Bottom Line

  • Subjective lameness outcomes for tibial plateau levelling osteotomy (TPLO) and tibial tuberosity advancement (TTA) appear to be similar, but, overall, TPLO may yield improved objective lameness outcomes with a lower risk of complications than TTA. However, prospective randomised trials are needed to answer this clinical question definitively.

  • Clinical scenario

    An orthopaedic surgeon has recently joined the practice you work in, and they routinely perform traditional tibial tuberosity advancement (TTA) when surgically treating dogs with cranial cruciate ligament (CCL) disease. You and the other vets in the practice have always performed tibial plateau levelling osteotomies (TPLO) on such cases. You wonder if a TTA yields similar postoperative outcomes to a TPLO in these patients.

    The question

    In [dogs with cranial cruciate ligament disease] does [performing a traditional tibial tuberosity advancement compared with a tibial plateau levelling osteotomy] result in [similar postoperative outcomes]?
