BACKGROUND: Valgus bracing in medial knee osteoarthritis aims to improve gait function by reducing the loading of the medial compartment. Orthosis composition and optimal adjustment is essential to achieve biomechanical and clinical effectiveness. OBJECTIVES: To investigate biomechanical functionality during gait, pain relief and compliance in patients with knee osteoarthritis using a lightweight adjustable knee unloader orthosis. STUDY DESIGN: Prospective observational clinical trial...

Osteochondritis dissecans (OCD) has been known for more than 100 years. Several reasons have been suggested as the major cause for developing OCD: trauma/microtrauma, ischaemic or genetic reasons. OCD is primarily located in the knee. In adolescent patients with knee symptoms, X-ray of the affected knee and often a subsequent MRI scan is indicated. Depending on the findings, an arthroscopy can be performed. Conservative treatment can be quiet regime or bracing. Operative treatment can be transchondral/retrograde drilling for the in situ lesion or fixation of the unstable lesion...

Skiing and snowboarding have increased in popularity since the 1960s. Both sports are responsible for a substantial number of musculoskeletal injuries treated annually by orthopaedic surgeons. Specific injury patterns and mechanisms associated with skiing and snowboarding have been identified. No anatomic location is exempt from injury, including the head, spine, pelvis, and upper and lower extremities. In these sports, characteristic injury mechanisms often are related to the position of the limbs during injury, the athlete's expertise level, and equipment design...

BACKGROUND: We aimed to (i) evaluate the immediate effect of a soft knee brace on pain, activity limitations, self-reported knee instability, and self-reported knee confidence, and (ii) to assess the difference in effect between a non-tight and a tight soft brace in patients with knee osteoarthritis (OA). METHODS: Forty-four patients with knee OA and self-reported knee instability participated in the single-session, laboratory, experimental study. A within-subject design was used, comparing a soft brace with no brace, and comparing a non-tight with a tight soft brace...

PURPOSE: The effectiveness of ACL functional knee braces to reduce meniscal and ACL strain after ACL injury or reconstruction is not well understood. A new dynamic knee tensioning brace system has been designed to apply an active stabilizing force to the knee. The ability of this system to reduce tissue strains is unknown. The purpose of this study was to test the ability of the dynamically tensioned brace to reduce strain in both the ACL and meniscus during rehabilitation activities...

Paediatric fractures of the tibial spine are relatively rare and controversy remains around how these injuries are best managed (Gans et al., 2014; Hargrove et al., 2004). Consequently most non-specialised paediatric units have limited experience of managing these injuries. This study aims to review the management and outcomes of isolated paediatric tibial spine fractures in a tertiary paediatric orthopaedic centre between 2008 and 2016. Data were collected on patient demographics, mechanism of injury, imaging, Meyers and McKeever grade of injury (Meyers and McKeever), management and outcomes, including Cincinnati and Lysholm-Tegner knee scores at a mean of 36 months post-operatively...

: Stable ankle injuries are highly prevalent in Emergency Departments across the UK. Appropriate management to enable patients to experience a smooth recovery and prevent chronic ankle instability or reoccurrence is a priority. Current literature states that stable ankle fractures and severe ankle sprains can be successfully managed with the below knee plaster or the aircast brace and crutches. The functional brace has proved to be clinically effective in several reports. There has however, been no research to measure patient satisfaction levels between these two treatments...

Introduction: Ponseti method has become the main treatment modality for the management of clubfoot producing good long-term results. However, variation in cast application post tenotomy has not been evaluated. Methods: A prospective cohort study involving 40 patients with 67 clubfeet were randomized into two groups: 32 above knee cast (AKC) and 35 below knee cast (BKC) after percutaneous tenotomy. All had foot abduction brace after post tenotomy cast. The median age was 21 weeks (range: 1-104 weeks) and 1...

Knee osteoarthritis that prevalently occurs at the medial compartment is a progressive chronic disorder affecting the articular cartilage of the knee joint, and lead to loss of joint functionality. Valgus braces have been used as a treatment procedure to unload the medial compartment for patients with medial osteoarthritis. Valgus braces through the application of counteracting external valgus moment shift the load from medial compartment towards the lateral compartment. Previous biomechanical studies focused only on the changes in varus moments before and after wearing the brace...

Osteoarthritis progression can be related to the external knee adduction and flexion moments during walking. Lateral foot wedges and knee braces have been used as treatment for osteoarthritis, but little is known about their influence on knee joint moments generated in the sagittal and frontal planes. Therefore, the aim of the present study was determine the effects of the isolated and combined use of valgus knee brace and lateral wedge foot orthotic on peak forces and moments during gait in knee osteoarthritis patients...

