Summary

The aim of this prospective randomized controlled study was to determine whether the timing of drain removal in relation to continuous passive motion (CPM) application influences postoperative residual hematoma formation following primary total knee arthroplasty (TKA). Our primary hypothesis was that removing the drain after initiating CPM would result in less residual hematoma, as CPM-induced intra-articular fluid and blood mobilization would be evacuated through the drain before its removal, thereby reducing postoperative fluid accumulation.

Conditions

  • Knee Osteoarthritis (Knee OA)
  • Total Knee Anthroplasty
  • Postoperative Hematoma

Interventions

PROCEDURE

Drain Removal Before CPM

Hemovac drain removal performed approximately 24 hours after primary TKA, immediately before a standardized 1-hour CPM session (0-90°). All other surgical, perioperative, and rehabilitation protocols are identical across study arms.

PROCEDURE

Drain Removal After CPM

A standardized 1-hour CPM session at 0-90° is administered approximately 24 hours after primary TKA. The hemovac drain is removed immediately after completion of the CPM session. All other surgical, perioperative, and rehabilitation protocols are identical across study arms.
