Brief summary
Osteoarthritis (OA) is a common degenerative joint disorder associated with chronic pain at older age.It is known that patients with osteoarthritis experience nociceptive and neuropathic pain to varying degrees. Addition of molecules targeting neuropathic pain to conventional therapy has been shown to improve treatment response in the management of osteoarthritis.The aim of our study is to evaluate the effect of duloxetine and pregabalin on pain, functional capacity, quality of life, depression, anxiety and sleep patterns in knee osteoarthritis.
Detailed description
A total of 66 patients (aged 40-69) with knee osteoarthritis were randomized into two treatment groups to receive either duloxetine 60mg/day or pregabalin 300mg/day. The patients were evaluated before and one month after treatment and three months after treatment using the visual analog scale (VAS-pain), Neuropathic Pain Diagnostic Questionnaire (DN4), Short Form-36 (SF-36) Questionnaire, Western Ontario and McMaster University Osteoarthritis İndeks (WOMAC), Beck Depression Scale (BDS), Beck Anxiety Akalası (BAS), Pittsburg Sleep Quality Index (PSQI).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Assessing Visual Analog Scale Score Change in Patients | 0.,4., and 12. weeks | All patients were asked to score the severity of their current knee pain on a 10-cm visual analogue scale (VAS). |
| Neuropthic Pain Diagnostic Questionnaire (DN4) | 0.,4, and 12. weeks | There are 10 questions in the DN-4 including 7 questions related to pain quality and 3 questions that investigate the presence of tactile sensation, pinprick sensation, and allodynia. A total score 4/10 indicates neuropathic pain. |
| Assessing Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Score Change in Patients | 0., 4. and 12. weeks | The WOMAC consists of 24 questions that assess pain, stiffness, and problems with physical activities. The patient answers all questions on a 5-point Likert-type scale, and the total score ranges from 0 and 96. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessing Beck Depression Inventory Score Change in Patients | 0., 4. and 12. weeks | Symptoms of depression were evaluated by means of the Beck Depression Inventory |
| Assessing Short Form-36 (SF-36) Questionnaire Score Change in Patients | 0.,4.,and 12. weeks | The SF-36 has eight subscales and consists of a total of 36 questions. The subscales are vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health. A score of 0 is equivalent to maximum disability (poor quality of life), and a score of 100 is equivalent to no disability (good quality of life). |
| Assesing Beck Anxiety Inventory Score Change in Patients | 0.,4.,and 12. weeks | Current anxiete state of patients was assessed by means of the Beck Anxiety Inventory |
| Assessing Pittsburgh Sleep Quality Index Score Change in Patients | 0.,4.,and 12. weeks | Sleep quality assessments were performed by means of the Pittsburgh Sleep Quality Index |
