The McDavid PSII Hinged Knee Brace (429) uses state of the art, lightweight materials to provide the maximum level of protection and support. This brace is ideal for assisting with recovery from lateral (LCL) and medial (MCL) collateral ligament injuries. It's also effective for healing and pain relief in anterior cruciate ligament (ACL) and cartilage problems. The PSII brace is very effective as a preventive measure, as well as remedial treatment.


How it works:

This brace is fitted with geared, aircraft grade aluminium, polycentric hinges on the inside (medial) and outside (lateral) parts of the brace. These hinges are 15% lighter, and slightly shorter than the A428 Pro Stabiliser Knee Brace. The hinges provide unrestricted 'normal' knee movement, but reduce painful rotation of the joint and tendons. Two stops prevent knee hyperextension. To stabilise the kneecap the PSII brace has a sewn-in patellar buttress. Compression from the buttress helps to ease the pain associated with patellar tendonitis. The PSII Knee Brace is easy to fit and simply pull it up into place over the knee using the straps, then fasten the top and bottom hook and loop closures.

Benefits of the PS II Hinged Knee Brace 429:

  • Helps to improve kneecap tracking
  • Provides support for the knee joint when bending
  • Helps to reduce stresses on the ligaments
  • Reduces pain related to rotational knee movement
  • Prevents knee hyperextension
  • Neoprene sleeve provides soft tissue compression to reduce pain and swelling
  • Retained warmth promotes healing
  • Open knee enables air flow for additional comfort
  • Reduces your chances of suffering a knee strain injury
  • Bone on bone issues due to cartilage wearing away

Satchels & Box Packaging

Most of our orders are sent with mailing satchels. With inflation, supply chain issues and the general increase in costs in almost every aspect of our business - the benefit of using satchels is that it lowers the weight and size of the parcel which keeps our cost down. This has allowed us to continue to offer free standard shipping.

Please note that sometimes parcels can get squashed during transit which cause your products packaging to get dented or slightly damaged.  The product will not be affected.

If you wish to avoid any risk of damage during transit or your purchase is a gift we recommend opting for our $1.50 box packaging option. You will find this option in the cart page after you add your items to cart.
