    Hello! How long does the swelling normally last. with a hyperextended knee? Also, how can you tell it’s more serious then what the Dr.said without a MRI

    • Rochandrs says:

      I got hurt at work and they refuse to give me a MRI. He said if I’m still having problems with it in 4 to 6 weeks. I can get one. It been 15 days.

      Hi I recently hyperextended my right knee a few weeks ago. My swelling lasted about a week, and then it would come back after every soccer game I played. If it’s quite obvious that you hyperextended your knee, they won’t need an MRI. I was walking on mine the same week I hurt it. Though I am just now starting PT for it because I’m also going through ACL/Meniscus rehab. Mild hyperextension does hurt and swell quite a bit, but it’s not that noticeable whenever you fully extend your knee (when I had this, I thought I had bruised all of the soft tissue in my knee). Severe hyperextension, however, is quite noticeable and is in the double digits of negative degrees (I can go -9 degrees in mine right now, which isn’t too bad). If the swelling doesn’t go down at least enough to be obvious, it’s serious and you may have injured other things in your knee as well. If it’s just a little sore, and the swelling goes down a lot within the first week, it’s just mild, and I recommend that you do the exercises/stretches this website has provided. Hope this helped 🙂

    • Hello,

      A hyperextended knee can last anywhere from a few days to a few weeks. It depends on the extent of your injury. If your knee continues to swell or feel painful after a number of weeks, it may be time to consult your doctor to look into an MRI.

    I just had my first PT appointment for ACL/Meniscus rehab on my left knee. It turns out I previously hyperextended my right one. So now, I’m dealing with 3 injuries. Any tips on how to manage all 3, if I’m stuck on crutches for 2 more weeks?

      Hello,

      sorry for the late reply, how are your knees now? The simplest and best advice I can give is to continue to use cold therapy, stretch, eat healthy and drink plenty of water.

  3. Generally speaking strengthening the medalias of the quads is the quickest way to recover from injuries to the knee that effect stability. If hyper extension was a cause of the injury and the swelling has subsided during daily life you could begin performing hip extension through a flex knee for hamstring stability recruiment and depending on the health of the meniscus can begin single leg dynamic stability exercises for the ankle, knee, and hip. Such as single leg cross reach, anterior reach, etc…

    It’s easy to forget about the glut which will only prove to be detrimental in the future as being quad dominate will only stress the anterior knee more so. A split squat or lunge should be performed by all those capable especially athletes 1-2 weekly minimally with the body weight.

    Hi, I hyperextended my knee about a month ago. My doctor checked it out, It was a mild injury. I’ve taken all the steps to heal even with the antiflammatory pills. About 4 weeks have gone by and just today I went for a light jog on the road and there was still a slight pain on the inside of my knee. What do you suggest at this point? Keep resting? Exercises to regain strength? Thank you so much for your time.

    Hello I have a very mild hyperextended knee that I got this Sunday it’s getting better and there was also almost no swelling. I’ve been putting icy hot on it, been taking ibuprofen, stretching it, and overall taking care of it. Although I’m taking care of it I have a timed mile and other speed sills for soccer on Thursday. Would it be safe to participate in them?

    it just happen to me and i think that mine is only miner but i can not walk on it or stand on it without a stick or a cane of some sort

  7. Amanda says:

    Hi I recently hyperextended my right knee is there any helpful tips? I have done the RICE method and I have done plenty of stretches. But after it happened I keep dancing and then the next day I ran 2 miles and then went to a 2 hour soccer practice. Should I just take a break from everything? Thanks for your time.

    • egrabin says:

      Hi Amanda,

      If your knee doesn’t hurt and have any swelling, then you should be good to go. Listen to your body, if it’s painful, has swelling or is hard to bend, then you should take a break.

    I am trying to figure out what I did to injure my leg. I have most of the symptoms of a hyperextension injury. I am a 67 year old male and I train 3-4 hours daily. This would include cycling approx. 2-3 hours a day, daily gym training with free weights and cardio such as treadmill. Plus as much surfing as I can. The injury occurred after a training arise on my road bike and then followed by work on the treadmill. I was only ion my second mile of running at a slow pace when my left leg just collapsed. I slowed the treadmill down thinking i could walk the pain off but I could not. I went home and began icing for 20 minute every few hours and also using the foam roller to try to move blood though the injured areas. Today is my 9th day with no results. It hurts on the inner part of my leg above the calf next to the knee and the back of my leg in the crease of the leg behind the knee. I can barely bend my leg and there is very little range of motion. I hobble around kind of like I have a peg leg. The knee itself isn’t really sore. I cannot get an appointment with my orthopedic doctor for 2 more weeks. I was wondering if you had any suggestions on what the problem is and what else I can do to perhaps heal it on my own. I thank you in advance for any suggestions you might have to offer me.

      Hello Jack,

      I want to state first that I have no certified credentials to diagnose your injury, but can only give my opinion. Based on the location of your injury and how you stated when you noticed it, my guess would be that you may have done something with your meniscus. Do you have any sharp pain?

    About 3 weeks ago Ihyperextended my right knee…. The doctor has seen me more than once for an appointment for my knee.. They haven’t given me an MRI yet but so far they think I tore my acl does anyone know if I could be Almost 90% sure I didn’t tear it

  10. Yusef Garrett Davis says:

    Hi I’ve been dealing with a weird injury and I can’t really tell if it’s a hyper extension or not. My right leg on the inside has extreme tightness and when I try to walk normal it doesn’t bend back like a leg usually would so I kinda have a small limp. I had been running track and have been sitting down off of it for 3 weeks and I can’t figure out why it won’t go away. I’ve been stretching and icing for a while now too.

    • egrabin says:

      Hello Yusef,

      Are you saying that you’re unable to fully straighten your knee or full bend it back(ankle hitting your butt)? Is your knee swollen? Does it have any sharp pain?
