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)
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.
Osteoarthritis, Hip
Noninflammatory degenerative disease of the hip joint which usually appears in late middle or old age. It is characterized by growth or maturational disturbances in the femoral neck and head, as well as acetabular dysplasia. A dominant symptom is pain on weight-bearing or motion.
Knee
A region of the lower extremity immediately surrounding and including the KNEE JOINT.
Arthroplasty, Replacement, Knee
Replacement of the knee joint.
Knee Injuries
Knee Prosthesis
Replacement for a knee joint.
Cartilage, Articular
Menisci, Tibial
The interarticular fibrocartilages of the superior surface of the tibia.
Osteoarthritis, Spine
A degenerative joint disease involving the SPINE. It is characterized by progressive deterioration of the spinal articular cartilage (CARTILAGE, ARTICULAR), usually with hardening of the subchondral bone and outgrowth of bone spurs (OSTEOPHYTE).
Range of Motion, Articular
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.
Pain
Osteophyte
Tibia
Hand Joints
The articulations extending from the WRIST distally to the FINGERS. These include the WRIST JOINT; CARPAL JOINTS; METACARPOPHALANGEAL JOINT; and FINGER JOINT.
Anterior Cruciate Ligament
Patella
The flat, triangular bone situated at the anterior part of the KNEE.
Synovial Fluid
The clear, viscous fluid secreted by the SYNOVIAL MEMBRANE. It contains mucin, albumin, fat, and mineral salts and serves to lubricate joints.
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.
Synovial Membrane
The inner membrane of a joint capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes SYNOVIAL FLUID.

Treatment Outcome
Stifle
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.
Arthrography
Synovitis
Inflammation of a synovial membrane. It is usually painful, particularly on motion, and is characterized by a fluctuating swelling due to effusion within a synovial sac. (Dorland, 27th ed)
Viscosupplementation
A therapeutic treatment typically involving INTRA-ARTICULAR INJECTIONS of HYALURONIC ACID and related compounds. The procedure is commonly used in the treatment of OSTEOARTHRITIS with the therapeutic goal to restore the viscoelasticity of SYNOVIAL FLUID, decrease pain, improve mobility and restore the natural protective functions of hyaluronan in the joint.
Hyaluronic Acid
A natural high-viscosity mucopolysaccharide with alternating beta (1-3) glucuronide and beta (1-4) glucosaminidic bonds. It is found in the UMBILICAL CORD, in VITREOUS BODY and in SYNOVIAL FLUID. A high urinary level is found in PROGERIA.
Knee Dislocation
Slippage of the FEMUR off the TIBIA.
Arthroplasty, Replacement, Hip
Replacement of the hip joint.
Quadriceps Muscle
Medial Collateral Ligament, Knee
The ligament that travels from the medial epicondyle of the FEMUR to the medial margin and medial surface of the TIBIA. The medial meniscus is attached to its deep surface.
Viscosupplements
Viscoelastic solutions that are injected into JOINTS in order to alleviate symptoms of joint-related disorders such as OSTEOARTHRITIS.
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.
