Abstract

Objective

Proprioception, encompassing position sense, kinesthesia, and force sense, is crucial for maintaining joint stability. While prior studies suggest improved knee proprioception in knee osteoarthritis (KOA) patients following unicompartmental knee arthroplasty (UKA), assessments were limited to position sense or kinesthesia alone, failing to comprehensively evaluate proprioceptive changes. This study aimed to investigate the effects of UKA on all three proprioceptive components in KOA patients.

Methods

Seventy KOA patients and 29 healthy controls were recruited, with 36 patients undergoing UKA. Sixteen and 12 patients were measured at the 3-month and 6-month follow-up postoperatively. Proprioception (position sense at 30°, 45°, and 60 °, kinesthesia, and force sense) was assessed preoperatively and postoperatively at 3 and 6 months.

Results

Preoperatively, KOA patients exhibited significantly impaired position sense, kinesthesia, and force sense in both operated and contralateral knees compared to controls (p < 0.05). At 3 months postoperatively, position sense at 30°, kinesthesia and force sense in contralateral knee improved significantly (p < 0.05). Operated knee kinesthesia also improved (p < 0.05). No significant differences were observed between 3 and 6 months postoperatively.

Conclusions

KOA patients demonstrate reduced proprioception compared to healthy individuals. Postoperative improvements in proprioception, particularly in the contralateral knee, were evident at 3 months but plateaued by 6 months, underscoring the need for targeted proprioceptive rehabilitation post-UKA.

单腔人工膝关节置换术后膝关节本体感觉的改变

目的本体感觉包括位置感、运动感和力感，是维持关节稳定的关键。虽然先前的研究表明单室膝关节置换术（UKA）后膝骨关节炎（KOA）患者的膝关节本体感觉得到改善，但评估仅限于体位感或运动感，未能全面评估本体感觉的变化。本研究旨在探讨UKA对KOA患者所有三种本体感觉成分的影响。方法选取KOA患者70例，健康对照29例，其中36例行UKA。分别对16例和12例患者进行术后3个月和6个月的随访。术前和术后3、6个月分别评估本体感觉（30°、45°和60°位置感、运动感和力感）。结果与对照组相比，KOA患者手术前后双侧膝关节位置感、运动感、力感均明显受损（p <； 0.05）。术后3个月，对侧膝关节30°位置感、运动感、力感明显改善（p <； 0.05）。手术后膝关节运动感觉改善（p <； 0.05）。术后3 ~ 6个月无明显差异。结论与健康人相比，骨性关节炎患者本体感觉明显减弱。术后本体感觉的改善，特别是对侧膝关节，在3个月时明显，但在6个月时趋于平稳，强调了uka后有针对性的本体感觉康复的必要性。

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
