Aims

Knee osteoarthritis (OA) is characterized by a chronic inflammatory process involving multiple cytokine pathways, leading to articular cartilage degeneration. Intra-articular therapies using pharmaceutical or autologous anti-inflammatory factors offer potential non-surgical treatment options. Autologous protein solution (APS) is one such product that uses the patient’s blood to produce a concentrate of cells and anti-inflammatory cytokines. This study evaluated the effect of a specific APS intra-articular injection (nSTRIDE) on patient-reported outcome measures compared to saline in moderate knee OA.

Periacetabular Osteotomy (PAO) has become the most important surgical procedure for patients with hip dysplasia, offering significant pain relief and improved joint function. This study focuses on recovery after PAO, specifically the return to sports (RTS) timeline, with the objective of identifying preoperative predictors to optimize patient outcomes. Our prospective, monocentric study from 2019 to 2023 included 698 hips from 606 patients undergoing PAO. Comprehensive preoperative data were collected, including demographic information, clinical assessments (Modified Harris Hip Score (mHHS), International Hip Outcome Tool-12 (iHot-12), Hip Disability and Osteoarthritis Outcome Score (HOOS), UCLA Activity Score) and psychological evaluations (Brief Symptom Inventory (BSI) and SF-36 Health Survey). Advanced logistic regression and machine learning techniques (R Core Team. (2016)) were employed to develop a predictive model. Multivariate regression analysis revealed that several preoperative factors significantly influenced the RTS timeline. These included gender, invasiveness of the surgical approach, preoperative UCLA Score, preoperative sports activity level, mHHS, and various HOOS subscales (Sport/Recreation, Symptoms, Pain) as well as psychological factors (BSI and SF-36). The subsequent model, using a decision tree approach, showed that the combination of a UCLA score greater than 3 (p<0.001), non-female gender (p=0.003), preoperative sports frequency not less than twice per week (p<0.001), participation in high-impact sports preoperatively (p=0.008), and a BSI anxiety score less than 2 (p<0.001) had the highest likelihood of early RTS with a probability of 71.4% at three months. Using a decision tree approach, this model provides a nuanced prediction of RTS after PAO, highlighting the synergy of physical, psychological, and lifestyle influences. By quantifying the impact of these variables, it provides clinicians with a valuable tool for predicting individual patient recovery trajectories, aiding in tailored rehabilitation planning and predicting postoperative satisfaction

Dislocation is still one of the more common reasons for revision of THR.Registry and large institutional data has demonstrated the effectiveness of Dual Mobility articulations in reducing revision for dislocation after THR. There is little data about whether the use of dual mobility is associated with a comprised clinical functional outcome. This study aimed to ascertain whether the use of Dual Mobility articulations (DM cups) comes within a compromise to the functional of the THR procedure as measured by the Hip disability and Osteoarthritis Outcome Score (HOOS). Utilising a retrospective design, patients were grouped into those with DM cups with 12 PROMs (Cohort 1) or a large data base of all THR procedures also with a complete set of 12 month PROMs (Cohort 2). The 2 groups were matched for age and gender through propensity score matching. The comparison focused on five domains of the HOOS: Pain, Symptoms, Activities of Daily Living (ADL), Sports and Recreation, and Quality of Life (QOL) at 6- and 12-months post-operation. 12 month PROM data suggested a convergence in scores for several domains, no uniform superiority of one articulation type over the other was found across all domains. These results suggest that both DM cup and standard articulations can effectively improve patient-reported outcomes in THR surgeries, but there are variations in recovery within each cohort that are potentially influenced by factors beyond the articulation type. This study contributes to the ongoing dialogue on optimising prosthetic selection to enhance recovery trajectories and quality of life for THR patients, emphasising the critical role of evidence-based decision-making in orthopaedic surgery

Introduction/Purpose. A randomized clinical trial of first MTP joint hemiarthroplasty with a synthetic cartilage implant demonstrated equivalent pain, function and safety outcomes to first MTP joint arthrodesis at 2 years. Recognizing that many hemiarthroplasty and total toe implants have initially good results that deteriorate over time, the purpose of this study was to prospectively assess the safety and efficacy outcomes for the synthetic cartilage implant population and to determine if the excellent outcomes were maintained at >5 years. Methods. One hundred nineteen patients were evaluated at 5+ years; 23 could not be reached for follow-up, but implant status was available for 7 of these subjects. Patients completed a pain visual analogue scale (VAS) and Foot and Ankle Ability Measure (FAAM) Sports and Activities of Daily Living (ADL) scores, preoperatively and at 2, 6, 12, 26, 52, 104 and 260 weeks postoperatively. Minimal clinically important differences are: ≥30% difference for pain VAS, 9 points for FAAM Sports, and 8 points for FAAM ADL. Great toe active dorsiflexion, weight-bearing radiographs, secondary procedures, and safety parameters were evaluated. Results. Of 119 patients available at mean 5.8 years follow-up (SD ±0.7; range: 4.4–8.0), 9 underwent implant removal and conversion to fusion in years 2–5, leaving 106 patients. The implant survival rate was 92.4% at 5.8 years. Pain and function outcomes at 5.8 years were similar to those at 2 years. VAS Pain, FAAM Sports, ADL Scores were maintained or improved at 5.8 years. No evidence of avascular necrosis, device migration or fragmentation was observed. There were no unanticipated safety events through 5.8 years. Ninety-three (93%) percent would have the procedure again. Conclusion. The synthetic cartilage hemiarthroplasty implant continues to demonstrate safety and efficacy for the treatment of advanced first MTP joint osteoarthritis with evidence of therapeutic effect and acceptable safety profile at 5.8 years

