• 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)
  • About one-third of this ligament is removed and subsequently secured to the femur and tibia to replace the torn ACL. (indiaprofile.com)
  • 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)
  • 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)
  • bone
  • 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)
  • 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)
  • 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)
  • 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)
  • Patellar Ligament
  • 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)
  • provide stability
  • Do you know how ligaments provide stability to your knees? (indigo.ca)
  • 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)
  • Intra-capsular ligaments, which are much less common,[citation needed] also provide stability but permit a far larger range of motion. (wikipedia.org)
  • Tear
  • 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)
  • 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)
  • Arthritis of the shoulder can be treated with total shoulder replacement, hemiarthroplasty (half a replacement), or a reverse shoulder implant (for arthritis with large rotator cuff tear). (wikipedia.org)
  • allograft
  • This includes Dacron graft/loop Bosworth screw Kirschner wires Hook plate Anatomic Repair, or any repair using tendon allograft without sacrificing the coracoacromial ligament. (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)
  • Arthritis is a condition that affects the cartilage of the joints. (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)
  • 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)
  • surfaces
  • A further classification is according to the number and shapes of the articular surfaces: flat, concave and convex surfaces. (wikipedia.org)
  • Types of articular surfaces include trochlear surfaces. (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)
  • procedure
  • the first stem cell articular cartilage repair procedure called Articular Cartilage Paste Grafting which in long-term studies have demonstrated an 80% success rate at improving pain and function for people with arthritis. (wikipedia.org)
  • The procedure is less effective in treating older patients, overweight patients, or a cartilage lesion larger than 2.5 cm. (wikipedia.org)
  • Certain tubular structures from the fetal period are referred to as ligaments after they close up and turn into cord-like structures:[citation needed] Broström procedure "ligament" at Dorland's Medical Dictionary Daniel John Cunningham (1918). (wikipedia.org)
  • Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. (wikipedia.org)
  • A separated shoulder can be treated with: Weaver-Dunn procedure Weaver-Dunn with various additional fixations (sutures, suture anchors, tendon autograft) to replace the coracoclavicular ligaments. (wikipedia.org)
  • Lateral
  • 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)
  • 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)
  • shoulder replacement
  • The next notable case in the evolution of shoulder replacement procedures was in 1955 when Charles Neer conducted the first hemiarthroplasty, essentially replacing only the humeral head, leaving the natural shoulder socket, or glenoid, in tact. (wikipedia.org)
  • In others, a conventional shoulder replacement may be indicated. (wikipedia.org)
  • The progression to shoulder replacement usually begins with the development of pain with movement of the shoulder and stiffness which will be conservatively managed with activity modification, physical therapy and nonsteroidal anti-inflammatory (NSAID) drugs. (wikipedia.org)
  • If all non-surgical, conservative treatment options fail and pain is affecting quality of life, then the shoulder replacement will likely be indicated. (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)
  • Various studies on shoulder replacements have confirmed this indication, noting specifically that severe glenohumeral arthritis as the cause. (wikipedia.org)
  • treatments
  • The objective of this study was to assess the effects of different decellularization treatments on articular cartilage constructs, engineered using a scaffoldless approach, after 4 wks of culture, using a two-phased approach. (pubmedcentralcanada.ca)
  • artificial
  • One of these techniques is the replacement of the ligament with an artificial material. (wikipedia.org)
  • Artificial ligaments are a synthetic material composed of a polymer, such as polyacrylonitrile fiber, polypropylene, PET (polyethylene terephthalate), or polyNaSS poly(sodium styrene sulfonate). (wikipedia.org)
