What are common Causes of Pain Behind the Knee After Surgery? While some discomfort is a normal part of recovery, persistent or localized pain behind the knee may indicate one of the following:
-
Soft Tissue Irritation
During surgery, tissues around the joint—including muscles, tendons, and ligaments—are stretched and manipulated. In particular, the hamstring tendons and gastrocnemius muscle, located behind the knee, can become inflamed or irritated during healing. This often leads to a dull ache or tightness in the back of the knee.
-
Swelling and Fluid Buildup
Post-surgical swelling is common and can lead to increased pressure behind the knee. In some cases, a Baker’s cyst (a fluid-filled sac behind the knee) may form or reappear after surgery, causing tightness and discomfort.
-
Nerve Sensitivity or Irritation
Surgical procedures can occasionally irritate nearby nerves. Numbness, tingling, or a burning sensation behind the knee may be the result of temporary nerve inflammation, which usually improves with time.
-
Scar Tissue (Arthrofibrosis)
Scar Tissue (Arthrofibrosis)Some patients develop excessive scar tissue, which may cause stiffness or pain when bending the knee. Known as arthrofibrosis, this condition can limit motion and put extra pressure on the back of the joint.
-
Incorrect Gait or Overcompensation
During recovery, it’s natural to walk differently to avoid pain—but altered posture or movement can lead to muscle fatigue or pain in areas like the back of the knee.
When Should You Be Concerned?
If you experience:
- Sharp or worsening pain
- Swelling that does not improve
- Redness or warmth around the knee
- Difficulty walking or bearing weight
- Fever or signs of infection
…you should contact your orthopedic provider immediately. These symptoms could indicate a complication that needs to be addressed promptly.
Managing Pain Behind the Knee
Most behind-the-knee discomfort can be managed with conservative care, such as:
- Ice and elevation
