Post-Operative Care and Concerns After Knee Tumor Surgery (PVNS)

Postoperative care after knee tumor resection?

Last week, I underwent surgery for the removal of a knee tumor (PVNS), and I have wounds on both sides of my knee.
I would like to ask: 1.
Is it normal to have noticeable swelling in my thigh and persistent pain in the front of my thigh (both when pressed and during movement)? Are there any ways to improve this? 2.
It has been a week since the surgery, and I still occasionally have a low fever (the suture wound shows no signs of infection, but there are blisters around the wound due to swelling in the knee).
Why is this happening?

Post-operative care after knee tumor surgery, particularly for conditions like pigmented villonodular synovitis (PVNS), is crucial for recovery and minimizing complications. Here are detailed insights regarding your concerns:
1. Swelling and Pain in the Thigh: It is quite common to experience swelling and pain in the thigh after knee surgery. This can be attributed to several factors, including the surgical trauma, inflammation, and the body's natural healing response. The swelling is often due to fluid accumulation (edema) in the tissues surrounding the surgical site. Pain, especially in the front of the thigh, can occur due to muscle strain or irritation of the surrounding tissues during the surgical procedure.

To manage this swelling and pain, consider the following strategies:
- Elevation: Keep your leg elevated above the level of your heart when resting. This can help reduce swelling by promoting venous return and decreasing fluid accumulation.

- Ice Therapy: Applying ice packs to the swollen area can help reduce inflammation and numb the pain. Use ice for 15-20 minutes every few hours, ensuring that you have a cloth barrier to protect your skin.

- Compression: Using a compression bandage can help control swelling. However, ensure it is not too tight, as this could impede circulation.

- Gentle Movement: While rest is important, gentle movements and exercises as advised by your physical therapist can help improve circulation and reduce stiffness. Avoid any activities that cause significant pain.

- Pain Management: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain and reduce inflammation. Always consult your physician before taking any medication.

2. Occasional Low-Grade Fever: Experiencing a low-grade fever after surgery can be concerning, but it is not uncommon. Post-operative fever can result from several factors, including:
- Inflammatory Response: The body often reacts to surgical trauma with an inflammatory response, which can lead to a mild fever.

- Fluid Accumulation: The presence of fluid (like the blisters you mentioned) around the surgical site can also contribute to a low-grade fever. This fluid may be a result of inflammation or a seroma, which is a collection of fluid that can occur post-surgery.

- Infection: While you mentioned that there is no visible infection at the incision site, it is still essential to monitor for any signs of infection, such as increased redness, warmth, or discharge from the wound.

If the fever persists or worsens, or if you notice any signs of infection, it is crucial to contact your healthcare provider. They may want to evaluate the surgical site and possibly perform additional tests to rule out any complications.

In summary, while some swelling, pain, and low-grade fever can be expected after knee tumor surgery, it is essential to monitor these symptoms closely. Adhering to post-operative care guidelines, including elevation, ice application, and gentle movement, can significantly aid in recovery. Always maintain open communication with your healthcare provider regarding any concerns or changes in your condition to ensure a smooth recovery process.
