Knee Pain

Knee pain is often a loading problem, not just a knee problem. We find what is placing too much stress on the joint so you can squat, run, train, and move with confidence again.

WHEN THE KNEE STOPS TRUSTING THE MOVEMENT

PAIN CHANGES THE WAY YOU LOAD YOUR LEG

Knee pain can change how you squat, run, climb stairs, and train. Over time, you may start shifting away from the painful side, cutting movements short, or avoiding positions that no longer feel strong or stable.

Even when symptoms settle, they often return once activity increases again. That usually means the knee has not rebuilt the strength, control, or tolerance needed for the demands being placed on it.

We look at how your entire leg handles force so we can restore confidence in the movements that matter most to you.

We do not just calm the knee down. We rebuild its ability to handle load without hesitation.

YOUR APPOINTMENT STAYS FOCUSED ON YOU
You work directly with a licensed physical therapist for the full session, with a plan built around your movements, goals, and current level of activity.

SOUND FAMILIAR?

HOW KNEE PAIN INTERRUPTS YOUR MOVEMENT

Knee pain often becomes most noticeable when the joint has to absorb force, control your body, or produce power. These patterns can help reveal what the knee is struggling to handle.

PAIN ON STAIRS

A sharp ache going up or down stairs, especially near the kneecap. Often tied to how the knee controls load as the leg bends.

SQUATS FEEL UNEVEN

You shift to one side, avoid depth, or lose confidence near the bottom. The painful leg may not be accepting its share of the work.

STIFF AFTER REST

The knee feels tight after sitting, driving, or waking up, then improves once you move. Irritation and reduced joint tolerance may both contribute.

SWELLS AFTER ACTIVITY

Training feels manageable at first, but aching or swelling appears later. That often means the knee handled more stress than it was ready for.

THE ROOT CAUSE

WHAT WE TEST BEFORE BUILDING YOUR PLAN

01

HOW WELL YOUR KNEE ACCEPTS LOAD

We look at how the joint responds when you squat, step, land, and change direction, not just how it feels at rest.

02

WHETHER YOUR HIP CONTROLS THE LEG

Poor hip control can let the knee collapse inward or rotate under pressure, increasing stress during running, lifting, and sport.

03

HOW YOUR ANKLE AFFECTS YOUR KNEE

Limited ankle mobility can force the knee to compensate, especially during deep squats, stairs, and forward movement.

04

WHAT YOUR LEG CAN HANDLE RIGHT NOW

Pain often appears when activity exceeds your current capacity. We identify the gap, then rebuild strength and tolerance progressively.

CONDITIONS TREATED

KNEE CONDITIONS WE TREAT

A diagnosis may name the irritated tissue, but it does not explain why the knee keeps struggling under load. We treat the condition while rebuilding the strength, control, and capacity behind it.

LIGAMENT & MENISCUS-RELATED
ACL Injury MCL Injury LCL Injury PCL Injury Meniscus Tear Knee Instability
JOINT & KNEECAP
Patellofemoral Pain Chondromalacia Patella Knee Arthritis Patellar Tracking Issues Joint Stiffness Cartilage Injuries
TENDON, OVERUSE & POST-SURGICAL
Patellar Tendinopathy Quadriceps Tendinopathy Runner’s Knee Jumper’s Knee IT Band-Related Knee Pain Post-Surgical Knee Pain Recurrent Knee Pain Overuse Knee Injuries

THE RECOVERY PLAN

YOUR KNEE PAIN GAME PLAN

Four phases that take you from irritated and hesitant to strong, confident, and ready for full activity.

PHASE 01

SETTLE THE IRRITATION

Reduce pain and swelling while keeping the knee moving safely. Early treatment creates room to rebuild without constantly provoking symptoms.

PHASE 02

RESTORE RANGE

Regain the knee, hip, and ankle motion needed for stairs, squats, running, and everyday movement to feel natural again.

PHASE 03

REBUILD STRENGTH

Strengthen the quads, hamstrings, hips, and calves so the leg can absorb force without shifting stress back into the knee.

PHASE 04

RETURN TO DEMAND

Progressively reintroduce lifting, running, jumping, cutting, or sport until your knee can handle more than your routine requires.

