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

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

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

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

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

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
