What are some negative claims about hip replacement surgery?

A:

Quick Answer

Negative claims about hip replacement surgery include heterotopic ossification, joint dislocation, leg length differential, blood clots and nerve injury. Other issues include infection, loosening of artificial joint parts and implant particle debris. Complications may occur during the surgery, during recovery or months to years after the surgery, according to WebMD.

The most common problem is loosening of the implant caused by tissue growth between the artificial parts and the bone, says WebMD. Symptoms are unlikely, but if significant pain occurs, a second hip replacement may be necessary.

Infection and hip dislocation are rare but may lead to additional surgery, according to WebMD. A doctor treats infections with antibiotics, but if the infection is deep in the joint, he may need to remove and replace the artificial components. Usually the doctor is able to move a dislocated hip back into place when the patient receives medication or anesthesia. Nerve injuries that cause numbness, tingling and muscle impairments are also rare but usually diminish or resolve completely.

Generally, heterotopic ossification and leg length differential do not cause functional limitations, states WebMD. The bone deposits in soft tissue surrounding the hip joint may decrease hip range of motion, but surgery is only necessary if the pain and decreased range of motion in the hip are significant. A difference in leg length is usually small, but a shoe insert can correct it when it's more noticeable.

The rubbing of the artificial ball-and-socket components against each other causes the release of implant particle, says WebMD. Some people develop sensitivities to the types of metal used.
