Biomechanical Evaluation of a Novel Bionic Hip Prosthesis Designed for Optimized Load Transfer and Initial Stability
The irreversible subsidence displacement of the BHA prosthesis was below the interface failure threshold of 1.5 mm, and secondary fixation was accomplished at 100,000 loading cycles. The average failure load was approximately 6.4 times body weight, much higher than the daily load range of hip joints. The BHA prosthesis suggests potential for adequate axial initial stability to facilitate bone ingrowth, which is expected to reduce revision rates in patients.