Brian B Gilmer
Posterolateral corner avulsion fractures are a rare variant of ligamentous knee injury primarily described in the skeletally immature population. Injury is often related to a direct varus moment placed on the knee during sporting activities. Various treatment strategies have been discussed ranging from nonoperative management, to excision of the bony fragment, to primary repair with screws or suture. The described technique is a means for achieving fixation of the bony avulsion using principles familiar to double-row transosseous equivalent rotator cuff repair...

The use of knee braces is common, and there is an abundance of different brace types available both "over the counter" and as "prescription devices". The braces are used for a range of knee problems ranging from minor knee discomfort to post-surgical rehabilitation. The available evidence is generally in favour of brace applications although the amount and quality of evidence is moderate to low with a positive benefit-harm balance. However, braces should generally not be used as a stand-alone or primary treatment strategy, but can be used as a potentially beneficial supplement to patients with knee disorders if needed...

We hypothesized that constant compression of the knee would mobilize residual synovial fluid and promote successful arthrocentesis. Two hundred and ten knees with grade II-III osteoarthritis were included in this paired design study: (1) conventional arthrocentesis was performed with manual compression and success and volume (milliliters) determined; and (2) the intra-articular needle was left in place, and a circumferential elastomeric brace was tightened on the knee to provide constant compression. Arthrocentesis was attempted again and additional fluid volume was determined...

OBJECTIVE: No randomized controlled trial (RCT) has compared the high tibial osteotomy (HTO) with non-surgical treatment in patients with medial knee osteoarthritis (OA) and varus malalignment. The aim was to compare the effectiveness of an unloader brace treatment or a usual care program to the HTO regarding pain severity and knee function. DESIGN: Surgical treatment (HTO) to two non-surgical options was compared by combining the data of two RCTs. One RCT (n = 117) compared an unloader brace to usual care treatment; the other RCT (n = 92) compared closing to opening wedge HTO...

Patellar tendon rupture in children is especially rare. The fact that the area of traumatic rupture has wide variations makes surgical treatment difficult. We present an 11-year-old boy with acute traumatic patellar tendon rupture at the tibial tuberosity attachment without avulsion fracture. Primary end-to-end repair and reinforcement using 1.5 mm stainless steel wires as a surgical strategy were undertaken. Early range of motion began with a functional knee brace and the reinforced stainless wire was removed 3 months after surgery...

PURPOSE: The Ponseti method for treating clubfoot was introduced in Norway in 2003, and a cohort of children has been followed for 8 to 11 years. In a previous study, we found good results after follow-up of two to five years, with 3% rate of extensive surgery (posterior release or posteromedial release). During 8 to 11 years of follow-up, the rate of extensive surgery increased to 11%. The children had been treated with a bilateral brace or a unilateral brace. In this multicentre study we aimed to compare these two post-corrective treatment methods...

Ligaments within the human knee are commonly torn or injured as a result of sports that involve sharp direction changes, pivoting and landing. For this reason, athletes are often side-lined from their respective sports for up to 18 months after injury to rehabilitate. As part of the rehabilitation process, knee braces are often prescribed in an attempt to decrease the recovery period of the injured individual by restraining and minimizing the motion at the knee. However, the true efficacy of knee bracing is yet to be fully evaluated as studies show mixed results to whether braces actually decrease the rehabilitation period for patients...

BACKGROUND: Wearable sensors gather data that machine-learning models can convert into an identification of physical activities, a clinically relevant outcome measure. However, when individuals with disabilities upgrade to a new walking assistive device, their gait patterns can change, which could affect the accuracy of activity recognition. OBJECTIVE: The objective of this study was to assess whether we need to train an activity recognition model with labeled data from activities performed with the new assistive device, rather than data from the original device or from healthy individuals...

BACKGROUND: Braces are used to treat pain in patellofemoral joint osteoarthritis (PFJOA). In a trial, we previously reported pain improvement after 6-weeks brace use. The pain reduction did not correlate with changes in Magnetic Resonance Imaging (MRI) assessed Bone Marrow Lesion volume or static synovial volume. Studies show that changes in the synovium on dynamic contrast enhanced (DCE) MRI are more closely associated with symptom change than static synovial volume changes. We hypothesised change in synovitis assessed using dynamic imaging could explain the reduction in pain...
