Intraosseous schwannoma of D12 thoracic vertebra: diagnosis and surgical management with 5-year follow-up.

Does the Lachman testing method affect the reliability of the International Knee Documentation Committee (IKDC) Form?

The aim of this study was to evaluate the effect of manual and instrumented means of Lachman testing on the reliability of the IKDC form. A single observer assessed 102 patients with ACL deficiency (direct comparison group). Another observer assessed 35 of these patients (inter-observer group) and the initial observer re-assessed 47 patients (test-retest group).
