Abstract:

Objective To explore the effect of motor imagery (MI) on knee function after unicompartmental knee arthroplasty (UKA).

Methods From January to September, 2022, 32 patients underwent UKA for the first time in Xuanwu Hospital were randomly divided into control group (n = 16) and experimental group (n = 16). All the patients accepted routine rehabilitation, and the experimental group accepted MI in addition, until four weeks after discharge. They were assessed with Oxford Knee Score (OKS), Visual Analogue Scale for pain (VAS), range of motion (ROM) of knee, and Timed Up and Go Test (TUGT) before and after treatment.

Results All the indexes improved after treatment (|t| > 2.517, P < 0.05), except ROM in the control group; and they improved more in the experimental group than in the control group (F > 7.999, P < 0.01), except the VAS score.

Conclusion MI can further improve the knee function after UKA, but do less for pain.

Key words: unicompartmental knee arthroplasty, motor imagery, rehabilitation
