The most common complications following Total Knee Arthroplasty (TKA), also known as knee replacement surgery, include blood clots, infection, nerve or tissue damage, and issues with the new knee joint itself.
Common TKA Complications Explained
Here's a breakdown of these complications:
- Blood Clots (Deep Vein Thrombosis - DVT):
- This is a significant risk after TKA because of changes in blood flow and clotting mechanisms following surgery.
- DVT can be dangerous if a clot travels to the lungs, causing a pulmonary embolism.
- Wound Infection:
- Infection at the surgical site is always a concern after any surgery.
- Infections can range from superficial to deep and may require antibiotics or further surgery to resolve.
- Damage to Nerves or Tissue:
- During surgery, nerves and tissues around the knee can be damaged.
- This can lead to pain, numbness, or weakness.
- Problems with Your New Knee:
- This is a broad category that includes issues such as:
- Stiffness: Difficulty bending or straightening the knee.
- Instability: A feeling that the knee is giving way.
- Loosening: The components of the knee replacement can become loose over time.
- Pain: Persistent pain despite the surgery.
- This is a broad category that includes issues such as:
| Complication | Description |
|---|---|
| Blood Clots (DVT) | Formation of blood clots in the deep veins, often in the legs, due to altered blood flow post-surgery. |
| Wound Infection | Infection at the site of the surgery, which can be superficial or deep and may require antibiotic treatment or further surgical intervention. |
| Nerve/Tissue Damage | Damage to surrounding nerves or tissues during the surgical procedure, potentially resulting in pain, numbness, or weakness. |
| Problems with New Knee | A range of issues including stiffness, instability, loosening of the implant, or persistent pain after the surgery. |
