Despite the reports of good stability and subjective outcomes, revision surgery is probably a more important factor to consider. With the patellar tendon graft, there are low velocity concentric extensor deficits specific to 60- 95; with the hamstring graft, there are high velocity, eccentric flexor deficits specific to 60-95 Strengthening exercises need to be velocity, ROM and contraction specific to address these deficits. Avoid resisted knee extension to protect graft. [6,7] A study of surgeons in Italy showed a … Grafts can be done through two methods: the autograft and the allograft.
