If you’ve had a hip replacement and your hip still feels tight or stiff, you’re not alone. Many people feel frustrated when recovery doesn’t bring the full relief they expected. The good news? This tightness usually has a fixable cause.
Why Am I Still Feeling Tight?
Even if your new hip joint is healing well, you might still notice:
-
A pulling sensation in your groin
-
Trouble lifting your leg
-
Stiffness when walking or standing
-
That your hip just doesn’t “move right”
Often, this isn’t about the joint. It’s about the muscles around it. One of the most common culprits? The psoas muscle.
What’s the Psoas and Why Is It Important?
The psoas (pronounced so-az) is a deep core muscle that connects your spine to your thigh bone. It’s responsible for hip flexion. Like when you walk or climb stairs.
After surgery, the psoas can become tight or irritated from:
-
Inflammation around the surgical area
-
Scar tissue and guarding
-
Reduced movement during recovery
-
Muscle imbalance and compensation
When the psoas is tight, it can cause ongoing tension, pulling, and even pain. All while your new joint is technically “working fine.”
How Robotic Therapy Can Help
At our clinic, we use the RX-2600 therapeutic arm to release deep muscle tension like this. Including the psoas. In a safe, non-invasive way.
The robot allows us to:
-
Pinpoint tension in hard-to-reach muscles
-
Apply gentle, consistent pressure
-
Deliver therapeutic heat and vibration to help muscles relax
-
Re-train movement patterns without force
-
Combine robotics with manual therapy for faster recovery
Many of our clients feel looser and more mobile after just a few sessions.

Don’t Wait to Feel Better
If it’s been weeks or months since your hip replacement and you’re still struggling with tightness or discomfort, your psoas might be the reason.
We offer a free 15-minute robotic screening to see how the rx2600 can help you.
