Study Design: A consensus statement.

Influence of Sudden Changes in Foot Strikes on Loading Rate Variability in Runners.

Foot strike patterns influence vertical loading rates during running. Running retraining interventions often include switching to a new foot strike pattern. Sudden changes in the foot strike pattern may be uncomfortable and may lead to higher step-to-step variability.

Enhancing meniscal repair with tough adhesive puncture sealing (TAPS) suture: A proof-of-concept study on bovine cadaveric knees.

Purpose: The objective was to use cyclic tensile loading to compare the gap formation at suture site of three different suture materials to repair bovine radial meniscal tears: (1) polyglactin sutures, (2) tough adhesive puncture sealing (TAPS) sutures and (3) ultra-high molecular weight polyethylene (UHMWPE) sutures.

Methods: Twelve ex vivo bovine knees were dissected to retrieve the menisci. Complete radial tears were performed on 24 menisci, which were then separated into three groups and repaired using either pristine 2-0 polyglactin sutures, TAPS sutures (2-0 polyglactin sutures coated with adhesive chitosan/alginate hydrogels) or 2-0 UHMWPE sutures with a single stitch.

Finite element analysis of distraction osteogenesis with a new extramedullary internal distractor.

Distraction osteogenesis (DO) is a bone regenerative maneuver, which is conventionally done with external fixators and, more recently, with telescopic intramedullary nails. Despite the proven effectiveness, external approaches are intrusive to the patient's life while intramedullary nailing damages the growth plates, making them unsuitable for pediatric patients. An internal DO plate fixator (IDOPF) was developed for pediatric patients to address these limitations.

Characteristics and Outcomes of Operatively Treated Discoid Lateral Meniscus in Pediatric and Young Adult Patients: A Multicenter Study.

Background: Discoid lateral meniscus (DLM) is the most common congenital abnormality of the meniscus. Tears are common; treatment is frequently not definitive, often requiring reoperation.

Purpose: To report the clinical manifestations, physical characteristics, operative treatments and findings, complications, and reoperations of DLM in pediatric patients from multiple centers across North America.

Emerging biologic augmentation strategies for meniscal repair: a systematic review.

Background: Meniscal repair should be the gold standard. However, the meniscus is poorly vascularized and even an excellent meniscus repair may not heal. Therefore, numerous studies and systematic reviews have been carried out on platelet-rich plasma (PRP), mesenchymal stem cells (MSCs) and fibrin clots for meniscal augmentation, but the results remain controversial.

A modified position for optimized skeletal maturity assessment of AIS patients and its impact on 3D spinal and pelvic parameters.

Purpose: A hands-on-wall (HOW) position for low-dose stereoradiography of adolescent idiopathic scoliosis (AIS) patients would allow for skeletal maturity assessment of the hand and wrist. Our aims were twofold: confirm the reliability and validity of skeletal maturity assessment using the HOW radiographs and compare the spinal and pelvic 3D parameters to those of standard hands-on-cheeks (HOC) stereoradiographs.

Methods: Seventy AIS patients underwent two successive stereoradiographs and a standard hand and wrist radiograph on the same day.

Flatfoot arch correction with generic 3D-printed orthoses at different body weight percentages.

Background: Flatfoot can be associated with foot pathologies and treated conservatively with foot orthoses to correct arch collapse and alleviate painful symptoms. Recently, 3D printing has become more popular and is widely used for medical device manufacturing, such as orthoses. This study aims at quantifying the effect of generic 3D-printed foot orthoses on flatfoot arch correction under different static loading conditions.

Retroarticular drilling for osteochondritis dissecans of the talus: A systematic review.

Background: Opinions differ on the optimal treatment for stable talar osteochondritis dissecans (OCD) with intact cartilage. Some recommend conservative management, while others prefer surgical care, which includes debridement and micro-fractures, transarticular drilling through a direct or medial malleolus approach and retroarticular drilling. The rationale behind retroarticular drilling is to induce bone marrow healing without touching the intact cartilage.

A tough gel coating technology has been developed to modify and functionalize sutures, but its effects on suture degradation remain unexplored. Our aim is to investigate how a tough gel coating mediates the properties of the suture.

Subchondroplasty in the treatment of bone Marrow lesion in early Knee Osteoarthritis: A systematic review of clinical and radiological outcomes.

Background: Knee osteoarthritis (KOA) is increasingly prevalent in North American society. The significant societal burden it represents makes it essential to promote and target new treatments in earlier phases of the disease. Among others, subchondroplasty is a newly documented technique using calcium phosphate injection targeting the osteochondral lesions preceding KOA, also known as Bone Marrow Lesions (BMLs).

Meniscus Repair in Pediatric Athletes.

Meniscus tears are common in the pediatric population, typically occur after noncontact injuries, and can be diagnosed clinically with MRI confirmation. Surgery should be offered to patients with loss of range of motion, persistent symptoms, or displaced/complex tears. Given poor long-term outcomes reported after meniscectomy, repair should be attempted when possible as pediatric menisci are well vascularized and have better outcomes after repair than their adult counterparts.

Advanced practice physiotherapy in paediatrics: Implementation results.

Objectives: This study aimed to evaluate the implementation of an advanced practice physiotherapist (APP) clinic in our paediatric institution and assess APP and orthopaedic surgeon satisfaction.

Methods: In this retrospective cohort study, all patient records from the APP clinic's second year (March 2017 to March 2018) at CHU Sainte-Justine were reviewed. These were compared with the records of patients seen by orthopaedic surgeons within the gait clinic the year before implementing the clinic.
