Brief Summary:
Total knee arthroplasty (TKA) is the most common joint replacement surgery and its incidence is expected to increase 673% to 3.48 million procedures annually by 2030. After more than 20 years of follow-up data, TKA is confirmed to be an effective treatment for knee osteoarthritis, however, postoperative pain management continues to be a challenge despite advances in surgical techniques and anesthetic practice to minimize discomfort and enhance recovery. This acute post-surgical pain caused by extensive tissue damage and inflammation in TKA leads to restricted post-operative knee range of motion (ROM) and ability to mobilize.

Primary Outcome Measures :
  1. Difference in Pain at 2 weeks: visual analog scale [ Time Frame: 2 weeks ]
    Pain assessed using 100mm visual analog scale (0 to 100 worst possible pain)

Secondary Outcome Measures :
  1. Difference in Pain at 5-7 days: visual analog scale [ Time Frame: 5-7 days ]
    Pain assessed using 100mm visual analog scale (0 to 100 worst possible pain)

  2. Difference in Patient Satisfaction: Questionnaire [ Time Frame: 2 weeks ]
    Questionnaire ranging from 1 (Very satisfied), 2 (Satisfied), 3 (Neither satisfied nor dissatisfied, 4 (Dissatisfied), and 5 (Very dissatisfied).

  3. Difference in Quality of Life: SF-36 [ Time Frame: 2 weeks ]
    Assessed by SF-36 (0-100 scale with 100 representing no disability)

  4. Difference in Subjective Outcome [ Time Frame: 2 weeks ]
    Oxford Knee Scale (score 0 most severe symptoms to 48 least symptoms)

  5. Difference in pain medication consumption [ Time Frame: 2 weeks ]
    opioid consumption (morphine equivalents)

  6. Difference in range of motion between baseline and 2 weeks [ Time Frame: 2 weeks ]
    degrees the knee joint can move

  7. Length of Hospital Stay [ Time Frame: 5 days ]
  8. Difference in Number of Readmissions [ Time Frame: 2 weeks ]
