If you’ve got a knee pain young athlete at home, it can mess with your whole week. One day they’re fine. The next day they’re limping after practice, pointing at their knee, and asking if they can skip stairs. As a parent, your brain goes straight to the scary stuff. Is it a real injury? Is it “just growing pains”? Do we shut them down… or push through?
Here’s the good news: a lot of youth knee pain is common and treatable. The trick is knowing which kind of pain you’re dealing with, and what to do next. Let’s break down osgood schlatter, patellofemoral pain, and even heel pain like Sever’s disease—plus when it’s normal growth vs. something you should get checked.
Background: Why kids get “growing pains knee sports”
Kids aren’t just small adults. Their bones, tendons, and muscles grow at different speeds. During growth spurts, bones can lengthen fast, while muscles and tendons feel “tight” and get pulled harder.
That’s why many overuse problems show up in ages 10–15, right when sports get more serious and bodies change fast.
Overuse vs. injury (simple difference)
- Overuse = the same movement, over and over, with not enough rest. Think: lots of jumping, sprinting, cutting, or hills.
- Acute injury = one clear moment. A twist, pop, fall, or collision.
According to Boston Children’s Hospital’s guidance on knee pain in children, most youth knee pain is not dangerous, but you do want to watch for red flags (we’ll cover those).
Why “growth plates” matter
A growth plate is a softer area near the end of a child’s bone where growth happens. It’s more vulnerable than adult bone. That’s why kids often get pain where tendons attach near growth plates—like in osgood schlatter at the top of the shin.

Knee pain young athlete: Osgood-Schlatter explained (with examples)
Osgood Schlatter is one of the most common causes of knee pain in active kids, especially in sports with running and jumping (soccer, basketball, volleyball, football, track).
What it feels like
- Pain right below the kneecap on the bony bump at the top of the shin (tibia)
- Worse with:
- running
- jumping
- hard cuts
- kneeling
- Often better with rest, then flares again when activity ramps up
Many kids also get a visible or tender “bump” there. That bump can stick around even after pain improves.
What’s actually happening (in plain words)
The big thigh muscle (quadriceps) pulls on a tendon that attaches near a growth area on the shin. During a growth spurt plus heavy training, that spot gets irritated. It’s not usually a “tear.” It’s more like the body saying, “Too much pulling, too often.”
Real-life example with numbers
Let’s say your 13-year-old plays travel soccer:
- Team training: 2 practices/week (90 minutes each) = 3 hours
- Games: 2 games/week (60 minutes each) = 2 hours
- Plus “extra touches” in the driveway: 30 minutes, 3 days/week = 1.5 hours
That’s 6.5 hours/week of mostly running and cutting.
Now add a tournament weekend:
- 3 games Saturday + 2 Sunday = 5 games
- If each game is 60 minutes, that’s 5 hours, plus warm-ups.
That one weekend can double their weekly load. Osgood Schlatter often flares right after that kind of jump.
What helps most (usually)
- Reduce pain triggers for 1–3 weeks (not always total rest)
- Ice after activity for 10–15 minutes
- Quad and hip strength work (simple, controlled)
- Temporary support like a patellar tendon strap (some kids love it, some don’t)
And yes—kids can often keep playing some while it calms down. The goal is to keep pain in a safe range, not “win the pain contest.”

