Relationship between self-reported and functional outcomes of physically active patients 6 and 12 months after anterior cruciate ligament reconstruction surgery

Abstract

Introduction. ACL reconstruction aims to get rid of functional instability, thereby decreasing the incidence of subsequent injuries (1). Return to pre-injury activity level involves physical factors and psychological factors (2). “Function” is an outcome important to patient satisfaction after ACL reconstruction. However, there are various tools that can be used to measure function, and measurements used to determine return to play may be different than those ultimately used to determine surgical outcome (3). Research aim. To evaluate patients' subjective opinion about operated knee function and their relationship with HOP tests. Research methods and organization. Seventy patients, 44 males (age 25.44 ± 8.14 years, height 186.31 ± 9.84 cm, weight 87.22 ± 12.51 kg, BMI 25.03 ± 3.14) and 26 females (age 24.10 ± 5.87 years, height 170.85 ± 10.43 cm, weight 63.67 ± 9.77 kg, BMI 21.74 ± 2.02), who had undergone an ACL reconstruction were tested. The operated patients were tested 6 or 12 months after surgery. They underwent the 4 single leg (hop for distance, crossover hop for distance, triple hop for distance and 6 m timed hop) HOP tests (4) and completed the IKDC 2000. The best trial for each leg in each test was used for data analysis. According to the HOP tests limb symmetry index (LSI) results, patients were divided into two groups: first group LSI ≥ 90% and second group LSI < 90%. Then groups’ results were compared with each other. Statistical analysis was performed with SPSS 22 Software. The degree of statistical significance was set at p < 0.05. Differences were assessed using Mann-Whitney test. A Pearson‘s correlation was run to determine the relationship between HOP tests and IKDC 2000 questionnaire. LSI was calculated as the hop distance of the healthy leg divided by the hop distance of the operated leg multiplied by 100. Results are presented in means ± standard deviation. Results. The[...].
