AI Article Synopsis
- There is a notable lack of research on revision ACL reconstruction in nonathletic patients, despite the high incidence of ACL injuries in this group compared to athletes.
- A retrospective study of 856 nonathletic patients revealed a symptomatic revision rate of 5.9% and a revision ACL reconstruction rate of 3.9%, largely due to graft rupture and laxity.
- Post-revision, patients exhibited significant improvement in knee function scores, particularly those who underwent revision within a year of initial symptoms, indicating that timely intervention may lead to better outcomes.
Article Abstract
Background: There is considerable literature about revision anterior cruciate ligament (ACL) reconstruction in athletes vut there is little published evidence about the same in the nonathletes. The injury itself may remain underdiagnosed and untreated in nonsports persons. This study highlights the high incidence of ACL injury in the nonathletic patient cohort, revision rates, and the outcomes of revision ACL reconstruction.
Materials And Methods: 856 nonathletic patients who underwent primary ACL reconstruction were included in this retrospective study. Patients were asked on phone whether they had undergone revision surgery and whether they had symptoms severe enough to seek reintervention. Clinical assessment and preoperative and postoperative International Knee Documentation Committee (IKDC) and Lysholm scoring were used to followup patients who underwent revision intervention.
Results: Clinically, symptomatic revision rate was 5.9% (51 out of 856 patients), and 33 out of these 856 patients (3.9%) underwent revision ACL reconstruction. The reasons for revision were rupture of the previous graft in 21 and laxity (incompetence) of the graft in 12 patients. The mean preoperative and postoperative IKDC scores were 44.1 and 69.8, respectively, and the improvement was statistically significant ( < 0.001). The IKDC score following revision ACL reconstruction was significantly better in those patients who underwent revision <1 year following the onset of recurrent symptoms ( = 0.015). Meniscal tears were present in 47.6%, and chondral injuries were seen in 33.3% of patients. The tibial tunnel positioning was abnormal in 70% of patients. Femoral tunnel positioning was aberrant in all the patients.
Conclusions: The revision rate of primary ACL reconstruction of 5.9% in nonathletes and revision ACL reconstruction rate of 3.9% are similar to the reported revision rates of 2.9%-5.8% in athletic patients. Similar to athletes, suboptimal tunnel placement is the major contributor to failure in nonathletes also.

Background: Wearable activity-measurement devices are increasingly popular among the public, but there is little information regarding their use among patients undergoing sports medicine procedures. The purpose of this study was to compare accelerometer-measured data with traditional patient-reported measures and to determine the trajectory of physical activity from before surgery to 1 year after anterior cruciate ligament reconstruction.
Materials And Methods: Adult patients undergoing primary anterior cruciate ligament reconstruction were enrolled in this prospective cohort pilot study.

Background: Optimal perioperative pain management is unknown for adolescent patients undergoing anterior cruciate ligament reconstruction (ACLR). The study aimed to determine the association of nerve blocks with short- and long-term pain outcomes and factors influencing self-reported neurological symptoms.
Methods: We performed a multisite, prospective observational study of adolescent patients undergoing ACLR.

Purpose: To investigate the failure rate, predictive factors associated with failure and clinical outcomes after a two-stage surgery; meniscus repair followed by subsequent anterior cruciate ligament (ACL) reconstruction (ACLR).
Methods: Patients with a concomitant traumatic meniscus tear and ACL injury who underwent a two-stage surgery between January 2015 and January 2021 were identified. The primary outcome was meniscal repair failure, defined as a reoperation (re-repair or resection).

Background: Some patients submitted to isolated ACL reconstruction may have symptomatic postoperative rotational instability. The objective of this study was to evaluate a population with mild rotatory instability after ACL reconstruction, which was submitted to an isolated extra-articular procedure.
Methods: Patients submitted to an isolated extra-articular procedure after ACL reconstruction were retrospectively evaluated.
Association Between Autograft Choice and Psychological Readiness to Return to Sport After ACL Reconstruction.

Background: It has been demonstrated that an athlete's psychological readiness contributes to one's ability to successfully return to sport (RTS) after anterior cruciate ligament (ACL) reconstruction. However, the effect of graft choice on psychological readiness is not yet understood.
Purpose/hypothesis: The purpose of this study was to evaluate the association between graft choice and an athlete's psychological readiness to RTS.
