The High flex knee ( High Flexion Knee) is a boon to patients seeking increased function after a TKR. It allows activities which require deep knee bend like stair climbing, squatting, kneeling, gardening which are not possible with conventional knee replacements. Muslims can kneel for Namaz (prayer). High flexion is achieved through a combination of prosthetic design, patient selection, surgery technique and physiotherapy. High flex implants include fixed and mobile bearing (rotating platform) options. To get a no obligation quote for a flexible knee, please fill the Contact us form
In order to benefit from a high flex knee replacement a few criteria should be met
a) Osteoarthritis is the main indication. If it is rheumatoid arthritis, bony destruction should not be advanced.
b) Revision knees are not suited for high flexion
c) Ankylosed knees or fused knees cannot be replaced with a high flexion knee.
d) The thigh calf index should be above 90 degrees.
e) The patient should be motivated to achieve deep knee bending and should participate in aggressive post operative physiotherapy.
Some activities possible only with the full bending or high flex knee replacements are shown below.
