Abstract
We present the results of a prospective study on the functional outcome from total knee replacement (TKR) in young versus old patients. American Knee Society and pain scores over ten years post TKR were compared using a cohort of young patients (≤55 years) and a control group of patients ≥56, matched for ASA, body mass index and preoperative condition. A total of 24 young and 24 older knees were analysed. All scores improved significantly over time. There was no statistical differences over 10 years in pain (p = 0.436) and knee performance (0.618). Overall function was consistently higher in the younger group (p = 0.004). TKR in younger patients produces similar outcomes in terms of pain and function compared with older patients and we feel that TKR should not be withheld on account of age alone.

We present the results of a prospective study on the functional outcome from total knee replacement (TKR) in young versus old patients
We identified 40 Knees in 26 patients who were 55 years or younger at the time of primary TKR and within a time frame that would allow 10 years of follow up
Summary
Total Knee Arthroplasty (TKA) is a proven treatment for severe joint pain in osteoarthritis of the knee. This intervention is well established in the elderly with predictable and reproducible results [1,2,3,4]. There are a few reports showing favourable outcomes in the under 55 age group [6,7,8]. These series contain mainly patients suffering from rheumatoid arthritis and performed by surgeons in specialist centers [9]. It is not clear that these results would be reproducible in general orthopaedic practice [10]
