This research sought to carry out a comparative study observing the clinical and radiographic analysis of primary prostheses of the type TC3 Depuy Johnson with or without a stem during a short-term follow-up.
The sample was divided into three groups: Group 1 (with stem), Group 2 (without stem) and Group 3 (mixed). Patients were evaluated to assess whether the implants were loosening and a clinical analysis was performed.
Preoperative deformities were predominantly considered severe. The total range of motion in the postoperative period was above 96.7° in the three groups. In the postoperative period, the femoral-tibial angle oscillated on average between 5 to 6° valgus. There was no record of implant loosening for cases treated with stem, and the incidence of loosening was 14.3% for the group without stem and 16.7% among cases in the mixed group.
In general, preoperative deformities were considered severe. In the postoperative period, the total range of motion was above 96.7°. The postoperative femoral-tibial angle obtained an average of 5 to 6° valgus. There is no significant difference in implants loosening in the three groups.
本研究旨在进行一项比较研究，观察在短期随访期间带柄或不带柄的Depuy Johnson TC3型初次假体的临床和影像学分析。
样本分为三组：第1组（带柄）、第2组（不带柄）和第3组（混合组）。对患者进行评估以确定植入物是否松动，并进行临床分析。
术前畸形主要被认为是严重的。术后三组的总活动范围均高于96.7°。术后，股胫角平均在5至6°外翻之间波动。带柄治疗的病例未记录到植入物松动，不带柄组的松动发生率为14.3%，混合组病例的松动发生率为16.7%。
总体而言，术前畸形被认为是严重的。术后，总活动范围高于96.7°。术后股胫角平均获得5至6°外翻。三组植入物松动情况无显著差异。
