OBJECTIVE

To evaluate the early clinical results of total knee arthroplasty (TKA) with JOURNEY prosthesis.

METHODS

From September 2006 to May 2007, TKA with JOURNEY prosthesis was used to treat 32 patients in ATOS Clinic, Germany. There were 21 males and 11 females, aged 40-84 years old (average 65.6 years old). The locations were left knee in 13 cases and right knee in 19 cases, including 5 cases of traumatic arthritis, 19 cases of osteoarthritis and 8 cases of rheumatoid arthritis. All patients had pain and limited range of motion (ROM) of knee. MRI scanning showed that cartilage and meniscus damaged in all cases. The disease course was 1 to 4 years (average 2.2 years). The CPM practice started 2 days after operation.

RESULTS

The operative time was (75.0 +/- 21.7) minutes. The blood loss was (280 +/- 130) mL. All incision healed by first intention. Thirty-two patients were followed up 12 to 18 months (average 14.2 months). Hydrarthrosis occurred in 8 cases at 3-6 months postoperatively. Femur paraprosthetic fracture and implant dislocation occurred at 1 week and at 6 months in 2 cases, respectively. There were statistically significant differences in KSS score between preoperation and 3, 6, 12 months after operation (P < 0.05), between 3 months and 6, 12 months after operation (P < 0.05); there was no statistically significant difference in KSS score between 6 months and 12 months after operation (P > 0.05). There were statistically significant differences in pain score between preoperation and 3, 6, 12 months after operation (P < 0.05), and in ROM between 3 months and 6, 12 months after operation (P < 0.05). There was no statistically significant difference in ROM between preoperation and 3 months after operation (P > 0.05).

CONCLUSION

It is a simple way to TKA with JOURNEY prosthesis, which has a good results in early follow-up period.

目的

评估使用JOURNEY假体进行全膝关节置换术（TKA）的早期临床效果。

方法

2006年9月至2007年5月，德国阿托斯诊所使用JOURNEY假体对32例患者进行TKA治疗。其中男性21例，女性11例，年龄40 - 84岁（平均65.6岁）。部位为左膝13例，右膝19例，包括创伤性关节炎5例、骨关节炎19例、类风湿关节炎8例。所有患者均有膝关节疼痛及活动度（ROM）受限。MRI扫描显示所有病例均有软骨及半月板损伤。病程1至4年（平均2.2年）。术后2天开始进行CPM练习。

结果

手术时间为（75.0±21.7）分钟。失血量为（280±130）mL。所有切口均一期愈合。32例患者随访12至18个月（平均14.2个月）。术后3至6个月有8例发生关节积液。2例分别于术后1周和6个月发生股骨假体周围骨折及假体脱位。术前与术后3、6、12个月的KSS评分差异有统计学意义（P<0.05），术后3个月与6、12个月的KSS评分差异有统计学意义（P<0.05）；术后6个月与12个月的KSS评分差异无统计学意义（P>0.05）。术前与术后3、6、12个月的疼痛评分差异有统计学意义（P<0.05），术后3个月与6、12个月的ROM差异有统计学意义（P<0.05）。术前与术后3个月的ROM差异无统计学意义（P>0.05）。
