If my knee pops and cracks, could this mean I have an MCL tear?

If my knee pops and cracks, could this mean I have an MCL tear?

No: There can be many causes for pops and crackles (called "crepitus"), including torn meniscus, patella chondromalacia, loose body, knee swelling following an injury, or synovitis (inflammation of the lining). Some times normal knee pop and crack. Mcl tears are associated with pain, tenderness, and swelling along the medial joint line and a tendency for the knee to want to buckle with activity. ...Read more

Mcl (Definition)

The medial collateral ligament (MCL) is a wide band of tissue (a ligament) that runs along the inner side of each knee, connecting the thighbone (femur) to the shinbone (tibia), to help stabilize the knee joint. The MCL's main purpose is to prevent knees from bending too far ...Read more

The sides of my knee hurt the moment I stand and feel like a brace being pushed into the sides. Knee also sometimes cracks/pops when walking. MCL/LCL?

The sides of my knee hurt the moment I stand and feel like a brace being pushed into the sides. Knee also sometimes cracks/pops when walking. MCL/LCL?

Possibly: You are right in saying that the medial and lateral collateral ligaments run on the inside and outside of the knee and they can cause pain. But usually this would only occur if you had injured them and it is fairly uncommon to injure both. If you are having trouble, consider being seen where an exam and possibly an MRI can pinpoint the problem. ...Read more

I had a fall and my knee popped as i fell. I can't walk or fully extend my leg. Id this an MCL tear? Pain on the inside of my knee.

I had a fall and my knee popped as i fell. I can't walk or fully extend my leg. Id this an MCL tear? Pain on the inside of my knee.

More likely ACL Tear: Injury of the knee associated with a "pop" at the time of injury is most often associated with an injury to the anterior cruciate ligament. This injury is often associated with concurrent injuries to the menisci, which could explain the pain on the inside (medial) side of the knee. Bone bruising and injuries to to articular cartilage may also occur. I strongly recommend an orthopedic evaluation. ...Read more

Is it normal for my knee to be tingling after an MCL tear reconstruction?

Is it normal for my knee to be tingling after an MCL tear reconstruction?

it can be: It depends on what was done and how long you are following surgery. If you are in first few weeks following surgery it could related to a number of things, all likely to resolve with time and healing. If it is late, it could represent sensory nerve entrapment and might need to be evaluated. ...Read more

Need XR: You may have dislodged the plastic piece between the femoral and tibial component. Dislocation of the polyethylene bearing is more common in a mobile bearing knee replacement. You should go in and get an x-ray. If you had full range of motion prior to your injury, you should be able to regain full range of motion unless something is out of place. ...Read more

What can you do if you have a MCL tear of the knee?

What can you do if you have a MCL tear of the knee?

It heals: Mcl sprains will heal on their own after 6 weeks. In the meantime, a therapy program directed at range of motion, gentle strengthening and avoiding stress to the mcl is important. Wearing a hinged knee brace will also protect the mcl while it is healing. ...Read more

It's been 5 weeks since grade 2 and 3 MCL tear in both knees. How long does it take to heal itself?

It's been 5 weeks since grade 2 and 3 MCL tear in both knees. How long does it take to heal itself?

Depends: Depends on the type of tear and its location. Most tears from the medial femoral condyle have a good blood supply and oftentimes can heal with bracing, pt, and rice. If the tear is significantly displaced or a distal tear off the tibia, these do not usually do well and can sometimes warrant surgery. Either way an MRI is necessary and I do recommend appropriate orthopedic evaluation and treatment. ...Read more

What's the risk for playing football w/ full thickness tear (MRI) that occured to the MCL 4 weeks ago? My knee feels stable and there is minor pain.

What's the risk for playing football w/ full thickness tear (MRI) that occured to the MCL 4 weeks ago? My knee feels stable and there is minor pain.

Re- injury: Your orthopedic surgeon can help make the decision when you are ready to return to football.The obvious risk is re-injury. Where was it torn?( off the femur, mid- substance, tibia).Femoral MCL injuries heal quicker. Isolated injury? Your position(interior lineman,defensive back etc.)...skill positions may take longer. Are u wearing a functional knee brace? Have you practiced full- speed in it..? ...Read more

I had twisted knee i had almost complete tear of mcl&sprain of ACL when can I be back to sport?