Other common causes: patellofemoral pain + Sever’s disease
Not all knee pain is Osgood Schlatter. Two other big ones show up a lot in youth sports.
Patellofemoral pain (front-of-knee pain)
This is often called “runner’s knee,” but kids in court sports get it too. The pain is usually:
- around or behind the kneecap
- worse with stairs, squats, running, or sitting a long time (“movie theater sign”)
The Mayo Clinic explains patellofemoral pain syndrome as pain from the kneecap area, often linked to overload, mechanics, or muscle imbalance (like weak hips or tight quads/hamstrings) (Mayo Clinic).
Parent tip: If your kid says, “It hurts around the kneecap,” think patellofemoral pain. If they say, “It hurts on the bump below the kneecap,” think osgood schlatter.
Sever’s disease (heel pain that can change how the knee feels)
Sever’s disease is heel pain from irritation at the heel growth area. It’s common in ages 8–13, especially in soccer, basketball, and lacrosse.
So why include it in an article about knees? Because kids with heel pain often start running funny (limping or toe-walking). That can shift stress up the chain and trigger knee pain.
Signs of Sever’s:
- pain at the back/bottom of the heel
- worse after running
- better with rest
- often shows up during growth spurts
A simple heel cup insert and load reduction can make a big difference. Also: check shoes. Worn-out cleats plus hard fields can be a perfect storm.
When it’s “normal growth” vs. an injury
“Growing pains knee sports” is a phrase parents use a lot. Some soreness with growth and training is normal. But pain that changes how they move is a sign to adjust.
More likely “normal-ish”:
- mild soreness after a hard week
- pain that improves with a rest day
- no limp, no swelling
More likely needs evaluation:
- swelling, locking, giving way
- pain that wakes them at night
- major limp or can’t fully bend/straighten the knee
If you’re unsure, our common youth sports injuries: parent warning signs can help you sort it out.
Practical examples (by age, sport, and schedule)
Here are a few real scenarios I see all the time.
Example 1: 10-year-old basketball player with heel pain and knee ache
- Age: 10
- Sport: basketball (2 practices + weekend game)
- Complaint: heel pain after practice, then “knee feels weird” on stairs
What’s likely:
- Primary issue could be Sever’s disease in the heel.
- The knee ache may be from limping and landing differently.
What to try for 2 weeks:
- Cut jumping volume by 30–40% (less full-court scrimmage, more skill work)
- Add heel cups ($10–$20)
- Ice heel after practice 10 minutes
- Pain rule: if pain is over 3/10 during play, back off
Example 2: 12-year-old travel soccer player with bump pain (classic osgood schlatter)
- Age: 12
- Plays: 3 practices/week + 1 game, plus weekend tournaments twice/month
- Pain: point tenderness on shin bump, worse after sprints
What’s likely:
- Osgood Schlatter, especially if they recently grew 1–2 inches.
Simple load math (this helps parents a lot):
- Normal week: 3 practices (1.5 hr) = 4.5 hr + game 1 hr = 5.5 hr
- Tournament week adds 4 games (4 hr) = 9.5 hr total
- That’s a 73% jump in weekly load (from 5.5 to 9.5)
Big jumps like that often trigger flare-ups.
Plan:
- Keep them playing, but reduce sprinting/jumping for 10–14 days
- Add strength 2x/week:
- wall sit: 3 sets of 20–30 seconds
- glute bridge: 3x10
- side steps with band: 2x10 each way
- Ice after sessions
- Consider a patellar tendon strap for games
Example 3: 15-year-old runner with kneecap pain (patellofemoral)
- Age: 15
- Running: went from 10 miles/week to 18 miles/week in 2 weeks
- Pain: around kneecap, worse on hills and stairs
What’s likely:
- Patellofemoral pain from a fast training increase and stress on the kneecap area.
Simple fix:
- Drop to 12–14 miles/week for 2 weeks (not zero)
- Avoid hills temporarily
- Add hip strength 3x/week:
- clamshells: 2x12
- single-leg deadlift (bodyweight): 2x8 each leg
- Check shoes if they have 300–500 miles on them (many do!)

Common mistakes and misconceptions
A few things trip parents up again and again:
-
“It’s just growing pains, so ignore it.”
Some pain is common. But pain that causes a limp is a signal to change something. -
“Rest until it’s gone, then go right back to full speed.”
That usually causes a flare-up. You want a gradual ramp back. -
“More stretching will fix it.”
Stretching can help, but strength and load management usually matter more. -
“If there’s no swelling, it’s not serious.”
Overuse problems can be very painful without big swelling. -
“They need to play through it for recruiting.”
College coaches want healthy athletes. Missing 2–3 weeks now can prevent missing 2–3 months later. If you’re worried about the bigger picture, our return to play after injury guide is worth reading.
Step-by-step: What to do this week (parent game plan)
Here’s a simple plan you can start today.
Step 1: Do a quick pain check
Ask:
- Where does it hurt? (point with one finger)
- What makes it worse? (stairs, sprinting, jumping, sitting)
- Rate it 0–10.
Rule of thumb: keep sport pain at 0–3/10. If it’s 4+, modify.
Step 2: Look for red flags (get checked soon)
Call a sports med provider if you see:
- swelling that’s new or growing
- knee “giving way,” locking, or catching
- can’t fully bend or straighten
- pain after a clear twist/fall
- fever, redness, or pain at night
Step 3: Reduce the “spikes” for 7–14 days
Don’t just cancel everything. Instead, cut the biggest triggers:
- Less jumping/sprinting
- Fewer full-speed cuts
- Shorter practices (example: 90 minutes → 60 minutes)
Step 4: Add two strength sessions per week (15–20 minutes)
Pick 4 moves:
- wall sit (quads)
- glute bridge (hips)
- step-down from a 4–6 inch step (control)
- calf raises (great for Sever’s and overall leg support)
Step 5: Plan the return ramp (simple math)
If they were doing 6 hours/week before pain:
- Week 1: 4 hours
- Week 2: 5 hours
- Week 3: 6 hours
Slow is fast when you’re trying to stay on the field.
Key takeaways / Bottom line
Most knee pain young athlete issues come from overload during growth—especially osgood schlatter, patellofemoral pain, and even heel pain like Sever’s disease that changes how kids move. The win is not “toughing it out.” The win is smart changes: reduce workload spikes, keep pain in a safe range, and build simple leg and hip strength.
Use the one-finger pain location test, watch for red flags, and adjust training for 1–3 weeks. If symptoms don’t improve, or you see swelling/locking/giving way, get a sports med check. You’re not overreacting—you’re being a good sports parent.
