Is Jumping On A Trampoline Bad For Your Knees?

The trampoline provides an excellent way for many people to spend their leisure time. Additionally, it offers an opportunity for collective enjoyment with your family and friends.

However, more recently, many people have raised concerns about the safety of the trampoline.

Specifically, the situation surrounds the possible damage to the physical health of the jumper.

One such question is regarding the potential adverse effect of the trampoline on the jumper’s knees.

Can jumping on a trampoline be bad for your knees? A trampoline may cause damage to your knees in some cases. The reasons for such damage are diverse, ranging from lack of proper trampoline safety equipment to a misguided landing.

However, many of these aspects can be easily prevented by the jumper through appropriate care. Keep reading the article to determine how trampoline may affect your knees and the different strategies you may use to reduce the adverse effects.

How can trampoline jumping cause damage to your knees?

A significant reason that trampoline ends up damaging most jumpers’ knees is the lack of concern shown by the jumpers for such possible damage.

Mostly, we consider jumping on a bouncy surface, with no apparent risks, to be perfectly safe for our knees. However, flipping and jumping on the trampoline can be a contributor to knee damage.

Here are some of how your knees may get adversely affected by jumping on a trampoline.

Trampoline Absorption Myth

One common myth about trampolines is that the bouncy surface and the spring action absorb all the jump’s shock. Thus, there is no pressure exerted on your knees.

However, the truth is that most trampoline surfaces only absorb part of the shock from the jump. It exerts the rest of the shock on your knees, causing them to sustain redundant damage.

It may cause your kneecap to dislocate or your knee joint to wear off in the long run.

Performing Stunts

Performing stunts without proper protection and guidance can end up hyperextending your knees. In this case, you may feel excessive pain in the knee area.

In difficult situations, such hyperextension can break the soft ligaments present inside the knee—this aspect results in reduced knee function and constant difficulty moving.

Pre-existing Knee Issues

People with subtle knee problems may end up aggravating their knee damage by jumping on a trampoline.

In most cases, the knee damage increases due to the constant pressure sustained by your knee joint during the jump.

Unnecessary Impact

Jumping from the trampoline to the ground directly may break your knee joint. Our body becomes used to the motion of the regular jumps when we are jumping on a trampoline.

However, when we land directly on the ground, it cannot maintain the flexibility of the joint during normal walking routines.

Consequently, it may dislocate your knee cap immediately.

Trampoline Collisions

Sometimes, banging into another person or surface around the trampoline may crush your knee joint completely.

This is precisely the case if you are jumping too high and at incredible speeds. In such cases, you may require surgery to move properly.

Additionally, many repetitive stress injuries to your knee may result from constant trampoline jumping. Although jumping once in a while may not cause a significant problem, performing regular trampoline stunts may be dangerous.

More importantly, a stunt performed without precision may result in landing in an awkward position. In this case, you may have to take a complete bed rest before you can walk without difficulty.

A significant injury attached to trampoline jumping is called the Jumper’s knee condition, which stands as one of the most frequently occurring tendinopathies in the United States.

It occurs in as high as 20 percent of the regular trampoline jumping. Additionally, the condition affects both male and female jumpers equally in the case of bilateral tendinopathy.

On the other hand, unilateral or one-sided tendinopathy affects more male jumpers than female jumpers. This disease is the remnant of a repetitive strain injury.

Additionally, it can also occur in kids who regularly practice trampoline jumping.

How to avoid knee injury from trampoline jumping?

Knee injury from trampoline jumping may be difficult to avoid completely. After all, your knees do get the strain from each jump.

However, it is possible to reduce the damage sustained by your knees during trampoline jumping significantly using the following methods:

  1. Instead of using a traditional, hard-surfaced trampoline, you may opt for a mini-trampoline. The major benefit of this trampoline is the reduced stress on your knees from each jump. At the same time, they help strengthen the knee muscles, allowing them to sustain the damage. Such trampolines once used to be specialist products used by physiologists to help their patients. However, anyone can buy them today from sport-stores.
  2. Never jump off the trampoline to the ground directly. Remember, your body needs to get back into position before hitting the hard surface. Instead, slow down on the trampoline and then walk off onto the ground.
  3. Wear safety equipment when jumping on the trampoline. Knee gear helps to avoid most damage or hyperextension issues.
  4. Consult your physiologist and orthopedic consultant if you experience severe pain after jumping on the trampoline.
  5. Avoid jumping on the trampoline regularly. Jumping once in a while has minimal adverse effects on your knees. However, jumping regularly may aggravate the damage.
  6. Always jump on the trampoline alone and at a proper distance from other people. Do not jump on the trampoline with another person. A serious collision may dislocate your knee completely.
  7. Use your trampoline on level ground and inspect it for any spring damage. Jumping on your trampoline on an uneven surface maximizes the damage to your knees.

Additionally, try buying better quality trampolines with better spring work and surface quality. This way, the damage your knees retain from trampoline jumps will be minimalized.
How Trampolines Can Help STRENGTHEN Knees


Your knees need protection to stay healthy in the long run. Make sure you protect them while using a trampoline.

If you’re an avid trampoline user then it may be worth adding in extra exercises to strengthen your knees and the areas around them to help them become more resilient to injury.

If you’re already dealing with knee issues, trampolines can help improve their condition, but only when done in a controlled and monitored manner, preferably with a professional.
