For the study, 30 athletes underwent gait analysis 6 months after ACL reconstruction. It was found that the knee adduction moment (generated by the combination of the ground reaction force that passes medial to the center of the knee joint, and the perpendicular distance of this force from the center of the joint) has a large influence on joint contact forces after surgery. my siteThis may provide a critical clue to understanding the mechanical pathway of post-traumatic osteoarthritis after ACL injury. Additional research is needed to identify other driving factors of joint loading in ACL-injured limbs and to help develop new therapies to prevent post-traumatic osteoarthritis. “Not only does this work demonstrate the important role of aberrant joint mechanics in post-traumatic osteoarthritis development, but it also indicates that its development is potentially preventable and not inevitable,” said Dr. Elizabeth Wellsandt, lead author of the Journal of Orthopaedic Research study, which was supported by the National Institute of Arthritis and Musculoskeletal and Skin Diseases and by the National Institutes of Health. ### Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.

Operative protocol usually encourages normal weight bearing through the new knee as this helps restore normal patterns of muscular activity and improves circulation. With a series of X-rays costing £400 and an MRI scan putting you back £1,500 the case for insurance cover becomes convincing. Petwise, Petplan, Pet Protect, PDSA, E&L, Animal Friends, and Marks and Spencer are all names in the market. To examine white blood cells and bacteria blood tests are performed. Knee replacement is becoming a more popular operation than hip replacement and as western populations get older the demand will increase. The first and usually the cheapest form, limits the claim to per condition per 12 months – suitable for one-off emergencies but not too good for diabetes! Veterinary care has moved quickly over the last ten years and as pets get older they are increasingly liable to suffer illness that can be expensive and lengthy to treat. According to research company lintel, one in three pets make an unplanned visit to the vet every year. When conservative measures are not helpful, such as physiotherapy, analgesics, walking aids and weight loss, then knee replacement is considered.
