Physical Therapy for Knee Pain in NJ That Actually Works
At Iron Physical Therapy, you won’t get a generic plan or be told to “just rest.” You’ll get one-on-one care from a Doctor of Physical Therapy who understands how important movement is to you. We take time to find the real reason your knee hurts and build a plan that fits your lifestyle, not the other way around.
At our Caldwell and Midland Park clinics, we help athletes, weekend warriors, and active adults recover from knee injuries, surgery, and overuse pain. With hands-on care and smart strength training, we’ll help you move better, perform better, and get back in the game.
Why does my Knee hurt?
Knee pain can come from sudden injury, old wear and tear, or poor movement patterns that build up over time. Our physical therapists look beyond symptoms to find the source, whether it’s a joint, muscle, or alignment issue.
Sports injuries: Sprains, strains, or ligament tears from running, cutting, or twisting. See how we treat sports injuries here.
Patellofemoral pain syndrome (runner’s knee): Pain around or behind the kneecap caused by muscle imbalance or poor tracking.
Meniscus tears: Damage to the knee’s cartilage that can cause locking or swelling.
Tendonitis or overuse: Repetitive stress that leads to inflammation and stiffness.
Arthritis: Chronic inflammation that makes the joint stiff, painful, or swollen.
Bursitis: Irritation of the small fluid sacs that cushion the knee.
Post-surgical recovery: Weakness, stiffness, or pain after ACL, meniscus, or total knee procedures.
Movement or strength imbalance: Weak hips or tight quads that overload your knees during activity.
Whether you’re recovering from knee surgery (like ACL repair, meniscus repair, or total knee replacement) or trying to avoid one, our team can help you rebuild mobility, strength, and confidence in your knee.
Common Signs & Symptoms of Knee Pain
Knee pain can affect your workouts, daily movement, and even your confidence. You might notice:
Sharp pain when walking, squatting, or climbing stairs
Stiffness or aching after sitting or standing
Clicking or grinding in the joint
A popping sensation in the knee area
Swelling or tenderness around the knee
Weakness or instability, like the knee might “give out”
Pain that worsens with workouts or cold weather
Trouble fully bending or straightening your leg
If these sound familiar, schedule an evaluation at our Caldwell or Midland Park clinic. We’ll help you find lasting relief and rebuild strength that lasts.

Often, yes! The key is knowing how. We’ll guide you through safe, targeted movement that builds strength and confidence while avoiding setbacks.

It depends on your injury and goals. Our therapists create individualized return-to-sport plans so you recover fully, not just quickly.

Real Stories: How Our Patients Got Back After Knee Injury
Tracy, Active Mom
“Physically, I feel like I'm in better shape than before I went into surgery because Iron PT incorporated a lot of challenging strength training into my therapy.
Mentally, I had some low points where I feared I wasn't going to function well again, but my DPT really elevated my spirits (or simply refused to let me stay down!) and helped me to keep my eye on the end goal. Whenever I was feeling low, I knew I'd feel better after I went to physical therapy.”
William, Runner & Dad
“I have been to going to physical therapists for most of my athletic life, and Iron PT is the first place interested in treating the sum of the parts. They taught me that the knee functions only as well as the muscles and tissue that connect to it. My legs have become stronger, I have become stronger, and for the first time in my life, I am looking forward to a summer without pain.”
Katie, Yoga Instructor
“The Iron PT staff truly created a safe and supportive environment in which I could test my limits while strengthening and healing my injury. My DPT also provided me with tools I can use outside of therapy such as stretching, foam rolling, and targeted strength training exercises to help maintain a healthy and happy knee.”
