What Are the Risks of Knee Replacement Surgery? A Complete Guide
Knee replacement surgery has helped many people get back to a more comfortable, active life. Simple things like walking, climbing stairs, or even standing for longer become easier again.
That said, it’s still a major surgery. And like any procedure, it comes with a few risks that are worth understanding before you go ahead.
If you’re thinking about knee replacement, consulting an experienced Orthopedic Surgeon in Kandivali Dr Saurabh Talekar can help you clearly understand these risks and how they apply to your individual condition. Here’s a clear and honest look at what you should know and how the right care can make a big difference.
Who Is at Higher Risk for Complications?
Not everyone has the same recovery experience. Some factors can increase the chances of complications or slow down healing. You may fall into a higher-risk category if you:
- Are significantly overweight
- Have conditions like diabetes, heart issues, or blood disorders
- Smoke regularly
- Have had previous knee surgeries
- Are above 75 years of age
This doesn’t mean surgery isn’t an option—it just means your case needs a bit more planning and care.
Common Risks and Side Effects of Knee Replacement Surgery
While most knee replacement surgeries are successful, patients should be aware of the following risks:
|
Risk |
What You Should Know |
|
Blood Clots (DVT) |
Deep vein thrombosis can form in the leg after surgery. Blood thinners and early mobilization help reduce this risk significantly. |
|
Infection |
Wound or joint infections, though rare, can be serious. Surgeons use sterile technique and prophylactic antibiotics to minimize the chance. |
|
Implant Loosening |
Over time, the prosthetic joint may loosen, causing pain and instability. High-activity patients face a higher risk of implant wear. |
|
Stiffness & Limited Range |
Some patients experience stiffness post-surgery. Regular physiotherapy is essential to restore full knee flexibility and function. |
|
Nerve or Vessel Damage |
Rarely, surrounding nerves or vessels may be affected during surgery, leading to numbness or circulation issues. |
|
Anesthesia Complications |
Reactions to general or spinal anesthesia can occur. Pre-surgical health assessment minimizes anesthesia-related risks. |