Ask ur OrthopedicDoc: Better yet, go see a sports medicine specialist who can help you decide when to return to activity. Many variables to consider. How "almost complete" is "almost complete"? In what sport do you participate? Most important, how is your pain control? Bottom line: go see your doc. ...Read more

Had 1st degree MCL knee tear/sprain 2.5 weeks ago from ski. Can walk with 1 crutch but have pain while bending knee. Should i be alarmed? Meniscus?

Had 1st degree MCL knee tear/sprain 2.5 weeks ago from ski. Can walk with 1 crutch but have pain while bending knee. Should i be alarmed? Meniscus?

Maybe.: As long as it is an isolated mcl tear it will heal uneventfully. It could be a medial meniscus tear, though. A careful exam can usually distinguish between the two, but in some cases an MRI is needed to rule out meniscal injury. Pain with walking or bending can be seen with both. ...Read more

Can you tear acl/ MCL if a knee cap dislocation, x3weeks later still can't bend knee past 45* I've dislocated b4 and can't remember recovery last4ever.?

Can you tear acl/ MCL if a knee cap dislocation, x3weeks later still can't bend knee past 45*  I've dislocated b4 and can't remember recovery last4ever.?

Yes it's possible: You should see a sports medicine specialist whose expertise includes knee reconstruction; acl/mcl and patella dislocation are more commonly independent, but sometimes do occur from the same injury; your md will perform a thorough exam which often can diagnose the injury(ies), get x-rays to rule out fracture, likely order mri, recommend + oversee treatment; you might benefit from surgery. Good luc. ...Read more

Acl and mcl tear 9/2014, no surgery. Now having some mild knee pain, fullness and can't bend all the way. Normal inflammation? Brace help?

Acl and mcl tear 9/2014, no surgery. Now having some mild knee pain, fullness and can't bend all the way. Normal inflammation? Brace help?

Not normal: an injury that old typically will have healed by now. There may however be some scar tissue, or adhesions. They may cause irritation and limited motion. That could cause the swelling. A brace will not help. Have it evaluated by your doctor. You may need physical therapy. Alleve may help with the symptoms. ...Read more

Right knee pain: Hello. Have you ever tried Voltaren gel or Flector patches (diclofenac)? These treat dull, aching, throbbing pain. Have you tried lidoderm patches or lidocaine gel? These are used for sharp, stab, burn, pins/needles type pain. These gels and patches have to be prescribed. Do you wear any type of knee supports? Sleeves, braces.

I have gd III MCL tear lt knee and fracture lateral tibial condyle since 2 weeks. Can i move my leg or should I wear the knee immob 24 hours. ?

Follow directions: This injury can be unstable and proper immobilization will potentially avoid otherwise unnecessary surgery. My opinion is that your orthopedic surgeon will eventually put you into a hinged brace to allow for range of motion without side to side movement. Expect the first six weeks to be more strict guidelines and after six weeks guidelines will be lifted as healing dictates. ...Read more

My knee cracks everytime I bend down and as a dancer it hurts often but I have had it my whole life what is the cause ?

Patella / kneecap: The most common reason for knee "cracking" is softening of the cartilage of the patella (kneecap). This condition is called "chondromalacia patellae". It occurs more often is women and is thought to be related to anatomical and muscular variations in some individuals. Oftentimes specific exercises or knee braces can improve the condition. Surgery is rarely indicated. ...Read more

In dance I did a move & my knee popped out then into place,and months later when I was stretching.Now my knee cracks constantly. What could this be?

Patella malalignment: Sounds like you had knee cap (patella) dislocations. If the knee cap tracts slightly lateral to where it should, it will tend to cause a lot of noise and over time time wear down the cartilage (chondromalacia) as well as risk that it might pop out. Strengthening the inner thigh muscles (adductors) will help improve the patella alignment. Physical therapy is recommended. ...Read more

When I straighten my right leg, my knee locks, and once I bend it my knee cracks, it's painful and also hurts when standing sometimes?

Knee cap tracking: It sounds like you are having problems with knee cap tracking or subluxating. It is common for young females to have loose knee caps that get slightly off tack and cause locking and popping. This could also be cartilage damage or meniscus tearing. You should be evaluated by a knee specialist and possibly get an MRI to make sure there isn't any cartilage damage or tearing. ...Read more
