The most common situations that lead to the need for a revision hip replacement are instability / dislocation, mechanical loosening and infection. According to one national review study, instability issues account for 22% of all revision hip replacements, aseptic loosening for 20% and infection the cause of 15% of yearly revision hip replacement surgeries [3]. Periprosthetic fracture, component failure and osteolysis-related wear are the causes for the remaining revision hip replacements done each year. Of great concern looking forward is that infection by the year 2030 will account for 48% of all revision hip replacements that will be done [4]. This has grave economic implications as infection is one of the most expensive complicating events related to joint replacement surgery.

Each of these symptoms should be evaluated by the surgeon to help determine if the hip replacement has something wrong with it or if it is functioning as expected. A variety of tests are available to the surgeon and often many of them are necessary to sort out the issues that have left the primary hip replacement dysfunctional. Many of the common causes for failed total hip which would lead to the need for a revision of part or all of the prosthetic implant are discussed below.

Recent studies have confirmed that roughly 300,000 total hip replacements are done annually in the U.S with projected growth to reach 570,000 procedures each year within the next two decades [1]. It is expected that 50% of all total hips done will be on patients that are less than 65 years of age within the next few years [2]. Fortunately, with modern techniques, equipment and implants the hip replacements put in today have a 90% chance they will last 10-15 years.

Thousands of visiting surgeons to Wrightington were immediately convinced of the superiority of the Charnley joint and the metal on metal joint finally ended in the late 1970's when McKee and Ring themselves switched to metal on polyethylene articulations for their own hip replacement designs.

End of an era
Chamley died believing that his metal polyethylene joint had been totally vindicated.

The published results do not relate to young patients with an arthritic hip, they relate to young patients who have another built-in restraint giving them the activity level of an elderly inactive patient.

Charnley did use the McKee metal on metal joint in his clinical practice and he conceded that the McKee worked just as well in patients as his own commenting, "It is nice to know that both are British".

Peter Ring from Redhill, Surrey, provided the next development in hip arthroplasty (Fig.9).

He distrusted bone cement and developed a self locking total hip replacement for uncemented fixation.

10) This design also had a metal on metal articulation.

Thus, by the 1970's three types of total hip replacement were in common use: the McKee, Charnley and Ring types.

Surgeons across the world experienced initial success with all varieties and attention then focused on which would be more durable.

In sorting out persistent pain around the hip, infection is a distinct but uncommon diagnosis reported to occur in less than 1% of all total hips ever getting infected in most studies of this issue. Fortunately, there are many other causes for pain around the hip joint other than infection, but infection always remains a diagnosis that must be considered in dealing with painful hip replacements.
