We’ve all popped a joint at some point or another, as it usually means that you’re releasing trapped air bubbles. Some people may experience numbness or pain in their leg after popping a joint, such as their knee joint. When that occurs, it’s important to look further into the potential causes to gain insight into whether treatment is needed.

We’ll talk about potential reasons that your leg goes numb after popping your knee and how Excel Rehab & Sports can help.

Possible explanations for your leg going numb after your knee pops

Popping your knee joint shouldn’t be a cause of concern unless it’s accompanied by, or followed by, pain or numbness. When those symptoms occur, it’s time to talk to your doctor for a potential diagnosis of a medical condition or injury that could be behind them.

Here are some possible causes of your leg feeling numb or in pain after your knee pops:

• Ligament injury — There are several ligaments in your knee that can be strained or torn, but the lateral collateral ligament (LCL) is one of the most common. It runs along the outer side of the knee. Pain, inflammation and swelling are prevalent symptoms in ligament tears, but so is numbness, which may flare up after popping your knee. 
• Meniscus injury — Not only can the issue stem from a torn ligament, but torn cartilage is a possibility as well. A meniscus refers to the cartilage located on either side of the knee and works as a shock absorber and stabilizer for the joint. Microtears can develop in the menisci when your knee is twisted with force. It can cause a popping sound with movement followed by numbness or pain.
• Osteoarthritis — Damaged cartilage is a possible cause of numbness after your knee pops, which may be an early sign of osteoarthritis. This type of arthritis occurs when the cartilage of the knee joint gradually breaks down, causing the bones to rub together. You may feel numbness if your nerves become pinched due to pressure from the cartilage and bone.
