Patients and methods
We prospectively assessed 60 consecutive patients as they were placed on the waiting list for revision THA using the WOMAC scale for osteoarthritis of the hip and the SF-36 general health status scale. The patients were asked to complete the expectation WOMAC. This questionnaire included exactly the same domains as the WOMAC, but the initial wording of the questions was changed, such that it asked the patients to estimate how they expected to feel 6 months after revision THA. All the questions
Results
The patients comprised 18 men and 42 women with an average age of 70 years (range, 37-89 years). The mean preoperative WOMAC score for pain was 13.4 (confidence interval [CI], 12.2-14.6; maximum possible score, 25); for stiffness, 5.9 (CI, 5.6-6.2; maximal possible score, 10); and for physical activity, 50.9 (CI, 47.2-54.6; maximum possible score, 85). The mean expectation WOMAC scores (for which the same potential range of scores is possible) were 7.4 (CI, 6.2-8.6) for pain, 3.5 (CI, 3.0-4.0)
Discussion
There has been great emphasis on the development of measures to determine outcomes after THA 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21. Several studies have assessed and compared different instruments for rating THAs 22, 23, 24, 25. Callaghan et al [24] compared 5 rating systems and found a great disparity in terminology and results. These authors noted no uniformity between the ratings and patients' impressions. Routine scores often are compiled with little regard for the goals and

3D biofabrication for soft tissue and cartilage engineering
2020, Medical Engineering and PhysicsCitation Excerpt :Over 180 000 patients therefore require total joint replacement surgery in the UK annually, a major operation which can result in incomplete satisfaction and residual symptoms, particularly in younger patients [160-163]. A rising number of patients also face the prospect of requiring revision joint replacement, a technically more complex and costly procedure with generally inferior clinical results [164-169]. Extensive efforts have therefore been made to search for novel and alternative strategies to aid and promote cartilage repair.
