A multicenter retrospective study by Kievit, A. et al.,1 has found that significantly more PKR patients returned to work within 3 months (73%) than TKR patients (48%).
The study compared 157 Oxford® PKRs with 167 TKRs, with similar age and gender mix at a minimum 2 years’ follow-up, aiming to address the following questions:
- Whether patients returned to work sooner following PKA compared to TKA
- Whether PKA patients had better WORQ (Work, Osteoarthritis, or joint-Replacement Questionnaire) function scores compared to TKR patients
- If PKA patients have higher workability (capable of working) scores and greater satisfaction regarding workability than TKR patients
The authors found more PKR patients return to work within 3 months (73% versus 48%) (p < 0.01). WORQ scores improved similarly in both groups. The dissatisfaction rates with workability were very similar.
By returning to work sooner after surgery, the authors concluded that it improves the quality of life for PKR patients and “allows them to participate actively in society”.