COMMON QUESTIONS

KNEE PAIN QUESTIONS, ANSWERED

Do I need an MRI before starting physical therapy for knee pain? +
Usually not. A movement evaluation can show how your knee responds to squatting, stepping, running, and other activities that imaging cannot measure. If your symptoms, injury history, or examination suggest that an MRI or physician referral is appropriate, we will let you know.
Should I stop squatting or running if my knee hurts? +
Not necessarily. Completely avoiding activity can reduce the knee's tolerance over time. We help you adjust depth, volume, speed, or intensity so you can keep moving while gradually rebuilding the strength and capacity required for full activity.
Why does my knee hurt on stairs but feel fine while walking? +
Stairs place more demand on the knee than level walking because the leg must control and lift more of your body weight. Pain may be related to limited strength, reduced control, kneecap irritation, or the way your hip and ankle influence the movement.
Can physical therapy help a meniscus or ligament injury? +
In many cases, yes. Physical therapy can restore motion, improve stability, rebuild strength, and prepare the knee for running, lifting, or sport. Whether surgery is needed depends on the injury, your symptoms, and your goals, and we will coordinate with your physician when necessary.
How long until my knee starts feeling stronger? +
Some people notice improvements in pain or movement within the first few visits. Rebuilding enough strength and tolerance for stairs, deep squats, running, or sport usually takes longer. After your evaluation, we will outline a realistic timeline based on your starting point and goals.
Do I need a referral, and do you take insurance? +
In New Jersey and Pennsylvania, you can see a physical therapist directly in most cases. We work with many major insurance plans and offer straightforward self-pay options. Send us your information and we will verify your benefits before you begin.

I am so grateful I found the Next Level Team in Hamilton. I tried the traditional route and it didn’t work for me. I came to them with chronic back and knee pain and after seeing Dr. Erin for 4 months I feel like I can do a lot more and overall move so much better! Dr. Erin is the kind of tough you need, very smart and easy to get along with! My experience has been very enjoyable and I am really happy with my progress thus far.

I highly recommend Next Level Physical Therapy. I worked with Dr. Rich for knee pain and he was excellent. As an active 60+ year old having pain in both knees I came looking for a program to address anything that might be causing the pain - I was hopeful it wasn't normal wear and tear. Sure enough Dr. Rich was able to identify movement patterns and areas in my body that were causing problems in my knees. With Dr. Rich's guidance and plan I was able to achieve my goal of exercising without knee pain and kneeling with my hips against on my heals - something I wasn't able to do before. Thank you Dr. Rich and Next Level!

For about 4 years, I have been experiencing terrible (left) knee pain. I started to develop an obvious bump under my knee cap. I saw many doctors, had x-rays and mri’s done. Scripts for Physical Therapy were ordered, and I went for weeks. But the pain persisted, and the bump grew. I stopped all my favorite activities (tennis, pickleball, walking, burpees, squats, lunges, avoided stairs, etc.) and sat around resting my knee for a few weeks feeling hopeless. Majority of my time I spent surfing YouTube videos. An advertisement kept popping up by Dr. Mike @Next Level Physical Therapy of Mercer County. I skipped the ad many times until one day I heard the words “active adult experiencing ongoing pain….” And I finally stopped and watched and listened to the whole video. Dr. Mike described me! At this point I had nothing to lose so I called Next Level for an assessment. BEST decision ever!!! I was introduced to Dr. Cole Housel for my assessment and my life would be forever changed. Dr. Cole took his time to get to know me and my goals for my active lifestyle. After the physical assessment he told me two pieces of good news. The first, was that I did not need surgery! The second, he identified the problem and was confident he could help me get rid of my knee pain. YAY! I was so elated and now hopeful for the first time in a long time. He taught me that my knee was compensating for an issue with my hip. At every session, Dr. Cole listens attentively to me, is always positive even when I am not, and takes an interest in my life especially my passion for Pickleball. I truly believe I would not have won a tournament medal without Dr. Cole teaching me how to move my body safely and effectively. When we first started, I just wanted to stop suffering and start moving again. Working with Dr. Cole, I learned so much about body movement. I feel like I gained a supportive friend who keeps me focused and motivated to achieve the best injury free active lifestyle. Please, if you are in pain and want to keep moving, work with Dr. Cole Housel. He really is an expert in his field and understands how the human body should move. --------------------------------------------------------------------------------------------------- UPDATE: August 2026 Back again! This time to rehab a broken ankle. Another fantastic experience with Dr. Joe Risoli. He created a custom recovery plan, explained each exercise with video examples so I can do work at home and he got me out of my boot in record time which made me so happy! I am able to get back to all the things I love to do like playing pickleball. Also, Jenn who works the front desk was very friendly and professional. Next Level Physical Therapy Hamilton office is clean, bright, well equipped and has the best staff!

’m very pleased with the physical therapy I received from Dr Dan for my knee. Before starting therapy, I was experiencing significant knee pain that made walking and everyday activities more difficult. Through the exercises, treatments, and guidance provided by the physical therapist, I have noticed a significant improvement in my pain and mobility. Dr Dan was professional, patient, and encouraging throughout the process. He took the time to understand my condition and worked with me to develop exercises that helped strengthen my knee and other areas around my knee which significantly improve my movement. I’m very happy with the progress I’ve made and would recommend this physical therapy team to anyone dealing with knee pain or mobility issues. The treatment has made a noticeable difference in how I feel and move.

