinical examination play a key role in the management of nontraumatic gonalgia. The diagnostic approach is mainly guided by the inflammatory or mechanical nature of the pain and its topography. This article aims to clarify the diagnostic approach to gonalgia without notion of prior trauma.

[Arthroscopy of the hip : management of femoro-acetabular conflicts before the osteoarthritic stage]

Hip arthroscopy is a technique that has been shown to be effective in the treatment of femoro-acetabular lesions. These are related either to an anomaly on the anterior aspect of the femoral neck ("cam effect") or an anomaly at the level of the acetabular margin ("pincer effect") or a combination of both. The main arthroscopic gesture for the cam conflict consists of a femoroplasty, i.e. a regularization of the anterior bone bump. Other gestures, such as reinsertion of the labrum and cartilage repair, can be contemplated during the same operation. In a pincer conflict, an acetabuloplasty associated with re-insertion of the labrum can be performed. Hip arthroscopy is a technique in progress in terms of the surgical technique as well as the number of skilled surgeons. It aims to slow down the osteoarthritic evolution of the hip joint in the context of femoro-acetabular conflicts. However, it remains a tech¬nique with a long learning curve and possible side effects or complications are not to be neglected.
