The concept of femoro-acetabular impingement (FAI) rests on three pillars: cam-deformity, pincer-deformity and abnormal femoral torsion. Several treatment modalities exist, ranging from conservative management to open or arthroscopic surgery. The type of treatment depends on the pathomorphology, the severity of symptoms, thepatient's age and the extent of the degenerative lesions. The aim of treatment is to reduce pain, obtain a physiological range of movement as well as a stable hip, and ideally to delay the onset of secondary osteoarthritis in the long term. A first article dealt with the concept and diagnosis of FAI, this one takes a look at its treatment.

Revision Hip Arthroscopy Terrible Triad: Capsular Deficiency, Labral Deficiency, and Femoral Over-Resection.

Revision hip arthroscopy is increasingly common and most often performed to treat residual femoroacetabular impingement caused by cam under-resection. Unfortunately, other pathologies encountered during revision hip arthroscopy are more difficult to treat, including capsular deficiency, labral deficiency, adhesion formation, and/or cam over-resection. When encountered, these various pathologies should be comprehensibly corrected with the goals of restoring anatomy, re-establishing the hip fluid seal, and ensuring impingement-free motion.

Purpose: The learning curve of a single surgeon performing hip arthroscopy is reported to be steep, but, to date, the inflection point after which procedures are more successful is still unknown. The aim of this study was to design a learning curve focused on clinical outcomes, complications and revision/conversion rates.
Methods: Seventy-one hip arthroscopies performed for femoroacetabular impingement (FAI) by a single surgeon, with a minimum follow-up of 5 years, were considered.

Background: Acetabular subchondral cysts are commonly identified signs of joint degeneration and arthritis. This pathology is generally considered a relative contraindication for hip preservation surgery.
Purpose: To investigate the effect of arthroscopic bone grafting for the treatment of acetabular subchondral cysts.

Femoroacetabular impingement syndrome (FAIS) is a common condition of the hip that can cause significant damage to the joint, leading to degeneration and osteoarthritis. FAIS constitutes an abnormal and dynamic contact between the femoral head-neck junction and the acetabular rim, resulting from altered bone morphology at one or both sites. Repetitive trauma at the site of impingement generates progressive damage to the acetabular labrum, chondrolabral junction, and articular cartilage.

Previous studies suggest a relationship between femoroacetabular impingement (FAI) and femoral neck stress fractures (FNSF), due to pathologic biomechanics in the setting of femoral head abutment (cam morphology) and/or acetabular overcoverage (pincer morphology). The purpose of this study is to evaluate the association between cam or pincer morphology and FNSF, compared to a control group of patients without hip pain. A retrospective review of the electronic medical record at a single institution was queried for patients with FNSF over a 10-year time period from January 2011-2021.
