No clinical superiority of bi-cruciate retaining versus posterior stabilized total knee arthroplasty at two years follow-up.

The purpose of the present study was to evaluate and compare the clinical outcomes of two groups of patients subject to bi-cruciate retaining (BCR) or posterior-stabilized (PS) implants. It was hypothesized that patients treated with BCR prostheses would present higher flexion and better clinical and functional results than those treated with PS implants. This prospective study included thirty-two patients treated for primary knee osteoarthritis and assigned to two matched groups for their demographic characteristics and comorbidities.

Survivorship and complications of cementless compared to cemented posterior-stabilized total knee arthroplasties: A systematic review and meta-analysis.

Purpose: Controversy exists on the best fixation for total knee arthroplasty (TKA). Non-cemented fixation has been theorized to improve patient outcomes and longevity of implantation but no study has focused on comparison between cemented or cementless posterior-stabilized implants despite being the most commonly or second most frequently utilized implant in most total knee replacement registries.

Methods: Inclusion criteria with observational and interventional papers, and review articles that focused on patients with cementless and cemented PS TKAs were used to analyze outcomes such as implant survivorship, complication, or revision rates.

Mesenchymal Stem Cell Therapy for Bone Repair of Human Hip Osteonecrosis with Bilateral Match-Control Evaluation: Impact of Tissue Source, Cell Count, Disease Stage, and Volume Size on 908 Hips.

We investigated the impact of mesenchymal stem cell (MSC) therapy on treating bilateral human hip osteonecrosis, analyzing 908 cases. This study assesses factors such as tissue source and cell count, comparing core decompression with various cell therapies. This research emphasizes bone repair according to pre-treatment conditions and the specificities of cell therapy in osteonecrosis repair, indicating a potential for improved bone repair strategies in hips without femoral head collapse.

Proximal Tibiofibular Synostosis: Report of 2 Cases and New Surgical Technique.

Proximal tibiofibular synostosis is a rare condition. It is often misdiagnosed or difficult to diagnose and its treatment is not widely known. There is no surgical procedure clearly reported in the literature.

Arthroscopy with partial meniscectomy for degenerative tear does not increase the risk of total knee arthroplasty at five year follow up; however, this population undergoes total knee arthroplasty with a lower threshold of osteoarthritis.

Purpose: Degenerative meniscus tears can cause discomfort in some patients, and when medical treatments fail to provide relief, arthroscopy may be considered before resorting to knee prosthesis. However, the benefits of arthroscopy over nonsurgical treatments in patients over 60 years old are limited, and the evidence regarding its overall efficiency and drawbacks remains scarce. Furthermore, there has been no investigation into whether those patients treated with partial meniscectomy, undergo the knee operation at an earlier stage of osteoarthritis.

Lateral meniscus with tears or with histologic calcification does not increase the risk of lateral osteoarthritis after medial unicompartmental arthroplasty.

Purpose: Meniscal tears or histological meniscal calcifications (in the absence of radiological chondrocalcinosis) are frequent in osteoarthritis. Whether lateral meniscal lesions influence clinical outcomes after medial unicompartmental knee arthroplasty (UKA) is unknown.

Methods: We analyzed 130 patients (130 knees) with medial unicompartmental knee arthroplasties between 2005 and 2015.

Satisfactory outcomes of patellar tendon reconstruction using achilles' tendon allograft with bone block after infected total knee arthroplasty.

Purpose: Extensor mechanism disruption is an uncommon and devastating complication after total knee arthroplasty. It negatively affects patients' quality of life and leads to significant functional limitations and the inability to stand and walk. The purpose of the present study was to evaluate the outcomes of the extensor mechanism reconstruction using Achilles' tendon allograft after infected total knee arthroplasty.

Bone conductivity and spine fluoroscopy, Hand-Eye-Ear dialogue, during pedicle screw positioning: a new human cognitive system for precision and radiation-decrease; better than artificial intelligence and machine learning system?

Purpose: There is an increasing need for pedicle screw positioning while decreasing radiation exposure. This study compares intra-operative radiation dose using posterior internal fixation using impedancemetry-guided pedicle positioning by the Pediguard system versus standard free-hand sighting when surgery was performed with a trainee or expert surgeon.

