Total Knee Arthroplasty (TKA)
Replacement may be considered when psoriatic arthritis leads to persistent knee pain, deformity, or imaging evidence of extensive joint surface destruction, and when medication and intra-articular treatments are insufficient to maintain function. The decision focuses on the extent of the lesion, alignment and stability, skin lesions and infection control, bone quality and activity needs, and overall health status, and is determined by a comprehensive assessment by a specialist team.

Stay Required
Typical hospitalization is approximately 4–7 days, affected by the surgical procedure (unilateral/bilateral, fixation method), anesthesia recovery, pain and thrombosis prevention, comorbidity management, and rehabilitation progress.
It is recommended to stay nearby for approximately 7–14 days after discharge for dressing changes, (if necessary) suture removal, rehabilitation assessment, and initial follow-up, to facilitate prompt treatment if problems arise.
In total (preoperative assessment + hospitalization + postoperative follow-up), it is generally recommended to stay for 2–4 weeks, depending on the actual schedule and recovery.

What is Total Knee Arthroplasty (TKA)?
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. Replacement may be considered when psoriatic arthritis leads to persistent knee pain, deformity, or imaging evidence of extensive joint surface destruction, and when medication and intra-articular treatments are insufficient to maintain function.

Preparation Before Treatment
Preoperatively, blood and coagulation tests, infection screening, electrocardiogram, and, if necessary, echocardiography/chest X-ray, and lower extremity thrombosis risk assessment are usually required. Assess the skin around the knee and psoriatic skin lesions, and perform skin management in advance if necessary. The doctor will develop a plan to discontinue and bridge previous medications (including anticoagulants, immune/biological agents). Prepare imaging data, previous medical records, and translated documents, and arrange travel and care. The above is subject to a medical consultation at the medical institution.

Administer general or spinal anesthesia.
None
Remove damaged cartilage and correct deformities.
Cold instruments
Insert and suture after confirming the gap with trial molds.
Suture
Monitor postoperative pain and risk of thrombosis.
None
Recovery Process
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.
None
Early ambulation and gait training as directed.
None
Follow-up and assessment of long-distance flight preparation.
None
Treatment Options
Optional plans and approaches include: continuous medication and physical therapy, arthroscopic debridement (for limited lesions), unicompartmental replacement, high tibial osteotomy, etc.; TKA can be cemented or uncemented, with different prosthesis designs and whether to use navigation/robot assistance. The choice depends on the extent of the lesion, alignment and stability, bone quality, and functional goals, and is determined after specialist assessment.

Frequently Asked Questions
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.
