The inclusion criteria were: adult patients with diagnosed or high-risk of OSA undergoing ambulatory surgery; perioperative adverse events; control group included; general and/or regional anesthesia; and publication on/after February 1, 2011...

OBJECTIVE: to radiographically compare the effects of anchor positioning in the arthroscopic treatment of shoulder instability, in the 3- and 5-o'clock portals. METHODS: retrospective study of 36 patients, operated by two shoulder surgeons at the Unimed BH hospital, between January 2013 and January 2018. Each surgeon used only one of either the 3- or the 5-o'clock portal. After postoperative radiographs we performed angle comparisons between the greatest glenoidal axis, the angle of anchor insertion and distance from the inferior pole...

OBJECTIVES: This study aimed to introduce a novel arthroscopic treatment for medial and posteromedial instability of the knee and present the primary and follow-up results. METHODS: All patients who underwent the arthroscopic approach to treat medial and posteromedial corner instability from 2007 to 2017 were included in this report. Overall, 45 patients were included, among which 75.6% were male. The mean age of patients was 32.2 ± 8.4 years. Overall, 44.4% and 15...

The initial treatment of symptomatic disorders of the temporomandibular joint typically consists of a conservative approach, in which medication (painkillers and muscle relaxants), orofacial physiotherapy and splints are most important. In most cases, minimally invasive treatment options, such as arthrocentesis, arthroscopy or joint injections, are only considered when conservative methods provide insufficient symptom reduction. There is, however, an ongoing debate about the optimal treatment strategy due to an increasing body of evidence concerning the superior effectiveness in symptom reduction of minimally invasive treatment options with regard to conservative treatments...

OBJECTIVE: Nontraumatic osteonecrosis of the femoral head (ONFH) is commonly encountered in orthopedics. Without early clinical intervention, most patients with peri-collapse of the ONFH will develop femoral head necrosis and eventually require hip replacement surgery. The aim of this study is to evaluate clinical outcomes in patients with ONFH who underwent "light bulb" core decompression (CD) with arthroscopic assistance and to compare them with the outcomes of those treated with traditional procedures...

PURPOSE: Total knee arthroplasty (TKA) stands as a primary intervention for severe knee ailments, yet concerns remain regarding postoperative patient satisfaction and flexion instability. This study aims to evaluate the in-vivo kinematics of medial-pivot (MP) and posterior-stabilised (PS) designs during step-up activity, in comparison to the kinematics of the nonoperated contralateral knee. METHODS: Sixteen patients with PS-TKA and 14 with MP-TKA were retrospectively examined...

PURPOSE: An increased value of tibiofemoral rotation is frequently observed in patients with patellofemoral instability or maltracking. Nevertheless, the appropriate approach for addressing this parameter remains unclear so far. One potential approach for correcting tibiofemoral rotation is femoral rotational osteotomy. We hypothesized that femoral rotational osteotomy affects tibiofemoral rotation. METHODS: All patients who underwent femoral rotational osteotomy between January 2018 and May 2022 were included in this study...

PURPOSE: The purpose of this study was to compare micromotion of two new cementless tibial baseplates to a cementless design with well-published clinical success. METHODS: Three cementless tibial baseplate designs (fixed-bearing [FB] with keel and cruciform pegs, rotating-platform with porous central cone and pegs, FB with cruciform keel and scalloped pegs) were evaluated on sawbone models. Loading was applied to the baseplate at a rate of 1 Hz for 10,000 cycles, which represents 6-8 weeks of stair descent...

PURPOSE: The purpose of the study was to identify prognostic risk factors for prolonged opioid use at 2 and 6 weeks after hip arthroscopy using data from the Femoroacetabular Impingement RandomiSed controlled Trial and its external validation cohort study. METHODS: Opioids were prescribed for postoperative pain management at the surgeon's discretion, with a majority being prescribed a combination of oxycodone and paracetamol (5/325 mg). Prolonged opioid use was defined as the ongoing use of any dosage of opioids reported at either 2 or 6 weeks after surgery to treat femoroacetabular impingement, as recorded in the patient's study medication log...

PURPOSE: To investigate the 90° change of direction (COD) task in an extensive cohort of competitive healthy football players within the CUTtheACL study and to provide normative values and differences between males and females for full-body kinematics based on two-dimensional (2D) video analysis and scoring system. METHODS: One-thousand-and-two competitive football (soccer) players (age 16.3 ± 2.8 years, 264 females) were prospectively enroled...

