A sleep disturbance after total knee arthroplasty

Area of Science:

• Orthopedic Surgery
• Sleep Medicine
• Pain Management

Background:

• Knee osteoarthritis (OA) significantly impacts elderly populations.
• Total knee arthroplasty (TKA) is a common procedure to restore function.
• Sleep disturbance is a recognized complication following TKA.

Purpose of the Study:

• To investigate sleep disturbances after TKA.
• To assess the impact of varying postoperative pain management strategies on sleep.
• To evaluate the temporal pattern of sleep quality post-TKA.

Main Methods:

• Prospective cohort study of 67 patients undergoing primary TKA.
• Sleep quality assessed using the Pittsburgh Sleep Quality Index (PSQI).
• Pain evaluated via Visual Analogue Scale (VAS) over three months post-operation.

Main Results:

• The study included a majority of female participants (83.6%) with a mean age of 64.2 years.
• No significant association found between age, gender, BMI, or diabetes history and PSQI scores.
• Sleep quality initially improved, peaked with disturbance at one month, then gradually improved.

Conclusions:

• Sleep disturbance following TKA requires comprehensive assessment.
• Multimodal strategies are essential for improving patient sleep satisfaction post-TKA.
