Summary

Early flexion after total knee arthroplasty significantly reduces hospital stay and costs while improving range of motion. This approach offers a cost-effective alternative to continuous passive motion for knee replacement patients.

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Total knee arthroplasty (TKA) is a common procedure for end-stage knee arthritis.
  • Optimizing post-operative recovery, including range of motion and hospital resource utilization, remains a key focus in TKA outcomes.

Purpose of the Study:

  • To evaluate the impact of early maximum flexion protocols on patient outcomes following primary cementless total knee arthroplasty.
  • To compare the efficacy of early flexion versus standard care in terms of hospital stay, costs, and functional recovery.

Main Methods:

  • A prospective study involving 100 patients undergoing cementless meniscal-bearing TKA by a single surgeon.
  • Patients were divided into two groups: a retrospective control group (Group I, n=50) and a prospective early flexion group (Group II, n=50).
  • Data collected included length of stay, hospital costs, and range of motion at one year post-surgery.

Main Results:

  • The early flexion group (Group II) demonstrated a significantly decreased length of hospital stay compared to the control group (Group I).
  • Hospital costs were reduced in the early flexion group.
  • Patients in the early flexion group achieved a greater range of motion at the one-year follow-up.

Conclusions:

  • Implementing an early maximum flexion protocol after primary cementless total knee arthroplasty can lead to significant reductions in hospital length of stay and associated costs.
  • This early flexion approach also enhances the range of motion at one year, suggesting improved functional recovery.
  • Early flexion presents a viable and cost-effective alternative to continuous passive motion therapy in the post-TKA recovery phase, aligning with healthcare cost-reduction initiatives.
