BACKGROUND
We investigated the accuracy of targeted resection thickness in patients undergoing primary Total Knee Arthroplasty (TKA) using the ROSA robotic system.
METHODS
Calliper measurements of the distal femur (DF), proximal tibia (PT), and posterior condyles (PC) were taken in 44 patients from June 2023 to January 2024.
RESULTS
Planned and actual resection depth difference was 0.67 mm ± 0.6 mm (mean ± SD) (p = 0.217) and 0.94 mm ± 1.15 mm (p = 0.4) for medial and lateral DF, 0.93 mm ± 0.81 mm (p = 0.001) and 0.89 mm ± 0.8 mm (p = 0.008) for medial and lateral PT, and 1.1 mm ± 0.97 mm (p = 0.001) and 1.04 mm ± 0.79 mm (p = 0.001) for medial and lateral PC, respectively.
CONCLUSION
The ROSA robotic system can achieve a high degree of accuracy for planned resection thickness. Results are valid only for the imageless ROSA TKA in patients with primary knee osteoarthritis.
背景
我们使用ROSA机器人系统研究了初次全膝关节置换术（TKA）患者目标切除厚度的准确性。
方法
在2023年6月至2024年1月期间，对44例患者的股骨远端（DF）、胫骨近端（PT）和后髁（PC）进行了卡尺测量。
结果
内侧和外侧DF的计划切除深度与实际切除深度之差分别为0.67 mm±0.6 mm（均值±标准差）（p = 0.217）和0.94 mm±1.15 mm（p = 0.4），内侧和外侧PT分别为0.93 mm±0.81 mm（p = 0.001）和0.89 mm±0.8 mm（p = 0.008），内侧和外侧PC分别为1.1 mm±0.97 mm（p = 0.001）和1.04 mm±0.79 mm（p = 0.001）。
结论
ROSA机器人系统能够实现计划切除厚度的高精度。结果仅对原发性膝关节骨关节炎患者的无图像ROSA TKA有效。
