Postoperative Rehabilitation After Knee Arthroplasty: Anti-Gravity Treadmill

Not Applicable

Completed

• Conditions: Rehabilitation
• Interventions: Other: Rehabilitation with or without Anti-Gravity Treadmill

• Registration Number: NCT03904030
• Lead Sponsor: Orton Orthopaedic Hospital

Brief Summary

The aim of this study is to clarify the effectiveness and the usefulness of the anti-gravity treadmill in postoperative rehabilitation after knee arthroplasty. The investigators will compare anti-gravity treadmill rehabilitation and the traditional postoperative rehabilitation with instructions.

The investigators will assume that anti-gravity treadmill exercise after hospitalization will lead to the faster rehabilitation, better walking quality and balance management compared to traditional rehabilitation methods with instructions, where patient themselves do the exercises at home. Additionally, the investigators will assume that quality of life and physical activity will be more increased in the anti-gravity group than in the traditional rehabilitation.

Detailed Description

The aim of this study is to clarify the effectiveness and the usefulness of the anti-gravity treadmill in postoperative rehabilitation after knee arthroplasty. This issue is especially relevant because the number of knee arthroplasty patients is increasing. The rehabilitation of knee arthroplasty patients has also appeared to be more challenging than in the case of hip arthroplasty.

The investigators will compare anti-gravity treadmill rehabilitation and the traditional postoperative rehabilitation with instructions. The investigators will recruit the patients either in the anti-gravity group (n=27) or in the traditional rehabilitation (n=27) (randomized study design).

The investigators will assume that anti-gravity treadmill exercise after hospitalization will lead to the faster rehabilitation, better walking quality and balance management compared to the traditional rehabilitation.

Arm && Interventions

Group	Intervention	Description
Anti-Gravity Treadmill rehabilitation	Rehabilitation with or without Anti-Gravity Treadmill	Patients in the intervention group are participating to the Alter G exercises (n=27). The groups are randomized, so after patients have signed consent, an envelop will be opened and there can be seen in which groups patients will participate.
Traditional rehabilitation	Rehabilitation with or without Anti-Gravity Treadmill	Traditional exercises with instructions are given to the patients (n=27) (as a control group).

Primary Outcome Measures

Name	Time	Method
Perceived pain	12 months after operation	Visual analogue scale, (0 to 100, where 0 means no pain at all and 100 means the worst possible pain)
Walking ability	12 months after operation	6 minutes walking test will be used
Health-related quality of life	12 months	The RAND Health-Related Quality of Life Inventory, RAND 36-Item, will be used, RAND-36 includes: Physical functioning,10 questions; Role functioning/physical, 4 questions; Role functioning/emotional, 3 questions; Energy/fatique, 4 questions, Emotional well-being, 5 questions; Social functioning, 2 questions; Pain, 2 questions; General health, 5 questions; Health change, 1 question. All: 36 questions. Scale: 0 - 100
