Summary

Background:

An estimated 4000 Anterior Cruciate Ligament Injuries (ACL) occur annually in Norway (Granan et al., 2004). 1630 primary ACL reconstructions were performed in Norway in 2008 (Norwegian Arthroplasty Register, 2009). Approximately 120 of these ACL reconstructions were performed at Haraldsplass Deaconess Hospital.

Physical therapists at our hospital are responsible for postoperative outpatient controls of patients with a reconstructed anterior cruciate ligament. A clinical observation is that stair walking (especially downstairs) may be problematic up to 6 months after ACL reconstruction. One reason may be that the quadriceps muscle is unable to control the knee when the subject is walking downstairs, and that the knee is perceived to be unstable. Other contributing factors may be pain and swelling.

It is of interest to know which pre and post operative factors can predict measured and patient reported function 6 months after ACL reconstruction. Previous research shows that predictive factors for clinical outcome after ACL reconstruction are anterior knee pain (Heijne et al., 2009), preoperative electromyography, early postoperative strength (McHugh et al., 2002), preoperative quadriceps muscle strength deficits, meniscus injury and pain (Eitzen et al., 2009), obesity, smoking and serious chondrosis (Kowalchuk et al., 2009).

Purpose:

1. To analyse which pre and post operative factors can predict measured and patient reported function 6 months after Anterior Cruciate Ligament reconstruction.
2. To investigate if there is an asymmetry in step time between the affected and unaffected leg during down stairs walking, and if degree of asymmetry decreases during a 6 months period post operatively. Further we want to compare step time asymmetry with other established outcome measures to investigate sensitivity to change over the observation period and also compare the patient group in this study with a control group of healthy subjects to see if asymmetry in the patient group after 6 months is still higher than in healthy subjects.
