Knee Pain

Best ACL Knee Braces to wear after an ACL Injury

What is an ACL injury?

An ACL injury is a tear or sprain to the Anterior Cruciate Ligament (ACL), which is one of the major ligaments in the knee. The anterior cruciate ligament can be injured in several ways:

  • Changing direction rapidly
  • Stopping suddenly
  •  Slowing down while running
  • Landing from a jump incorrectly
  • Direct contact or collision, such as a football tackle

Signs and symptoms of an ACL injury usually include: 

  • A loud “pop” or a “popping” sensation in the knee
  • Severe pain and inability to continue activity
  • Swelling that begins within a few hours
  • Loss of range of motion
  • A feeling of instability or “giving way” with weight bearing.


Bracing is one of the treatment methods that doctors recommend for both nonsurgical treatment and post-surgical treatment of an ACL injury. Knee braces made specifically to enhance healing or reduce the risk of re-injury of an ACL injury are much better options that off the shelve knee braces that you see in stores.


Knees usually get injured when they move in an unusual way. Twisting the knee or bending it too sharply in medial or lateral directions can tear the ligaments that hold the knee in place. Limiting the range of motion of your knee will generally help prevent the overstretching or twisting of the knee. ACL knee braces provide support and stability to the knee preventing any such movement. This reduces the risk of reoccurrence of the ACL injury and also any damage to other knee ligaments like the PCL and MCL. A knee brace is also reported by a large number of users to aid in pain relief. With a plethora of options to choose from, here are our picks for the best ACL knee braces o the market today:

DonJoy Playmaker II Knee Brace


The Donjoy Playmaker II is a little longer than the standard knee supports on the market, with its long geared hinges running down the inside and outside of the knee. The main added benefit of the length of these hinges is the level of offloading support they offer. As the hinges are geared, they are also connected with each other, meaning the weight and pressure that travels through the leg, gets taken on by the hinges, and leaves the knee relieved. As the Donjoy Playmaker II Knee Brace is marginally longer than other braces, it has a slightly tapered thigh, which means the top of the product is a bit wider than the rest of the brace, opening up for your thigh for a supportive but comfortable fit. Due to the design of the Donjoy Playmaker II’s hinges, they do not allow for the knee to go over on itself, collapse, or even twist, so all of the dangerous unnatural movement is stopped, and the regular range of movement is not restricted. It is therefore ideal for those affected by an ACL injury, or other knee ligaments damage.
