Hip Replacements May Drop 10% Thanks to Stem Cell Therapy

November 16, 2021

Surgeons have successfully used stem cells to slow the progression of osteonecrosis.
Researchers hope that the number of hip replacement operations will reduce by 10% using stem cell therapy.
The stem cells, harvested from the patient’s own body, can foster bone growth and improve blood flow to diseased tissue.

A new surgical technique may soon reduce the number of hip replacement surgeries by nearly 10%. Research has suggested that stem cells from a patient’s own body may provide regenerative properties that increase healing. Stem cells implanted at a surgical site can help bone regrow, increase blood flow, and reduce the risk of follow-up surgery. Danial Wiznia, MD, is an orthopedic surgeon with the Yale School of Medicine and has used stem cells to combat Osteonecrosis, a severe bone disease. Osteonecrosis occurs when bone cells, known as osteoblasts, cannot repair themselves and maintain the structure of the bone. As the bone weakens, blood flow to the affected area is decreased, increasing the speed of the bone’s weakening. Eventually, in most cases, the head of the femur collapses, and the only treatment is a total hip replacement. Physicians often diagnose osteonecrosis when a patient is in their 30s or 40s. The prospect of a total hip replacement presents a problem for patients who are relatively young when diagnosed. Hip transplants are known for long lifespans but receiving one at age 40 will almost certainly require that the patient undergo complicated surgery later in life to replace or repair the artificial hip joint. Dr. Wiznia uses stem cells from the patient’s own bone marrow to slow, and in some cases reverse, the progression of osteonecrosis. If caught early enough, stem cells can be introduced into the diseased area of the bone to reinforce and repair failing bone tissue. The treatment may not completely eliminate the long-term risk of a hip replacement, but it can offer short-term improvements and allow the patient more time before a replacement is required.
