Knees and pickleball: protecting the joint that does all the work
Pickleball is marketed as a low-impact sport, and compared to tennis or basketball, it is. But it’s not no-impact, and for players over 55 — especially those with prior knee issues — the knee is the most commonly injured joint after the elbow. The good news is that most pickleball knee pain is preventable or manageable with smart habits. The less-good news is that many players ignore early warning signs and end up needing a surgery that could have been avoided.
What pickleball actually asks of your knees
The movements that stress your knees most in pickleball:
- Lateral shuffling — moving sideways at the Kitchen line. This is constant.
- Sudden direction changes — pivoting to chase a lob or track a cross-court ball.
- Stop-and-start sprints — forward to the Kitchen, backward to defend, forward again.
- Deep knee bends — getting low to dink, volleying from a bent position.
- Impact from jumping and landing — overhead smashes, Ernes, the occasional lunge.
None of these are extreme by sports standards. A singles tennis match is much harder. But multiplied over two hours, three days a week, they add up — especially on knees that have lost some cartilage from 60+ years of use.
The five things that protect your knees
1. Court shoes, not running shoes
Running shoes are built for forward motion. They have soft, shock-absorbing soles that feel great when running but roll under lateral pressure, which twists the knee. Court shoes (tennis, volleyball, pickleball-specific) have a flatter, stiffer sole built for sideways movement. The difference in knee stress is real and measurable.
If you play pickleball in running shoes, your knees are working harder than they need to — and falls are more likely. See the court shoes and falls wiki page for details.
2. A proper warmup
Cold joints are stiff joints. A stiff knee under sudden lateral load is how meniscus tears happen. Five minutes of dynamic warmup before every session — leg swings, walking lunges, side shuffles, body-weight squats — preps the joint for the work ahead.
The warmup routine wiki page has a specific sequence. Do it every time.
3. Good lateral technique
Many players shuffle with their knees locked and their feet flat. This transfers impact directly to the knee joint. Better technique:
- Knees slightly bent, always — even at rest.
- Push off with the inside of your trailing foot, not the ball of your foot.
- Short steps, not long lunges.
- Keep your weight over your feet, not leaning out over your front foot.
Think of lateral movement like shuffling cards — small, controlled, balanced. Big lunging steps put much more stress on the knee than several small shuffles covering the same distance.
4. Strength training off the court
This is the single most-underused tool for knee health over 55. Strong quadriceps and strong glutes protect the knee joint by absorbing load that would otherwise go into the ligaments and cartilage. A simple routine — body-weight squats, step-ups, glute bridges, and single-leg balance work — done 2–3 times a week, adds years to your knees.
You don’t need a gym. You don’t need weights. Twenty minutes a session. The return on investment is enormous.
5. Rest days
Like the elbow, the knee doesn’t recover during play. At least one full rest day per week. Two is better if you’re playing intensely. If your knees ache into the next day, extra rest is mandatory, not optional.
Warning signs to take seriously
Some knee sensations are normal. Others are not. Here’s how to tell the difference.
Normal (don’t worry):
- General muscle soreness the morning after a hard session.
- A little stiffness in the first few minutes of play that warms out.
- Mild achiness after playing in cold weather.
Not normal (stop playing and see a doctor):
- A popping or tearing sound during play.
- Sudden swelling after a twist or impact.
- A knee that “gives way” or feels unstable under load.
- Locking — the knee catches and won’t move smoothly.
- Sharp, consistent pain that doesn’t fade with rest.
- Pain that wakes you up at night.
The not-normal list is not a list of “minor concerns.” Those are signs of structural injury to ligaments, meniscus, or cartilage. Playing through any of them makes the problem much worse. Stop, ice, elevate, and call a doctor.
If you already have a knee issue
You can still play pickleball. Millions of people with arthritic knees, repaired ACLs, meniscus trims, and even partial knee replacements play regularly. The modifications:
- Play on softer courts when possible. Wooden gym floors and cushioned tennis courts are easier on knees than asphalt. Indoor tends to be better than outdoor.
- Play doubles, not singles. Less court to cover, less movement, less stress.
- Stay at the Kitchen line. The more you move, the more load on the knee. Good positioning is knee-friendly by nature.
- Consider a knee sleeve or brace. These don’t “protect” the knee in the structural sense, but they improve proprioception (your body’s awareness of joint position) and reduce swelling after play. Worth trying.
- Shorter sessions. 60 to 90 minutes, not 2+ hours.
- Warm up longer than the standard 5 minutes — 10 to 15 minutes if you’ve had knee surgery or ongoing issues.
- Work with a physical therapist who understands recreational sports. A good PT can give you a targeted strengthening program that makes pickleball safe for your specific knee.
When to stop playing (permanently)
Rarely — but it happens. If your doctor or orthopedic surgeon specifically tells you that lateral court sports are damaging a joint beyond repair, listen. Pickleball is fun, but it’s not worth an irreversible injury. There are other ways to stay active that are kinder to the joint: swimming, cycling, walking, rowing.
Most players never hit that point. Most players who listen to their bodies and modify appropriately can play into their 80s. The ones who push through pain and never adjust are the ones who quit the sport in their 60s against their will.
Take care of your knees. They’re the joints doing all the work.
