Indications for Tibial Stem Use in Primary Total Knee Arthroplasty

Primary Indications for Tibial Stem Use

• The American Academy of Orthopaedic Surgeons provides strong evidence supporting no difference in outcomes between cemented and non-cemented tibial component fixation in routine primary TKA, with a recommendation to avoid using tibial stems in primary TKA when bone is healthy with good structural properties and normal anatomy 1, 2

Common Pitfalls to Avoid

• The American Academy of Orthopaedic Surgeons guideline provides strong evidence to avoid using long stems (>100mm) in primary TKA unless dealing with extensive bone defects, and to avoid stemless components in patients with known osteoporosis or severe obesity, as inadequate initial fixation may lead to early loosening 1, 2
