LCL Sprains and Tears - Symptoms, Tests, Recovery Times. Plus: Do I Need Surgery for my LCL Injury?

Published 2024-01-23
A lateral collateral ligament (LCL) tear is a knee injury that seldom happens in isolation. The force that causes it is usually so big that something else also gets injured. Sports physio Maryke Louw explains how the LCL typically gets injured, what the symptoms are, how the injury is diagnosed and graded, what the treatment options are, and what the recovery times might be under various circumstances.

    I'm 70 and suffered an LCL sprain last year. The previous week (I think), I had a sharp pain in the outer side of my hamstring while doing sled pulls. I may have been taking too long a step or moving too quickly. The pain passed quickly but the following week, the LCL suddenly went. My GP had just retired so I went to Urgent Care. The X-Ray result: "No fracture or dislocation is identified. Minimal degenerative changes of the medial compartment. No significant joint effusion. The soft tissue is unremarkable." The nurse even said I was unusually free of arthritis for a man my age. I was prescribed physical therapy and continue to do rehab exercises since being released. Mostly, I have full use but occasionally, the knee gets a bit of slop and there is a bit of pain. I reset the knee by sitting on my haunches with my hand inserted at the back of the knee (this was not prescribed, just something I picked up over the years). Anyway, I weightlift 3 times a week. Am I pushing my luck, especially with squats and deadlifts? I have an excellent trainer who watches me like a hawk.

    Hi Maryke.. thanks a lot for this content and your channel. I've been waiting for the LCL video and I'm glad and grateful you finally made it!. Had a snap sound while doing yoga a month ago, no inflammation nor a lot of pain, small discomfort continued till now and when saw the orthopedist and MRI, there's a partial tear. I didn't wear the brace as didn't really think was serious before the MRI 😢, hope still recovers well, I'm a long distance runner and I've been tormented with the idea of not being able to run anymore..
  • @ladyvader3173
    I just got LCL augmentation surgery on an acute tear + ACL reconstruction 8 days ago. Can't wait for the exercise video, your content has helped me tremendeously with my (according to my ortho) hopeless and chronic achilles tendinopathy :)))
  • @The_Bladdenbolo
    I just injured my LCL this past saturday at a jiu jitsu tournament and this video gave me a ton of peace of mind that my injury isnt extreme and wont need surgery
  • Thank you Just realized I might need surgery Reoccurring lcl injury from basketball 😢
  • @ianreynolds2208
    I have a grade 2 from running about 10 years ago now. I took a few years off running, came back was doing great and then re injured it again. Took a few years off. Can’t really run past three miles without it bothering me :( I May need surgery. Thanks for the information. Well done!!
  • @brendacurrie358
    Brilliant overview . Does it take a few days to determine the extent of these injuries and what else is involved ?
  • @fredt3727
    Basically what I found through trial and error is, if you have no ACL left or a dysfunctional ACL (because it is not fully healed), then you are at a higher risk of "just" injuring the LCL again and again and again.... 3 times so far for me, full-ish recovery is about 2-3 weeks after each "injury event". This is all after a full ACL tear 2 years ago (which i "rehabed" without surgery). I am in my 40s.

    I’ve had a right knee injury for over 5 years. It hasn’t bothered me much through the years. That’s why I didn’t do anything about it. But in the last 3 months it has been getting worse. There is a lot of inwards movement on my knee and the outside of my knee is very tender when I press on it. When I squat my knee usually pops out and goes back in when I stretch it out. I can’t sit down on the ground and cross my legs because my knee would pop out. I can run in a straight direction but find it impossible to change directions without my knee popping out. I’m quite sure my LCL is the problem here and possibly some other ligaments as well.

  • @nhatvulong9782
    hello. very nice and educated video. Thank you Doctor. I have been through very serious ACL knee injury on right knee and I have surgery on that and have been playing football for 2 years. And recently I have another injury on the left knee while playing football. While put the left feet on the ground, the other player push me from the inside to outside and I heard a small crack (not big as the crack I have at the ACL injury, and my knee rotated like my ) and I feel that crack is not the crack of ACL torn (Grade 3). After that my outside knee is swollen and hurt, the inside knee seems not very much. After 3 weeks I am now able to walk upstair but still a little uncomfort to walk downstair. I still feel the knee stable unlike the ACL injury I had before for the right knee so I think the ACL still there, maybe stretched but not completely torn. My question is : - Do I had an LCL tear or MCL tear or both if I only swelling much from outside of the knee? - Should I rest and return to sport longer than usual to help my knee perform better and my knee health overall for long time after?
  • @thetyler8738
    I currently have in-between a grade 2/3 lcl tear. I'm using a brace for 6 weeks then getting it reevaluated for surgery. I've always been going to PT twice a week. I'm able to walk, pain level has dropped significantly and I'm starting to get near the 90 degrees bend mark. But the problem is sometimes my knee gives out. I have 2 weeks til I get reevaluated hopefully I don't need surgery, I have track field that starts in a few weeks. Do you think I'll be back by then?

    Yesterday I had a very loud audible POP while at Jiu Jitsu early in the morning and I had some minor pain on the outside of the knee. I was able to go though the rest of the day without issue. By the end of the day it was starting to get sore. I iced it last night and plan to ice today a few times as well. Overall, I think it is pretty minor. My bigger question is what causes the POP? People on the other side of my gym heard the POP. Thank you for your time.
