Hemoglobin levels before and after total knee replacement surgery impact rehabilitation outcomes. Lower hemoglobin and higher age correlate with longer recovery, but motor function can still improve.

Area of Science:

  • Orthopedics
  • Rehabilitation Medicine
  • Hematology

Background:

  • Total knee arthroplasty (TKA) is a common procedure for degenerative joint disease.
  • Patient rehabilitation outcomes after TKA are influenced by various factors.
  • Hemoglobin levels, age, and comorbidities are potential predictors of rehabilitation success.

Purpose of the Study:

  • To investigate the association between preoperative and postoperative hemoglobin levels and rehabilitation outcomes.
  • To explore the relationship between hemoglobin levels, patient age, and selected comorbidities.
  • To identify factors influencing motor function recovery and length of stay post-TKA.

Main Methods:

  • Retrospective chart review of 49 patients undergoing TKA.
  • Analysis of rehabilitation admission and discharge motor Functional Independence Measure (FIM) scores.

  • Assessment of motor FIM gain and rehabilitation length of stay.

    • Main Results:

    • Higher preoperative hemoglobin correlated with higher admission motor FIM scores but lower motor FIM gains.
    • Elevated hemoglobin at rehabilitation admission was linked to better admission scores and shorter stays.
    • Diabetes was associated with lower preoperative hemoglobin; hypertension with longer stays. Older patients had poorer scores and longer stays.

    Conclusions:

    • Motor function improvement is achievable post-TKA irrespective of hemoglobin levels or fluctuations.
    • Patients with lower hemoglobin, lower admission motor FIM scores, advanced age, or hypertension may require extended rehabilitation.
    • Optimizing hemoglobin levels and managing comorbidities could potentially enhance TKA recovery.
