Patella fracture; Other names: Broken kneecap: A fracture of the patella seen on a lateral view: Specialty: Orthopedics: Symptoms: Pain, swelling, bruising to front of the knee [1] Complications: Injury to the tibia, femur, or knee ligaments [2] Types: Stable, displaced, comminuted, open [1] Causes: Trauma to the front of the knee [1 ...
Periprosthetic in medicine refers to a structure in close relation to an implant. Clinically it can refer to: Bone fracture or 'periprosthetic fracture' [1] around an artificial joint, e.g. after a knee replacement; infection around an artificial joint or 'periprosthetic joint infection' [2] Vegetation or leak around an artificial heart valve
Periprosthetic fractures are becoming more frequent with the aging patient population and can occur intraoperatively or postoperatively. Depending on the location of the fracture and the stability of the prosthesis, these can be treated surgically with open reduction and internal fixation or revision of the prosthesis.

PJI is estimated to occur in approximately 2% of hip and knee replacements, and up to 4% of revision hip or knee replacements. Other estimates indicate that 1.4-2.5% of all joint replacements worldwide are complicated by PJIs. [1] The incidence is expected to rise significantly in the future as hip replacements and knee replacements become more ...
Nonunion is permanent failure of healing following a broken bone unless intervention (such as surgery) is performed. A fracture with nonunion generally forms a structural resemblance to a fibrous joint, and is therefore often called a "false joint" or pseudoarthrosis (from Greek pseudo-, meaning false, and arthrosis, meaning joint).
The Vancouver classification is a grading system used in orthopaedics to determine management of post-operative periprosthetic femoral fractures following a hip arthroplasty. It is named for the city Vancouver , home to the University of British Columbia where the authors of the 1995 paper worked.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
The knee anatomy provides insight into predicting why certain fracture patterns occur more often than others. The medial plateau is larger and significantly stronger than the lateral plateau. Also, there is a natural valgus or outward angulation alignment to the limb which coupled with the often valgus or outwardly angulating force on impact ...
