S83: Dislocation, sprain and strain of joints and ligaments of knee
S83.4: Sprain and strain involving (fibular)(tibial) collateral ligament of knee
A sprain and strain involving the fibular and tibial collateral ligament of the knee is an injury that specifically affects the ligaments located on the sides of your knee. These ligaments help stabilize the knee joint and keep it moving correctly. This type of injury occurs when these ligaments are overstretched or torn, which can happen when the knee is twisted or hit forcefully. Common symptoms include pain and swelling in the knee, trouble bending or straightening the knee, and feeling like the knee is unstable or "gives way." This injury can occur as a result of a sudden twist or movement, especially during physical activities such as sports. Over time, if left untreated, this injury can lead to chronic knee instability and increased risk for further knee injuries.
