Self-efficacy is positively associated with adherence behaviours and rehabilitation outcomes following Anterior Cruciate Ligament (ACL) reconstruction. An internet resource can be an effective way to provide information, goal setting, patient monitoring and hence support overall self-management.This study examined the feasibility of a three month 'internet-based intervention' (mobile-oriented site) to enhance recovery for patients following ACL reconstruction. The potential effect of the internet-based intervention on knee pain, function, self-efficacy and fear of pain were also assessed.This was a pilot randomised controlled trial (RCT) with pre and post intervention design (assessments at one week and three months following ACL reconstruction) comparing: (1) a control group and (2) an intervention group (internet-based intervention). A set of qualitative and quantitative assessments were included to evaluate potential improvements in self-efficacy, pain and function and perception of the internet intervention.Seventeen participants were available for analysis (n = 10 intervention and n = 7 control group). Participants reported the internet-based intervention to be a useful tool for information, reminder and reinforcement for performing their exercise rehabilitation with 30.3% (±35.3%) adherence to the internet-based intervention. No differences were observed between the groups over time on the outcome questionnaires (p 0.05). Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12616001379404.

Objectives Patients with patellofemoral pain syndrome (PFPS) often demonstrate a collapse of the knee in the medial direction during a one-leg squat. This study investigated the medial displacement magnitude of the knee during a one-leg squat test in females with PFPS. Design The study design was a cross sectional comparative investigation. Participants Thirteen healthy females and 12 females with PFPS. Main measures Participants were tested during a one-leg squat test using a single camera. The thigh segment alignment in the frontal plane was measured by the angle projected between the long axis of the thigh and the foot (femoral frontal angle) and the horizontal deviation (femoral deviation) of the distal thigh relative to the foot. Results A one-way ANOVA showed that the femoral frontal angle was significantly larger ( p =0.019) for the PFPS group with no significant differences for the femoral deviation ( p =0.288). Both measurements showed good trial-to-trial reliability while the femoral frontal angle showed good test–retest reliability. Conclusion The increased femoral frontal angle magnitude during the one-leg squat demonstrates that the one-leg squat may be a useful clinical tool for the evaluation process of PFPS.
