Summary

High tibial osteotomy (HTO) can alter posterior tibial inclination, leading to a drop in patellar height. Preserving tibial inclination during HTO may prevent patellar infera and improve patellofemoral mechanics.

Area of Science:

  • Orthopedic surgery
  • Biomechanics
  • Knee joint anatomy

Background:

  • High tibial osteotomy (HTO) is a common surgical procedure for knee osteoarthritis.
  • Alterations in tibial plateau geometry can affect patellofemoral joint mechanics.
  • The relationship between proximal tibial inclination changes and patellar height post-HTO requires further elucidation.

Purpose of the Study:

  • To investigate the correlation between changes in proximal tibial inclination and subsequent patellar height after high tibial osteotomy.
  • To assess the incidence of posterior tibial inclination loss and patellar height reduction following HTO.

Main Methods:

  • Retrospective evaluation of 46 knees in 41 patients who underwent high tibial osteotomy.
  • Measurement of posterior tibial inclination and patellar height using the Insall-Salvati ratio.

Related Experiment Videos

  • Statistical analysis to determine the association between tibial inclination alteration and patellar height changes.

    • Main Results:

    • 61% of knees demonstrated a loss of ≥5 degrees of posterior tibial inclination post-HTO.
    • 54% of knees exhibited a relative patellar height reduction of >10% (Insall-Salvati ratio).
    • A statistically significant association was found between the loss of posterior tibial inclination and subsequent patellar height reduction.

    Conclusions:

    • Loss of posterior tibial inclination following HTO is common and significantly associated with decreased patellar height.
    • Careful preservation of posterior tibial inclination during HTO is crucial.
    • Maintaining tibial inclination may help prevent patellar infera and adverse changes in patellofemoral mechanics.
