Introduction: Anterior knee pain (AKP) is a very common complication after anterior cruciate ligament reconstruction (ACLR). Although AKP is a well-known complication, pain after ACLR has never been specifically classified or localized. The aim of this study was to classify and localize postoperative pain after arthroscopic ACLR and to investigate its influence on the subjective functional outcome and quality of life, taking the psychological state of the patients into account. Material and Methods: This is a prospective observational study of 103 patients (mean age 32 years) undergoing arthroscopic ACLR with a mean follow-up of 3.1 years. All subjects underwent surgery at the University hospital of Graz (Austria) between March 2010 and August 2019. The data were collected once postoperatively via a self-designed electronic Case Report Form (eCRF) at cross-section. Results: Knee pain occurred mainly in the medial knee joint (61.2%) and in the popliteal fossa (43.7%). Medial knee pain was more common in men (67.1% vs. 44.1%). Popliteal knee pain was more common in men (51.3% vs. 22.2%) and younger patients. Patients with medial knee pain and popliteal fossa pain had significantly worse subjective functional outcome scores (IKDC, TAS, Lysholm score), lower SF-36 scores and more kinesiophobia compared to the rest of the study population. Negative correlations between IKDC and Lysholm score with the NRS scale were not mediated by psychological parameters (FESS, TSK, PCS). Discussion: Pain sensations after arthroscopic ACLR are a chronic condition in the medial knee joint and the popliteal fossa. Even with low pain intensity, these pain sensations have a significant impact on function and quality of life. The origin and prevalence of these pain sensations should be further addressed in future studies to further improve the quality of arthroscopic ACLR.
