Brief Summary

Swelling is a common problem after knee arthroplasty often leading to delayed wound healing, lasting functional impairment and hematoma.

Due to this complications, sometimes the risk for deep venous thrombosis is raised. This study investigates a new self adjustable device to reduce swelling more effective postoperatively. The investigators compare the new device to the current general practice by using a standard class 1 elastic stocking

Detailed Description

Purpose Pain, swelling and inflammation are expected during early recovery from total knee arthroplasty (TKA). Compression therapy is a frequently used modality in the direct post operative treatment, but there is a great variety in the use of materials, the way and time frame of application. The most common goals of the compression therapy are prevention and reduction of the swelling. At the same time the literature is not consistent about the use and effects of compression therapy other than for prevention of trombo-embolic processes The state of the art care concepts for patients undergoing a total knee arthroplasty embraces the concept of "fast track" (Kehlet et al) with important parts as early mobilisation and optimal analgesics. In the investigators hospital this concept has already been implemented.

During the stay in the hospital the challenge is to give adequate compression therapy to prevent and reduce swelling and enhance woundhealing. At the same time it is essential to optimise ambulation of the patient and the possibilities to exercise.

The current protocol in the investigators hospital consists of 24 hours compression therapy with "Elastomull Haft ®", an elastic bandage for the knee region, combined with a Comprinet stocking (BSM Medical®) for anti thrombotic purposis. The anti thrombosis stocking is worn for a period of 6 weeks.

The compression is combined with the use of the Continious Passive Motion device for 4 hours post operatively (2 hours immobilisation in a position of 90 degrees flexion, followed by 2 hours hours of passive motion in a range of 60-90 degrees flexion). Four hours post operatively the patient is ambulatend and the physical therapy starts.

The investigators wonder if this is the optimal way of post-operative care. Swelling of the knee and the whole leg can remain a problem in the first 6 weeks of recovery which inhibits rehabilitation. Sometimes delayed woundhealing will occur and patients may complain of more durable pain which make analgesics necessary.

Prolonging adequate compression could improve the post-operative course and support the total rehabilitation process.

The "Juxta Reduction Kit (by Medi) ®" , applied for the knee could be an adequate solution to replace the current protocol of compression therapy.

The "Juxta Reduction Kit ®" is a non-elastic compression device which can be tailored (by cutting it to the correct size) to the circumference of the leg prior to the operation. Direct post operatively the compression device can be adjusted by the staff and in the following days patients are enabled to adjust the device by themselves by using the Velcro ties to loosen or fasten it.

The device is suitable in early mobilisation and gives the patient tools for selfmanagement of the compression by using the Velcro flaps. The material doesn't restrict the range of motion and so the possibility to ambulate and to exercise as advised in the fast track concept is optimised.

In this study the patients will use the compression device for a period of six weeks in combination with an anti thrombosis stocking (Struva class 2) Outcome parameters will be measured in a scheduled way, described in scheme 1.

Study Groups

current compression stocking Comprinet®

Immediately post operatively 24 hours compression therapy starts with "Elastomull Haft ®", an elastic bandage, combined with a Comprinet stocking (BSM Medical®) for anti thrombotic purposes. The anti thrombosis stocking is worn 6 weeks post operatively. After 4 hours the patient is ambulated and the physical therapy starts.

Juxta Reduction Kit ® Immediately post operative compression starts with the Juxta Reduction Kit® for the knee region, combined with an anti thrombosis stocking (Struva 2, for prevention of trombo-embolism). Both the stocking and the Juxtra Pro are used for six weeks. After 4 hours the patient ambulated and the physical therapy starts.

For the first 24 hours and longer if necessary (depending on the skills of the patient) Juxta experienced staff will apply the device and the fit and the use of the device will be checked.

In the second phase between approximately 24 hours and 6 weeks patients may adjust the Juxta-pro according to their needs and comfort by themselves.
