4 Signs You May Need ACL Reconstruction

A sudden “pop” in your knee, followed by pain and instability, can stop you in your tracks. How do you know if your injury will heal with rest and therapy, or if ACL reconstruction is the right next step?

Patients with knee injuries have trusted the Union County Orthopaedic Group team since 1966 for comprehensive, compassionate care. Our specialists are here to assess your symptoms and help you make a more informed decision to avoid long-term knee problems.

In this blog, you’ll learn four common signs that may indicate the need for ACL reconstruction. 

1. Persistent Knee Instability

One of the most telling signs of a torn ACL is a feeling that your knee is “giving out,” especially when:

  • Walking on uneven ground
  • Pivoting or changing direction
  • Climbing stairs

If your knee feels unstable even after rest or physical therapy, it may indicate that the ligament cannot heal on its own.

2. Ongoing Pain and Swelling

While some swelling is expected after a knee injury, it should gradually improve. If you’re still experiencing certain symptoms weeks later, you may be dealing with a more serious issue. Warning signs to watch for include:

  • Swelling that comes and goes
  • Pain during movement
  • Stiffness that interferes with movement

3. Limited Range of Motion

Do you struggle to fully bend or straighten your knee? A restricted range of motion can interfere with everyday activities like sitting, walking, or driving. This limitation may result from instability or internal damage caused by an ACL tear.

4. Difficulty Returning to Activities

If you’ve tried to return to sports or regular exercise but feel pain, weakness, or instability, your knee may not be strong enough to support those movements safely. This is especially important for athletes or active adults who rely on quick movements and balance.
