  • bone
  • Shoulder replacement is also recommended in cases of osteonecrosis (bone death), a condition where the blood vessels do not heal after an injury and the blood supply to that area stops. (healthpages.org)
  • If you show up with an arthritic knee that is bone-on-bone in all or part of the joint, the surgeon may suggest a total joint replacement to replace all of the exposed surfaces with metal and plastic. (sfexaminer.com)
  • The surgeon without this experience may offer an osteotomy, a surgical procedure where the angle of the leg is changed by cutting the bone and wedging it open or closed in order to buy time before a knee replacement is required. (sfexaminer.com)
  • At birth, the kneecap is just formed from cartilage, and this will ossify (change to bone) between the ages of three and five years. (wikipedia.org)
  • Cartilage is a thin, elastic tissue that protects the bone and makes certain that the joint surfaces can slide easily over each other. (wikipedia.org)
  • In the TTO procedure, the tibia has three osteotomies (cuts into the bone with a bone saw) performed upon it with the aim of realigning the tibial plateau slope so that it ultimately becomes aligned at right angles to the patellar ligament instead of sloping backwards. (wikipedia.org)
  • Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny fractures in the underlying bone. (wikipedia.org)
  • However, acute traumatic osteochondral lesions or surgically created lesions extending into subchondral bone, e.g. by Pridie drilling, spongialization abrasion or microfracture causing the release of multipotent mesenchymal stem cells from the bone marrow, may heal with repair tissue consisting of fibrous tissue, fibrocartilage or hyaline-like cartilage. (wikipedia.org)
  • The quality of the repair tissue after these "bone marrow stimulating techniques" depends on various factors including the species and age of the individual, the size and localization of the articular cartilage defect, the surgical technique, e.g., how the subchondral bone plate is treated, and the postoperative rehabilitation protocol. (wikipedia.org)
  • Blood and bone marrow (which contains stem cells) seep out of the fractures, creating a blood clot that releases cartilage-building cells. (wikipedia.org)
  • The effectiveness of cartilage growth after microfracture surgery is thought to be dependent on the patient's bone marrow stem cell population and some think increasing the number of stem cells increases the chances of success. (wikipedia.org)
  • A couple of physicians are promoting an alternative treatment implanting autologous mesenchymal stem cells directly into the cartilage defect, without having to penetrate the subchondral bone. (wikipedia.org)
  • Periodontal ligament: a group of fibers that attach the cementum of teeth to the surrounding alveolar bone. (wikipedia.org)
  • The differences in them are in the connections that they make: ligaments connect one bone to another bone, tendons connect muscle to bone, and fasciae connect muscles to other muscles. (wikipedia.org)
  • Ligaments connect bones to other bones to form joints, while tendons connect bone to muscle. (wikipedia.org)
  • Osteoarthritis (OA) is a type of joint disease that results from breakdown of joint cartilage and underlying bone. (wikipedia.org)
  • It develops as cartilage is lost and the underlying bone becomes affected. (wikipedia.org)
  • The labrum is a ring of cartilage on the rim of a shallow socket in the scapula into which the head of the upper arm bone normally fits and rotates. (wikipedia.org)
  • Cartilage prevents the bone ends from rubbing directly onto each other. (wikipedia.org)
  • collateral ligaments
  • The resulting series of transverse axes permit the sliding and rolling motion in the flexing knee while ensuring the collateral ligaments are sufficiently lax to permit the rotation associated with the curvature of the medial condyle about a vertical axis. (wikipedia.org)
  • femur
  • The main articular bodies of the femur are its lateral and medial condyles. (wikipedia.org)
  • Anteriorly, the synovial membrane is attached on the margin of the cartilage both on the femur and the tibia, but on the femur, the suprapatellar bursa or recess extends the joint space proximally. (wikipedia.org)
  • Its surface is smooth, coated with cartilage in the fresh state, except over an ovoid depression, the fovea capitis, which is situated a little below and behind the center of the head, and gives attachment to the ligament of head of femur. (wikipedia.org)
  • Cerezal)" If there is a fracture of the neck of the femur, the blood supply through the ligament becomes crucial. (wikipedia.org)
  • Radiograph of a healthy human hip joint Gross pathology specimen of the head of the femur with some synovium attached at the bottom and the ligament attached at the top. (wikipedia.org)
