AbstractIntroductionTotal knee replacement (TKR) is the treatment of choice for the millions of individuals whose osteoarthritis related pain can no longer be managed through non-invasive methods. Although most patients report improvement in pain and functioning following TKR, up to 30% report after 1–2 years persistent pain that interferes with their daily function. Further knowledge on long term results are highly demanded. The present study is the first 5 year follow-up of all patients from a whole region.MethodsPatients were interviewed by letter concerning pain, overall satisfaction and forgotten joint score (FJS). In 2011, 607 patients in the region of North Denmark had a primary TKR, of which 20 was bilateral. Still alive are 546 patients. A total of 498 answered by letter (91%) of which 13 were not able to answer detailed due to psychological reasons.ResultsA total of 290 (59%) patients were very satisfied with their TKR, 140 (30%) were satisfied and 58 (12%) dissatisfied. Pain free were 269 (55%). 163 patients (33%) experienced moderate pain and 55 (11%) had strong pain. Dissatisfaction and pain were highly correlated, especially pain at walking: Among patients reporting strong pain, 35 (64%) scored higher than 6 on the VAS-average pain last 24 h versus 46 (84%) that scored higher than 6 on the VAS-pain after 30 min’s walk.ConclusionsAmong an unselected series of patients having TKR, 12% were dissatisfied and 11% still had strong pain 5 years later. Dissatisfaction was especially correlated with pain when walking. Thus, the association between dissatisfaction, pain at activity and the individual expectations should be further focused.
