Badminton Jumpers Knee

Since I play so damn much, and since I am no longer a spring chicken, I have to deal with aging joints, tendons and muscles. Hopefully with proper warmup, strength training and footwear I can avoid sudden injuries (like an Achilles tear) but there seems to be no way to totally avoid smaller problems.

So what’s on my plate of maladies today? Jumper knee.

Jumpers knee, technically knows as patellar tendonitis, is when the tendon gets inflammed due to overuse and you feel pain the the front of your knee. As the name suggests it happens in sports where jumping is involved like basketball, volleyball and badminton (though of course all the articles about it on regular sports sites never mentions badminton. Sigh…just more of the world against badminton.) My non-racket knee is the one that bothers me, which kinda makes sense. My right thigh (racket thigh) is built like a brick shithouse, but my non-dominant side is lagging.

While I’ve basically wished on a star to fix my tennis elbow (a surprisingly useful tactic), I know enough people who had knee surgery to know that knee pain isn’t that easy. There is no threshold like with tennis elbow, and if it’s not taken care of properly, it can lead to surgery or even an inability to walk properly. Yikes

So I did what any good player does and bought a new brace. This is really the quick and easy fix because once I use it there is no pain at all. The brace puts pressure on the weak part of the tendon and makes everything work much smoother.

The miracle fix?

No pain, no problem, right?

Well, not exactly. Wearing a brace is equal to taking an asprin. It might mask the pain for a bit, but you’re not actually solving the problem. So it’s up to body work to fix the problem.

A strain in the patella tendon means something along the chain isn’t working right and the knee has to pick up the slack. It could be a hip thing, it could be an ankle thing, it could be a lower back thing. Something is too tight, or not working right, and disrupting the chain. The big huge butt muscles should be taking the strain, not the weak little knee tendon, so somehow I’m not moving my body right. Too much strain is on the knee.

My first line of defense is foam rolling. To help the tendon smooth and stretch, I’ve been laying down on a foam roller and stretching away my upper thigh. I try to do this a few times a day, once before and once after badminton.

Then comes the stretching, which seems the best way to tackle this problem. My favorite stretch, and one I try to do several times, is the quadriceps stretch where you kick your leg back to touch your butt and you hold it there for awhile. I am also trying to do stretches to open my hips up more and doing some calf muscle stretches. Basically with my stretches I am not only trying to strengthen the knee, but stretching and activate any muscles that are supposed to be working harder. (For a few websites with good stretch suggestions check out here and here.)

Just like with tennis elbow I realize my off-court life plays a big part. Actually, I sometimes forget to put on my knee brace and only when I’m packing up to go home do I realize I didn’t have it. Playing doesn’t seem to hurt it a lot. It hurts more when I have been sitting down and long time, then stand up. Or, when I’m sitting in my favorite position: extreme cross-leg.

Every since I was a kid I have favored a really extreme cross-leg pose that is more “yoga” than “normal person sitting.” I’ve trained myself out of doing it in front of people since I got teased mercilessly in high school for it, but when I’m at home, with no conscious thought on my part, I find my legs twisted around me. These days, after awhile, my knee hurts.

Not the arms, but this is how I sit with my legs when I’m at the computer writing. For whatever reason this feels most natural to me. 

So I’m trying to wean myself off it, and sit with my legs resting normally on the ground like an adult. It’s hard to change this habit though.

So we’ll see what happens as time goes on. Fingers crossed I caught it soon enough, and mild enough, that these small actions will fix it quickly. Of course the other course of treatment is resting and taking several weeks off, but if I can still walk, then I’m still playing so that’s not a viable option for me.

Have you dealt with jumper’s knee? Have any suggestions for me? Let me know in the comments below!

    I too have the same issue on my dominant knee. The physiotherapist rightly diagnosed it to be a hip muscle issue and strain on the knee. My exercises where to Side Step with a elastic band (e.g. Theraband) around the knees NOT ankles and moving 20 to 30 feet each direction. It has helped a lot.

    Best of luck on your recovery.

      That’s interesting. Is that the only exercise the doctor suggested? Are you recovered now or still having some pain?

      1. Carlos Nazareth

        No multiple exercises
        01) Standing Quadriceps Stretch (3 Reps, hold 20 sec, 2-3 per day)
        02) Standing Hip Flexor Stretch (3 Reps, 20 sec hold, 2-3 per day)
        03) Clamshell with Theraband (15 reps, 2 sets)
        04) Hip Abduction Straight Leg Raise (15 reps, 2 sets)
        05) Side Stepping with Theraband (2-30 ft, 2 sets)
        06) Knee Single Leg Squat (Sets: 2, Repetitions: 10, Sessions per day: 4 X week)
        07) Vertical Jumps (Sets: 2,Repetitions: 10,Sessions per day: 4 X week)
        08) Lateral Bounding (Sets: 2, Repetitions: 10, Sessions per day: 4 X week)

        Yes they helped a lot. But I did slack off when doing these routines.

          Thanks for that. It’s good to hear what actual experts have recommended and not just Dr. Internet.

    Hi Becky,

    I came across your blog while searching for badminton to. Jumpers knee. How long did yours take to heal?


    1. Becky (Post author)

      To be honest it isn’t 100% even now. But it just gives me a twinge of pain every now and then and I stopped wearing a brace. I think I wore the brace for about 2 months total and I stopped foam rolling that tendon though I do do specific knee stretching after every session so I think that has helped it a lot. How long have you had your problem?

    I’ve had extreme tendonitis in both knees so much so that I had to have 2 surgical proceedures to repair them.

    Strengthening the quads through the years of just aching helped me to continue playing(6 days per week). The 2 surgical proceedures really helped big time 🙂 Totally recovery from there 🙂

    Nowadays I still play at least 8-10 hours per week but I have to avoid hard floor courts, I only play on sprung floors, they really are soft on your knees.

    Hard floors will get you in the end 🙁 keep your weight as low as possible, you’re young enough that your joints will last for a long time yet especially if you land correctly from any jumping.

    good luck with them:)
