PURPOSE: To perform a systematic review of randomized controlled trials comparing clinical outcomes of rotator cuff repair with and without patch augmentation. METHODS: A systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by searching PubMed, the Cochrane Library, and Embase to identify randomized controlled trials which directly compared outcomes between rotator cuff repair (RCR) with versus without patch augmentation...

PURPOSE: To analyze the effect of the arthroscopic meniscal procedure in adult discoid lateral meniscus (DLM) according to the age and meniscal preservation by making comparisons with the non-discoid lateral meniscus (N-DLM). METHODS: From March 2014 to October 2020, comparative analysis was performed in adult DLM who underwent arthroscopic meniscal procedures (Operative DLM:134 knees), non-operative treatment (Non-operative DLM: 56 knees), and adult N-DLM who underwent arthroscopic meniscal procedures (Operative N-DLM: 64 knees)...

PURPOSE: This study aims to report the clinical outcomes, radiological evolution and survivorship of a series of patients affected by the post meniscectomy syndrome and treated with a polyurethane scaffold at a minimum 10-year follow-up. In addition, the radiological evolution of these patients was also assessed. METHODS: All the patients operated on a polyurethane meniscal scaffold implantation to treat a post-meniscectomy syndrome from 2008 to 2011 were prospectively followed...

PURPOSE: 1) To study the prevalence and quality of application of minimal clinically important difference (MCID), substantial clinical benefit (SCB), patient acceptable symptomatic state (PASS), and maximum outcome improvement (MOI), reported in orthopaedic sports medicine knee and shoulder literature in recent years. 2) To bring awareness of proper utilization of such metrics. METHODS: A literature review of all shoulder and knee articles published from the American Journal of Sports Medicine (AJSM), Journal of Shoulder and Elbow Surgery (JSES), and Arthroscopy from 2016-2020 was performed, specifically investigating if MCID, SCB, PASS, or MOI, were used or reported...

PURPOSE: To compare clinical outcomes, rate of return to sports, and psychological readiness among patients undergoing ACL reconstruction (ACLR) with and without concomitant Segond fracture. METHODS: We retrospectively identified patients who underwent primary ACLR from January 2012 to December 2020 with minimum 2-year follow-up. Exclusion criteria were additional ligamentous injury, age <16, or a concomitant lateral augmentation procedure. Preoperative knee radiographs were reviewed to identify Segond fractures...

PURPOSE: The purpose of this study was to 1) evaluate long-term patient reported outcomes and achievement rates of patient acceptable symptomatic state (PASS) in young athletes undergoing hip arthroscopy, and 2) report long-term sports continuance and reoperation. METHODS: Inclusion criteria consisted of age <24 years at surgery, femoroacetabular impingement undergoing primary hip arthroscopy with labral repair, and participation in sport with intent to return to sport after surgery...

PURPOSE: The purpose of this study was to compare hip survivorship and patient-reported outcomes after primary hip arthroscopy for femoroacetabular impingement syndrome (FAIS) in patients with versus without comorbid borderline hip dysplasia (BHD) at two-year follow-up. METHODS: A retrospective matched-cohort study was conducted involving patients who underwent primary hip arthroscopy for FAIS with a single surgeon from 2010-2019. BHD was defined as lateral center edge angle (LCEA) of 20-25°...

PURPOSE: The purpose of this study was to compare the clinical outcomes and tendon integrity after rotator cuff repair combined with anterior cable reconstruction (ACR) using the proximal biceps tendon and patch augmentation (PA) using a human dermal allograft (HDA) in a large retracted anterior rotator cuff tear. METHODS: Patients who underwent arthroscopic rotator cuff repair with two different augmentation procedures between January 2017 and December 2020 were enrolled...

PURPOSE: To analyze the effects of surgeon-specific factors, including case volume, career duration, fellowship training, practice type, and region of practice, on rates of two-year revision surgery, conversion to total hip arthroplasty (THA), and 90-day hospitalizations following hip arthroscopy. METHODS: The PearlDiver Mariner Database was used to query patients undergoing hip arthroscopy between 2015 and 2018. Surgeons performing these procedures were identified and surgeon-specific demographics and variables were collected from publicly available data...

PURPOSE: This study aimed to compare clinical and radiographic outcomes of medial patellofemoral ligament reconstruction (MPFL-R) and medial patellofemoral complex reconstruction (MPFC-R) for recurrent patellar dislocation.
