Brief summary

Conflicting evidence and inconsistent criteria regarding Return to Sport (RTS) following Anterior Cruciate Ligament (ACL) highlights the necessity for further investigation into ACL Reconstruction (ACLR), and factors that influence RTS. The aim of this study is to investigate the correlation between an objective measure of quadriceps and hamstring isometric muscle strength and subjective assessment of knee joint function and perceived readiness to RTS at 6 months and 10 months after ACLR.

Interventions

Anterior Cruciate Ligament Reconstruction (ACLR) The ACLR will be performed using a medial portal femoral tunnel approach. A hamstring autograft will be harvested from either ipsilateral or contralateral side and fixed in the femoral tunnel using an endobutton, and within the tibial tunnel using an intracortical tibial screw, plus/minus a staple, as necessary. Patients will be recruited for study participation 3 months post ACLR, and as such the ACLR is not conducted as part of this study. The aim of this study is to investigate the correlation between an objective measure of quadriceps and hamstring isometric muscle strength (LSI) and subjective assessment of knee joint function and perceived readiness to Return to Sport (RTS) at 6 months and 10 months post ACLR.

Inclusion criteria

1. Patient has provided written, informed consent and is willing to participant; 2. Patient is prior to 6 months post ACLR following isolated rupture of the ACL; 3. Patient regularly participates in a Level 1 or Level 2 Activity level sports*; 4. Male and/or female patients of 14 years of age or greater. *Activity Levels are defined by those outlined by Hefti et al. 1993. Levels 1 and 2 will be sub-classified to whether the athlete competed at elite (professional) level, or non-elite level sport. - Level 1: Jumping, pivoting, hard cutting, football, soccer; o Level 1A: Competing at an elite, professional sporting level o Level 1B: Not competing in an elite, professional sporting level - Level 2: Heavy manual work, skiing, tennis; o Level 1A: Competing at an elite, professional sporting level o Level 1B: Not competing in an elite, professional sporting level - Level 3: Light manual work, jogging, running; - Level 4: Sedentary work (ADL) Reference: Hefti F, Muller W, Jakob RP, Staubli HU.
