Patellar Tendon
The patellar tendon connects the patella (kneecap) to the tibia (shin). Generally the graft is taken from the injured knee, but in some circumstances (such as a second operation) the other knee may be used. The middle third of the tendon is used, with bone fragments on each end removed. The graft is then threaded through holes drilled in the tibia and femur, and finally screwed into place.
The graft is slightly larger than a hamstring graft, however graft size is not a determinant of outcome. The most important factor in determining the outcome is correct graft placement.
The disadvantages include: 1. more wound pain , 2. more prominent scar as compared to hamstring tendon operation , 3. risk of fracture of patella during harvesting of this graft resulting in significant complication , 4. increased risk of tendonitis.
