What is the McDavid 429X Hinged Ligament Knee Support?

The McDavid 429 X Hinged Knee Brace is a steel hinged knee brace on the inside (medial) and outside (lateral) of the brace which physically assist the knee bending while reducing rotational movement of the knee joint.  This dramatically reduces the pressure on the ligaments when bending the knee and aids rehabilitation. The hinges also do not over extend over the 180 degree which prevents hyper-extension of the knee joint. The McDavid 429X Knee Support also has 4 cross straps along the front of the product, which mimic the ACL And PCL ligaments. They tighten across the front of the knee joint, which when bends, provides slight elastic resistance to the bend of the knee.

The design of the hinges also helps disperse weight and pressure away from the knee, through the hinges and steel supports, and down onto the thigh and calf muscles, hugely increasing the time you can spend on your feet, in turn reducing the pain. The 429X Knee Brace would also provide a lot of support if you were to land on the legs with some force, the shock and vibrations that carry through the knee would get absorbed by the material and hinges on the brace.

The 429 X Knee Brace is made from 5mm Neoprene fabric which offers a combination of support, compression and heat retention, which aids rehabilitation and eases pain and swelling from around the knee. It is Latex free neoprene.

When can I use the McDavid 429X Hinged Ligament Knee Brace?

The McDavid 429X Hinged Knee Brace has a padded buttress with open patella to keep the knee cap in a central position when bending the knee. This will also relieve any tendonitis around the knee cap that will often be caused by Ligament damage. The McDavid 429X Knee Brace can be used for a plethora of different injuries, and due to its high level of support, is very popular for those suffering with Knee Ligament injuries, be it a complete rupture, tear or blow out of the ACL, PCL, MCL, or LCL. This is due to the strong hinges on the 429X Knee Support, only allowing the knees natural movement.

Skiers also favour the McDavid 429X Hinged Knee Brace, due to its comfortable design but rigid, high level support. An excellent injury prevention product for dangerous sport, coupled with being a brilliant product for post rehabilitation.

The McDavid 429X Knee Brace can also offer support to lower level injuries such as arthritis, or tendonitis, due to its comfortable warming material, it will help prevent the knee from seizing up. The soft buttress around the kneecap, provides pressure to the tendons helping relieve the symptoms of tendinitis, whilst keeping the kneecap correctly in place, aiding against patella tracking problems.

I purchased 2 of these braces and i have to say they are so uncomfotable to wear. The stiching inside the brace really rubs against your skin, also the hinges don't seem to stay in position. Not good
