“…The risk of OA development has earlier been suggested to relate to high-tibiofemoral loads in the medial compartment of the knee joint (Schipplein and Andriacchi 1991;Bruns et al 1993;Baliunas et al 2002). This is consistent with the present model which predicted specifically high-maximum principal stresses on the medial joint surface, as compared with the lateral compartment of the joint.…”

“…Even a small change in the varus -valgus rotation can alter greatly the load carrying capability between medial and lateral compartments (Bruns et al 1993). Due to the unrestricted varus -valgus rotation in this study, the total forces experienced by the medial and lateral sides of the knee joint were almost identical.…”

“…The varus -valgus angle has a significant role in distributing forces between the lateral and medial compartments of the knee joint (Bruns et al 1993;Moisio et al 2011), and it may be involved in the progression of lateral or medial osteoarthritis (OA) (Sharma et al 2010;Moisio et al 2011). Computational finite element (FE) models with a gait cycle load data may be used to evaluate the dynamic functional performance of joint tissues and even to pinpoint possible failure locations following joint injuries and disorders or surgical operations, such as meniscectomy.…”

Computational models can be used to evaluate the functional properties of knee joints and possible risk locations within joints. Current models with fibril-reinforced cartilage layers do not provide information about realistic human movement during walking. This study aimed to evaluate stresses and strains within a knee joint by implementing load data from a gait cycle in healthy and meniscectomised knee joint models with fibril-reinforced cartilages. A 3D finite element model of a knee joint with cartilages and menisci was created from magnetic resonance images. The gait cycle data from varying joint rotations, translations and axial forces were taken from experimental studies and implemented into the model. Cartilage layers were modelled as a fibril-reinforced poroviscoelastic material with the menisci considered as a transversely isotropic elastic material. In the normal knee joint model, relatively high maximum principal stresses were specifically predicted to occur in the medial condyle of the knee joint during the loading response. Bilateral meniscectomy increased stresses, strains and fluid pressures in cartilage on the lateral side, especially during the first 50% of the stance phase of the gait cycle. During the entire stance phase, the superficial collagen fibrils modulated stresses of cartilage, especially in the medial tibial cartilage. The present computational model with a gait cycle and fibril-reinforced biphasic cartilage revealed time- and location-dependent differences in stresses, strains and fluid pressures occurring in cartilage during walking. The lateral meniscus was observed to have a more significant role in distributing loads across the knee joint than the medial meniscus, suggesting that meniscectomy might initiate a post-traumatic process leading to osteoarthritis at the lateral compartment of the knee joint.

“…A joint contact area of approximately 30 mm 2 was calculated from the multibody model under maximal loading, applying a mean pressure of 6 N/mm 2 over the balancing side joint. Information on peak pressures within the jaw joint is limited, but this value can be viewed as high as it lies at the upper limit of that recorded in other joints (Armiger et al, 2009;Bei and Fregly, 2004;Bruns et al, 1993).…”

“…The word meniscus comes from the Greek word mēniskos, which means "crescent," diminutive of mēnē, meaning "moon" (Fox, Bedi, & Rodeo, 2012). The meniscus is an important weight-bearing structure that absorbs 50-70% of the load transmitted through the lateral and medial knee compartments (Bruns, Volkmer, & Luessenhop, 1993).…”

Background: Meniscal injuries are common among athletic populations and are one of the most common indications of knee joint surgeries. Meniscectomies are a common practice among orthopaedic surgeons in meniscal injury surgical treatment. Currently, no consensus exists for a standardized postoperative rehabilitation protocol after partial meniscectomy. Purpose: This article describes the development and validation of a new rehabilitation protocol for the management of meniscus injury after partial meniscectomy. Methods: A rehabilitation protocol for the postoperative meniscectomy was developed based on literature reviews. Evaluation from clinical experts were done by a 2-hour discussion with a group of seven clinicians to validate the protocol. Finally, an experimental design was used to test the effectiveness of the proposed protocol on a sample of 38 patients who had partial meniscectomies. Results: The final protocol included easy step-by-step directions for physiotherapists. The experts' validation process resulted in modifications related to clarity, feasibility, technical descriptions, and usability. Our experimental study showed significant improvement of knee joint functions compared to a conventional physiotherapy group. Conclusions: Our final protocol includes detailed instructions which a physiotherapist should be able to follow up rehabilitate patients who have undergone partial meniscectomy from the third day post-surgery until 8 weeks post-surgery. The protocol is clear, easy to follow, and applicable in rehabilitation settings.
