 The Birmingham Knee Replacement (BKR)
Mr McMinn has designed the Birmingham Knee Replacement (BKR) to closely mirror the natural kinematics of the knee.
Studies have shown that 20% of patients with regular Total Knee Replacements (TKRs) are dissatisfied with their knee function in the months and years following operation. These knee implants fail to replicate natural knee anatomy, causing pain and tightness at the front of the knee, limited leg flexion and difficulty in day to day activities. Patients with regular TKRs find they have to give up their active lifestyles following surgery.
Mr McMinn has developed the BKR as an alternative knee replacement, which has allowed many patients to be extremely active following surgery. Orthopaedic research reveals that during flexion, the knee moves in a subtle spiral motion. To replicate this natural motion, the BKR is designed with spiral condyles. These spirals offer congruence deep into flexion, providing superb stability, accurate patellar tracking, and improved knee function following surgery.
Because the BKR is designed to emulate the natural knee, patients find that they have the confidence not only to perform essential everyday activities but also to pursue their more rigorous hobbies such as golf, skiing, tennis and waterskiing.
The BKR also boasts superb wear characteristics compared to competitor devices. Since it has a higher congruence and contact area, there is less wear on the implant over time.
The BKR is demonstrating good results at early follow-up in terms of:
-
Better patient satisfaction
-
Excellent patellar tracking, mirroring the natural knee kinematics
-
An increased range of flexion