Material And Methods: Using the electrical properties of bone, the Pediguard detects iatrogenic penetration of the pedicle wall and gives auditory feedback to the surgeon.

Hip fractures re-operation compared with death at two year in elderly patients: lowest risk of revision with dual mobility total hip arthroplasty than with bipolar hemiarthroplasty or internal fixation of Garden I and II.

Purpose: This study determined at two year follow-up the lifetime risk of re-operation for elderly patients with hip fractures undergoing internal fixation, dual mobility total hip arthroplasty, or bipolar hemiarthroplasty, using death of the patient as a competing risk.

Materials And Methods: With the hypothesis that arthroplasties may have less complications without increasing mortality even for Garden I and Garden II fractures, we retrospectively reviewed 317 hips with femoral neck fractures operated between January 2015 and August 2019. The mean age at time of surgical intervention was 82.

Endoscopic fascia lata release for treatment of gluteal tendinopathy: a prospective study with a follow-up of 6 months to 1 year.

Greater trochanteric pain syndrome (GTPS) is clinically defined as greater trochanter pain with mechanical characteristics. The most common diagnosis is gluteal tendinopathy. Most cases of gluteal tendinopathy resolve with conservative management.

Subtalar axis determined by combining digital twins and artificial intelligence: influence of the orientation of this axis for hindfoot compensation of varus and valgus knees.

Purpose: Previous studies evaluating hindfoot and knee alignment have suggested compensation between the knee and the hindfoot deformities. However, these studies did not investigate the influence of the orientation of the subtalar axis on the results.

Material And Methods: Using computed tomography data of patients without osteoarthritis, digital twins, and artificial intelligence, we identified the orientation of the axis of the subtalar joint.

Nonoperative and Operative Bone and Cartilage Regeneration and Orthopaedic Biologics of the Hip: An Orthoregeneration Network (ON) Foundation Hip Review.

Orthoregeneration is defined as a solution for orthopaedic conditions that harnesses the benefits of biology to improve healing, reduce pain, improve function, and, optimally, provide an environment for tissue regeneration. Options include drugs, surgical intervention, scaffolds, biologics as a product of cells, and physical and electromagnetic stimuli. The goal of regenerative medicine is to enhance the healing of tissue after musculoskeletal injuries as both isolated treatment and adjunct to surgical management, using novel therapies to improve recovery and outcomes.

Percutaneous plantar fasciotomy: radiological evolution of medial longitudinal arch and clinical results after one year.

Purpose: Plantar fasciitis (PF) is the most common cause of plantar heel pain. Conservative treatment and corrections of risks factors are the first line of care. For the 10% of patients who do not respond to conservative treatment, surgical release can offer relief of symptoms.

Digital twins, artificial intelligence, and machine learning technology to identify a real personalized motion axis of the tibiotalar joint for robotics in total ankle arthroplasty.

Purpose: Axial alignment of the talar implant in total ankle arthroplasty remains a major issue, since the real axis of motion of each patient is impossible to determine with usual techniques. Further knowledge regarding individual axis of motion of the ankle is therefore needed.

Material And Methods: Therefore, digital twins, artificial intelligence, and machine learning technology were used to identify a real personalized motion axis of the tibiotalar joint.

Mesenchymal stem cell therapy improved outcome of early post-traumatic shoulder osteonecrosis: a prospective randomized clinical study of fifty patients with over ten year follow-up.

Purpose: Post-traumatic osteonecrosis of the humeral head has a risk of progression to collapse in absence of treatment. The purpose of this study was to evaluate the results of mesenchymal stem cell grafting of the pre-collapse humeral head (study group) in adult patients with osteonecrosis and to compare the results with a simple core decompression without cells (control group). Patients After inclusion and randomization of 50 patients, 26 patients were enrolled in a single-blinded study for the cell therapy group.

Vitamin C prevention of complex regional pain syndrome after foot and ankle surgery: a prospective randomized study of three hundred and twenty nine patients.

Purpose: Complex regional pain syndrome (CRPS) after foot and ankle surgery has a significant impact on the ability to walk. As the symptomatic treatment of this disaster complication is poor and has low efficacy, a preventive treatment would be beneficial. Vitamin C has been reported to be efficient in preventing CRPS in elective scheduled surgery.

