Knee surgery, particularly Total Knee Replacement (TKR), is a complex procedure, especially for those suffering from knee osteoarthritis. At Gleneagles Hospital Kuala Lumpur, we recognize the challenges and prioritize the patient's voice in our approach to outcomes. We meticulously evaluate each TKR surgery at 3-month and 6-month intervals, utilizing the Knee Society Score (KSS) to measure and compare results against Minimal Clinically Important Difference (MCID) and Substantial Targets.
This precision-driven approach ensures that the impact of TKR transcends the surgical realm, resulting in significant improvements in both quality of life and mobility. This exemplifies our commitment to comprehensive and transformative orthopaedic care.
Patient’s Journey
Patient visits doctor to determine if TKR is recommended. | Patient is referred for same-day pre-operative physiotherapy. | PROMs (KSS) survey and pre-operative physiotherapy are conducted for the patient in rehab. | Patient undergoes surgery in GKL | Physiotherapy is administered for the patient during admission until discharge. | The patient attends physiotherapy sessions for three months. *3 months post-surgery PROMs (KSS) survey is conducted again to assess the patient's progress. | The patient continues physiotherapy sessions for an additional three months. *6 months post-surgery PROMs (KSS) survey is conducted to monitor the patient's progress. |
Patient Reported Outcome Measures (PROMs) Survey
Through our Patient Reported Outcome Measures (PROMs) Survey, we carefully measure our patient’s perception of health and functional well-being post-TKR surgery. PROMs are standardized questionnaires completed by patients, providing insights into health perception and functional well-being. The hospital conducts these surveys before and after treatment to understand any changes in the patient’s condition and quality of life. Working closely with patients and clinicians, PROMs give us a full picture of our patients' health and identify opportunities for continuous improvement.
Minimal Clinically Important Difference (MCID)
When it comes to knee surgery, Gleneagles Hospital Kuala Lumpur uses a benchmark called Minimal Clinically Important Difference (MCID). Our aim is for patients to see a minimum score increase of 9 points at 3 months and 40 points at 6 months post-surgery.
One notable achievement is reaching a 100% rate in the MCID benchmark within 3 and 6 months post-surgery, underscoring substantial improvements in pain reduction, daily function, and overall quality of life.
