“…This finding is in accordance with previous studies 12,13,17 in which similar functional outcomes were seen in patients with higher BMI scores after ACLR. Overall, we observed that a higher BMI was associated with lower subjective IKDC scores at 1 and 2 months, but this effect did not necessarily occur when the traditional obesity threshold was used as a cutoff point (nonobese ¼ BMI ,30, obese ¼ BMI !30).…”

Context: Substantial research has been conducted on anterior cruciate ligament reconstruction (ACLR) to evaluate patient outcomes. However, little attention has been given to outcomes during the early phase of recovery and how early deficits affect both short-and long-term outcomes.Objective: To identify relationships between demographic (age, sex, and body mass index [BMI]) and intraoperative (isolated ACLR versus primary ACLR þ secondary procedures), and postoperative (range-of-motion [ROM] and peak isometric knee-extension force [PIF]) variables during the first 2 months after ACLR using self-reported outcomes.Design: Cohort study. Results: Significant relationships were identified between !12-month IKDC scores and the 1-month (Pearson correlation, r ¼ 0.283, r 2 ¼ 0.08; P ¼ .025) and 2-month (r ¼ 0.301, r 2 ¼ 0.09; P ¼ .017) IKDC scores. After controlling for other variables, we found that the PIF ratio measures at 1 and 2 months were positively associated with 1-and 2-month IKDC scores (P , .001) and BMI was negatively associated with both 1-and 2-month IKDC scores (P , .05). One-month IKDC scores were related to the 1-month difference in knee-flexion ROM (P ¼ .04).Conclusions: The IKDC scores during the first 2 months were positively correlated with patients' perceptions of function on long-term IKDC scores. It also appears that improvements in lower extremity strength and flexion ROM deficits were positively associated with short-term IKDC scores. Higher BMI was negatively associated with patients' perceptions of function on short-term IKDC scores.Key Words: force output, knee, motion, rehabilitation, International Knee Documentation Committee Key PointsAfter anterior cruciate ligament reconstruction, patients' subjective International Knee Documentation Committee (IKDC) scores at both 1-and 2-month follow-ups had fair but significantly positive associations with the !12-month IKDC score. The ratio of surgical-to nonsurgical-limb measures of peak isometric knee-extension force at 1 and 2 months was positively associated with 1-and 2-month IKDC scores. The difference in flexion range of motion between the surgical and nonsurgical limbs had a significant positive relationship with 1-month IKDC score. Body mass index had a significant negative association with both 1-and 2-month IKDC scores. No significant relationships were noted between demographic, intraoperative, or postoperative variables during the first 2 months and IKDC scores at !12 months after anterior cruciate ligament reconstruction.

“…The other KOOS subscale scores reported by ACL-deficient groups were similar to those reported by the general Swedish population (Frobell et al, 2008). In contrast, all ACL-deficient groups reported more knee pain and worse function in sport and recreation compared to amateur soccer players and military …”

Long-term quality of life following anterior cruciate ligament injury and reconstruction

The anterior cruciate ligament (ACL) serves to stabilise the knee complex and prevent intraarticular knee structures from sustaining damage during multiaxial, high impact movement. An ACL rupture most commonly occurs in adolescents and young adults taking part in competitive sports and causes substantial disruption to the knee joint. Anterior cruciate ligament reconstruction (ACLR) is the most common treatment offered to ACL-ruptured individuals worldwide. Individuals undergoing this surgery often have high expectations that rarely match surgical outcomes. Return to sport rates are low, re-injury fears are widespread and many individuals develop knee osteoarthritis within ten years of ACLR. This mismatch between expectations and actual outcomes has great potential to impact longer-term quality of life (QOL). The primary aims of this thesis were to: (i) generate a detailed picture of longer-term QOL following ACLR, and (ii) identify factors related to longer-term QOL in people with knee pain, symptoms or functional limitations following ACLR.The first study in this thesis is a systematic review that revealed impaired knee-related QOL at 5 to 20 years after ACLR. However, it became evident that research into factors impacting upon QOL in this population was scarce. The systematic review found that having a subsequent knee injury, an additional knee surgery after ACLR, and developing severe radiographic osteoarthritis were associated with worse QOL outcomes. The second study in this thesis is a systematic review that investigated QOL more than five years after ACL rupture in individuals who remained ACL-deficient (did not undergo ACLR) and compared QOL between ACLdeficient and ACL-reconstructed groups. This systematic review found that ACL-deficient individuals reported comparable QOL outcomes to those who underwent ACLR 5 to 25 years previously. All studies that reported QOL after ACLR included asymptomatic participants without knee difficulties, which may underestimate the degree of QOL impairment experienced by people with ongoing knee difficulties.The third study in this thesis used a cross-sectional design to describe QOL outcomes in 162 individuals with knee pain, symptoms or functional limitations 5 to 20 years following ACLR.It showed that individuals who did not return to sport after ACLR reported poorer knee-related and health-related QOL, compared to people who returned to pre-injury levels of sport. Higher body mass index (BMI) and subsequent surgery were also related to worse QOL after ACLR.This was the first study to show that return to sport was associated with QOL impairment more than five years after ACLR. However, quantitative assessment of QOL may overlook important considerations with regard to an individual's life priorities, expectations, values and concerns.To provide a detailed understanding of QOL following ACLR, qualitative interviews were performed with 17 individuals with knee difficulties 5 to 20 years following ACLR. This was the first qualitative study to explore QOL following...
