INTRODUCTION: Over the last years, the design of implants, the surgical approaches, and diagnostic tools changed in primary and revision of total hip arthroplasty. A knowledge of the different causes for revision after total hip arthroplasty is essential to avoid complications and failures. The purpose of this study was to determine trends of the etiology of implant failures over the last years by analyzing indications of revision hip arthroplasty. METHODS: All the patients who performed revision hip arthroplasties in our institution between 2001 and 2015 were reviewed retrospectively...

INTRODUCTION: The mechanical conflict in symptomatic femoroacetabular impingement can lead to early osteoarthritis. However, radiographic impingement morphology is often seen in asymptomatic individuals. Long-term observation regarding the risk of developing osteoarthritis in these individuals is lacking. Our study addressed the following questions: Does femoroacetabular impingement morphology increase the risk for development of osteoarthritis after at least 25 years? If yes, which radiographic parameter is the most predictive? Does the level of activity influence the risk for development of osteoarthritis? Are PROM influenced by the grade of osteoarthritis in this population? METHODS: We investigated 51 (32 male, 19 female) patients for whom AP pelvis and Dunn view radiographs were available with a minimum follow-up of 25 years...

INTRODUCTION: ACJ separation is a common shoulder injury. A variety of surgical techniques for high-grade ACJ separations have been described. A commonly used technique represents open reduction and fixation by a hook plate. Goal of the present study was to evaluate radiographic and functional outcome in patients with high-grade ACJ separations following surgical treatment with a hook plate before and after surgery as well as after hook plate removal. MATERIALS AND METHODS: Patients undergoing surgery with a hook plate due to traumatic ACJ separation between 2012 and 2014 were included and examined during a follow-up control...

PURPOSE: Coxarthrosis is a common disease of the adult hip joint. Elderly patients have mainly been treated with total hip arthroplasty (THA); however, younger patients are increasingly affected. Short-stem prostheses were developed for this special patient group. There have been few studies on the clinical outcomes of this type of prosthesis. This study compared the mid-term results of a short-stem prosthesis and a standard-stem prosthesis 8 years after implantation. METHODS: According to our clinical registry, patients who received a short-stem prosthesis before 2011 were identified...

BACKGROUND: Anterior knee pain (AKP) is a major complication that occurs after anterior cruciate ligament reconstruction (ACLR), even when hamstring tendon (HT) grafts are used. Damage to the infrapatellar fat pad (IPFP) during arthroscopy can cause AKP. The purpose of this study was to evaluate the influence of IPFP preservation on clinical outcomes, including AKP, in patients who underwent ACLR with HT autografts using the inside-out technique. METHODS: Forty-two patients who underwent primary ACLR with HT autografts were prospectively assessed for 2 years after surgery...

BACKGROUND: Total knee arthroplasty (TKA) is a successful procedure in managing end-stage arthritis when non-operative treatments fail. New technologies such as robotic TKA (rTKA) have been developed to improve the accuracy of prosthesis implantation. While short-term cohort studies on rTKA have shown excellent results, the evidence comparing between rTKA and conventional TKA (cTKA) is not yet well established. This meta-analysis aims to compare the efficacy and safety of rTKA versus cTKA in terms of clinical outcomes, radiographic results, complications, peri-operative parameters and costs...

BACKGROUND: The results of total hip arthroplasty (THA) with use of Delta ceramic articulation were successful at medium term follow-up. The use of this newest ceramic has markedly reduced the incidence of ceramic head fractures, but not the incidence of ceramic liner fractures. We tested a hypothesis that the ceramic fractures are prevented by use of a metal shell with 18° inner taper angle and a stem design with a reduced neck geometry. METHODS: We conducted a prospective multicenter study of cementless THA with use of 32/36-mm Delta ceramic bearing, Exceed ABT metal shell and Taperloc stem...

