Around 15 percent of hip replacements last less than 20 years, as stated by WebMD. On rare occasions, patients may experience complications, such as joint dislocation, broken replacement parts and nerve injuries, following a hip replacement surgery.
Although hip replacement surgery is one of the most successful types of orthopaedic operations performed, the joint generally begins wearing away after 15 to 20 years, requiring a revision surgery to replace the artificial hip, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. This procedure is more complicated than the initial surgery.
Hip dislocation is the most common complication to arise immediately after a hip replacement surgery, and the ball is most likely to become dislodged from the socket if the knees are drawn to the chest, notes the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The implant may also become loosened if the surrounding tissue becomes inflamed as the implant releases small particles, but this complication generally arises later.
Around 3 to 5 percent of patients require re-operation within the first 10 years, according to the Dorr Arthritis and Education Foundation. Certain lifestyle factors, such as smoking, drug abuse, alcohol use and nutritional deficiencies, may affect the outcome of a hip replacement surgery, increasing the risk of certain complications.
