Sprained Knee Recovery Time
A knee sprain is considered healed when theres no more pain or swelling, and you can move your knee freely.
Many grade 1 and 2 knee sprains heal within two to four weeks. People who need surgery, however, may take as long as four to six months to recover.
About 80 to 90 percent of people with ACL injuries and 80 percent of those with PCL injuries will experience a full recovery. MCL and LCL sprains tend to heal quite well. However, some people with sprained ACL or PCL ligaments can develop arthritis in their knee over time.
Three Ways To Treat A Pop In The Knee
While the above orthopaedic conditions should be directly diagnosed and treated by a specialist, we have provided a few common recommendations knee doctors make when knee popping occurs. Talk to your physician before attempting to treat any injury yourself.
R.I.C.E.: For many injuries, to the knee or another part of the body, doctors suggest using the R.I.C.E. first. Rest, ice, compression, and elevation can reduce inflammation and pain and promote faster healing.
Proper immobilization: In addition to rest and compression, your physician may advise that you use a brace to prevent your knee from moving and to help you reduce discomfort. Depending on the type of brace and the particular patients living conditions, crutches may also be prescribed.
Rehabilitation exercises: Sometimes, a pop in the knee indicates instability, and thus the knee requires stronger surrounding muscles to support it during activity. Strengthening rehabilitation exercises, either given by your knee specialist or a physical therapist, can assist in stabilizing the area. While performing these activities, make sure to report any sensations of discomfort to a medical professional immediately. On a similar note, do not exercise too much at once, as overexertion of the area may worsen the condition.
Arthritis Symptoms Associated Knee Crepitus
Crepitus caused by knee arthritis is often accompanied by other symptoms, such as:
- Pain while walking or bending the knee
- Knee stiffness that improves with gentle stretching or exercise
- Knee tenderness or soreness, most commonly on the inside of the knee
- Occasional swelling of the knee
Many things can cause the creaking or crunching sensation while flexing and extending the knee. A doctor can conduct a clinical exam to determine if knee symptoms are caused by arthritis or another something else, such as patellar motion.

Acl Tears: The Season
Orthopedic surgeon F. Winston Gwathmey Jr., MD, specializes in sports medicine. He shares that the anterior cruciate ligament tear is the most noticeable knee pop that you won’t be able to walk off. An ACL tear isnt as common as other knee injuries, but it can still happen.
Most ACL tears are non-contact, meaning that nothing collides with the knee to cause the injury. Your knee needs to be in a certain position and receive the correct amount of force to tear the ACL. You may hear a pop and then youll feel it immediately. You’ll fall to the ground as your knee gives out. It’ll feel like someone tackled you. Since the ACL has a rich blood supply, the knee swells quickly and gets big.

What To Do If You Dislocate Your Kneecap
A dislocated kneecap is not usually serious and will often pop back into place by itself.
But it’s still a good idea to get it checked by a health professional:
- if your kneecap has gone back into place by itself go to your nearest urgent treatment centre or A& E
- if you cannot get to hospital without being in severe pain, you should call an ambulance do not try to put the cap back in place yourself
While you’re on your way to hospital or waiting for an ambulance, sit still with your leg in the most comfortable position.
A Knee Ligament Injuries
The most common knee twisting injury is a ligament sprain. When the knee twists too far, one or more of the ligaments may be placed under too much tension and as a result over-stretch. There are three different grades of sprain depending on the severity of the knee twisting injury.
- Grade 1: None, or very few of the ligaments fibres are actually torn, they have just been over-stretched
- Grade 2: Some of the fibres have been torn but the ligament is still intact
- Grade 3: The entire ligament has torn, aka complete rupture
The medial and lateral collateral ligaments sit on the sides of the knee joint, the medial collateral ligament on the inner side and the lateral collateral ligament on the outer side of the knee.
The cruciate ligaments control how much the knee bones glide forwards and backwards so are often overstretched with a twisted knee. The ACL is the most common knee ligament injury.

