The objective of this study was to determine whether there are significant differences in terms of indications, techniques, patient variables, and objective and subjective outcome scores as a function of the geographic locale of published studies of knee articular cartilage surgery./r/nAn […]

Published studies have reported many inconsistent results regarding the comparison of same-day discharge total joint arthroplasty (TJA) and inpatient TJA. More notably, many recent studies comparing same-day discharge TJA with fast-track TJA presented higher rates of complications for same-day […]

Dislocation remains a major complication in total hip arthroplasty (THA), in which femoral component orientation is considered a key parameter. New imaging modalities and definitions on femoral component orientation have been introduced, describing orientation in different planes. This study aims […]

Tibial tubercle osteotomy (TTO) is indicated to treat patellofemoral (PF) malalignment and chondral disease refractory to conservative treatment. However, there are no systematic reviews describing TTO outcomes in chondral damages without instability./r/nThe aims of this study were to (1) assess […]

Long-Term Survival of HINTEGRA Total Ankle Replacement in 683 Patients

The management of elbow fracture-dislocations is challenging. The internal joint stabiliser (IJS) (Skeletal Dynamics, Miami, FL) has been advocated as an alternative to traditional techniques. This article shares our initial clinical experience and provide a systematic review analysing the ability […]

The present study investigated the type of sport and activity level of athletes before they underwent knee and/or hip arthroplasty for osteoarthritis (OA), and compared them with a control group of subjects who did not undergo knee and hip arthroplasty. We hypothesed athletes exposed to high […]

During total knee arthroplasty (TKA), surgeons mobilize the patella to facilitate clear visualization of the articular surfaces and allow better prosthesis placement. According to the manipulation, this manipulation can be divided into patellar eversion and noneversion. However, the effect of […]

Unconstrained pyrocarbon and metal-on-polyethylene (MoP) proximal interphalangeal (PIP) joint arthroplasty is an increasingly popular alternative to silicone implants and arthrodesis. This systematic review appraises their outcomes. Thirty studies comprising 1,324 joints (813 pyrocarbon, 511 MoP) […]

Patients undergoing total knee arthroplasty (TKA) show postsurgical quadriceps weakness. Neuromuscular electrical stimulation (NMES) has been shown to be an effective treatment for muscle strength recovery in a number of orthopaedic conditions. The aim of this review is to investigate whether […]

Hallux rigidus is the most common arthritic condition of the foot. Interpositional arthroplasty (IPA) is indicated for advanced-stage hallux rigidus and attempts to maintain joint motion through insertion of a biologic spacer into the joint. However, the data evaluating the effectiveness of IPA are […]

The purpose of this study was to compare the union rates and clinical outcomes of 4-corner arthrodesis with different methods of osteosynthesis./r/nA systematic review of studies published in Ovid, Medline, Embase, and PubMed was conducted. Primary studies that reported clinical and radiographic […]

Eldecalcitol (ED-71) is a vitamin D analog for the treatment of osteoporosis. However, inconsistent results have been reported in this regard. Hence, this meta-analysis of randomized controlled trials (RCTs) aimed to assess the efficacy and safety of ED-71 for osteoporosis./r/nThe PubMed, Embase, […]

Bones are living organisms that build and break down, but when the body loses more bone than it makes, problems can arise. Early detection and treatment can help those with bone loss maintain active lifestyles.

Juvenile idiopathic arthritis (JIA) can lead to joint deformity and bone destruction, which can cause gait disturbances. To the best of our knowledge, there are no case reports with over 10 years of follow-up on quadruple joint arthroplasties (QJA) for bilateral hip and knee ankylosis associated […]

The management of elbow fracture-dislocations is challenging. The internal joint stabiliser (IJS) (Skeletal Dynamics, Miami, FL) has been advocated as an alternative to traditional techniques. This article shares our initial clinical experience and provide a systematic review analysing the ability […]

Dr. Prakash Jayabalan has long pondered why more non-operative treatment options aren't available to patients with knee osteoarthritis (OA), particularly because it is the most common cause of disability in the U.S.

Discovering that a well-supported, evidence-based virtual physical therapy program produces the same functional and patient-reported outcomes as outpatient physical therapy—even for ambulatory TKA procedures—is a game-changer. The rise in musculoskeletal care utilization is driving the […]

A team of researchers from Carnegie Mellon University (CMU) and the University of Connecticut (UConn) has 3D printed novel calcium phosphate graphene (CaPG) scaffolds that could be used for bone regeneration applications in the future. The team sought to develop an alternative to traditional […]

Lateralized reverse shoulder arthroplasty (RSA) has emerged as an attempt to improve on some of the drawbacks of conventional RSA, such as glenoid notching and decrease in ROM. Although this new design is being used in clinical practice, the evidence is mostly limited to case series and has not […]

The success of anterior cruciate ligament (ACL) reconstruction is influenced by effective rehabilitation. Previously published, comprehensive systematic reviews evaluating rehabilitation after ACL reconstruction have studied Level-I and II evidence published through 2012. Interval studies continue […]

Scaphoid Nonunion Repair with Vascularized Distal Radius Bone Graft

Ulnar-sided wrist pain is a common cause of debilitating wrist pain in stick-handling athletes. Due to the complexity of surrounding anatomy, the evaluation and diagnosis can be challenging./r/nInjury of the triangular fibrocartilage complex (TFCC) is the most common cause of ulnar-sided wrist […]

This article presents a systematic review of optical see-through head mounted display (OST-HMD) usage in augmented reality (AR) surgery applications from 2013 to 2020. Articles were categorised by: OST-HMD device, surgical speciality, surgical application context, visualisation content, […]

This paper systematically reviewed and assessed all retrievable pharmacoeconomic studies on denosumab for the treatment of osteoporosis. Denosumab was more cost-effective in patients with older age, prior fracture experience, lower BMD T-scores, and more risk factors. ESCEO-IOF guidelines were […]

To determine the complications from elbow arthroscopy for the past 16 years, and to summarize the most reported safety techniques and risk factors./r/nEligibility criteria included level I to IV evidence articles that were published after 2005 in the English language. Excluded were vet, […]

Pathology of the long head of the biceps tendon (LHBT) is a common disorder affecting muscle function and causing considerable pain for the patient. The literature on the two surgical treatment methods (tenotomy and tenodesis) is controversial; therefore, our aim was to compare the results of these […]

Acute arterial thrombosis after hip arthroplasty is a rare event associated with potentially catastrophic complications. Early clinical diagnosis of progressive limb ischemia is often difficult in the immediate postoperative period because of residual neuraxial blockade and the nonspecific […]

This is a case of a 14-year-old female athlete with cuboid syndrome who underwent calcaneocuboid ligament complex reconstruction using a palmaris tendon allograft that was passed through 2 parallel extra-articular dorsoplantar bone tunnels through the calcaneus and cuboid. She returned to […]

Osteoid osteomata comprise approximately 10% of benign bone tumours, with 20% of them being located in the proximal femur and 1-3% in the pelvis.
