Pickleball Injuries: How to Protect Your Knees

Pickleball is officially the fastest-growing sport in America. With millions of players grabbing paddles every year, physical therapists are seeing a massive spike in a specific problem: knee injuries. If you want to stay safe on the court and avoid sitting out for months, protecting your joints requires preparation and the right routine.

Why Pickleball is Tough on Your Knees

At first glance, pickleball looks like a low-impact activity. You play on a smaller court than tennis, and the paddle is light. However, the game requires constant starting, stopping, and pivoting. These sudden, explosive movements put intense pressure on your knee joints.

Most games take place on hard surfaces like concrete or asphalt. These hard courts offer zero shock absorption. Every time you lunge forward to return a drop shot at the kitchen line, your knees absorb the impact. Over time, this repetitive stress leads to common injuries. Players frequently suffer from patellar tendinitis (often called jumper’s knee), meniscus tears, and medial collateral ligament (MCL) sprains.

To keep your knees healthy, you need a proactive approach that includes targeted warmups, proper footwear, and strength training.

Dynamic Warmups Designed for Pickleball

The snippet of advice every sports doctor agrees on is to stop doing static stretches before you play. Touching your toes and holding the position for thirty seconds does not prepare your muscles for a fast-paced game. Instead, you need a dynamic warmup. Dynamic warmups increase blood flow and mimic the specific movements you will make on the court.

Plan to spend five to ten minutes doing the following exercises before you even pick up your paddle:

Lateral Shuffles: Pickleball requires constant side-to-side movement. Stand with your knees slightly bent and step out to the right, bringing your left foot to meet it. Shuffle from one sideline to the other and back again. This activates your outer thigh muscles and stabilizes the knee joint.
Walking Lunges: Step forward with one leg and lower your hips until both knees are bent at a 90-degree angle. Push off your back foot to step forward into the next lunge. Walk from the baseline to the net twice. This warms up your quadriceps and glutes.
Leg Swings: Find a fence or net post for balance. Swing one leg forward and backward ten times, then side to side ten times. Repeat on the other leg. This opens up your hips, which takes rotational pressure off your knees.
High Knees: Jog in place while bringing your knees up toward your chest. Do this for thirty seconds to elevate your heart rate and loosen the joints.

Stop Wearing Running Shoes on the Court

One of the easiest ways to injure your knee in pickleball is wearing the wrong shoes. Running shoes are built for forward motion. They have high heels and thick, gripping treads designed for running in a straight line.

If you wear running shoes on a pickleball court, the thick tread can catch on the hard surface when you try to shuffle sideways. When your shoe stops but your body keeps moving, your knee twists. This exact scenario is a leading cause of meniscus tears on the court.

You need a dedicated court shoe. Court shoes have flatter soles, rounded edges, and heavy lateral support to keep your foot stable during side-to-side movements. Brands like K-Swiss (specifically the Hypercourt Express 2) and Asics (like the Gel-Resolution 9) design shoes specifically for the lateral stresses of racket sports. Investing in a 100-dollar pair of court shoes can save you thousands of dollars in medical bills.

Essential Strength Training for Knee Stability

Your knee is a hinge joint held together by ligaments and supported by the muscles around it. If your quadriceps, hamstrings, and glutes are weak, your knee joint takes the brunt of the impact. Building strength in your legs is the best long-term strategy for injury prevention.

You do not need a gym membership to build leg strength. Try adding these simple exercises to your weekly routine:

Wall Sits: Press your back flat against a wall and slide down until your knees are bent at a 90-degree angle. Hold this position for 45 seconds to one minute. This builds isometric strength in your quadriceps.
Goblet Squats: Hold a 10-pound or 15-pound dumbbell close to your chest. Lower your hips back and down as if you are sitting in a chair. Keep your chest up and push through your heels to stand back up. Aim for three sets of twelve repetitions.
Glute Bridges: Lie on your back with your knees bent and feet flat on the floor. Squeeze your glutes and push your hips up toward the ceiling. Hold for two seconds at the top, then lower down slowly. Weak glutes force the knees to cave inward during play, so strengthening your backside is crucial.

Support and Recovery

If you already have a history of knee pain, wearing a knee brace during play provides valuable mechanical support and psychological confidence. You do not necessarily need a heavy, rigid brace. A compression sleeve, like the Bauerfeind Sports Knee Support or a simple DonJoy compression sleeve, increases blood flow and helps your brain sense the position of your knee joint.

Recovery is just as important as the warmup. After a tough match, grab an ice pack. Applying an ice wrap from a brand like Hyperice or FlexKold for 15 minutes reduces inflammation. Additionally, taking one or two rest days between heavy playing sessions allows your tendons and ligaments time to repair themselves.

Frequently Asked Questions

Should I wear a knee brace while playing pickleball? If you have a history of knee pain or instability, a compression sleeve or mild support brace is a great idea. It provides stability and keeps the joint warm. However, a brace should not replace a good strength training routine and proper court shoes.

Can I play pickleball if I have bad knees? Yes, but you need to be cautious. Play doubles instead of singles to reduce the amount of court you have to cover. Stick to softer surfaces like indoor wooden gym floors if possible, and always clear your physical activity with an orthopedic doctor first.

Why do my knees hurt after playing pickleball? Knee pain after playing is usually caused by the impact of the hard court, quick pivoting motions, or wearing improper shoes. The pain is often inflammation in the patellar tendon or mild irritation in the joint space. Stretching your leg muscles after you play and applying ice can help manage post-game soreness.
