The pakicetid tibiae are long with a short tibial crest.

The other tibial section attaches directly to the tibia, anterior to the posteromedial tibial crest, 6 cm distal to the joint line.

This contrasts with previous methods of CrCL repair which aimed to provide stability to the joint by replacing the ligament either with a fascial graft within the joint, or using a prosthesis made of nylon placed externally from the lateral fabella to a hole drilled in the tibial crest.
