Abstract

Background

Proprioception has been defined as the perceived sense of knee joint position (joint position sense) and movement (kinesthesis) (1). The sensory input from the joint capsule, muscles, ligaments, skin improve proprioceptive acuity. With total knee arthroplasty (TKA) surgery articular cartilage, meniscuses, articular ligaments are removed. Also articular effusion and hematoma formation increase following surgery. Therefore, proprioceptive acuity decrease after TKA surgery (2). The proprioceptive improvement might prevent patients with TKA from falling down and increase their sense of security during physical activities. The clinical effect of neoprene knee sleeves on knee proprioception has been evaluated by studies in both injured and uninjured populations (3). But there is not any study research on the effect of neoprene knee sleeves on knee proprioception in patients with TKA.

Objectives

The aim of this study was to determine the effect of the neoprene knee sleeves on knee joint proprioception in patients with TKA.

Methods

Sixty patients (50 female/10 male) with a median age 64.95±8.84 years were included in the study. Knee joint proprioception of all the patients was evaluated with and without a neoprene knee sleeves preoperatively and at discharge. Patients attempted to replicate target angles (in knee joint angle 15°, 30°, 60°) using active knee extension movements in sitting position. The average of the 3 repetitions of active joint repositioning test was recorded position sense score. The angular displacements from the target angles (in knee joint angle 15°, 30°, 60°) at the end of the active reproduction tests were recorded as position sense deficit scores.

Results

Preoperatively (p<0.001) and after surgery (p<0.001) patients' proprioceptive acuity measured with neoprene knee sleeves in knee joint angle 15°, 30°, 60°, had a significant improvement. When the proprioceptive acuity measured without neoprene knee sleeves before and after surgery were compared, had a significant decrease in proprioceptive acuity (p<0.001) in early stage after TKA surgery. Also when the proprioceptive acuity measured with neoprene knee sleeves in knee joint angle 15°, 30°, 60° before and after surgery were compared, no significant statistical differences were observed (p>0.05).

Conclusions

In patients with TKA due to osteoarthritis, application of neoprene knee sleeves has increased the proprioceptive acuity. The current results suggest that neoprene knee sleeves might be used for improving proprioception in early stage of patients with TKA.