Dr. Erin at Next Level Physical Therapy helped me recover from decades-long issues in a way I didn’t think was possible. As a former competitive distance runner, my body had developed suboptimal movement patterns that felt set in stone due to years of repetitive stress. I had previously seen many physical therapists who either couldn’t identify or couldn’t fully resolve the underlying dysfunction. What sets Dr. Erin apart is her ability to truly listen to her patients and synthesize that feedback with diagnostic movement tests to determine what exercises need to be done and in what order. Not only do I now move more symmetrically, but the knee pain that had plagued me for nearly a decade is gone. I finally understand how to avoid falling back into old patterns, and I see a clear pathway for staying active as age. Thank you Dr. Erin!

I came in at the beginning of this summer needing to rehab my Achilles for the football season this upcoming fall. They set me up with Erin, who not only helped me gain my confidence and strength back in my calf and foot. But also cleared up my lingering back and knee pain. I was always walking out of there feeling better than I did the last session, and I can't thank Erin enough for the knee and back pain that have been around for YEARS. So blessed to have a place like this near me. 5 Stars.

Dr. Elyse has been great, informative, helpful and supportive during my time so far at next level physical therapy. From helping with my knee pain, to understanding the root cause of it all to avoid future injuries have been very educational and I’m so grateful. When working out, I’m finally able to understand form, assess any pain I may potentially feel in the moment and enjoy the rest of my session oppose to having to compensate and feel defeated. I’m truly excited to get stronger and see what the future holds in my gym journey. -shea

Next Level Physical Therapy is the real deal. Dr. Matt Simcox is truly next level in his care and attention for his clients. He is professional and relates well to his clients. He goes the extra mile and he knows his stuff. My high school daughter was having knee pain and some ankle pain. We went to Next Level Physical Therapy for the free evaluation. Dr. Matt was very thorough and walked us through everything he was doing. He explained how the body was connected and as a result of my daughter's previous injuries and hip misalignment, the knees were overcompensating. Her hips, knees, and ankles were out of whack. Since she is a track athlete and was in the middle of the season, so he developed a 11 week plan tailored to her specific issues. He asked her what her goals were and came up with a plan to help her achieve those goals. She started out with minimal hip rotation, pain in her knee, and ankle stiffness. She had plateaued in her running events. Through a combination of his expertise, soft tissue techniques, exercises, etc, Dr Matt found what worked for our daughter and what her body responded to. Each session he took time to see how her day or weekend was, kept her engaged, and connected with her. Every week he sent messages seeing how she was doing and asking about her track meets. It was such a personal touch and let me know that he truly cared about our daughter as a person. He remembered details about her and encouraged her. Even when she injured her other knee, he brought us in to check her out and swiftly shifted to addressing the new injury. She had 5 days before a major competition and we weren't sure she would be able to compete. However, Dr. Matt identified the issue, came up with some solutions and exercises to help her body quickly respond so that she would still be able to compete. This was a major blessing because she would have been devastated if she couldn't compete. At the end of the 11 weeks, my daughter met her goals. She qualified for Districts and New Balance Nationals. She no longer has pain in her right knee and her hips are better aligned. She ran her PR in 2 events and got her PR, breaking her school record in the long jump. After each week, she was making significant progress at her meets. This would not have been possible without the help of Dr Matt. We are thankful. It was well worth the investment. I highly recommend Dr. Matt Simcox at Next Level Physical Therapy. He rocks!

I’ve been going to Next Level for about a year now, and working with Dr. Devi has honestly been life-changing. I originally started PT because I was dealing with really bad knee pain and sciatica. After just a few sessions with Dr. Devi, my pain improved so much. She not only helped me get out of pain, but she also created a program to help me get stronger and make sure the pain didn’t keep coming back. Even after my knee and sciatica improved, I kept going because she helped me work toward other strength and fitness goals. She’s incredibly knowledgeable, patient, supportive, and always takes the time to explain things. She pushes you to improve while making sure you’re doing things safely and not getting injured. What I appreciate most is that she genuinely cares about her patients. She’s not just focused on treating the problem. She wants to help you get stronger, move better, and be more active overall. Before coming to Next Level, I went to another PT clinic for 9 months and saw very little improvement. The one on one sessions with Dr. Devi made such a huge difference. Having personalized attention and feedback is completely different from the groups PT I experienced before. I’m so glad I found Dr. Devi and Next Level. I can’t recommend them enough!

I've been working with Meghan for knee pain and can't recommend her enough. In less than a year, my pain is almost completely gone, even though I've actually increased how much I'm moving and exercising. Beyond the physical results, the biggest thing I've taken away is a much deeper understanding of how my body works. I now go to the gym with so much more confidence about what I'm doing and why, instead of just guessing. Huge thanks to Meghan and everyone else working at Next Level!!
