Filter by:The goal of this observational study is to assess the prevalence of radiographic knee osteoarthritis and to report medium and long term functional outcomes secondary to tibia plateau fractures. The second aim was to investigate whether there were any risk factors associated with these outcomes.
The anterior cruciate ligament (ACL) is the main stabilizer of the knee joint, as it controls anteroposterior and rotatory knee laxity. The number of ACL injuries has increased in the past three decades because more and more people participate in recreational and competitive sporting activities. Injury to the ACL often leads to functional instability, damage to the meniscus and articular cartilage, and an increased risk for osteoarthritis (OA). Emphasizes the fact that ACL has limited healing potential 'The gold standard' treatment is ACL reconstruction, with over 200,000 reconstruction surgeries performed annually in the United States. However, despite the success of surgery in restoring functional stability, it has been found so far in several studies that the prevalence of moderate to severe arthritis in long-term radiographic follow-up is more than 50% after ACL reconstruction within 5 to 15 years or sooner. ACL-injured knees had at least 3 times higher risk of arthritis than uninjured contralateral knees. Early osteoarthritis was observed on magnetic resonance imaging (MRI) up to 11 years following ACL injury after operative and nonoperative management. Because ACL injuries predominantly occur in individuals between the ages of 15 and 25 years, symptoms of OA most often affect patients during their most productive years. This is worrisome because most patients who sustain ACL tears are free of the risk of other factors for developing OA.Consequently, posttraumatic OA after ACL reconstruction ultimately translates into a large economic effect on the healthcare system owing to the young age of this population. Platelet-rich plasma is an autologous solution of highly concentrated platelets dispersed in a small capacity of plasma. Enthusiasm for the therapeutic potential of platelets is based on its rich omplement of anabolic growth factors and anti-inflammatory cytokines in the platelets, which induce cellular proliferation, migration, differentiation, angiogenesis, and extracellular matrix synthesis. In addition, the functional mechanisms of PRP in OA treatment have been explained by its effect on modulating critical pro-inflammatory mediators and catabolic enzymes, as well as maintaining joint homeostasis. The reasons for this early incidence of post-traumatic OA remain unclear, but the underlying mechanisms have been speculated to involve some combination of cartilage damage at the time of injury, and posttraumatic molecular changes in the joint, including immune reactions or persistent secondary inflammation. We hypothesized that PRP injection after ACL reconstruction could prevent cartilage damage, act anti-inflammatory, and provide better clinical and radiological outcomes seen in MRI.
Chondromalacia patella (CMP) is a common condition in patients presenting to healthcare units with anterior knee pain (1).
To our knowledge, no study has compared the difference between these two NA techniques. Early postoperative adverse events like uncontrolled pain, orthostatic hypotension, urinary retention, and prolonged motor block are linked to late patient mobilization, prolong hospitalization and failure to discharge in outpatient setting. The type of anesthesia used may have an important impact. Therefore, this study has the potential to improve the already established ERAS program and improve patients care perioperative and postoperative. Showing that SED-EA and SA are equivalent will allow for a more efficient and reliable technique for THA/TKA ERAS program that can be further translated into other lower limb surgeries.

Meniscal lesions are common in pediatrics and mainly affect adolescents. These lesions can jeopardize the functional prognosis of the knee in the short, medium or long term if they are not well managed. More precisely, it is a question of determining whether arthroscopic repair of isolated meniscal lesions in children gives good results and what factors influence them, with the aim of improving the care of children suffering from meniscal lesions. The treatment of meniscal lesions comes down to either conservative or restorative treatment or non-conservative treatment by meniscectomy. For most authors, the treatment of meniscal lesions must remain restorative through meniscal suture, leaving no room for meniscectomy. The open approach has given way to the arthroscopic approach which, according to the literature, is the gold standard. Meniscal lesions are varied and therefore there are numerous therapeutic procedures. Therapeutic indications are precise but the results of the treatments remain differently assessed depending on the studies; studies evaluating the results of treatment in the pediatric population are few in number. Based on this observation, the present study aims to describe the results of repairs of meniscal lesions in pediatric traumatology.
Background: Cruciate ligament tears are clinically diagnosed by detection of anterior or posterior tibial translation on physical examination; however, this manual method of assessment is imprecise, subjective, and not reproducible. Recently a new instrument, a stress radiographic device and knee stability test (DYNEELAX), were produced to objectively measure these displacements. Objective: To assess new diagnostic methods, in the measurement of anterior/posterior tibial translation in cruciate ligament-deficient knee compared to the healthy knee. Material and method: The MRI, stress radiographic device and knee stability test was applied to cruciate ligament-tear knees that were diagnosed by physical examination as having partial or complete cruciate ligament tears. Each knee was tested under a force 120 Newtons in a posterior to anterior direction to create anterior tibial translation at 20 degrees knee flexion. Side-to-side difference of anterior/posterior tibial translation (mm) was measured from radiographs. Measurement of rotation and translation by DYNEELAX was also recorded.
Adductor canal block is an effective analgesic technique for major knee surgery. However, the saphenous nerve block is not sufficient to explain this block's efficiency. It has been shown that adductor canal block can spread to the tibial and fibular nerves through the adductor hiatus. However this diffusion's frequency has never been measured. The main objective of this study is to assess the frequency of the spread of the adductor canal block to the fibular and tibial nerves assessed by ultrasound observation at the popliteal fossa.
By 2040, 25% of Canadians will have osteoarthritis, a disabling joint condition. Most people think osteoarthritis only affects older adults, but 50% of the 700,000 Canadian youth who hurt their knee playing sports annually will develop osteoarthritis by 40 years of age. These young people with old knees face knee pain and disability for much of their adult lives, interfering with parenting, work, and recreation. Yet, most do not know about osteoarthritis or how to reduce their risk. In this clinical trial, people who have torn the Anterior Cruciate ligament in their knee and had reconstruction surgery 9-36 months previously will be randomized to receive either a 6-month virtual education and exercise therapy program called Stop OsteoARthritis (SOAR) or a minimal intervention control program. Researchers will test if those who received the SOAR program have larger gains in knee health, including pain, symptoms, function, and quality of life at 6, 12, and 24 months. Researchers will also use MRIs (baseline and 24 months) to assess how the SOAR program influences knee cartilage degeneration and its cost-effectiveness.
This study will use electromyography to evaluate activation patterns of the vastus medialis and vastus lateralis muscles during the McMurray's knee examination test in different knee positions.
