This utility model discloses a patellar strap, comprising a strip-shaped body of elastic material. The body includes a first connecting part, an active part, and a second connecting part connected in sequence, such that the first and second connecting parts are connected to form a ring-shaped structure that fits below the knee. The active part has an upper band and a lower band. In use, the upper band fits against the patellar tendon, and at least a portion of the upper band is positioned higher than the positions of the first and second connecting parts. This patellar strap employs a partially open structure in its body. By utilizing the cooperation of the upper and lower bands, it ensures good protection for the knee while cleverly lowering the connection point of the body below the popliteal fossa, reducing wearing pain and effectively alleviating the problem of low wearing comfort in existing patellar straps.
