What are the potential complications of knee arthroplasty?

The complications of knee arthroplasty generally include wound infection, knee joint adhesions, and common peroneal nerve injury, among others.

1. Wound infection: If the patient accidentally gets water on the wound or fails to pay attention to wound hygiene after knee arthroplasty, it may lead to wound infection, which may exacerbate pain at the surgical site.

2. Knee joint adhesions: If the patient remains immobilized for too long after surgery or refuses to undergo rehabilitation exercises due to knee pain, it can lead to knee joint adhesions in the later stages, severe cases may result in disuse atrophy of the limb. Therefore, patients need to follow the doctor's advice for rehabilitation exercises.

3. Common peroneal nerve injury: Encountering nerves during surgery may also lead to nerve damage, causing symptoms such as foot drop and varus deformity, which may require additional surgical treatment. The surgery may also cause complications such as epiphyseal plate injury, femoral fracture, and distal limb blood circulation disorders, which require prompt treatment. Meanwhile, attention should be paid to maintaining a light diet, ensuring balanced nutrition, and avoiding spicy and irritating foods.