  • osteoarthritis
  • Deficiency of the ACL changes the kinematics at the knee joint and results in abnormal loading and increased translation of the tibio-femoral joint, which in turn results in articular cartilage damage and development of osteoarthritis [ 1 - 3 ], particularly in the lateral compartment [ 4 ]. (pubmedcentralcanada.ca)
  • Patients between the ages of 50 and 85 years who were admitted to our unit for elective total knee replacement for primary or secondary osteoarthritis and were able to give consent were eligible for inclusion. (pubmedcentralcanada.ca)
  • Shoulder replacement is used when there is severe destruction of the humeral head and glenoid surface from osteoarthritis, rheumatoid arthritis, osteonecrosis, or trauma. (healthpages.org)
  • The most common cause for shoulder joint replacement is osteoarthritis or degeneration of the joint. (healthpages.org)
  • In osteoarthritis this cartilage becomes worn and rough causing inflammation and pain and may lead to the need for surgical knee replacement. (sciencephoto.com)
  • Instability of a joint can over time lead to wear of the cartilage and eventually to osteoarthritis. (wikipedia.org)
  • Carpometacarpal osteoarthritis (CMC OA) of the thumb occurs when the cushioning cartilage of the joint surfaces wears away, resulting in damage of the joint. (wikipedia.org)
  • The most common form of arthritis, osteoarthritis (also known as degenerative joint disease), occurs following trauma to the joint, following an infection of the joint or simply as a result of aging and the deterioration of articular cartilage. (wikipedia.org)
  • torn
  • An artificial ligament is a reinforcing material that is used to replace a torn ligament, such as the ACL. (wikipedia.org)
  • In sports and orthopedics, people will sometimes speak of "torn cartilage" and actually be referring to an injury to one of the menisci. (wikipedia.org)
  • Lateral
  • The joint is not stable, however, when it is physically manipulated by attempting to move the tibia cranially.This contrasts with previous methods of CrCL repair which aimed to provide stability to the joint by replacing the ligament either with a fascial graft within the joint, or using a prosthesis made of nylon placed externally from the lateral fabella to a hole drilled in the tibial crest. (wikipedia.org)
  • wears away
  • Further on, chances are high that after only 1 or 2 years of the surgery symptoms start to return as the fibrocartilage wears away, forcing the patient to reengage in articular cartilage repair. (wikipedia.org)
  • As the cartilage lining wears away, the protective lining between the bones is lost. (wikipedia.org)
  • Arthritis
  • An example of a translational research study would be to determine if a drug's ability to increase cartilage cell metabolism could be translated into a clinical treatment of arthritis. (vin.com)
  • The situation is a little like a chicken-and-egg scenario: it is usually accepted that the CrCL ruptures because arthritis has caused the ligament to weaken because of poor joint fluid characteristics, but what causes the arthritis in the first place - a partial cruciate tear? (wikipedia.org)
  • Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage. (wikipedia.org)
  • Arthritis is a condition that affects the cartilage of the joints. (wikipedia.org)
  • Various studies on shoulder replacements have confirmed this indication, noting specifically that severe glenohumeral arthritis as the cause. (wikipedia.org)
  • Most challenging was the initiation of Joints Replacement with Artificial Implants of the Hip and Knee for diseases such as Arthritis (Rheumatism). (wikipedia.org)
  • joints
  • This is one reason why dislocated joints must be set as quickly as possible: if the ligaments lengthen too much, then the joint will be weakened, becoming prone to future dislocations. (wikipedia.org)
  • citation needed] Athletes, gymnasts, dancers, and martial artists perform stretching exercises to lengthen their ligaments, making their joints more supple. (wikipedia.org)
  • Tear
  • The ACL is one of the ligaments crucial to knee stability and persons who tear their ACL often seek to undergo reconstructive surgery, which can be done through a variety of techniques and materials. (wikipedia.org)
  • patellar
  • This shear force develops because the canine tibial plateau - the weight-bearing aspect of the joint - is sloped caudally (downwards towards the back of the joint)and there is an acute angle between the tibial plateau slope and the patellar ligament. (wikipedia.org)
  • The TTA neutralises shear force within the stifle by advancing the tibial tuberosity until the tibial plateau is at right angles to the patellar ligament. (wikipedia.org)
