Effect of Preoperative Kinesiophobia on Clinical Success in Patients Undergoing Arthroscopic Surgery for Meniscal Tears

Meniscal tears are among the most common knee injuries encountered in orthopedic practice and represent a major cause of knee pain, mechanical symptoms, and functional impairment. Although conservative treatment may be effective in selected patients, arthroscopic surgery remains a widely performed procedure for individuals with persistent symptoms or mechanical dysfunction. Despite advances in surgical techniques and standardized rehabilitation protocols, postoperative recovery varies considerably among patients with similar structural pathology, suggesting that factors beyond the anatomical lesion may influence clinical outcomes.

Psychological factors have increasingly been recognized as important determinants of recovery after musculoskeletal injuries and orthopedic surgery. Among these, kinesiophobia, defined as an excessive and debilitating fear of movement resulting from pain or the anticipation of reinjury, may negatively affect rehabilitation adherence, physical activity, muscle performance, and overall functional recovery. Patients with high levels of kinesiophobia may avoid movement, resulting in delayed restoration of knee function and persistent disability. However, evidence specifically evaluating the influence of preoperative kinesiophobia on outcomes following arthroscopic meniscal surgery remains limited.

The present study is designed as a prospective, single-center, observational cohort study to investigate the effect of preoperative kinesiophobia on postoperative clinical success in patients undergoing arthroscopic surgery for meniscal tears. Adult patients aged 18 to 65 years with a diagnosis of a meniscal tear confirmed by clinical examination and magnetic resonance imaging (MRI) and scheduled for arthroscopic surgery will be consecutively enrolled.

Baseline assessments will include demographic characteristics, body mass index, symptom duration, affected side, meniscal tear localization, and the type of arthroscopic procedure performed. Pain intensity will be evaluated using the Visual Analog Scale (VAS), functional status will be assessed using the Lysholm Knee Score, and fear of movement will be measured using the Tampa Scale for Kinesiophobia (TSK). All outcome measures will be recorded preoperatively and at the postoperative third month, providing a standardized assessment of changes in pain, function, and kinesiophobia over the early recovery period.

Participants will be categorized according to their preoperative kinesiophobia levels, and postoperative clinical outcomes will be compared between groups. In addition, correlation analyses will be performed to determine the relationship between preoperative kinesiophobia and postoperative pain and functional recovery. Appropriate statistical methods will be used to evaluate between-group differences and associations, with statistical significance defined as p < 0.05.