INTRODUCTION: Unicompartmental knee arthroplasty (UKA) is a well-accepted treatment for isolated unicompartmental osteoarthritis (OA) of the knee. In previous literature, it has been suggested that bi-unicompartmental knee arthroplasty (bi-UKA) which uses two UKA implants in both the medial and lateral compartments of the same knee is a feasible and viable option for the treatment of knee OA. Given the advantages of UKA treatment, it is warranted to review the literature of bi-UKA and discuss the evidence in terms of implant selection, indications, surgical techniques, and outcomes, respectively...

INTRODUCTION: Reverse shoulder arthroplasty (RSA) shows promising short- and mid-term results in cuff tear arthropathy. However, functional impairments are described in long-term findings. Micromorphological changes in the periarticular musculature could be in part responsible for this, but have not yet been analysed. Thus, histological changes of the deltoid muscle and their association to the functional outcome were evaluated in this study. MATERIAL AND METHODS: A total of 15 patients treated with RSA were included in this prospective study...

INTRODUCTION: Radiation-induced pathological fractures show high nonunion and infection rates. Successful treatment of postoperative infections of these fractures without limb amputation is extremely rare. METHODS: We report two cases of postoperative infection of pathological femoral fracture after radiation therapy for soft tissue tumors. Considering the poor condition of the irradiated site, a two-staged operation was selected to create the optimal situation for bone union...

INTRODUCTION: Bone-block procedures are well-established in anterior chronic shoulder instability treatment. Autograft with the coracoid process (Bristow-Latarjet procedures) and iliac crest (Eden-Hybbinette) are the most frequent source of bone but the use of allograft is also possible. The objective of this review is to assess clinical and radiographic outcomes after bony allograft reconstruction in anterior glenohumeral instability. MATERIAL AND METHODS: Medline, Cochrane, Embase databases were searched for studies reporting on bone allograft reconstruction in anterior glenohumeral instability with glenoid defect...

BACKGROUND: With the novel coronavirus-induced disease (COVID-19), there is the fear of nosocomial infections and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmissions to healthcare workers (HCW). We report the case of a 64-year-old male patient who underwent explantation of a shoulder prosthesis due to a periprosthetic infection. He was tested SARS-CoV-2 positive 7 days after admission to the orthopaedic department following strict infection control measures, routinely including screening all patients for multi-drug-resistant organism (MDRO) colonization upon admission...

INTRODUCTION: The third-generation Zweymüller hip endoprosthesis has been used for decades with excellent results in arthroplasty registries, but surgeon-stratified reports on this implant are still scarce. The aim of the presented single-hospital cohort analysis of the third-generation Endoplus-Zweymüller primary total hip arthroplasty was to determine implant survival rates until the first revision/removal at 10/15/20/25 years after implantation and to find out whether implant survival depended on the operating surgeon, patient's age and gender, operated side (right/left), season of the year and the set of implanted components (SL-PLUS femur, BICON-PLUS acetabulum or both components)...

BACKGROUND: Navigational techniques in orthopaedic trauma surgery have developed over the last years leaving the question of really improving quality of treatment. Especially in marginal surgical indications, their benefit has to be evident. The aim of this study was to compare reduction and screw position following 3D-navigated and conventional percutaneous screw fixation of acetabular fractures. The study hypothesis postulated that better fracture reduction and better screw position are obtained with 3D navigation...

INTRODUCTION: The Kocher approach is the workhorse approach to the lateral elbow. However, the exposure is often limited, particularly for open reduction. The purpose of this study is to quantitatively compare the articular exposure of the anconeus and Kocher approaches to the lateral elbow. METHODS: Eight surgical approaches (four Kocher and four Anconeus) were performed on four fresh cadavers. The right elbows of the first two specimens were dissected via the Kocher approach, and the left elbows via the anconeus approach...

INTRODUCTION: Although surgical fixation is routinely recommended for geriatric hip fractures, nonoperative treatment may be an option for certain stable fracture patterns. Occult hip fractures are nondisplaced fractures not evident on radiographs, but display intraosseous edema on MRI. Our aim is to report the rate of nonoperative treatment failure in patients with occult geriatric hip fractures. METHODS: All nonoperatively treated femoral neck or intertrochanteric femur fractures (AO/OTA 31A and 31B) from 2003 to 2018 were identified...
