A prospective study comparing sleep quality using Pittsburgh Sleep Quality Index at 8 weeks after robotic-assisted versus conventional total knee arthroplasty: a single-center study

Overview of the Study

Total knee arthroplasty (TKA) is important for relieving pain and enhancing life quality in patients with severe knee arthritis. However, many patients experience sleep problems after surgery, which can last for months and affect recovery.

Robotic-Assisted TKA vs. Conventional TKA

This study compared sleep quality in patients who underwent robotic-assisted TKA (RATKA) versus traditional TKA (CTKA). RATKA is more precise and less invasive, which may lead to better sleep after surgery.

Study Details

The study involved 68 patients who had unilateral TKA for severe osteoarthritis. They were randomly divided into two groups: 34 received RATKA and 34 received CTKA. All surgeries were performed under spinal anesthesia, and patients followed a standard pain management plan.

Measuring Sleep Quality

Sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) 8 weeks after surgery. Results showed that the RATKA group had a mean PSQI score of 5.68, which was significantly lower than the CTKA group’s score of 6.25. This indicates that patients who had RATKA experienced better sleep quality.

Key Findings

The study found that RATKA led to significantly better sleep quality compared to CTKA, likely due to less pain and better surgical outcomes. These results suggest that robotic-assisted techniques could improve recovery after knee surgery.

Future Opportunities

To build on these findings, future studies should involve larger and more diverse groups of patients and longer follow-up periods to confirm these benefits.

Measurable Outcomes and Goals

Clinics and patients should aim for clear goals regarding sleep quality improvement after TKA. This can help in assessing the effectiveness of different surgical techniques.