Role of Matrix-Associated Autologous Chondrocyte Implantation with Spheroids in the Treatment of Large Chondral Defects in the Knee: A Systematic Review.

Autologous chondrocyte implantation (ACI) is a cell therapy for the treatment of focal cartilage defects. The ACI product that is currently approved for use in the European Union (EU) consists of spheroids of autologous matrix-associated chondrocytes. These spheroids are spherical aggregates of ex vivo expanded human autologous chondrocytes and their self-synthesized extracellular matrix.

Role of Scaffolds, Subchondral, Intra-Articular Injections of Fresh Autologous Bone Marrow Concentrate Regenerative Cells in Treating Human Knee Cartilage Lesions: Different Approaches and Different Results.

The value of bone marrow aspirate concentrates for treatment of human knee cartilage lesions is unclear. Most of the studies were performed with intra-articular injections. However, subchondral bone plays an important role in the progression of osteoarthritis.

Surgical repair of a tibialis anterior tendon rupture : a case report.

A 61-year-old man who stretched in the morning presented a rupture of the tibialis anterior tendon treated by extensor hallucis longus transfer. Rupture of the tibialis anterior tendon is rare. Surgical treatment seems to be more efficient in improving the function.

Medieval surgery (eleventh-thirteenth century): barber surgeons and warfare surgeons in France.

Purpose: From the eleventh to the thirteenth century, three major events marked surgery in France: the appearance of an epidemic linked to ergotism which led to numerous amputations, the emergence of barber surgeons for civilian practice, and the organization of war surgery for the First Crusade.

Material And Methods: If a certain separation between medicine and surgery had appeared at the beginning of the Middle Ages, it would have been from 1215 (at the time of the Lateran Council) that the real separation between medicine and surgery was made. Before this date, the surgery was done by the clergy (monks) who had some experience of surgical practice.

The Dark Age of medieval surgery in France in the first part of Middle Age (500-1000): royal touch, wound suckers, bizarre medieval surgery, monk surgeons, Saint Healers, but foundation of the oldest worldwide still-operating hospital.

Purpose: During the Middle Ages, the Christian church established itself as the dominant force over all aspects of medieval life, including the practice of medicine. As the Church's influence expanded across Europe, the role of lay practitioners in medicine declined, and clerics gradually assumed the role of healers in surgical practice as the cure of the soul was felt to take precedence over cure of bodily ills.

Material And Methods: A retrospective analysis of hospital foundation, old-school surgical techniques still used today was performed during the first part of the Middle Age.

Cell therapy for posttraumatic shoulder osteonecrosis.

Purpose: This study compared the clinical and radiological results of bone marrow mesenchymal stem cell implantation with traditional simple core decompression (CD) using a matched pair case-control design for osteonecrosis of the humeral head (ONHH) after fracture of the proximal humerus.

Patients: We retrospectively reviewed 64 patients who had surgery for ONHH. Thirty patients had been treated with cell therapy between 2010 and October 2015, with 18 patients at pre-collapse stage (8 stages-I, 10 stages-II), and 12 patients at post-collapse stages (7 stages-III and 5 stages-IV).

Cell therapy for post-traumatic hip osteonecrosis in young patients.

Purpose: To investigate the effects of mesenchymal stem cells injections for treatment of post-traumatic osteonecrosis of the femoral head.

Methods: A total of 46 patients were eligible and enrolled in the study. Twenty-three patients were treated with cell therapy and 23 patients with hip arthroplasty (control group).

Computer Navigation Technique for Simultaneous Total Knee Arthroplasty and Opening Wedge High Tibial Osteotomy in Patients with Large Tibial Varus Deformity.

Introduction: Total knee arthroplasty (TKA) in patients with established knee osteoarthritis and major varus, mostly due to constitutional proximal deformity, remains a challenging procedure. Orthogonal cuts result in asymmetric bone resection and subsequent bone-related laxity or difficult release. A procedure that combines opening high tibial osteotomy (HTO) and TKA in the same sitting to address such major deformities is possible.
