Knee Prosthesis
Replacement for a knee joint.
Arthroplasty, Replacement, Knee
Replacement of the knee joint.
Prosthesis Failure
Osteoarthritis, Knee
Noninflammatory degenerative disease of the knee joint consisting of three large categories: conditions that block normal synchronous movement, conditions that produce abnormal pathways of motion, and conditions that cause stress concentration resulting in changes to articular cartilage. (Crenshaw, Campbell's Operative Orthopaedics, 8th ed, p2019)
Joint Prosthesis
Knee
A region of the lower extremity immediately surrounding and including the KNEE JOINT.
Prosthesis-Related Infections
Hip Prosthesis
Replacement for a hip joint.
Prostheses and Implants
Artificial substitutes for body parts, and materials inserted into tissue for functional, cosmetic, or therapeutic purposes. Prostheses can be functional, as in the case of artificial arms and legs, or cosmetic, as in the case of an artificial eye. Implants, all surgically inserted or grafted into the body, tend to be used therapeutically. IMPLANTS, EXPERIMENTAL is available for those used experimentally.
Range of Motion, Articular
Tibia
The second longest bone of the skeleton. It is located on the medial side of the lower leg, articulating with the FIBULA laterally, the TALUS distally, and the FEMUR proximally.
Knee Injuries
Penile Prosthesis
Cementation
The joining of objects by means of a cement (e.g., in fracture fixation, such as in hip arthroplasty for joining of the acetabular component to the femoral component). In dentistry, it is used for the process of attaching parts of a tooth or restorative material to a natural tooth or for the attaching of orthodontic bands to teeth by means of an adhesive.
Reoperation
Heart Valve Prosthesis
A device that substitutes for a heart valve. It may be composed of biological material (BIOPROSTHESIS) and/or synthetic material.
Patella
The flat, triangular bone situated at the anterior part of the KNEE.
Polyethylenes
Synthetic thermoplastics that are tough, flexible, inert, and resistant to chemicals and electrical current. They are often used as biocompatible materials for prostheses and implants.
Joint Instability
Lack of stability of a joint or joint prosthesis. Factors involved are intra-articular disease and integrity of extra-articular structures such as joint capsule, ligaments, and muscles.
Visual Prosthesis
Polyethylene
A vinyl polymer made from ethylene. It can be branched or linear. Branched or low-density polyethylene is tough and pliable but not to the same degree as linear polyethylene. Linear or high-density polyethylene has a greater hardness and tensile strength. Polyethylene is used in a variety of products, including implants and prostheses.
Posterior Cruciate Ligament
Equipment Failure Analysis
Biomechanical Phenomena
Bone Cements
Adhesives used to fix prosthetic devices to bones and to cement bone to bone in difficult fractures. Synthetic resins are commonly used as cements. A mixture of monocalcium phosphate, monohydrate, alpha-tricalcium phosphate, and calcium carbonate with a sodium phosphate solution is also a useful bone paste.
Prosthesis Fitting
Postoperative Complications
Neural Prostheses
Treatment Outcome
Osteoarthritis
A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.
Debridement
Ossicular Prosthesis
Femur
The longest and largest bone of the skeleton, it is situated between the hip and the knee.
Dental Prosthesis
An artificial replacement for one or more natural teeth or part of a tooth, or associated structures, ranging from a portion of a tooth to a complete denture. The dental prosthesis is used for cosmetic or functional reasons, or both. DENTURES and specific types of dentures are also available. (From Boucher's Clinical Dental Terminology, 4th ed, p244 & Jablonski, Dictionary of Dentistry, 1992, p643)
Follow-Up Studies
Dental Prosthesis, Implant-Supported
Recovery of Function
Heart Valve Prosthesis Implantation
Amputees
Retrospective Studies
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
Blood Vessel Prosthesis
Arthritis, Rheumatoid
A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.
Maxillofacial Prosthesis
Larynx, Artificial
A device, activated electronically or by expired pulmonary air, which simulates laryngeal activity and enables a laryngectomized person to speak. Examples of the pneumatic mechanical device are the Tokyo and Van Hunen artificial larynges. Electronic devices include the Western Electric electrolarynx, Tait oral vibrator, Cooper-Rand electrolarynx and the Ticchioni pipe.
Eye, Artificial
A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)
Penile Implantation
Arthroplasty, Replacement, Hip
Replacement of the hip joint.
Prospective Studies
Dental Prosthesis Design
The plan and delineation of dental prostheses in general or a specific dental prosthesis. It does not include DENTURE DESIGN. The framework usually consists of metal.
Bioprosthesis
Prosthesis, usually heart valve, composed of biological material and whose durability depends upon the stability of the material after pretreatment, rather than regeneration by host cell ingrowth. Durability is achieved 1, mechanically by the interposition of a cloth, usually polytetrafluoroethylene, between the host and the graft, and 2, chemically by stabilization of the tissue by intermolecular linking, usually with glutaraldehyde, after removal of antigenic components, or the use of reconstituted and restructured biopolymers.
Weight-Bearing
The physical state of supporting an applied load. This often refers to the weight-bearing bones or joints that support the body's weight, especially those in the spine, hip, knee, and foot.
Anterior Cruciate Ligament
Silicone Elastomers
Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.
Polyethylene Terephthalates
Dental Prosthesis Retention
Holding a DENTAL PROSTHESIS in place by its design, or by the use of additional devices or adhesives.
Aortic Valve
Amputation Stumps
The part of a limb or tail following amputation that is proximal to the amputated section.
Bone Malalignment
Menisci, Tibial
The interarticular fibrocartilages of the superior surface of the tibia.
Medial Collateral Ligament, Knee
Arthroplasty
Surgical reconstruction of a joint to relieve pain or restore motion.
Denture, Partial, Fixed
A partial denture attached to prepared natural teeth, roots, or implants by cementation.
Cartilage, Articular
Reconstructive Surgical Procedures
Maxillofacial Prosthesis Implantation
Surgical insertion of an appliance for the replacement of areas of the maxilla, mandible, and face. When only portions of the mandible are replaced, it is referred to as MANDIBULAR PROSTHESIS IMPLANTATION.
Chromium Alloys
Pain Measurement
Scales, questionnaires, tests, and other methods used to assess pain severity and duration in patients or experimental animals to aid in diagnosis, therapy, and physiological studies.
Joint Diseases
'Joint diseases' is a broad term that refers to medical conditions causing inflammation, degeneration, or functional impairment in any part of a joint, including the cartilage, bone, ligament, tendon, or bursa, thereby affecting movement and potentially causing pain, stiffness, deformity, or reduced range of motion.
Femoral Neoplasms
Femoral neoplasms refer to abnormal growths or tumors, benign or malignant, located in the femur bone or its surrounding soft tissues within the thigh region.
Osseointegration
Hip Joint
The joint that is formed by the articulation of the head of FEMUR and the ACETABULUM of the PELVIS.
