Analysis of Risk Factors and Surgical Strategy of Knee Traumatic Arthritis after Internal Plate Fixation in the Treatment of Tibial Plateau Fracture

Objective

To explore the risk factors and surgical strategies of knee traumatic arthritis after internal plate fixation in the treatment of tibial plateau fracture.

Methods

A total of 300 patients with tibial plateau fractures treated with internal plate fixation in our hospital from January 2019 to April 2021 were retrospectively analyzed. According to whether secondary knee traumatic arthritis occurred after operation, they were divided into control group and research group. The control group was nonsecondary knee traumatic arthritis (n = 231), and the research group was secondary knee traumatic arthritis (n = 69). Univariate and multivariate logistic regression analysis was used in this research.

Results

There were significant differences in fracture classification, injury method, osteoporosis, and the time from injury to operation between the two groups, and there are statistically significant differences between groups (P < 0.05). Fracture type, injury method, osteoporosis, and time from injury to operation were the influencing factors of tibial internal fixation, and there are statistically significant differences between groups (P < 0.05). Platform fracture was an independent risk factor for postoperative knee joint traumatic arthritis, and there are statistically significant differences between groups (P < 0.05). The HSS scores of both groups increased after operation, and there are statistically significant differences between groups (P < 0.05). No loosening of the prosthesis was found in all 69 patients with postoperative X-ray examination.

Conclusion

Fracture classification, injury mode, osteoporosis, and time from injury to operation are independent risk factors for knee traumatic arthritis in the treatment of tibial plateau fractures with internal plate fixation, incidence of knee trauma.

Cleavage Intercondylar Fracture of the Femur: A Case Report

Distal femur fractures account for less than 1% of all fractures and about 3 to 6% of all femoral fractures. Several classifications have been described but some types of distal femur fractures escape them such as the cleavage intercondylar fracture of the femur. To our knowledge, there have been only four cases reported in the literature. The authors report a case of a 32-year-old woman who presented at the emergency department with a cleavage intercondylar fracture of the left femur. The patient was treated with a long leg cast for 6 weeks, followed by physiotherapy and full weight-bearing. After 4 months, the evolution was favorable: the patient was asymptomatic and regained full knee range of motion. After 10 years of follow-up, there was no clinical or radiological evidence of knee osteoarthritis.
