Clinical Description

Definition

M25.861 is used to classify joint disorders that do not fall under more specific categories but are localized to the right knee. This may include a range of conditions that affect the knee joint's structure and function, leading to pain, swelling, and reduced mobility.

Common Conditions Associated with M25.861

1. Patellofemoral Pain Syndrome (PFPS): This condition is characterized by pain around the kneecap (patella) and is often exacerbated by activities such as climbing stairs or sitting for prolonged periods[3][6]. PFPS is common among athletes and can result from overuse, muscle imbalances, or biomechanical issues.

2. Osteoarthritis: While not specifically coded under M25.861, osteoarthritis can manifest as "other specified joint disorders" when the typical degenerative changes are not clearly defined. Symptoms include joint stiffness, pain during movement, and swelling[5].

3. Bursitis: Inflammation of the bursae (small fluid-filled sacs that cushion the knee joint) can lead to pain and swelling, particularly on the outer side of the knee[4].

4. Tendinitis: Inflammation of the tendons around the knee, such as patellar tendinitis, can also be classified under this code if it does not fit into more specific categories[6].
