Top Exercises to Prevent Knee Pain and Injuries: A Physical Therapist’s Guide

As you know living in Merrick, NY, we are spoiled to have a great selection of trails and places to hike, run, and walk. Whether it is a gorgeous day out at Norman J. Levy Park or just a stroll around the neighborhood, we try to stay as active as possible. But what about that nagging twinge in your knee that makes you think twice about your next adventure? Sound familiar? We see this so often with our patients. It is an “ouchy” sensation when you bend over, or a dull ache that sticks around after a long hike. It is easy to think “Well, I guess this is just what happens when you get older or stay active.” Or maybe you heard that old wives’ tale: a little pain means a little gain. But what if that’s just a myth?

Take a moment to think about your knee. This joint is truly an engineering marvel; however, it is also positioned between two VERY challenging neighbors. Above it is the highly mobile, ball-and-socket joint of the hip and below the shock-absorbing and multi-planar foot and ankle. The knee is meant to be a rock solid, mostly bending and straightening hinge. The trouble usually starts above and below in the hip and foot. Weakness or dysfunction in the form of poor mechanics or muscle control in these areas means more stress and force is placed on the knee.

The good news is that you do not have to just resign yourself to this. We feel it is very important for you to know that discomfort is NOT a normal or necessary part of being active. You can take charge. You can absolutely take control of your joint health. With an understanding of how your body moves and a commitment to a few specific, targeted knee pain exercises, you can build a more solid foundation. That is our goal for you with this article, to educate and empower you with the knowledge and tools you need to prevent knee pain.

Before we get into a specific program to prevent knee injuries let’s first discuss why knee injuries even occur.

Understanding Why Knee Injuries Occur

Let’s start with a basic principle of problem-solving. To fix a problem you must first understand the cause. Pain or injury in the knee rarely just happens without reason. Imbalances and faulty movement patterns over time are the main culprits we see as physical therapists.

A large number of knee problems actually start one joint above: the hips. In particular, we see a lack of strength in a specific hip muscle called the gluteus medius on a very regular basis. This muscle on the outside of your hip is responsible for keeping your pelvis level and controlling the position of your thigh bone. Without this muscle working properly your thigh bone drifts and rotates inward, which makes your knee collapse into a “knock-kneed” position as you are hiking, squatting, or stepping down stairs. In fact, this is an extreme amount of stress on the inside part of your knee.

Knee injuries can also start from the ground up. Poor foot mechanics, such as flat arches that roll inward, cause your shin bone to rotate inward. The knee is where the thigh bone and shin bone meet, so with rotation from your foot and poor control in your hip, this sets up a lot of twisting force through the knee. Proper foot support and hip strengthening is foundational in preventing knee pain.

In general, knee injuries are broadly broken into two categories. Acute trauma and overuse injuries. Acute trauma is what most people think of when they hear the word “injury.” A tear in a ligament, a structure that holds the joint together due to a twisting accident on the trail. Although the strong muscles we are discussing help to protect the knee joint, people can and do get unlucky. Overuse injuries are almost 100% preventable and are the issues that tend to develop over weeks or months. Think runner’s knee, IT band syndrome, or that nagging ache after a long hike. These injuries are due to repetitive micro-trauma. That is a fancy way of saying that every step with poor mechanics you place a tiny amount of stress on the tissues of the knee. Over thousands of steps that add up and result in inflammation. This is why a proactive program is so important. It helps you correct these faulty movement patterns and prevent knee pain before it can become a chronic problem.

Essential Warm-Up Exercises for Knee Pain

Have you ever tried stretching a cold rubber band? Cringe-worthy, right? It is stiff and can even snap. Your muscles and joints are the same way. They need to be properly warmed up and prepared before you go out for a hike or run. Jumping right into a hike or run without properly preparing the body is the exact opposite of what you should be doing to prevent knee pain.

The primary purpose of a warm-up is to increase the blood flow to your muscles and prepare the nervous system for the activity ahead. The increased blood flow raises the temperature of the tissues, making them more pliable and less likely to be injured. We are a fan of dynamic over static stretching before activity. This means moving your joints through their full range of motion in an active way. This can be as simple as leg swings, high knees, or walking lunges. A warm up also helps circulate the natural lubricant within the knee joint. At a minimum, five minutes of dynamic warm up should be non-negotiable for any type of workout.

The Best Exercises to Prevent Knee Pain and Injuries

Now we get into the fun part. We have chosen 4 exercises below that we utilize frequently in our clinic. This is not a random selection. These exercises were chosen because of how they target the causes of most non-traumatic knee pain. There are many exercises in the world and while variety is important for a complete program, we believe the exercises in this list to be most essential and specifically targeted to prevent knee pain and injuries.

1. Straight leg raises

Strength training with a sensitive knee can sometimes feel like the last thing you want to do because it can feel like your knee is getting hammered. The straight leg raise is a great exercise because it allows you to specifically target the strength of the quadriceps (the muscle on the front of your thigh) without any compressive force through the knee.

Setup: Lie on your back and bend one knee and place your foot flat on the ground. Keep the other leg straight.

Key Cues: Squeeze or tighten the thigh muscle on the straight leg. Slowly lift the straight leg to the height of your other knee and slowly lower it back down.

This exercise is a foundation to help prevent knee pain and re-establish muscle control.

2. Clamshells

As we mentioned above, weak hips are one of the main reasons for knee problems. The clamshell exercise is the classic go-to exercise to target the glute (butt) muscles and “wake them up.”

Setup: Lie on your side with your legs stacked and knees bent.

Key Cues: Keeping your feet together, lift your top knee toward the ceiling without rocking backward. The movement should come only from your hip.

Strong hips are the best offense to help prevent knee pain and injuries.

3. Squats (knee tracking)

Squats are not just a gym exercise. We are built to squat. Squatting is a fundamental human movement. We squat to sit down, to pick things up, and to get up from the floor. The squat pattern is essential to master with good form to prevent knee pain and injuries.

Setup: Stand with your feet about shoulder width apart with your toes facing forward or slightly outward.

Key Cues: Initiate the movement by sitting back with your hips like you are trying to sit in a chair. As you squat down, make sure that your kneecaps are tracking in line with the middle of your toes and not caving in.

Think of this sequence as an athletic hinge, a concept we will discuss in another blog post.

4. Hamstring curls

We commonly see a major imbalance between the strength of the front thigh muscles versus the back thigh muscles. The hamstring curl targets those important muscles on the back of your thigh.

Setup: Stand and hold onto a countertop or other surface for balance.

Key Cues: Keeping your thighs parallel, slowly bend one knee to bring your heel up toward your buttock. Squeeze the muscle on the back of your thigh and then slowly lower your foot back down.

Muscle balance is key in preventing knee pain.

When to See a Physical Therapist in Merrick, NY

The above prevention program is one that we strongly believe in and can do amazing things. But sometimes the path of self-care is not enough. Sometimes you must know when to ask for professional help. A few big red flags to look out for are major swelling in the knee especially after activity, mechanical symptoms like clicking, locking, or the knee feeling like it is “giving out” or buckling. These are signs that you may have structural damage and it is time to seek out professional help.

If any of those symptoms sound familiar, we are right here to help. A generic program is a great starting point, but it does not take into account your body’s specific structure and mechanics. Here at Summit Physical Therapy, we start every client with a full biomechanical assessment. We do not just look at your knee, we look at your hip mobility, your ankle flexibility, your foot posture, and many other aspects of how your body moves. A physical therapist in Merrick can then create a program that is specifically for you and targets your specific weaknesses.
