Anterior cruciate ligament (ACL) rupture is a common injury among orthopaedic patients with many different treatment modalities including bone-patella-bone autograft (BPBA) ACL reconstruction. Patella tendon width has been reported to be a predictor of recovery speed and success following BPBA repair. This study reports on the strength of the relationship between patella width and patella tendon width. Twenty fresh frozen cadavers were included in the study. Patella and patellar tendon measurements were recorded at the midpoint of the patellar tendon. Pearson correlation and linear regression were used to determine the relationship between patella width and patellar tendon width. Bivariate correlations with 95% confidence intervals and coefficients of determination (R2) are reported. The study used 20 cadavers, 12 men and 8 women with a mean age of 72 (standard deviation [SD] = 12; range = 44 to 87). The mean patella width was 49.24mm (SD = 4.11; range 42.33mm–56.33mm) while the mean patellar tendon width was 26.10mm (SD = 3.31; range 18.33mm–33.33mm). The correlation between patella width and patellar tendon width was 0.67 (95% confidence interval = 0.45 − 0.81). R2, the percent of variance in patellar tendon width accounted for by patella width, was 0.45. The regression equation for predicting patellar tendon width (y) yielded a formula of y = 0.536 + −0.316 × patella width. A moderate correlation exists between patella width and patellar tendon width. Our data suggests that this correlation is strongest with wider patellas and is more loosely associated with smaller patellas. Clin. Anat. 25:398–400, 2012. © 2011 Wiley Periodicals, Inc.
