Unlike the medical literature that focuses narrowly on rehabilitation, the study research shows that standardized rehabilitation programs are interpreted, experienced, and executed differently by participants. The authors argue that these differences are related to preinjury understandings of self and body, previous sport movement experiences, and differing faith in the physiotherapist and rehabilitation center's expertise. It is very likely that understanding how patients think about their embodied selves and their differing interpretations and executions of rehabilitation programs can contribute to a more useful understanding of different functionality and more effective rehabilitation program. Keywordsphenomenology, rehabilitation, experience, ACL injury, qualitative interviews, functional ability Introduction and BackgroundMedical research remains ambiguous about why persons who sustain injuries to their anterior cruciate ligament (ACL), the ligament that stabilizes the knee, experience different postrehabilitation stabilization abilities. Most of the literature on ACL rehabilitation focuses on athletes since athletes are most likely to sustain ACL injuries; thus, studies of knee rehabilitation is particularly important for sport studies. In their research on ACL injury rehabilitation, Noyes, Mooar, Matthews, and Butler (1983) and Rudolph et al. (Rudolph, Axe, Buchanan, Scholz, & Snyder-Mackler, 2001) use the concept "functional outcome" and claim that postrehabilitation functional outcome is uncertain and unpredictable. Fitzgerald et al. (Fitzgerald, Axe, & Snyder-Mackler, 2000) and Rudolf et al. (Rudolph, Eastlak, Axe, & Snyder-Mackler, 1998) call for more research into physiological and biomechanical issues in an effort to help explain functional differences. Notably, despite their reliance on these terms, the researchers do not clarify the definitions of "functional outcome" or "function." Research using biomechanical measurements of the hip, ankle, and knee joint, and electromyographical measurements of the musculature in the lower extremities shows that, biomechanically speak...
