The effectiveness of total hip arthroplasty (THA) for patients with no or minimal radiological signs of osteoarthritis (OA) is unclear. In this study, we aimed to: 1) assess the outcome of such patients; 2) identify patient comorbidities and CT or MRI findings which predicted outcome; and 3) compare their outcome to the expected outcome of THA for hip OA. Adult patients undergoing THA for hip pain, with no or minimal radiological features of OA (Tönnis grading scale ≤ 1), were identified from a consecutive series of 1,925 THAs. Exclusion criteria were: inflammatory arthritis; osteonecrosis of the femoral head; prior trauma or infection; and patients without minimum one-year follow-up and patient-reported outcome measures (PROMs). The primary outcome measure was the Oxford Hip Score (OHS). Secondary outcome measures were EuroQol-visual analogue scale (EQ-VAS), University of California and Los Angeles (UCLA) scale, and patient satisfaction on a validated three-point ‘better’, ‘same’, or ‘worse’ scale.Aims

Nonunion occurs when a fracture fails to heal permanently, often necessitating surgical intervention to stimulate the bone healing response. Current animal models of long-bone nonunion do not adequately replicate human pathological conditions. This study was intended as a preliminary investigation of a novel rat nonunion model using a two-stage surgical intervention, and to evaluate the efficacy of a selective prostaglandin E2 receptor 4 agonist (AKDS001) as a novel nonunion therapeutic agent compared with existing treatments. Initially, Sprague-Dawley rats underwent intramedullary Kirschner wire (K-wire) fixation of a femoral fracture with the interposition of a 2 mm-thick silicon disc. After three weeks, the silicon disc was removed, and the intramedullary K-wire was replaced with plate fixation while maintaining the 2 mm defect. Contrary to the control group (1) that received no treatment, the following therapeutic interventions were performed at injury sites after freshening: (2) freshening group: no grafting; (3) iliac bone (IB) group: IB grafting; (4) AKDS group: AKDS001-loaded microspheres (MS) combined with IB (0.75 mg/ml); and (5) bone morphogenetic protein (BMP) group: grafting of a BMP-2-loaded collagen sponge (10 μg; 0.10 mg/ml). After six weeks, micro-CT (μCT) and histological analysis was performed.Aims

The primary objective of this study was to compare short-term implant survival between cemented and cementless fixation for the mobile-bearing Oxford medial unicompartmental knee arthroplasty (UKA) across various age groups. The secondary objectives were to compare modes of failure and to evaluate patient-reported outcomes. A total of 25,762 patients, comprising 8,022 cemented (31.1%) and 17,740 cementless (68.9%) medial UKA cases, were included from the Dutch Arthroplasty Register. Patient stratification was performed based on age: < 50 years, 50 to 59 years, 60 to 69 years, and ≥ 70 years. Survival rates and hazard ratios were calculated. Modes of failure were described and postoperative change in baseline for the Oxford Knee Score and numerical rating scale for pain at six and 12 months’ follow-up were compared.Aims

Unicompartmental knee arthroplasty (UKA) is one option in the treatment of isolated unicompartmental advanced osteoarthritis (OA). While long-term results exist for medial mobile-bearing (MB) UKA, evidence regarding lateral MB-UKA is still limited. The Oxford Domed Lateral (ODL) implant aims to reduce the bearing dislocation rate in lateral MB-UKA through enhanced bearing entrapment. However, the long-term performance of this implant remains unclear. This study evaluated the long-term survival and clinical outcomes of the ODL in a non-designer centre. This single-centre retrospective analysis included 115 lateral MB-UKAs using the ODL performed between January 2006 and December 2014. The primary endpoint of the study was implant survival, defined as the time until a revision procedure was required for any reason. Secondary outcomes included Oxford Knee Score (OKS), Forgotten Joint Score (FJS), pain, satisfaction, and Tegner Activity Scale (TAS). Survival was assessed using Kaplan-Meier analysis.Aims

The use of arthroscopy of the hand and wrist has recently increased sharply in the elective setting and this, not surprisingly, has been followed by an increasing use in the trauma setting. Advocates for the use of arthroscopy in these patients cite the improved assessment of the displacement and reduction of fractures and the early diagnosis of associated injuries, while others temper this with concerns about increased operating time and possible complications. The data relating to patient-reported benefits and costs are limited. The aim of this review was to discuss the current available literature for the use of arthroscopy in the management of injuries of the hand and wrist. Cite this article:
Our aim was to investigate occurrence of senescent cells directly in tendon tissue biopsies from patients with chronic shoulder tendinopathies, and to correlate senescence with Enhancer of zeste 2 (EZH2) expression, the functional subunit of the epigenetic master regulator polycomb repressive complex. Human proximal long head of biceps tendons from patients with different chronic shoulder pathologies (n = 22), and controls from patients with humerus fracture (n = 6) and pathology (n = 4), were histologically scored for degeneration and analyzed for gene and protein expression of tendon specific factors, senescence markers, and EZH2. Tissues were further exposed to senotherapeutic compounds and the USA Food and Drugs Administration-approved selective EZH2 inhibitor EPZ-6438 and their senescence-associated secretory phenotype (SASP) assessed.Aims

