Jumper’s knee is an overuse injury of the patellar tendon, the thick band just below your kneecap, and volleyball produces more cases than almost any other sport. If your knee aches after practice or stings on every landing, it responds well to the right plan. This guide covers symptoms, whether you can keep playing, and how to fix it. For hands-on help, our team offers sports physical therapy for knee pain in Cherry Hill.
What Is Jumper’s Knee and Why Do Volleyball Players Get It?
Jumper’s knee, also called patellar tendinopathy or patellar tendonitis, is irritation and gradual breakdown of the patellar tendon caused by repeated jumping and landing. The tendon connects your kneecap (patella) to your shinbone (tibia) and works like a spring every time you take off or land.
Volleyball loads that spring constantly. A study of elite athletes by Lian and colleagues found jumper’s knee in about 45 percent of elite volleyball players, the highest rate of any sport studied. Norwegian research also describes a “jumper’s knee paradox”: the highest jumpers are the most likely to develop it. As a tendon overload problem, it responds best to targeted tendinopathy treatment.
How Jumper’s Knee Occurs in Volleyball
Jumper’s knee builds up slowly when the load on the tendon outpaces its ability to recover. Common triggers include:
- The plant leg on approach jumps for spiking
- Repeated block landings at the net
- Low defensive squats that keep the knee deeply bent
- Hard indoor courts that return more force to the leg
- Sudden jumps in volume, such as tryouts, tournament weekends, or school and club seasons back to back
Jumper’s Knee Symptoms and Stages
The main symptom is pain right below the kneecap, at its lower tip. You may also notice:
- Pain when jumping, landing or squatting
- Pain when going down stairs or after sitting for a long time
- Stiffness first thing in the morning or at the start of practice
- Tenderness when you press on the tendon
- Pain that eases once you warm up, then returns after play
Clinicians often grade jumper’s knee in four stages:
| Stage | What You Feel | What It Means for Volleyball |
| 1 | Pain only after play | Keep playing and start a strength plan |
| 2 | Pain at the start and after play that eases during warm-up | Play with reduced jump volume and a structured rehab plan |
| 3 | Pain during play that affects performance | Step back from full practice and get assessed |
| 4 | Sudden sharp pain, a pop, or trouble straightening the knee | Stop playing and see a doctor right away, as the tendon may be torn |
Is It Jumper’s Knee or Something Else?
Several volleyball knee problems feel similar. Patellofemoral pain sits around or behind the kneecap rather than below it. Teen players may have Osgood-Schlatter disease, which causes a painful bump on the shin below the knee, or Sinding-Larsen-Johansson syndrome, which irritates the growth area at the bottom of the kneecap. Knee injuries from diving in volleyball, such as bruising and prepatellar bursitis, cause swelling on the front of the kneecap after hitting the floor. Our guide to common knee injuries in athletes explains the differences.
Can You Play Through Jumper’s Knee?
Often, yes, in the early stages. Complete rest weakens the tendon, so most players do better by staying active with a lower load. Use this simple pain rule:
- Pain during play stays at about 3 out of 10 or lower
- Pain settles within 24 hours
- Pain is no worse the next morning
If all three are true, you can usually keep playing while you rehab. Cut jump volume first: skip extra hitting lines, limit jump-based conditioning, and rotate out of drills with repeated blocking.
Stop and get checked if you notice sharp pain, swelling, pain at rest or at night, pain that gets worse week to week, or a pop. Playing through those signs can turn a few weeks of rehab into several months.
How to Fix Knee Pain From Volleyball: A Phased Jumper’s Knee Treatment Plan
Ice and rest ease a flare but do not repair the tendon. Tendons strengthen only with progressive loading, so the most effective jumper’s knee treatment follows three phases.
Phase 1: Calm the Tendon Without Shutting Down
Reduce jumping and deep squatting to a level that meets the pain rule. Then add isometric holds, which can ease tendon pain. Try a wall sit or a Spanish squat, where you sit back against a strap anchored in front of your knees. Do 5 holds of 30 to 45 seconds, once or twice a day.
Phase 2: Rebuild Tendon Strength
Once pain settles, move to heavy slow resistance training: leg press, split squats and decline squats, each done with about 3 seconds down and 3 seconds up, 3 times a week. Research supports roughly 12 weeks of this work for lasting results. When heavy loading still hurts, blood flow restriction training lets you build strength with much lighter weights.
Phase 3: Return to Jumping and Game Play
Reintroduce jumping in steps: pogo hops, then box jumps, then two-foot jumps, then full approach jumps. Next come practice drills, partial matches and finally full games. Move to the next step only when the previous one meets the pain rule.
Clinic Treatments That Speed Things Up
A sports physical therapist can add manual therapy, dry needling and shockwave therapy for stubborn tendon pain, which has research support for patellar tendinopathy that does not respond to exercise alone. Injections and surgery are rarely needed and are saved for cases that do not improve after months of quality rehab.
Landing Fixes That Take Pressure Off Your Patellar Tendon
How you land matters as much as how often. Focus on these fixes:
- Land through your hips. Push your hips back so your glutes absorb force instead of only your quads.
- Keep your knees over your toes, and do not let them cave inward.
- Land softly and quietly, because loud landings usually mean stiff knees.
- Land on two feet after blocks when you can, so both legs share the load.
- Improve ankle mobility, since stiff ankles push more force into the knee.
- Check side-to-side balance, because many players load one leg far more than the other.
At Rehabletics, force plate testing measures how much force each leg absorbs, so we can spot imbalances before they turn into pain.
Jumper’s Knee Prevention Exercises for Volleyball Players
To prevent jumper’s knee, track your jump volume, raise training load gradually, warm up before every session, and wear supportive court shoes. Then build a stronger tendon with 2 to 3 strength sessions a week:
- Spanish squats or wall sits for tendon tolerance
- Single-leg decline squats for patellar tendon strength
- Bulgarian split squats for single-leg control
- Single-leg Romanian deadlifts for glute and hamstring strength
- Calf raises for ankle strength and better landing absorption
Finish with drop landings and stick-the-landing jumps. For more strength ideas, see our knee strengthening exercises.
Does a Jumper’s Knee Brace Help?
A brace can make play more comfortable, but it does not heal the tendon.
| Option | What It Does | Best Use |
| Patellar tendon strap | Changes how force passes through the tendon and may lower pain | Practice and games |
| Knee sleeve | Adds warmth and compression | Morning stiffness and comfort |
| Kinesiology tape | Provides short-term pain relief | Tournament days |
| Knee pads | Protect the kneecap from floor contact | Diving and digging |
Our clinicians also use kinesiology taping alongside a strengthening plan.
When Should a Volleyball Player See a Sports Physical Therapist?
See a sports physical therapist if pain lasts longer than 2 to 3 weeks, changes how you jump, returns every season, or comes with any red flag listed above. In New Jersey, you can see a physical therapist directly without a referral, so treatment can start sooner.