Introduction. Total ankle replacement as a valid treatment for end stage ankle arthritis, is gaining popularity and every year there is an increasing number of procedures. With revision rates as high as 21% at 5 years and 43% at 10 years there is a need for understanding and reporting the outcome of revision ankle replacement. Our aim was to study the patient reported outcomes following revision TAR with a minimum of 2 year follow up. Methods. All patients that underwent a revision total ankle replacement between 2012 and 2016 were included in the study. All patients received a post-operative questionnaire comprising of MOX-FQ score, EQ-5D (UK) and Foot and Ankle outcomes scores (FAOS) and patients satisfaction questionnaire with a minimum of 2 years follow up. Results. 33 patients had a revision total ankle replacement between 2012 and 2016. 2 patients were deceased therefore 31 patients were included in the study. 4 patients declined participation for completing questionnaires. We received 15/27 (55.5%) completed questionnaires. The mean MOX-FQ average domain score for pain was (50.6 ± 26.9), walking/standing (62.4 ± 36.5) and social function was (43.7± 31.0). The mean FAOS scores were (52.5 ± 30.6; pain), (54.5 ± 29.2; symptoms), (62.1 ± 30.5; ADL) and (35.5 ± 28.2; for quality of life). The mean overall health score today for EQ-5D was 73.9/100. 50% of patients were satisfied with the pain relief and return to sports and recreation obtained following the operation, 57% were satisfied with the improved in daily activities. 78.5% were overall satisfied with the results from surgery. Conclusion. Revision total ankle replacement gives overall satisfactory results demonstrated from patients reported outcomes at a minimum of 2 years following surgery

The aim of this study was to produce clinical consensus recommendations about the non-surgical treatment of children with Perthes’ disease. The recommendations are intended to support clinical practice in a condition for which there is no robust evidence to guide optimal care.

Introduction. Humans Functions (locomotion, protection of organs, reproduction) require a strong support system (bones). The ‘Osteostasis’ is the ability of maintaining the bone structure, its mechanical characteristics and function. Five principles are required for an efficient bone system:. Basic Requirements:. 1) Stability and 2) Function. Repair System (like house building in desert or sea):. 3) Roads (vessels), 4) Materials (calories, proteins), 5) Workers (bone cells). Analysis of bone problems through these principles bring to optimised treatments. Materials & Methods. Measurements (>700 lengthening, 32-year follow-up, Full WB Albizzia/G-Nails FWBAG): Bone-DEXA, WB conditions, muscle, fat, etc. Principle-1. Solid bone replacement with a 100% biocompatible and reliable FWBAG with sports (POD0). Principle-2. Bone, Muscle & neural integrity for function Principle-3. Vascular flow lesions induce non-healing (arteriography). Muscle activity accounts for 90% of bone blood flow, ×10 by sports. Required: Checks (arteriography) and treatments (training). Principle-4. Food (NRV Kcal × 2–3, 20–25% proteins). Principle-5. Maintain bone cells and increase them. Suppress ‘opening’, ‘venting’, ‘drainages’. Results. Principle1. Nail fracture (1.2%), nail dysfunction (0%) with FWBAG. Principle2. Intensive sports preop and from POD0 - Principle3. Increased preop vascular supply & muscle force, postop resistance sports fasten recovery. Wheel-chair or low activity decreases healing. Principle4. 6–9 cm circumference loss (non WB-nails or no proper training); 0 cm circumference loss (gain <10 cm) with intense resistance training + high calory intake. - Principle5. Bone cells preservation (no opening, IM saw, increasing bone cells) allow Healing Index down to 8D/cm. Conclusions. The ‘5P’ allow reaching treatment targets by optimisation of problem solving, maintaining Osteostasis. What would I like or tolerate for me? How can I reach it? Full WB and sports from POD0 was a target 38 years-ago, still not enforced by most of us. Resistance sports, high-calory intake suppress muscle loss and fasten healing, thanks to muscle blood flow and the ‘5P’
