A total knee arthroplasty system (total knee system) was developed by the authors (Y/S) with instrumentation for controlled soft-tissue balancing both in flexion and extension. The prosthesis was designed to take into consideration the kinematic aspect of full flexion. Vigorous daily postoperative rehabilitation was continued for four weeks. Results were good to excellent in all but two of 50 consecutive knee operations on 39 patients. A minimum of 90 degrees flexion was achieved in all cases, with a better average range of motion than those reported in the past. Four patients (six knees), achieved full squatting. The combination of three elements, prosthetic geometry, well-controlled soft tissue balancing for flexion and extension phases, and vigorous rehabilitation, is important for the recovery of range of motion.
作者（Y/S）研发了一种全膝关节置换系统（全膝关节系统），该系统配备了用于在屈伸过程中进行可控软组织平衡的器械。假体的设计考虑到了全膝关节完全屈曲时的运动学特点。术后持续进行了四周积极的日常康复训练。在对39例患者连续进行的50例膝关节手术中，除两例外，其余结果均为良好至优秀。所有病例均至少实现了90度的屈曲，平均活动范围比过去报道的更好。四名患者（六个膝关节）实现了完全下蹲。假体几何形状、屈伸阶段良好控制的软组织平衡以及积极的康复训练这三个要素的结合，对于恢复活动范围至关重要。
