Summary

Preoperative function, walking ability, and comorbidities significantly predict functional outcomes after total knee arthroplasty (TKA). Patients with lower baseline function may need more intensive physical therapy post-TKA.

Area of Science:

  • Orthopedics
  • Rehabilitation Medicine
  • Health Services Research

Background:

  • Decreasing hospital stays after total knee arthroplasty (TKA) impact rehabilitation planning.
  • Identifying modifiable preoperative determinants of functional status is crucial for effective physical therapy discharge planning.

Purpose of the Study:

  • To identify preoperative factors that predict functional status 6 months after primary total knee arthroplasty (TKA).

Main Methods:

  • A prospective cohort study of 276 patients undergoing primary TKA in Canada.
  • Data collected preoperatively and 6 months postoperatively.
  • Function assessed using the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the SF-36 Health Survey.

Main Results:

Related Experiment Videos

  • At 6 months post-TKA, average WOMAC physical function was 70.5 and SF-36 physical function was 44.8.
  • Preoperative function, use of walking devices, walking distance, and comorbid conditions predicted 6-month functional outcomes (WOMAC R2=.20; SF-36 R2=.27).

Conclusions:

  • Lower preoperative functional status is associated with poorer 6-month outcomes after TKA.
  • Patients with lower preoperative function may necessitate more intensive physical therapy interventions to achieve optimal results.
