Abstract

Background: Accurate donor-recipient matching of the femoral condyle radius of curvature (ROC) in osteochondral allograft (OCA) transplantation may aid in minimizing articular surface incongruities. Matching linear femorotibial dimensions, such as the femoral condyle anterior-posterior length (APL), femoral condyle width (lateral-medial length, LML), femoral hemicondyle width (HCW), and tibial plateau width (TPW), can provide similar results if they correlate well with ROC. This study investigates the relationship between femorotibial dimensions and ROC at the cartilage surface using magnetic resonance imaging (MRI).

Methods: Deidentified MRI images of 63 patients (35 men, 33 ± 10 years old, and 28 women, 27 ± 8 years old) were analyzed. Axial images were used for APL, LML, and TPW (TPW-Ax) measurements, while coronal images were used for HCW and TPW (TPW-Cor) measurements. Cartilage was segmented in true sagittal images at the medial femoral condyle (MFC) and lateral femoral condyle (LFC) to calculate their specific cartilage surface ROCs. Linear regression models were used to determine the relationship between the femorotibial dimensions and ROC.

Results: Cartilage ROC was significantly correlated with all the linear femorotibial dimensions at the MFC (P < 0.01, R² = 0.78, 0.69, 0.67, 0.59, and 0.37 for ROC correlations with APL, LML, TPW-Ax, TPW-Cor, and HCW, respectively), and the LFC (P < 0.01, R² = 0.81, 0.61, 0.56, 0.54, and 0.41 for ROC correlations with APL, LML, TPW-Ax, TPW-Cor, and HCW, respectively).

Conclusions: The APL was the most predictive femorotibial dimension of the cartilage surface ROC. Donor-recipient APL matching in OCA transplantation may provide a similar level of matching to that achievable by direct ROC measurements. The APL matching may help reduce cartilage incongruities, particularly for patients with large osteochondral lesions, in which the ROC measurement cannot be accurately determined.

期刊介绍： CARTILAGE publishes articles related to the musculoskeletal system with particular attention to cartilage repair, development, function, degeneration, transplantation, and rehabilitation. The journal is a forum for the exchange of ideas for the many types of researchers and clinicians involved in cartilage biology and repair. A primary objective of CARTILAGE is to foster the cross-fertilization of the findings between clinical and basic sciences throughout the various disciplines involved in cartilage repair. The journal publishes full length original manuscripts on all types of cartilage including articular, nasal, auricular, tracheal/bronchial, and intervertebral disc fibrocartilage. Manuscripts on clinical and laboratory research are welcome. Review articles, editorials, and letters are also encouraged. The ICRS envisages CARTILAGE as a forum for the exchange of knowledge among clinicians, scientists, patients, and researchers. The International Cartilage Repair Society (ICRS) is dedicated to promotion, encouragement, and distribution of fundamental and applied research of cartilage in order to permit a better knowledge of function and dysfunction of articular cartilage and its repair.
