Improvement in Health-Related Quality of Life after Unilateral Total Knee Arthroplasty in Patients with Bilateral Knee Osteoarthritis

Purpose To review the outcome of unilateral total knee arthroplasty (TKA) in patients with bilateral knee osteoarthritis (OA) to determine whether unilateral TKA can achieve good health-related quality of life (HRQoL). Methods Records of 68 women and 25 men with severe bilateral knee OA who underwent unilateral TKA on the more symptomatic knee by a single surgeon and did not return for the second TKA within 2 years were reviewed. Outcome at 6 months and 2 years was assessed using the mental and physical component summary (MCS and PCS) of the Short-Form 36 (SF-36) for HRQoL as well as the Oxford Knee Score (OKS) and Knee Society Score (KSS) for knee-specific outcome. Results The SF-36, OKS, and KSS improved significantly after unilateral TKA. Respectively for MCS and PCS of SF-36, OKS, and KSS knee and function scores, 65%, 89%, 98%, 98%, and 98% of patients reported absolute improvement at 2 years. Respectively for PCS, OKS, and KSS function score that a minimal clinically important difference (MCID) was established, 77%, 96%, and 80% of patients achieved MCID at 2 years. Conclusion Unilateral TKA achieves good outcome in HRQoL at 2 years in patients with bilateral knee OA.

The scope of this paper was to study the relationship between pain intensity, health-related quality of life, disability, sleep quality and demographic data in elderly people with total knee arthroplasty (TKA). 24 subjects who had been subjected to TKA the previous month (4 females; 66 ± 9years) and 21 comparable controls (8 male; 70 ± 9years) participated in the study. Intensity of pain, and highest and lowest pain intensity experienced in the preceding week were collected. The Western Ontario and McMaster Universities index function, quality of life (Medical Outcomes Study Short Form 36), and Pittsburgh Sleep Quality Index were assessed. Age, gender, weight, height, body mass index were also collected. Individuals with TKA presented worse physical function (P < 0.01), social role (P = 0.01), physical performance (P < 0.01), pain (P = 0.04), disability (P = 0.04) and sleep quality (P = 0.03) than the controls. Higher intensity of pain was associated with lower physical function, social role, mental health, vitality and general health, and with higher disability and sleep quality. Disability and sleep quality were negatively associated with several quality of life domains. The associations between the intensity of pain, disability, quality of life and sleep reveal the multidimensional experience of TKA.
