Patellar stabilizers are devices designed to support and stabilize the patella, or kneecap, during physical activities. They help prevent excessive movement of the patella, which can lead to pain or injury. These stabilizers are often used by athletes or individuals recovering from knee injuries. Typically made from elastic materials, patellar stabilizers can be worn under clothing and are adjustable for a comfortable fit. They are commonly recommended for conditions like patellar tendinitis or chondromalacia patellae, where proper alignment of the patella is crucial for knee function and overall mobility.
