Background: Anterior cruciate ligament reconstruction (ACL) is one of the most common orthopedic procedures performed worldwide. Many studies have reported results of single- and double-bundle ACL reconstruction with regard to long-term follow-up; however, few have examined the outcomes of the early postoperative period.
Objective: This study was undertaken to evaluate early postoperative clinical outcomes after ACL reconstruction.
Material and Method: A retrospective study was carried out between April 2004 and February 2016. A total of 183 isolated ACL-injury patients underwent primary ACL reconstruction using patellar tendon bone and hamstring tendon. Demographic data and complications, including length of hospital stay (LOS) and operative time, were recorded.
Results: The mean age of the 183 patients was 28.52+7.43 years. Most of the subjects were male, single, and employed, with no underlying diseases. The mean + SD of BMI was 24.34+3.36 kg/m2. The main cause of surgery was injury resulting from accidents sustained while playing sports. The average operative time was 144.49+47.35 minutes, and LOS ranged from 3 to 23 days (mean + SD = 7.34+2.43 days). The majority of the patients underwent single-bundle ACL (92.2%) and bio absorb screw was most commonly used for tendon fixation. Medial meniscus tear (MM) was the most common injury, accounting for 59.1% of cases, whereas no lateral meniscus (LM) tear was observed in 64.0% of subjects. ACL reconstruction due to sports injury was more prevalent in younger patients than in older ones (p-value = 0.019), and a significant correlation between time after injury and meniscus tear was identified (p-value = 0.017).
Conclusion: ACL surgery was most commonly associated with sports injury and was most prevalent in younger patients. Operative times, LOS and complications in early postoperative outcomes were not significantly different in single- and double-bundle cases. More research is needed to assess early postoperative rehabilitation and long-term follow-up.
