Geometric total knee prosthesis was applied for reconstruction of 70 destructive knee joints in 56 patients from November 1973 through March 1979. The average follow-up period extended to six years and seven months. Eleven patients had died and four could not be located. Eighty-one percent of the remaining arthroplasties disclosed little or no pain at the time of the review. Pain in the patellofemoral joints was an insignificant problem in this series. The absence of radiolucent zone at the tibial cement-bone interface was noted in only 20.4% of the roentgenograms. New formation or progression of radiolucent zone after six months was found in 36.7%. Displacement of the marker wires seen in serial roentgenograms existed in 51.0% of the knees. The tibial component was fractured in one patient.
1973年11月至1979年3月，采用几何全膝关节假体对56例患者的70个毁损膝关节进行重建。平均随访期延长至6年7个月。11例患者死亡，4例失访。在复查时，其余关节成形术中有81%几乎没有疼痛或完全没有疼痛。在本系列中，髌股关节疼痛并非重要问题。在X线片上，仅20.4%的病例在胫骨骨水泥-骨界面处未见透亮区。36.7%的病例在6个月后出现透亮区的新形成或进展。在51.0%的膝关节的系列X线片中可见标记线移位。1例患者的胫骨部件发生骨折。
