Knee arthroplasty for treating degenerative femoral intercondylar fossa impingement syndrome / 中国组织工程研究

ABSTRACT

BACKGROUND:Traditionaly, non-surgical treatment was used to treat degenerative femoral intercondylar fossa impingement syndrome, but it can cause function loss of cruciate ligament, or knee instability. With the development of medical technology, more and more views believed that ligament damage and combined with other knee structural damage should receive surgery as soon as possible. OBJECTIVE: To investigate the repair effect of knee arthroplasty for treating degenerative femoral intercondylar fossa impingement syndrome, and compare with AO cannulated screw fixation. METHODS:A total of 72 patients with degenerative femoral intercondylar fossa impingement syndrome were equaly and randomly divided into treatment group and control group. Patients in the control group were treated with open AO cannulated screw fixation, and patients in the treatment group were subjected to knee arthroplasty. At 7 days after treatment, repair effect was evaluated. Before treatment and 7 days after treatment, knee function was assessed by using Lysholm knee Scoring Scale and the international knee documentation committee knee evaluation form. Al patients were folowed up for 6 months after treatment to investigate the occurrence of complications. RESULTS AND CONCLUSION:The surgery was successfuly completed in al patients. At 7 days after treatment, the excelent and good rate was 94% in the treatment group and 75% in the control group. The excelent and good rate was significantly higher in the treatment group than in the control group (P < 0.05). Lysholm scores were significantly greater, but the international knee documentation committee knee evaluation form scores were significantly lower at 7 days after treatment compared with that before treatment in the treatment group (P < 0.05). Simultaneously, Lysholm scores and the international knee documentation committee knee evaluation form scores were significantly better in the treatment group than in the control group at 7 days after treatment (P < 0.05). During 6-month folow-up, wound infection, intra-articular infection, joint pain, and deep vein thrombosis were significantly less in the treatment group than in the control group (P < 0.05). These findings indicate that knee arthroplasty for degenerative femoral intercondylar fossa impingement syndrome can improve short-term efficacy, effectively restore knee function and reduce the incidence of postoperative complications.
