The study opens the way to search for solutions to avoid the surgery complications.

In a study conducted by Hospital 57357’s orthopedic department, to investigate the ratio of complications after removal of osteosarcoma tumor or Ewing’s sarcoma and fixing an artificial knee joint, it was found that one third of patients get complications in the joint, and need another surgery.

According to Dr. Ahmed Alghonaimy, head of Hospital 57357’s orthopedic department, osteosarcoma develops mainly within growing bone tissues, while Ewing’s sarcoma develops in immature tissues of bone marrow, and the two types are common in childhood and teenage stages.

Most of the time the tumor develops near the knee joint, which requires replacing the knee joint with an artificial one.

In our study we investigated the percentage of complications and the need for a second surgery after fixing this type of joint for this young age bracket. It was found that within 8 years after the surgery one third of patients need another surgery to treat the joint complications, where after this surgery the patients retrieve the ability to practice most of the activities with efficiency between good and excellent.

According to the study, we noticed the spread of two types of complications after the surgery, pushing failure and stress shielding in the bones surrounding the joint. The study makes it possible to find solutions for these complications through performing modifications in the artificial joint design, by changing the material used or changing the joint engineering design.
