What is prosthetic infection?
Prosthetic joint infection (PJI), also referred to as periprosthetic infection, is defined as infection involving the joint prosthesis and adjacent tissue.
What causes periprosthetic infection?
Causes and Diagnoses of Prosthetic Joint Infections Most prosthetic joint infections are the result of bacteria—often Staphylococcus aureus—present in the body or introduced during the surgery itself or subsequent procedures.
What is infected joint?
Septic arthritis is an infection in the joint (synovial) fluid and joint tissues. It occurs more often in children than in adults. The infection usually reaches the joints through the bloodstream. In some cases, joints may become infected due to an injection, surgery, or injury.
How common are prosthetic joint infection?
The current rate of prosthetic joint infection varies from one center to another but typically range between 0.5% to 1.0% for hip and shoulder replacements, and 0.5% to 2% for knee replacements [10][11]. Infection rates are higher in the first 2 years compared to after two years following surgery.
What is a prosthetic joint?
A prosthesis is a device designed to replace a missing part of the body, or to make a part of the body work better. The metal prosthetic device in knee joint replacement surgery replaces cartilage and bone which is damaged from disease or aging.
What is the meaning of periprosthetic fractures?
A periprosthetic hip fracture is a broken bone that occurs around the implants of a total hip replacement. It is a serious complication that most often requires surgery.
What causes joint infection?
These infections begin when disease-carrying bacteria enter the body, often after a trauma or a surgical procedure, and spread to the bones and joints through the bloodstream. Without prompt treatment, bone and joint infections can become long-term conditions.
What causes bone and joint infection?
Bone and joint infections are usually caused by bacteria called Staphylococcus aureus (or “staph”) and require treatment with antibiotics. A serious form of staph known as methicillin-resistant Staphylococcus aureus (MRSA) causes infections that can be more severe and need special antibiotics to treat.
How are prosthetic joints made?
The stem portion is generally made of a strong, corrosion resistant metal such as titanium, or cobalt and chromium alloys. The rest of the joint may be fashioned from a combination of high-density plastics, metal alloys, or ceramics. Knee joints are likewise often made from titanium and ceramics.
How long do you treat a prosthetic joint infection?
Antibiotic therapy duration for prosthetic joint infections treated by debridement and implant retention (DAIR): similar long-term remission for 6 weeks as compared to 12 weeks.
What is periprosthetic fracture knee?
Knee periprosthetic fractures are defined as fractures of the femur or tibia occurring within 15 cm from the joint line or 5 cm from the endomedullary stem if present (1, 2). Patella fractures in presence of a TKA are also considered as periprosthetic fractures (1, 2).
What are the symptoms of joint infection?
Bacterial joint inflammation is a serious and painful infection in a joint. It’s also known as bacterial or septic arthritis….They may include:
- elevated body temperature.
- pain in a joint.
- swelling and redness.
- warm skin over the joint.
- lack of appetite.
- fatigue.
- elevated heart rate.
What is prosthetic arthritis?
Prostheses replace joints that are very damaged by osteoarthritis by joints in synthetic materials. The indication is never urgent because it is, before all else, for improving comfort.
Which infection causes joint pain?
Septic arthritis is also known as infectious arthritis, and is usually caused by bacteria. It can also be caused by a virus or fungus. The condition is an inflammation of a joint that’s caused by infection. Typically, septic arthritis affects one large joint in the body, such as the knee or hip.
What are types of bone infections?
Bone infections are called osteomyelitis (from osteo [bone], plus myelitis [inflammation of the marrow]). Hematogenous osteomyelitis and contiguous-focus osteomyelitis are the two major types of bone infections. Both types can progress to a chronic bone infection characterized by large areas of dead bone.
What means artificial joint?
By definition, an artificial joint is a prosthesis or prosthetic joint, made of plastic, ceramic or metal, which is implanted to replace a damaged or diseased natural joint. Joints can become damaged by arthritis and other diseases, injuries, or from other causes such as obesity.
How is a periprosthetic fracture treated?
Essentially all periprosthetic fractures require some treatment. Stable nondisplaced fractures may only require protected weightbearing or cast/brace immobilization (and pain medication), but most unstable peri-implant fractures require surgical stabilization, implant replacement, or both to restore function.
What is the incidence of periprosthetic joint infection (PJI)?
Periprosthetic joint infection (PJI) is one of the most challenging complications after total joint arthroplasty, with an incidence of 1% to 4% after primary TKA [8, 9, 27, 28] and 1% to 2% after primary THA [24, 31]. This complication poses challenges on many fronts, one of which is the difficulty in reaching a diagnosis [24, 26, 37].
What is periprosthetic fracture?
Bone fracture or ‘periprosthetic fracture’ around an artificial joint, e.g. after a knee replacement infection around an artificial joint or ‘periprosthetic joint infection’
What is a periprosthetic?
Jump to navigation Jump to search. Periprosthetic in medicine refers to a structure in close relation to an implant. Clinically it can refer to: Bone fracture or infection around an artificial joint, e.g. after a knee replacement.
Is there a gold standard for diagnosing periprosthetic joint infection?
The diagnosis of periprosthetic joint infection (PJI) continues to pose a challenge. While many diagnostic criteria have been proposed, a gold standard for diagnosis is lacking. Use of multiple diagnostic criteria within the joint arthroplasty community raises concerns in patient treatment and comparison of research pertaining to PJI.
