PJIs are the most common cause of knee replacement failures, and the third most common cause of hip replacement failures. [1] As of 2017, 2.1% of hip and 2.3% of knee replacements will at some time develop a PJI. [2] The incidence of PJIs have more than tripled in the last 20 years, with the incidence expected to further increase in the future.
Heterotopic ossification of varying severity can be caused by surgery or trauma to the hips and legs. About every third patient who has total hip arthroplasty (joint replacement) or a severe fracture of the long bones of the lower leg will develop heterotopic ossification, but is uncommonly symptomatic.
Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis.Other indications include rheumatoid arthritis, avascular necrosis, traumatic arthritis, protrusio acetabuli, [5] certain hip fractures, benign and malignant bone tumors, [6] arthritis associated with Paget's disease, [7] ankylosing spondylitis [8] and juvenile rheumatoid arthritis.

Osteolysis has been reported to occur as early as 12 months after implantation and is usually progressive. This may require a revision surgery (replacement of the prosthesis). [citation needed] Although osteolysis itself is clinically asymptomatic, it can lead to implant loosening or bone breakage, which in turn causes serious medical problems. [2]
It is experienced in a number of areas, making the diagnosis challenging, but commonly occurs in the groin, upper buttock/lower back, the buttock or beneath the buttock, side of the affected hip and posterior upper leg. [6] [3] [7] Onset of symptoms has been reported to present in both an acute and more gradual manner. [6]
Arthritis is a common acute or chronic condition affecting the joints and surrounding tissues. It’s estimated that roughly 18 percent of American adults have some form of arthritis. And about 44 ...
Posterior dislocations is when the femoral head lies posteriorly after dislocation. [5] It is the most common pattern of dislocation accounting for 90% of hip dislocations, [5] and those with an associated fracture are categorized by the Thompson and Epstein classification system, the Stewart and Milford classification system, and the Pipkin system (when associated with femoral head fractures).
