Background: As hip arthroscopy has expanded in popularity and volume, more information is needed about indications for the procedure predictive factors of clinical outcomes. Purpose: To evaluate outcomes a prospective study to analyze cohort identify that are improvement. Study Design: Case-control study; Level evidence, 3. Methods: Data were collected prospectively on all patients undergoing between February 2008 June 2012. We included who agreed participate completed 4 patient-reported...
Background: Osteoarthritis adversely impacts hip arthroscopy outcomes. The purpose of this study was to conduct a matched-pair analysis with mean follow-up 2 years evaluate the outcomes following in patients Tönnis grade-2 osteoarthritis. Methods: Data were prospectively collected on all undergoing during period from April 2008 December 2012. Patients excluded if they had previous conditions. categorized into grade-0, grade-1, or osteoarthritis groups and matched 1:1 ratio according age...
Background: Inconsistencies in the workup of labral tears hip have been shown to result a delay treatment and an increased cost medical system. Purpose: To establish consensus statements among Canadian nonoperative/operative sports medicine physicians via modified Delphi process on diagnosis, nonoperative operative management, rehabilitation return play (RTP) those with hip. Study Design: A statement. Methods: total 40 (50% orthopaedic surgeons) were selected for participation based their...
Background: Surgical intervention for partial and full-thickness gluteus medius tears is often recommended patients who have persistent pain despite nonoperative treatment. Traditionally, the surgical has been carried out through open techniques with good results; however, advantages of endoscopic include less tissue dissection, improved tendon mobilization, benefit arthroscopic correction intra-articular pathological conditions. The purpose this report to provide an update on a previously...
Atraumatic instability or microinstability of the hip is a recognized cause groin pain and instability. Risk factors include female sex, ligamentous laxity, borderline dysplasia. Arthroscopically, joint may distract easily, there be associated ligamentum teres tears laxity capsule on manual probing. The use arthroscopic capsular plication in this cohort patients has shown good to excellent results. Biomechanically, aims create an imbrication inferior shift augment screw-home mechanism...
Improvements in pain, function, and patient satisfaction are used to evaluate the outcomes of hip arthroscopic surgery.To identify correlations between visual analog scale (VAS) score for pain with 4 commonly patient-reported outcome (PRO) scores determine what extent changes these 2 parameters reflected each PRO scores.Cohort study (diagnosis); Level evidence, 3.Patients undergoing surgery February 2008 2013 were assessed prospectively before surgery, at 3 months, annually thereafter...
Hip pain remains a challenge given the multiple factors that can cause damage to articular cartilage, such as traumatic injury, metabolic damage, and morphologic variations femoroacetabular impingement (FAI) contribute progression of osteoarthritis. However, direct relationship between patient characteristics, extent acetabular chondral topologic characteristics lesions has not been established.To compare grade measured in terms labrum disruption (ALAD) classification, size position lesions,...
Microfracture in hip preservation surgery has demonstrated favorable outcomes, but studies with a higher level of evidence assessing microfracture are warranted.To assess 2-year outcomes patients who underwent arthroscopy full-thickness chondral damage treated and compare these those control group from similar cohort did not have were microfracture.Cohort study; Level evidence, 3.Between February 2008 May 2012, prospectively gathered data for undergoing during follow-up reviewed. All...
Background: With the rapid increase in hip preservation procedures, revision arthroscopic surgery and conversion to total arthroplasty (THA) or resurfacing (HR) after primary have become a large focus recent literature. Purpose: The purpose was perform survival analysis mixed cohort of patients undergoing at high-volume tertiary referral center for with minimum 2-year follow-up. secondary compare clinical outcomes versus surgery. Study Design: Cohort study; Level evidence, 2. Methods: From...
The primary purpose of this review article is to discuss the role diagnostic, corticosteroid, hyaluronic acid (HA) and platelet rich plasma (PRP) in treatment osteoarthritis (OA) femoroacetabular impingement (FIA). These treatments play an important biological non-operative management these conditions. Two independent reviewers performed search PubMed for articles that contained at least one following terms pertaining intra-articular hip injection—local anaesthetic, ultrasound, fluoroscopic,...
Gluteus medius tears are a common cause of lateral hip pain. Operative intervention is usually prescribed for patients with pain despite physical therapy and/or peritrochanteric injections.To identify clinical features that predict operative in gluteus tears.Case control study; Level evidence, 3.A matched-pair controlled study was conducted on who underwent endoscopic repairs from June 2008 to August 2014 full-thickness tears. The exclusion criterion previous disorders (eg,...
Purpose This study aims to present 3 patients’ results after undergoing gluteus maximus and tensor fascia lata (TFL) transfer for chronic abductor tears unable be repaired primarily. Methods patients were identified intraoperatively as having an tear The anterior 1/3 of the posterior TFL mobilised transferred greater trochanter in order reproduce normal force vector medius minimus. Data was prospectively collected changes gait, strength, following patient reported outcomes (PROs): modified...
Purpose To compare the acetabular component size relative to patient's native femoral head between conventional THA (CTHA) approach and robotic-arm assisted (RTHA) infer which of these techniques preserved more bone. Methods Patients were included if they had primary osteoarthritis (OA) underwent total hip replacement June 2008 March 2014. excluded missing or rotated postoperative anteroposterior radiographs. RTHA patients matched a control group CTHA patients, in terms preoperative size,...
There is a paucity of literature regarding microfracture surgery in the hip. The purpose this study was to compare outcomes patients undergoing hip arthroscopy predominantly for labral tears with focal full thickness chondral damage on acetabulum or femoral head treated and matched control group that did not have damage. A prospective matched-control performed examining four patient-reported outcome (PRO) scores: modified Harris Hip Score (mHHS), non-arthritic score, Outcome Score-Activities...
There are limited studies on the effect of mild osteoarthritis (OA) outcomes hip arthroscopic surgery.To conduct a matched-pair analysis with minimum 2-year follow-up to evaluate after surgery in patients Tönnis grade 1 OA.Cohort study; Level evidence, 3.Data were prospectively collected who underwent between April 2008 and December 2012. Patients excluded if they had previous conditions. The remaining divided into either 0 or OA groups matched 1-to-1 ratio according age within 5 years, sex,...
Background: Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is example abnormality requiring correction a technically challenging access point. Purpose: To report on patterns clinical presentation intra-articular derangements, radiological associations, minimum 2-year outcomes after patients lateral...
