Does an Elastic Compression Bandage Provide Any Benefit After Primary TKA?

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Compression bandages are commonly used post-total knee arthroplasty (TKA) to manage swelling.
• The clinical effectiveness of these bandages after TKA remains incompletely understood.

Purpose of the Study:

• To evaluate the association between compression bandage use and reduced leg swelling after TKA.
• To assess the impact of compression bandages on range of motion (ROM), pain scores (VAS), and wound complications post-TKA.

Main Methods:

• A prospective, randomized controlled trial involving 51 patients undergoing bilateral TKA.
• Patients received either a compression bandage or no bandage on one limb for comparison.
• Measurements included limb circumference, ROM, and VAS pain scores at multiple postoperative time points.

Main Results:

• No significant differences were observed in leg swelling (thigh, knee, shin) between the compression bandage and control groups.
• Flexion and extension ROM showed no significant improvement with compression bandage use.
• Postoperative pain scores were slightly higher on POD 1 and POD 2 in the compression bandage group, with no significant difference at POD 28.

Conclusions:

• Compression bandage application after TKA did not demonstrate clinical benefits regarding leg swelling, ROM, or pain.
• The study suggests that compression bandages neither benefit nor harm patients undergoing TKA.
• Routine use of compression dressings for primary TKA is no longer recommended based on these findings.
