Clinical Trial Summary

The primary aim is to investigate the frequency and severity of neuropathic pain and its association with night pain in patients with knee osteoarthritis. For this purpose a progressive longitudinal study design was planned. The secondary aim is to investigate the relationship between night pain and neuropathic pain and sleep quality.

Description:

Osteoarthritis (OA) is the most common form of arthritis in the world. Classically, OA presents with joint pain and loss of function; however, the disease is clinically very variable and can present merely as an asymptomatic incidental finding to a devastating and permanently disabling disorder. The severity of knee pain caused by osteoarthritis, often does not correlate with the degree of degenerative changes in the joint. In patients reporting night pain, this may be related to inflammation, but in the absence of clinical and laboratory findings of inflammation, it is not possible to explain night pain only by the degree of joint damage. The existence of a relationship between night pain and neuropathic pain may be a guide in looking for neuropathic pain in patients who have night pain and experience this pain severely and thus for planning an appropriate treatment for the patient. Patients with stage 2-4 knee OA will be evaluated in terms of demographic variables and outcome measurement parameters specified in the case report form. The relationship between neuropathic pain scores and knee pain severity will be sought. It will be studied whether there is a difference in outcome measurement parameters between those with neuropathic pain and those without. Correlation analysis will be performed between sleep quality score and pain intensity scores. The determinants of sleep quality will be evaluated by regression analysis. American College of Rheumatology criteria will be recruited. Demographics and disease related variables will be recorded.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Neuropathic pain; 4 Questions Neuropathic Pain Questionnaire	The DN4 questionnaire (4 Questions Neuropathic Pain Questionnaire) will be used. It is a clinician-administered questionnaire. It consists of ten items. Seven items related to pain quality (i.e. sensory and pain descriptors) are based on an interview with the patient. Three items are based on the clinical examination. The clinician assesses whether there is reduced sensation (hyposthesia) to touch or pinprick and whether light brushing increases or causes pain (allodynia). All of the positive items are scored as one point and total score is sum of the scores of these positive items. The diagnosis is based on 4/10 cut-off value.	through study completion, an average of 1 year
Secondary	Sleep quality	Jenkins Sleep Scale.The four-item questionnaire evaluates the frequency and intensity of certain sleep difficulties in respondents. Questions queries the number of days in which the patient was subjected to sleep problems. The maximum possible score is 20 and higher scores indicate much more sleep disturbance. A mean score of two or more is considered as sleep disturbance presence.	through study completion, an average of 1 year
Secondary	Depression and Anxiety; The Hospital Anxiety and Depression Scale (HADS)	The Hospital Anxiety and Depression Scale (HADS) was developed by Zigmond and Snaith in 1983. It is used to detect whether the patient is in the depressive or anxious status. It is not a diagnostic tool but gives to physician an idea about the patient's emotional status. It consists of fourteen items. Seven items are related to anxiety and the other seven depression	through study completion, an average of 1 year
Secondary	Quality of life level; KOOS (KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCORE) "Quality of Life" subgroup	KOOS evaluates the symptoms and functional problems related to knee OA and knee injury. It consists of five subscales. In this study authors intended to assess the life quality by using the quality of life level subscale of this scale.	through study completion, an average of 1 year
Secondary	Disability; KOOS (KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCORE) "Activities of Daily Life and Function" subgroup	Disability; KOOS (KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCORE) "Activities of Daily Life and Function" subgroup	through study completion, an average of 1 year
Secondary	Night pain (VAS, 0-10 cm) Participants will be asked to report the pain intensity that they feel on a line between 0 and 10, higher scores indicating more intense pain.	Participants will be asked to report the pain intensity that they feel on a line between 0 and 10, higher scores indicating more intense pain.	through study completion, an average of 1 year
