High-flexion knee prosthesis was introduced with the aim of obtaining higher degree of flexion and good survivorship in patients with high functional demands or those requiring squatting, kneeling, etc., which is more common in Asians. Based on all the research and experience with this prosthesis, it was concluded that high flexion designs meet the need of deeper degrees of flexion in selected sets of patients only. Results were equal and comparable to the traditional standard posterior-stabilized total knee arthroplasty design and superior to it in terms of gaining more flexion and fulfilling activities, such as squatting, kneeling, and sitting cross-legged.
高屈曲膝关节假体的引入旨在满足功能需求较高或需要蹲、跪等动作的患者获得更高屈曲度和良好生存率的需求，这在亚洲人中更为常见。基于对这种假体的所有研究和经验，得出的结论是，高屈曲设计仅满足特定患者群体对更大屈曲度的需求。其结果与传统标准后稳定型全膝关节置换术设计相当，在获得更多屈曲度和完成诸如蹲、跪和盘腿坐等活动方面优于传统设计。