BACKGROUND: The next-generation sequencing (NGS) has developed rapidly in the past decade and is becoming a promising diagnostic tool for periprosthetic infection (PJI). However, its diagnostic value for PJI is still uncertain. The purpose of this systematic review and meta-analysis was to evaluate the diagnostic value of NGS compared to culture. METHODS: In this systematic review and meta-analysis, electronic databases including PubMed, Embase, Cochrane Central Register of Controlled Trials, Web of Science and clinicaltrials...

PURPOSE: The aim of this systematic review was to identify the surgical indications of tibial derotational osteotomy (TDO) in patients with idiopathic external tibial torsion (ETT) and identify common measurement thresholds for surgical correction. METHODS: A systematic search of MEDLINE and Embase via Ovid, Cochrane Library via Wiley, Web of Science, Scopus, SPORTDiscus via EBSCOhost, ClinicalTrials.gov, WHO ICTRP and Global Index Medicus databases was performed with search terms reflecting the concepts of idiopathic tibial torsion, TDOs, and surgical indications...

PURPOSE: Preoperative prudent patient selection plays a crucial role in knee osteoarthritis management but faces challenges in appropriate referrals such as total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA) and nonoperative intervention. Deep learning (DL) techniques can build prediction models for treatment decision-making. The aim is to develop and evaluate a knee arthroplasty prediction pipeline using three-view X-rays to determine the suitable candidates for TKA, UKA or are not arthroplasty candidates...

Traumatic hip dislocation of a native hip joint represents an orthopaedic emergency that should be treated promptly. Dislocations can be classified based on the associated injuries and the direction of dislocation. Expeditious evaluation, reduction, and management of associated injuries are required to optimize short and long-term function of the hip. There are several important differences between the blood supply and ossification of the pediatric hip that necessitate different strategies for the evaluation and management of traumatic hip dislocations in pediatric patients...

BACKGROUND: Prior studies have demonstrated declining reimbursement and changing procedural utilization across multiple orthopedic subspecialties, yet a comprehensive examination of this has not been performed for rotator cuff repair, particularly at a geographic level. The purpose of this study was to evaluate changes in reimbursement, utilization, and patient populations for open and arthroscopic rotator cuff repairs (RCR) from 2013 to 2021 at a national and regional level. METHODS: The Medicare Physician and Other Practitioners database from years 2013 to 2021 were queried to extract all episodes of open chronic RCR, open acute RCR, and arthroscopic RCR...

CASES: Two competitive athletes with isolated comminuted trapezium fractures, sustained during American football and rugby, presented with pain and swelling of the first metacarpal base. Computed tomography confirmed isolated comminuted trapezium fractures. Arthroscopic reduction of displacement with screw fixation below the articular surface was performed through a small incision. Both patients returned to their preinjury sports levels within 2 months postoperatively. CONCLUSION: Arthroscopic treatment of isolated comminuted trapezium fractures achieved accurate reduction of articular surface displacement and preserved trapeziometacarpal joint stability with minimal soft-tissue invasion...

» Bony Bankart lesions are fractures of the anteroinferior glenoid rim, commonly associated with a traumatic anterior shoulder dislocation, and are diagnosed through radiological imaging and physical examination. Young male athletes playing contact sports are at highest risk of these injuries. Early diagnosis and treatment are crucial because, if left untreated, recurrent anterior shoulder instability and glenoid bone loss can occur. Both nonsurgical and surgical treatment options are available depending on the size of the lesion, with arthroscopic repair being the most common treatment method...

BACKGROUND: Arthroscopic superior capsule reconstruction (SCR) was developed to restore superior shoulder stability, muscle balance, and function after irreparable posterior-superior rotator cuff tears. The purpose of this study was to investigate whether favorable clinical outcomes after SCR for irreparable rotator cuff tears would be obtained in patients aged more than 70 years. METHODS: A total of 173 consecutive shoulders in 162 patients who underwent arthroscopic SCR using autografts of fascia lata for irreparable rotator cuff tears were allocated to 3 groups according to patient age at the time of surgery: Group 1, <55 years old (11 shoulders); Group 2, 55-70 years old (85 shoulders); and Group 3, > 70 years old (77 shoulders)...
