Physiotherapy management of knee osteoarthritis in Nigeria—A survey of self-reported treatment preferences

Abstract

Background

knee osteoarthritis (OA) is a prevalent condition. Little is known about whether treatments provided by physiotherapists to patients with knee OA in Nigeria follow recommended clinical practice guidelines.

Objective

The aims of this study were to investigate Nigerian physiotherapists' treatment preferences for knee osteoarthritis (OA) and to evaluate if their preferences were in line with contemporary clinical practice guidelines and recommendations.

Methods

A cross-sectional survey of 267 physiotherapists from various health institutions in Nigeria were surveyed, using a structured questionnaire incorporating a clinical vignette on knee OA.

Results

Based on the clinical vignette, the majority of the respondents (68.2%) recommended review of x-rays as part of the diagnostic process for knee OA. Thermotherapy was the most utilized modality (86.1%), followed by therapeutic exercise (81.3%). Only 11.1% of the physiotherapists used therapeutic exercise alone. Manual therapy in conjunction with other modalities was the choice for 18% of the physiotherapists. Only 49.1% of the physiotherapists reported including advice on weight control and up to 39% reported bed rest as part of the treatment approach.

Conclusion

There was a poor consensus among the physiotherapists in Nigeria on how knee OA is managed compared with contemporary clinical guidelines and recommendations which emphasized application of core modalities, such as therapeutic exercises, patients' education, and weight control over passive modalities. Some areas of practice are in line with contemporary guidelines, while some were in conflict with evidence-based practice.
