What
Total knee arthroplasty is performed under general or spinal anesthesia. Cemented or uncemented fixation and prosthesis type are optional, determined based on assessment. Typically, damaged cartilage and a small amount of bone are removed, deformities are corrected, trial molds are used to confirm the gap, and then the implant is inserted and sutured. Postoperative monitoring includes pain, bleeding, and thrombosis. Activity is initiated as early as possible under rehabilitation guidance to improve function. The above is general health information and not medical advice; specific details are subject to specialist assessment and hospital protocols.
How
- Administer general or spinal anesthesia.
- Remove damaged cartilage and correct deformities.
- Insert and suture after confirming the gap with trial molds.
- Monitor postoperative pain and risk of thrombosis.
Recovery
Postoperatively, focus on monitoring pain, bleeding, and the risk of thrombosis. Follow medical advice for early ambulation and gait training, gradually transitioning to crutches/walkers. Keep the incision clean and dry, and seek prompt medical attention if there is oozing, redness, swelling, or fever. Follow-up and rehabilitation are often performed in stages; long-distance flights require assessment and the implementation of thrombosis prevention measures. Metal implants may trigger security checks, so it is recommended to carry proof of implantation.
- Monitor incision pain and risk of thrombosis.
- Early ambulation and gait training as directed.
- Follow-up and assessment of long-distance flight preparation.
FAQ
When can I fly back?
Arrangements need to be made in conjunction with recovery and thrombosis risk assessment, only when the doctor deems it safe, and following preventive measures.
Is a blood transfusion necessary?
Whether a blood transfusion is needed depends on intraoperative bleeding and postoperative hemoglobin levels; the hospital will assess and manage it according to specifications.
How long will the prosthesis last?
Related to age, weight, activity level, bone quality, and alignment. Regular follow-up is required to monitor wear and loosening; no uniform time limit is promised.
How soon can I walk after surgery?
Most patients attempt weight-bearing and walking early under protection; the specific pace is determined by rehabilitation and surgical assessment.
How long does the surgery usually last?
Usually several hours, depending on anatomical conditions, surgical complexity, and whether it is bilateral; subject to actual intraoperative conditions.
What rehabilitation exercises are needed?
Usually includes joint range of motion and quadriceps strength training, gait and stair training; the content and intensity are determined by the rehabilitation therapist's assessment.
Will metal implants affect airport security checks?
May trigger metal detection, it is recommended to carry proof of implantation or a medical record summary for security personnel to check.
Do I need to stop biological agents or anticoagulants?
May need to be adjusted, and an individualized plan will be jointly developed by the rheumatology, anesthesiology, and surgical teams; please refer to the doctor's advice during the consultation.
