The medial patellofemoral ligament originates an average of 7 mm distal to the medial distal femoral physis, according to a systematic review performed by researchers at the department of orthopedic surgery at Stanford University.
The researchers analyzed seven articles (298 femurs) that investigated the anatomy of the medial patellofemoral ligament (MPFL) in relation to the medial distal femoral physis in patients with a mean age of 11.7 years, according to the abstract of the review.
Individual study results showed the MPFL originated distal to the medial distal femoral physis in 92.8% of patients, with a range from 3.7 mm proximal to the physis to 10 mm distal to the physis (mean distance of 6.9 mm), according to the abstract.
Researchers qualified that the 7 mm average proximal-to-distal distance is variable in the literature and could differ dependent on study, patient age and sex, they wrote in the abstract.
Bias risk was categorized using the anatomical quality assessment tool, which ultimately determined a low risk of bias, according the abstract. – by Max R. Wursta
