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 (R(2) ) 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). R(2), 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.
前交叉韧带（ACL）撕裂是骨科患者常见的损伤，有许多不同的治疗方法，包括骨-髌腱-骨自体移植物（BPBA）ACL 重建。髌腱宽度已被报道为 BPBA 修复后恢复速度和成功率的预测指标。本研究报告了髌腱宽度与髌腱宽度之间关系的强度。本研究纳入了 20 例新鲜冷冻尸体。在髌腱中点记录髌腱和髌腱的测量值。采用 Pearson 相关和线性回归来确定髌腱宽度与髌腱宽度之间的关系。报告了双变量相关性，置信区间为 95%，决定系数（R²）。本研究使用了 20 具尸体，其中 12 名男性和 8 名女性，平均年龄 72 岁（标准差[SD] = 12；范围 44 至 87）。平均髌腱宽度为 49.24mm（SD = 4.11；范围 42.33mm-56.33mm），而平均髌腱宽度为 26.10mm（SD = 3.31；范围 18.33mm-33.33mm）。髌腱宽度与髌腱宽度之间的相关性为 0.67（95%置信区间为 0.45-0.81）。R²，即髌腱宽度解释的变异百分比，为 0.45。预测髌腱宽度（y）的回归方程得出的公式为 y = 0.536+-0.316×髌腱宽度。髌腱宽度与髌腱宽度之间存在中度相关性。我们的数据表明，这种相关性在较宽的髌腱中最强，与较小的髌腱相关性较弱。
