Endothetic joint replacement
When articular surfaces are worn due to osteoarthritis or previous traumas, which cause severe pain, and conservative treatment is not sufficient, a surgery for endoprosthetic joint replacement is required. Endoprosthetic joint replacement is indicated for diseases, when the joint tissue is deteriorating; However, it can also be necessary for older people with femoral neck fractures or for not re-constructible fractures around the shoulder or caput radii. Endoprosthetic joint replacement surgery can be done on the joints of the shoulder, hip, knee, ankle, and great toe.
How Is the Surgery Performed?
The patient may undergo local, spinal, or general anaesthesia. Duration of the surgery can vary and strongly depends on which joint is being replaced. The surgical procedure embraces an open approach. The surgeon removes damaged articular surfaces together with part of the underlying bone using specialized tools, and replaces the cartilage and bone, which is removed, with the components of an endoprosthesis.
The shape of polymeric, ceramic and metal implants resembles the shape of natural articular surfaces. Depending on the fixation technique used to hold the implant in place, there are 2 types of implants:
* Cemented implants, which are held in place by bone cement;
* Cement-less implants, which are covered with hydroxyapatite crystals that help the new bone grow into the surface of the implant. This implant technology is very suitable for physically active people, because it ensures greater longevity for an artificial joint.
What Should be Known After Surgery?
- Once or twice a week the wound should be re-dressed;
- After 10-14 days, the sutures are removed;
- The patient can resume routine activities within three to four months;
- Depending on which joint was replaced during the surgery, the doctor may give you specific postoperative care guidelines.
