Abstract | OBJECTIVE: METHODS: Patients who underwent TKA due to knee osteoarthritis were divided into two groups: those who experienced no or mild PPSP (Numerical Rating Scale [NRS] ≤ 3) (group 1, n = 91) and those who experienced moderate to severe PPSP (NRS > 3) (group 2, n = 183). Information on the characteristics of patients, comorbid diseases and pre-surgical NRS scores were obtained retrospectively from hospital charts. The follow-up time; pre-surgical and last control time walking distance; and ratings on the NRS, Pain DETECT Questionnaire ( PDQ) and patient satisfaction scales were recorded from the standard questionnaire presented to patients during the telephone interview. RESULTS: The mean follow-up time was 22.8 ± 12.3 months. The rate of moderate to severe PPSP among patients amounted to 66.7% after TKA. No neuropathic pain was found in Group 1. In Group 2, 22.9% of patients experienced neuropathic pain, the results for 18% of patients were uncertain, and 59% of patients did not experience neuropathic pain. Group 2 had worse scores on the patient satisfaction scale following the last control time compared with Group 1. Being widowed, having a low education level, being a housewife, having employment that requires physical effort, pre-surgical pain intensity at rest and pre-surgical restricted walking distance are risk factors for Group 2. CONCLUSIONS: PPSP and the neuropathic component in PPSP after TKA are not underestimated for pain management and patient satisfaction. Subgroups of patients, particularly widowers, having a primary school education level or under, housewives, people with jobs that require physical effort, individuals with intense pre-surgical pain during rest and those suffering from pre-surgical restricted walking distance, are at higher risk of developing PPSP following TKA.
