Full-thickness acetabular articular cartilage defects (FAACD) are found on most hips with femoroacetabular impingement (FAI) with a wave sign in the acetabulum. When not repaired it can produce pain and catching sensation. Multiple arthroscopic techniques for repairing this chondral lesion exist, but only few show the quality of the repair on a second look. The purpose of this study is to evaluate the quality of the repaired cartilage during revision hip arthroscopy (RHA) allowing a second look in patients treated of FAACD. A total of 13 hips with FAACD repaired in the past underwent RHA for ongoing pain. Signs of persistent chondral defects or the ability to elevate the articular cartilage from subchondral bone were evaluated by zones. Those with persistent defects were re-repaired. All patients had FAACD lesions in zones I, II and III diagnosed in the index hip arthroscopy. The most common finding at the RHA was the presence of bone growth or residual impingement. Before FAACD repair, 11 (85%) hips had the wave sign, while 2 (15%) hips had it in RHA. Five (38%) hips had residual delamination in the second look, these patients had residual FAI, were ≥58 years or waited >6 months to be revised. The wave sign was not observed in 85% of the revised hips, indicating the technique was successful in most cases and was not the principal cause of their ongoing pain. This technique achieved the stated goal of stabilizing the articular cartilage seen in the wave sign.
With the recent increase in the use of hip arthroscopy, revision hip arthroscopy also has become more prevalent; nevertheless, it is often complex, and many factors should be considered to achieve a satisfactory clinical outcome. Labral reconstruction or augmentation technique is used in cases of severely deficient acetabular labral tissue to restore the fluid seal mechanism. In cases of previous over-resection of cam impingement, the remplissage technique, used to restore the bony defect of the femoral headeneck junction and preserve the joint seal, is an established technique that has been recently reported in the hip with the use of iliotibial band with the same aim as in the shoulder, filling in of the defect due to healing of the soft tissue to the underlying bony impression. We aim to describe a labrum reconstruction in combination with a remplissage of the femoral headeneck junction with a dermal graft in a patient with recurrent hip pain after hip scope. This combination may improve hip stability and reduced pain after failed hip scope.
The primary aim of the study is to determine the rate of traction-related complications in hip arthroscopy (HA) including perineal compression and distraction injuries, and the secondary objective is to report the incidence of complications in HA found on the studies selected by a systematic review. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for data extraction from the PubMed and Cochrane databases obtained in February 2022. Reviewers extracted the title, author, date of publication, number of hips treated and number of complications describing the affected area, nerve and soft tissue injury related to traction. Studies on postless HA and HA combined with other procedures were excluded. Twenty-six years of HA literature was found in the search that included 35 studies and 8126 hips (89% Level IV) that reported the complications found during the procedure and described complications related to traction. A total of 623 hips (7.7%) had some sort of complications during HA, and complications related to traction were in 227 hips (36%). Injuries caused specifically by the perineal compression were in 144 hips (23%) that included the pudendal nerve and soft tissue injury of the groin area. Complications caused by the distraction were in 83 hips (13%) that included sciatic and peroneal nerve injury, numbness or pain of ankle and foot. HA complications occurred in 7.7% of hips treated, which is found in this systematic review. One-third of the complications are related to traction, 23% are caused by perineal compression and 13% are caused by distraction.
Osteoid osteoma located on the hip joint presents with atypical symptoms that can be misdiagnosed or missed. Multiple image studies can be made for diagnosis but OO should be suspected to properly choose the right one. Percutaneous resection with CT guidance is a reproducible and accurate technique with the appropriate tools and a specialist team to obtain optimal results.
