A 68-year-old male returns to the reconstruction clinic 1 year out from left total knee arthroplasty. The patient was doing well at his 2 and 6-week follow-up appointments, however, has not returned to the clinic since. The patient reports approximately 6 months ago he suffered a fall and has had decreased knee extension since that time. Due to concern about contracting a viral illness, he did not want to return to the clinic.

When comparing extensor mechanism reconstruction with mesh or allograft, which of the following statements is true?
