Total knee arthroplasty with patellar resurfacing produces an increase in anterior patellar strain up to three times that observed in controls. This increase is independent of surgical capsulotomy and is prominent at flexion angles greater than 30 degrees. Minor alterations in surgical technique do not affect the observed strain. Peak strains were seen at the extremes of flexion in all prostheses. The highest strains were recorded for the Total Condylar prosthesis throughout the range of motion. Although the difference was not statistically significant, the Insall-Burstein knee consistently produced higher strains than did the Robert Brigham knee throughout the functional range of motion (30-90 degrees). For the Robert Brigham knee, sectioning of the posterior cruciate ligament resulted in no significant change in the measured strains.
全膝关节置换术联合髌骨表面置换会使髌前应变增加，最高可达对照组观察值的三倍。这种增加与手术关节囊切开无关，且在大于30度的屈曲角度时较为显著。手术技术的微小改变不会影响观察到的应变。所有假体在屈曲极限时均出现峰值应变。在整个运动范围内，全髁型假体记录到的应变最高。尽管差异无统计学意义，但在整个功能运动范围（30 - 90度）内，Insall - Burstein膝关节产生的应变始终高于Robert Brigham膝关节。对于Robert Brigham膝关节，切断后交叉韧带并未导致测量应变出现显著变化。
