Pickleball Knee Pain: Three Causes and What Fixes Them
July 29, 2026
Most players assume knee pain is just the cost of playing. Usually it isn't. Here's what's actually happening, and what to do about it.
The elbow gets more attention because it has a catchy name. But talk to a room full of recreational players and the knees come up first, more often, and with more resignation. Most players assume it is simply the cost of playing a court sport after 50.
Some of it is. Most of it is not. Knee pain in pickleball is usually a mechanical problem rather than a wear-and-tear problem, and mechanical problems can be changed.
What Pickleball Actually Does to a Knee
The knee is built to move well in one plane, forward and back. It is far less comfortable with rotation and side-to-side loading, and pickleball is full of both.
Three movement patterns account for the majority of knee load in the sport:
- The split step and lateral push-off. Decelerating sideways loads the knee at an angle it does not naturally prefer, repeatedly, hundreds of times per session.
- The dinking crouch. Sustained partial knee flexion holds the quadriceps under constant tension and compresses the kneecap against the femur for extended periods.
- The lunge for a low ball. A deep, fast, often unbalanced knee bend under load, frequently with the knee tracking inward.
None of these are inherently damaging. They become damaging when the muscles that are supposed to control them are not strong enough to do so, which is where most knee pain originates.
The Three Most Common Sources
1. Patellofemoral Pain (Pain Around the Kneecap)
The most common presentation by a significant margin. It feels like a dull ache around or behind the kneecap, worse on stairs, worse after sitting for a while, and worse during the dinking game specifically.
The mechanism is tracking. The kneecap glides in a groove on the femur, and it is guided there by the balance of pull from the quadriceps and the alignment of the hip above it. When the outer quad overpowers the inner quad, or when weak glutes let the knee drift inward during lateral movement, the kneecap tracks slightly off-center and the contact pressure concentrates rather than distributes.
The critical insight, and the one most players miss: this is usually a hip problem presenting at the knee. Weak glute medius allows the femur to rotate inward, and the kneecap follows.
2. Patellar Tendinopathy (Pain Below the Kneecap)
A sharper, more localized pain directly on the tendon between the kneecap and the shin bone. It hurts when you press on it. It is worst at the start of activity, sometimes eases as you warm up, and returns worse afterward.
This is a load-tolerance problem. The tendon is being asked to absorb more repetitive jumping and decelerating force than it has adapted to handle. Tight quadriceps make it substantially worse by increasing baseline tension on the tendon, which is why quad stretching matters more here than almost anywhere else.
3. IT Band Irritation (Pain on the Outside of the Knee)
A tight, burning sensation on the outer edge of the knee, common in players who do a lot of lateral shuffling. The iliotibial band runs from the hip down the outside of the thigh and inserts just below the knee, and when the hip muscles that attach to it are tight or overworked, tension increases along its entire length.
Again, the origin is the hip. Treating the outer knee directly rarely resolves it.
| Where It Hurts | Likely Source | Worst During |
|---|---|---|
| Around or behind the kneecap | Patellofemoral tracking | Stairs, dinking, after sitting |
| Directly below the kneecap | Patellar tendon | Start of play, jumping, after play |
| Outer edge of the knee | IT band tension | Lateral shuffling, long sessions |
| Inner side of the knee | Medial structures | Pivoting, twisting |
| Deep inside the joint, with swelling | Needs evaluation | Varies |
Swelling inside the joint, a knee that locks or catches, a sensation of the knee giving way, or an inability to fully straighten it are all signals that something structural may be involved. Those are not managed with stretching and a change in playing volume. See a professional.
What Actually Helps
Strengthen the Hips Before the Knees
This is the highest-return change available and the one players most consistently skip. Glute medius strength controls femoral rotation, which controls knee tracking. Side-lying leg raises, lateral band walks, and single-leg glute bridges, two to three times per week, address the root of both patellofemoral pain and IT band tension.
Build Quadriceps Capacity
Stronger quads absorb more of the deceleration force that would otherwise reach the tendon and joint. Wall sits, step-downs, and controlled bodyweight squats within a pain-free range build tolerance. Note the qualifier: within a pain-free range. Working into pain sets tendons back rather than forward.
