The utility of clinical measures for the diagnosis of achilles tendon injuries: a systematic review with meta-analysis.

Objective: To summarize and evaluate the current diagnostic accuracy of clinical measures used to diagnose Achilles tendon injuries. Data Sources: A literature search of MEDLINE, CINAHL, and EMBASE databases was conducted with key words related to diagnostic accuracy and Achilles tendon injuries. Study Selection: Original research articles investigating Achilles tendon injuries against an acceptable reference standard were included. Data Extraction: Three studies met the inclusion criteria. Quality assessment was conducted using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. DerSimonian-Laird random-effects models were used to pool sensitivity (SN), specificity (SP), and diagnostic odds ratios with their 95% confidence intervals (CIs). Data Synthesis: The SN and negative likelihood ratio (−LR) values for Achilles tendon rupture measures ranged from 0.73 (95% CI = 0.65, 0.81) and 0.30 (95% CI = 0.23, 0.40) to 0.96 (95% CI = 0.93, 0.99) and 0.04 (95% CI = 0.02, 0.10), respectively, whereas SP...
