Is closed suction drainage effective in early recovery of hip joint function? Comparative evaluation in one-stage bilateral total hip arthroplasty.

One-stage primary bilateral cementless total hip arthroplasty with unilateral closed suction drainage (CSD) was prospectively performed for 51 patients (102 hips), and local effects of CSD were quantitatively evaluated. Postoperatively, pain scores evaluated by visual analog scale and periwound temperatures measured by thermography were lower in the CSD side than the non-CSD side. CT measurements also showed that postoperative cross-sectional area of the thigh was smaller in the CSD side. Active straight leg raising and weight bearing were more accelerated in the CSD side., showing earlier recovery of hip joint function. CSD for hip arthroplasty has an advantage in reducing postoperative local inflammation and be recommended from the viewpoint of postoperative pain relief and early recovery of hip joint function.