A Hit From The Side Can Injure Both The Medial Collateral Ligament And The Anterior Cruciate Ligament
So most patients will say, I got hit from the side. I felt a pop and then my knee became unstable, so that would be an injury here to the medial collateral ligament on the inside, which is a stretching injury. And then a tearing injury on the anterior cruciate ligament, which is in the middle of the knee, that creates stability for rotation deformity so those are two things to consider if you do feel a pop, particularly after a high impact. Thats something to consider.
You should go see an orthopedic surgeon immediately. Ice the knee, keep it elevated. Try not to do any cutting, twisting and pivoting activities, but just go ahead and get evaluated by a physician just to confirm whether or not the ligament is injured.
Knee Pain And Popping Causes
Knee popping and clicking can be caused by a number of things. It may be something simple like the ligaments catching on a bony lump and “snapping” back in to place or gas bubbles popping. But in some cases, knee popping is linked to a more serious injury such as ligament or cartilage tear.
Knee clicking and popping noises in the knee usually fall into one of three categories:

You Cant Put Weight On It
If its immensely painful to stand or put any weight on your injured knee, theres definitely something serious going on.
Inability to bear weight after a knee injury could be caused by a fracture, bone contusion, cartilage injury or ligament tear, explains Dr. Brown. Initial treatment includes using crutches or a steerable scooter to take pressure off the injured limb and minimize additional damage to the knee.
If this sounds like you, listen to what your body is trying to tell you. Dr. Brown warns that the old adage of no pain, no gain doesnt apply in this situation.
He advises seeking orthopedic evaluation as soon as possibleeven that same day if you can.
After a minor injury like a twist or fall, you might not be able to put weight on your leg immediately. Thats not necessarily a cause for alarm, but if you dont feel like youve recovered within a few minutes, this could indicate something more serious.
Its similar to when you injure a wrist or ankle. If you fall on your wrist or twist your ankle, you may experience searing pain for a moment or two. When the injury isnt severe, youre able to shake it off and resume your life after a few minutes at the most. However, if youve experienced a sprain, the pain doesnt subside. Instead, it gets worse.

Causes Of Knee Sprains
Any activity that forces your knee out of its natural position can cause a sprain.
The ACL is often injured when you play a running or contact sport like soccer, basketball, football, or gymnastics, usually as a result of jumping or twisting suddenly.
It can also occur if you over-straighten your knee to an extreme degree or if you get struck by something in the knee or lower leg.
The PCL can be injured in a car collision when your knee hits the dashboard, or in a sport where the front of your knee is hit while its bent. Falling hard on your knee can also cause a PCL sprain.
You can sprain your LCL if you receive a blow to the inside of your knee. This is less common than the other types of sprains because your other leg protects this area.
An MCL sprain is usually caused by something hitting your leg from the side, or a fall that causes your lower leg to twist outward from your thigh.
Knee Pop And Pain Behind Knee Causes
There are numerous possibilities why you experience knee pop and pain behind knee. Many people often take these symptoms for granted due to their lack of information regarding the possible extent of damage these knee conditions might imply.

How A Sprained Knee Is Diagnosed
The doctor will test the ligaments by stressing the individual ligaments to see if theres any instability or if the joint is stable.
If you injure your knee, see a doctor as soon as possible. This is especially important if you cant stand up, feel as though your knee will collapse, or your leg looks swollen or bulgy.
The doctor will examine your knee, look for swelling and bruising, and ask you to move it around to determine your mobility. Theyll compare it to your uninjured knee.
Theyll also want to know what you were doing when the injury happened, whether you heard a pop, and how long it took to become painful.
You may also be given imaging tests. An X-ray will show if theres a broken bone, but other imaging methods allow the physician to see different, non-bony structures inside your knee. This includes the ligaments and other tissues that support it.
Knee sprains are rated by severity. An overstretched ligament is grade 1. A partially torn ligament is grade 2. A ligament thats severely torn or separated is considered grade 3.
The treatment your doctor recommends will depend on the severity of your injury and what part of your knee was damaged.
Knee Popping By Activity

Knee Popping When Extending: Knee popping when you straighten your knee is usually due to gas bubbles , plica syndrome or patellofemoral pain syndrome.