Aims. The aim of the present study was to analyze the oncological and neurological outcome of patients undergoing interdisciplinary treatment for primary malignant bone and soft-tissue tumours of the spine within the last seven decades, and changes over time. Methods. We retrospectively analyzed our single-centre experience of prospectively collected data by querying our tumour registry (Medical University of Vienna). Therapeutic, pathological, and demographic variables were examined. Descriptive data are reported for the entire cohort. Kaplan-Meier analysis and multivariate Cox regression analysis were applied to evaluate survival rates and the influence of potential risk factors. Results. A total of 119 consecutive patients (mean age 38 years (SD 37; 1 to 83), mean follow-up 66 months (SD 26; 0 to 505) were investigated. Histological entities included Ewing’s sarcoma (EWS; 33), chondrosarcoma (CSA; 20), osteosarcoma (OSA; 22), and soft-tissue sarcoma (STS; 44). Surgery was performed in 88 patients (74%). Neurological parameters improved in 18 patients (20%) after surgery. Overall, 32 patients (36%) suffered from surgical complications requiring revision. The median survival was 42 months (IQR 10 to 204). The one-, five-, and ten-year survival rates were 73%, 47%, and 39%, respectively. Corresponding five-year survival rates for EWS, CSA, OSA, and STS were 63%, 61%, 40%, and 32%, respectively. The decade of diagnosis, histological entity, surgical intervention, resection margin, and the presence of metastases had significant influence on survival. (Neo-)adjuvant therapies alone had no significant influence on overall survival. Conclusion. Our study clearly demonstrates the positive impact of improved

The aim of this study was to report long-term clinical outcomes of a modern convertible metal-backed glenoid (MBG) in total shoulder arthroplasty (TSA). After a minimum of 15 years, a previously studied cohort of 35 patients who received a modern convertible MBG during the period 1996 to 2005 was contacted for clinical and radiological follow-up. At last follow-up, patients were evaluated radiologically and clinically according to the Constant Score, Simple Shoulder Test, and visual analogue scale for pain. Complications and revisions were recorded, and survival analysis was performed.Aims

Periacetabular osteotomy (PAO) is well established for acetabular reorientation and has shown successful improvement in patient-reported outcome measures (PROMs). Nevertheless, studies focusing on postoperative outcomes related to patient individual factors are still underrepresented. Therefore, this study aimed to analyze the functional outcome and activity level in relation to patient sex with a minimum follow-up of two years after PAO for mild to severe hip dysplasia. A single-centre study was conducted, enrolling patients undergoing PAO and completing a preoperative and postoperative radiological and clinical outcome assessment. The PROMs were assessed using the modified Harris Hip Score (mHHS), the Hip disability and Osteoarthritis Outcome Score (HOOS) with the subscales for pain, sport, activities of daily living (ADL), and quality of life (QoL), and the University of California, Los Angeles (UCLA) activity score. Kendall’s tau were calculated for correlation analyses.Aims

Hallux valgus (HV) presents as a common forefoot deformity that causes problems with pain, mobility, footwear, and quality of life. The most common open correction used in the UK is the Scarf and Akin osteotomy, which has good clinical and radiological outcomes and high levels of patient satisfaction when used to treat a varying degrees of deformity. However, there are concerns regarding recurrence rates and long-term outcomes. Minimally invasive or percutaneous surgery (MIS) has gained popularity, offering the potential for similar clinical and radiological outcomes with reduced postoperative pain and smaller scars. Despite this, MIS techniques vary widely, hindering comparison and standardization. This review evaluates the evidence for both open Scarf and Akin osteotomy and newer-generation MIS techniques. Fourth-generation MIS emphasizes multiplanar rotational deformity correction through stable fixation. While MIS techniques show promise, their evidence mainly comprises single-surgeon case series. Comparative studies between open and MIS techniques suggest similar clinical and radiological outcomes, although MIS may offer advantages in scar length and less early postoperative pain. MIS may afford superior correction in severe deformity and lower recurrence rates due to correcting the bony deformity rather than soft-tissue correction. Recurrence remains a challenge in HV surgery, necessitating long-term follow-up and standardized outcome measures for assessment. Any comparison between the techniques requires comparative studies. Surgeons must weigh the advantages and risks of both open and MIS approaches in collaboration with patients to determine the most suitable treatment. Cite this article:
