Subchondral acetabular edema and cysts, as a consequence of degenerative changes of the hip, are associated with disability, pain, and worsened function in this joint. Patient-reported outcome (PRO) scores including visual analog scale, modified Harris hip score (mHHS), non-arthritic hip score and hip outcome score sports-specific subscale (HOS-SSS) were gathered preoperatively, at 3 months, and annually thereafter. However, there remains a subset of hips with relatively maintained joint space but with acetabular subchondral edema and cystic change with unknown outcome on magnetic resonance imaging (MRI).

These were based on an MRI interpretation from a board certified radiologist. By continuing to browse This study is the largest study in the literature to date that has examined clinical outcomes of hip arthroscopy in patients with preoperative subchondral cysts noted on MRI. Magnetic resonance imaging (MRI), conducted in patient NO. Hip impingement can lead to significant chondral damage as the head neck junction impacts the acetabular rim and causes both labral tearing and chondral injury. The procedures carried out at the time of hip arthroscopy are noted on Table II. Patients that required total hip arthroplasty (THA) or revision surgery were noted in the institutions prospective database. F/u, follow-up; BMI, body mass index; THA, total hip arthroplasty; mHHS, modified harris hip score; NAHS, non-arthritic hip score; HOS-SSS, hip outcome score-sports specific subscale; VAS, visual analog score. Subchondral bone cysts (SBCs) are sacs filled with fluid that form inside of joints such as knees, hips, and shoulders. Patients demonstrated significant improvement in all PRO scores and VAS from the preoperative state, with a patient satisfaction of 7.2. The MCID score was utilized in this study to demonstrate how many patients had a perceivable improvement in their PRO scores from the preoperative state. Femoral or acetabular cysts did not have a different rate of need for conversion to THA (Table IV). 10.1016/j.joca.2006.05.011 [Google Scholar] Chan P. M. B., Wen C., Yang W. C., Yan C., Chiu K. (2017). There were four patients (6.1%) that required revision arthroscopy, which was carried out at an average of 30 months from the time of surgery. Surgical treatment of femoroacetabular impingement: what are the limits of hip arthroscopy? How the bone cyst in hip can destroy the bone in the affected location. MR Technique: The exam was acquired on a 64-channel 3 T scanner (Siemens MAGNETOM Skyra). AOSSM members have access to this journal as part of their membership. Between February 2008 and March 2013, there were 1517 hip arthroscopies conducted at this institution by the senior author (B.G.D.). Subchondral means under the cartilage and refers to fluid filled cavities within the bone that is under the cartilage. Mean patient satisfaction was 7.2. Like any other bone cyst, hip bone cyst is a benign bone tumor. Seventeen patients required reoperation [13 total hip arthroplasty (THAs) and 4 revision arthroscopies].
