Pro: The compression sleeve functions similarly to the patellar/knee support brace; it provides support that makes you feel more secure while wearing the brace. It also may provide some relief from swelling around the knee.
Con: While the brace makes you feel more confident, it does not address the mechanics that cause your knee to have pain. If your knee has swelling, it will help reduce the swelling, but it does not address the cause of the swelling. Once you take off the brace, you will likely continue to have swelling.
Take away message: This Knee Compression Sleeve will help you feel more confident in practice, but it will not help your muscles control your knee (or kneecap) the right way to reduce pain or swelling.
