It paves the way for new techniques to avoid drawbacks after the surgery
A research paper posted in the Clinical Orthopedic and Research journal carried out by 57357’s orthopedic department examines the ratio of patients with drawbacks that follow the resection of osteosarcoma or Ewing’s sarcoma tumor and putting a modeled knee joint and the need for a surgical revision.
“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”, mentions, Dr. Ahmed Alghonaimy, head of Hospital 57357’s orthopedic department.
Usually the tumor progress is close to the knee joint, which needs a substitution of the affected knee joint with an artificial one.
In this research, the researchers studied the percentage of patients that develop complications and the need for a second surgery after putting this type of joint for patients at a young age. It was observed that within 8 years after the surgery, about one-third of the patients need another surgery to fix the joint complications, where after this surgery patients became able to regain the ability to practice the majority of their life activities with an efficiency ranging from good to excellent.
According to this 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 research paper opens the way to seek solutions for these complications by applying some adjustments in the modeled joint design, either by altering the material used or changing the joint manufacturing design.
