Total Knee Replacement is a highly successful procedure that corrects deformity, restores mobility, and greatly enhances quality of life. However, conventional total knee implants usually allow knee flexion only up to 120–125 degrees. For individuals who require deeper bending of the knees for cultural, recreational, or daily activities, High Flex Total Knee Replacement offers an advanced and more comfortable solution.
How much flexion do we actually need?
Many routine movements demand the ability to bend the knee beyond 125 degrees.
• Climbing stairs: 75–140 degrees
• Sitting and standing from a chair: 90–130 degrees
• Activities such as gardening, golfing, and kneeling for prayer: 130–150 degrees
In societies where sitting cross-legged or squatting is a common practice, achieving high flexion after surgery becomes even more important.

Dr. Vivek Mittal, a leading total knee replacement surgeon in Delhi NCR, specializes in advanced High Flex Total Knee Replacement techniques that help patients comfortably resume such movements after surgery. Patients from across India looking for an expert knee replacement surgeon in Delhi or searching for a reliable knee replacement surgeon near me often choose his expertise for long-lasting, natural-feeling results.
Benefits of High Flexion Knee Implants
Conventional Total Knee Replacement did not allow patients to sit cross-legged or squat comfortably. Modern High Flexion Knee Implants, however, are specifically designed to support deep flexion up to 150–155 degrees, enabling patients to resume natural sitting positions and cultural postures after surgery.
With the expertise of the best knee replacement surgeon in Delhi NCR, patients can:
• Sit cross-legged or squat safely (depending on pre-operative flexibility)
• Achieve greater comfort in everyday activities
• Regain a more natural range of motion
• Enjoy improved quality of life with restored knee function
It’s important to note that the ability to achieve deep flexion depends not only on the implant or the skill of the knee replacement surgeon in Delhi NCR, but also on the patient’s pre-surgery condition, muscle strength, and commitment to physiotherapy.
Are You a Candidate for High Flex Total Knee Replacement?
If you had good flexibility before surgery and are motivated to follow proper rehabilitation, you may be an ideal candidate for High Flex Total Knee Replacement. Factors influencing candidacy include:
• Pre-operative range of motion
• Early and intensive physiotherapy after surgery
• Weight, age, and activity level
The surgical principles are similar to conventional total knee replacement, but the implant design allows deeper and safer bending of the knee. To know whether this procedure suits your lifestyle, you should consult an experienced total knee replacement surgeon in Delhi NCR like Dr. Vivek Mittal, who has helped numerous patients regain complete freedom of movement through advanced high-flexion implant techniques.