Stretch the Quads and Hip Flexors Daily
Tight quadriceps directly increase tension on the patellar tendon and increase compression at the kneecap. Tight hip flexors alter pelvic position and change how the knee tracks. These are two of the highest-yield stretches available to a pickleball player and they take four minutes.

Fix the Footwear
Court shoes, not running shoes. Running shoes are built for forward motion and offer minimal lateral support, which allows the foot to roll and sends rotational force up the chain into the knee. This is a genuinely common and completely avoidable contributor.
Manage Volume
Knee tissue adapts to load like everything else, and load-related knee pain frequently resolves on its own when weekly volume drops for a few weeks while strength work builds capacity. [INTERNAL LINK → How Often Should You Play Pickleball? A Frequency Guide by Age and Level]
The Post-Session Routine
-
Apply a topical balm to the knee within the first 30 minutes
The cooling sensation from menthol and camphor is noticeable within a minute or two on a knee that has been working. Do it before you shower and before you sit down.
-
Stretch the quads and hip flexors while still warm
Forty-five second holds, both sides, both muscle groups. This is the window where static stretching produces the most change.
-
Ice if there is any swelling
Fifteen to twenty minutes. Only if swelling is actually present. General soreness without swelling does not require it.
-
Keep moving in the evening
A short walk maintains circulation to the joint. Sitting still for four hours after a session reliably produces a stiffer knee the next morning.

Paddle Pro™ Organic Recovery Balm is built for exactly this part of the routine, applied to the knee right after you set your paddle down, before you shower or sit down.
Shop the Balm- Most pickleball knee pain is mechanical rather than degenerative, which means it responds to changes in strength, mobility, footwear, and volume.
- Pain around the kneecap and pain on the outer knee both usually originate at the hip. Glute strength controls knee tracking.
- Pain directly below the kneecap indicates patellar tendon load intolerance, and tight quadriceps make it substantially worse.
- Swelling inside the joint, locking, catching, or giving way are structural signals that warrant professional evaluation rather than self-management.
Published injury surveillance data indicates that knee injuries account for roughly 19 percent of pickleball-related emergency department visits, placing them among the most frequent presentations in the sport. Separately, the sports medicine literature on patellofemoral pain has consistently found that hip-focused strengthening programs, particularly those targeting the hip abductors and external rotators, produce greater reductions in knee pain and better functional outcomes than knee-focused exercise alone. The mechanism is straightforward: controlling femoral rotation at the hip controls patellar tracking at the knee.
Frequently Asked Questions
Why do my knees hurt after playing pickleball?
The most common causes are patellofemoral tracking issues, where the kneecap does not glide cleanly in its groove, patellar tendon overload from repetitive deceleration, and IT band tension from lateral movement. All three are mechanical rather than degenerative in most players, and all three are strongly influenced by hip and quadriceps strength. Footwear matters as well: running shoes lack the lateral support that court movement requires.
Should I wear a knee brace for pickleball?
A neoprene sleeve provides mild compression and improves proprioception, meaning your nervous system's awareness of joint position, which many players find helpful during play. It does not correct the underlying mechanical cause. A sleeve is a reasonable supportive measure alongside strength work, but relying on it as the sole intervention tends to postpone rather than resolve the problem.
Can I keep playing pickleball with knee pain?
Often yes, with modifications. Reduce session length, lower the intensity, and avoid the specific movements that reproduce the pain while you build hip and quadriceps strength. Complete rest is rarely the best approach for load-related knee pain, because tendon and joint tissue lose capacity quickly without stimulus. Pain above roughly 4 out of 10 during play, or pain that increases session over session, means the modifications are not sufficient yet.
Is pickleball bad for your knees?
Pickleball is lower-impact than tennis, basketball, or running, and the smaller court reduces total distance covered. For most players it is one of the more knee-appropriate court sports available. The knee complaints that do arise are usually driven by insufficient hip and quadriceps strength, inappropriate footwear, or a sudden increase in playing volume rather than by the sport itself.
