Osteoarthritis develops to the late stage, and the cartilage in the knee joint is worn out, and trying various methods cannot relieve the pain. Some patients consider artificial knee replacement, but many people are worried about whether artificial joint can replace native joints. Will you fall when walking on a prosthesis made of metal and plastic?
The possibility of falling does exist. Patients with advanced osteoarthritis generally have lower limb weakness , muscle atrophy, knee deformation , etc. The pain relieves and function recovers after artificial knee replacement, but the muscle strength is insufficient, The lack of balance force , and the human body lacks prosthesis and prosthesis. Prosthesis refers to the function of physical movement that can also be manipulated with eyes closed. These factors may cause patients to fall more than healthy people.
Falling within half a year after the operation
is still in the recovery stage at this time. As the prosthesis grows longer and becomes "solid", the body will adapt more and more. The risk is the greatest in the two months after the operation. If you accidentally fall or kneel down, you will fall or fall down accidentally. On the ground, physical injuries and loosening or dislocation of the prosthesis can be caused. Therefore, you must follow the doctor's advice in daily life. A study surveyed 134 patients with knee replacement, of which 23 fell within half a year after the operation, and has 67.7 % of people fall while walking, the most common cause is tripping and slipping, most falls occur at home (45.2%), as well as other indoor places (29%), and most of these patients are on the way to fall Walking aids such as crutches (87.1%) were not used as required.
In terms of injury, 4 patients suffered soft tissue damage after falling, but no fracture occurred. Although the damage caused by the fall may not be as large as expected, the number of people surveyed this time is limited. Just be careful just in case , once the prosthesis is dislocated, a secondary surgery may be required and the prosthesis may also be damaged.
Fall after complete recovery
The recovery time after artificial knee replacement varies from person to person. Generally, within half a year to one year, the patient almost completely restores his daily life function. Once he falls at this time, it is composed of cobalt chromium or the latest black gold The possibility of damage to the prosthesis is low, and they are actually stronger than human bones, and can cause damage unless they are loose or dislocated.
After falling, seek emergency medical treatment
After the operation, if you fall accidentally and these situations occur, be sure to seek medical treatment immediately:
- bleeding in the surgical area.
- suture breaks (opening).
- surgical area is painful and swelling.
- has difficulty walking.
- Knee joint motion range is reduced.
- Knee joint is unstable.
- any symptoms that have not occurred before.
What to do after falling
If the above situation occurs after falling, don't deal with it yourself. The family members will send the patient to the hospital as soon as possible. The risk is the greatest within two months after the operation. Please be careful. The doctor will first evaluate the degree of damage caused by the fall. Through X-ray and other imaging methods, we can determine whether the prosthesis is loose or dislocated, and the bleeding wound is treated, and rinsed and debride it.
Generally, if there is no bleeding, or if quadriceps is not damaged, you don’t have to be particularly nervous, and the possibility of damage to the prosthesis is small. In addition, not all falls will cause damage to the prosthesis. Or dislocation. If you sit or lie down for a long time and do not undergo rehabilitation exercises as required for fear of falling, the prosthesis will not be able to combine with the bones quickly, and may not grow firmly, muscle strength cannot be restored, and scars may be left. Organize, the result is not worth the loss.
