Detailed Description
History and current related studies Posterior cruciate ligament of the knee is an important structure to maintain stability of the knee, and can prevent backward displacement of the tibia, so the violence that causes the tibia to move backward can cause posterior cruciate ligament rupture. Tibial avulsion fracture of posterior cruciate ligament of the knee will lead to unstable posterior movement and rotation of the knee and accelerate the degeneration of the knee. Thus, maintaining the tension of posterior cruciate ligament and restoring anatomical stability of the knee affect early rehabilitation and surgical treatment, and are the difficulty and key point of sports medicine.
When tibial avulsion fracture of posterior cruciate ligament of knee is treated with open reduction and rivet fixation, hollow screw fixation or arthroscopic reconstruction of the posterior cruciate ligament, plaster fixation is often required for flexion and extension exercises. However, the importance of early tension reconstruction of posterior cruciate ligament is often ignored. How to select the fixation method for tibial avulsion fracture of posterior cruciate ligament and how to restore the anatomical stability of the joint are still controversial. In recent years, with the development of surgical techniques and instruments and the popularization of the concept of precision surgical treatment, high requirements are put forward for the new fracture fixation methods.
Data collection, management, analysis, open access
- Data collection: Case report forms will be collected, processed using Epidata software (Epidata Association, Odense, Denmark), collated, and then recorded electronically by data managers using a double-data entry strategy.
- Data management: The locked electronic database will be accessible and locked only by the project manager. This arrangement will not be altered. The Cangzhou Central Hospital, China will preserve all of the data regarding this trial.
- Data analysis: A professional statistician will statistically analyze the electronic database and will create an outcome analysis report that will be submitted to the lead researchers. An independent data monitoring committee will supervise and manage the trial data, ensuring a scientific and stringent trial that yields accurate and complete data.
- Data open access: Anonymized trial data will be published at www.figshare.com.
Statistical analysis
- Statistical analysis will be performed using SPSS 13.0 software (SPSS, Chicago, IL, USA) and will follow the intention-to-treat principle. Normally distributed measurement data will be expressed as means ± standard deviation and minimums and maximums. Non-normally distributed measurement data will be expressed as the lower quartile (q1) and median and upper quartiles (q3). The count data will be expressed as a percentage.
- Normally distributed data of HSS and Lysholm Knee Scoring Scale scores at preoperative, postoperative 3 and 12 months will be analyzed with one-way analysis of variance and least significant difference. Non-normally distributed data will be analyzed using Kruskall-Wills H test and Cohen's d test. Patient satisfaction and incidence of adverse reactions at postoperative 3 and 12 months will be compared using McNemar χ2 test. The significance level will be α = 0.05.
