BACKGROUND: Although previous studies have compared radiological, pain, and function scores in kinematically aligned (KA) and mechanically aligned (MA) total knee arthroplasty (TKA), no previous studies have undertaken a three-dimensional (3D) gait analysis in these groups. This study compared kinematic and kinetic variables recorded during level walking in patients at least 2 years post-surgery who underwent an MA or KA procedure. METHODS: Utilizing a 9-camera motion analysis system, gait analysis was undertaken on 29 patients (MA = 15, KA = 14)...

BACKGROUND: In total hip replacement (THR), it is essential to achieve a primary stability to guarantee good long-term results. A novel locking screw hip (LSH)-stem, anchored to the medial cortex of the proximal femur by 5 monocortical locking screws, was developed to overcome the shortcomings of uncemented press-fit and cemented straight stems while simultaneously achieving primary stability. The aim of this study was to investigate the biomechanical competence of the LSH-stem in comparison to an uncemented press-fit stem...

INTRODUCTION: Introduction of new surgical techniques is normal, but seldom monitored in real time. The purpose of this study was to monitor the learning curve when introducing a new surgical technique to a department. We did a prospective evaluation of the learning curve when introducing the minimally invasive direct anterior approach in total hip arthroplasty. We wish to investigate whether there is a learning curve for the direct anterior minimal invasive approach in total hip replacement and what are the early complications to this approach...

BACKGROUND: Custom triflange acetabular components are being increasingly used for the reconstruction of Paprosky type IIIB acetabular defects. However, midterm survivorship data are lacking. METHODS: We queried the prospective registries at 2 high-volume revision centers for patients who had undergone revision total hip arthroplasty using a custom triflange component between 2000 and 2011. We identified 73 patients with minimum 5-year follow-up. These patients' records were reviewed to determine incidence of revision or reoperation, clinical performance, and radiographic stability...

PURPOSE: In adults, growth hormone deficiency (GHD) has been associated with low bone mineral density (BMD), an effect counteracted by growth hormone (GH) replacement. Whether GH is beneficial in adults with age-related bone loss and without hypopituitarism is unclear. METHODS: We conducted a systematic literature search using Medline, Embase and the Cochrane Register of Controlled Trials. We extracted and analyzed data according to the bone outcome included [bone mineral content (BMC), BMD, and bone biomarker, fracture risk]...

OBJECTIVES: Correct positioning of the acetabular component is a key factor in minimizing the risk of dislocation after total hip replacement (THR) surgery. A "safe" orientation of the cup is usually defined by 2 angles measured between its geometric axis and the anterior pelvic plane. However, in the current state-of-the-art approach to THR surgery, the intraoperative orientation of the anterior pelvic plane cannot be measured. Even less is known about the functional orientation of the pelvis, which determines the postoperative orientation of the cup during the patient's everyday activities...

INTRODUCTION: Hip revision surgery is associated with a high probability of the necessity for a blood transfusion. Different studies support the use of tranexamic acid (TXA) to decrease the rate of transfusions in primary hip surgery. Nevertheless, the use of this drug in hip revision surgery has not yet been widely accepted. The aim of our study was to establish the rate of blood transfusion with and without TXA in hip revision surgery. METHODS: We retrospectively studied 125 hip revision surgery patients operated on between 2011 and 2014...

Displaced intracapsular femoral neck (AO type 31 B2/3) fractures have various treatments, including internal fixation (IF), unipolar uncemented hemiarthroplasty (HA), bipolar uncemented HA, unipolar cemented HA, bipolar cemented HA, uncemented total hip replacement (THR), and cemented THR. Systematic literature retrieval was performed from the databases to compare them in a network meta-analysis. Forty studies (85 arms) containing 6141 patients were included. Overall, our network meta-analysis rank the orders of 7 procedures in reoperation, mortality, dislocation and infection, which indicates that IF may provide the highest reoperation incidence, unipolar cemented HA may provide the lowest reoperation incidence; uncemented THR contributes the highest dislocation incidence; and bipolar uncemented HA provides the lowest infection incidence...

BACKGROUND: Patients presenting with cam deformity of the femoral head and neck sustain repeated trauma to the articular cartilage of the superior acetabulum, with chondral delamination injuries found during hip arthroscopy. Two previous studies reveal conflicting chondrocyte viability data in these traumatic cartilage injuries. The full-thickness nature of flaps may suggest that chondrocytes residing in the cartilage flap matrix in the joint environment would remain viable despite shear trauma...

PURPOSE: The fracture stage of non-traumatic osteonecrosis (ON stage 3) of the femoral head (ONFH) has an unfavourable prognosis frequently requiring total hip replacement (THR). The percentage could be lowered after core decompression. In earlier non-fracture ON stages, implantation of autologous bone marrow aspirate concentrate (BMAC) improved the effect of core decompression. The purpose was to evaluate the effect of BMAC in addition to core decompression in stage 3 ONFH. METHODS: A double blind RCT was conducted comparing two groups: core decompression plus saline injection or core decompression plus BMAC implantation...

Patient-reported outcome measures are a critical tool in evaluating the efficacy of orthopedic procedures. The intention of this study was to evaluate reliability, validity, responsiveness and minimally important change of the German version of the Hip dysfunction and osteoarthritis outcome score (HOOS). The German HOOS was investigated in 251 consecutive patients before and 6 months after total hip arthroplasty. All patients completed HOOS, Oxford-Hip Score, Short-Form (SF-36) and numeric scales for pain and disability...

Concomitant ipsilateral intracapsular and extracapsular fractures of the femoral neck are rare injuries with only 14 cases described in the literature as single case reports. We present three cases that were successfully and uniquely treated by uncemented hip arthroplasties. Two patients underwent complex primary uncemented total hip replacements, and one patient underwent an uncemented bipolar fluted stem hemiarthroplasty. The level of bearing constraint varied between implants. After describing our cases we review the literature and make recommendations on the management of these injuries...
