Be the first to review this product

This mode of treatment for MCL tear and LCL tear treatment stands out from the rest thanks to its active thigh cuff that adjusts to changes in the muscle throughout its range of motion. Also adding to the appeal of the hinged MCL knee brace is its low-profile, lightweight fit, which makes this brace suitable for low-contact sports like soccer, basketball or running.

Detailed Description

LCL and MCL Knee Brace

This brace for medial collateral ligament sprain treatment (MCL) and lateral collateral ligament sprain treatment (LCL) can also help with injuries to the posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL), in addition to combined instabilities or post-operative care. Find more braces for MCL and LCL injuries.

The brace works well as a prophylactic knee brace that helps prevent an injury from occurring in the first place, and as a functional knee brace for recovery from ligament damage. The soccer knee brace also works as a pre- or post-op knee brace. (See more such products.)

This MCL and LCL knee brace features the patented active thigh cuff (ATC) that can adjust to changes in the muscle as one goes through motion. The ATC also adjusts to changes due to muscle atrophy or hypertrophy as well as weight gain or loss. This feature also makes this style of collateral ligament knee support less restrictive than many other knee stability braces. BraceAbility also offers a rigid-top version of this brace that is ideal for contact sports like football or hockey.

Following a collateral injury one may need some time off the feet as part of LCL or MCL sprain treatment or possibly even surgery. During this time, one will likely experience swelling and muscle atrophy (wasting), followed by the reduction of swelling and the rebuilding of muscle as one goes through physical therapy. The ATC feature of the soccer knee brace means it easily adjusts to such changes.

There are many features of this MCL knee brace for basketball and other sports that help keep it suspended on the leg, such as the active thigh cuff, silicone grips on the calf cuff, a lightweight design and its metal linkage hinge with integrated slide guard. The calf cuff is a posterior one, which reduces tibia pressure. This also reduces medial clearance issues.

The frame of this sports knee brace is made with an aerospace-grade aluminum that is strong but can be customized. This durable material is surprisingly lightweight, which is a boon in athletic activity. The linkage hinge tracks the knee axis, which helps with suspension as well as natural movement.

The knee brace for running and other low-contact sports is lined with compression-molded faux-suede padding for ultimate user comfort. This is an important element for those tasked with wearing a knee support for an extended period after a significant knee injury.

Treatment for MCL Tear and LCL Tear Injuries

The collateral ligaments are the ones on either side of the knee—the MCL on the inner side and LCL on the outer side—that control the sideways motion of it and protect it against unusual movements. These ligaments can be damaged by contact to the knee (most often) that pushes it sideways or a hard muscle contraction, as one might experience during a quick change in direction, such as a pivot.

While the MCL is more often injured than the LCL, if the LCL is injured, this typically comes with additional damage to the structures of the knee.

Initial treatment for sprains or tears to either of these ligaments involves getting pain and inflammation under control via ice and non-steroidal anti-inflammatory drugs, elevation and a limited period of rest.  Wearing a brace can protect against damaging motions or forces to the knee in addition to giving it a bit of a break. One can wear this functional brace during physical therapy to restore function to the knee and one's eventual return to sports

Surgery to repair isolated collateral ligament injuries are rare, with most instances of going under the knife being for instances of combined injuries. This functional knee orthotic can also help protect the knee before and after any such procedure.

Range of Motion Adjustments

This functional knee brace comes with standard 5 degree extension stops. Additional flexion and extension stops may be installed if they are prescribed by your physician or needed for optimal performance or fit of the brace. These should be inserted by the technician who fits your brace. Optional 0°, 5°, 10°, 20°, 30°, and 40° extension stops and optional 45°, 60°, 75° and 90° flexion stops are included with each brace. IMPORTANT: Both hinges must be set to same extension and/or flexion settings. For 0° extension limiting, 0° extension stops must be used.

Extension and flexion stop installation: 1. Twist off two desired extension or flexion stop (Figures 1 and 2). 2. Remove condyle pads and flex brace to 45 degrees to access the stop locations. Remove installed stops by removing the screws through the condyle cup hole. 3. Note the direction of the “hook” features which point forward. 4. Using the handle to assist insertion of the new stops, guide the stop down into position as shown in Figure 3. Do not twist off handle yet. Flexion stops go in the posterior of the hinge and extension stops go in the anterior part of the hinge. 5. Insert and securely tighten one silver screw per extension stop and 2 black screws per flexion stop. Twist off handle. 6. Cycle the brace through several flexions-extensions to ensure stop is positioned and functioning properly.

Application Instructions: 

  1. Unfasten straps: Attach each strap back onto itself to minimize tangling.
  2. Position brace on knee: While sitting down, step through the brace and flex the knee to approximately 45°. Align hinge centers with the top of the kneecap and position slightly behind midline of the leg. 
  3. Fasten straps: While maintaining the brace in line with the top of the patella, fasten straps 1-5 in sequence indicated on the strap tabs. Straps should be comfortably tightened to properly secure brace, do not over tighten. 
  4. Check fit: Stand up and walk around in the brace. Check to make sure that hinge centers are aligned with the middle of the kneecap or slightly above and positioned slightly behind midline of leg. It is normal for the brace to settle into position. Make adjustments as necessary to correct brace position and ensure a comfortable fit. 

If desired, install ATC pivot clip where the ATC components (top straps) cross. The pivot clip allows the ATC to pivot in the center during use and is there as an option if the crossing straps are moving too much or shift out of their proper place on the leg. Also included are the rigid ATC straps that can be used in place of the flexible straps already installed if additional rigidity is desired. 

Note: For PCL configuration, straps 1 & 2 and 4 & 5 are the same. The 3rd strap will need to be switched to the front and fastened on the front of the thigh.
