Detailed Description
Despite the recent advances in the understanding of pain mechanisms and the introduction of new drugs and new techniques in the postoperative management, pain after total knee arthroplasty (TKA) is still an unresolved issue. It affects the quality of life and rehabilitation of an important percentage of patients undergoing TKA. A recent study looked at the percentage of patients with chronic knee pain after knee replacement at a minimum of one year following surgery in 272 patients, 107 patients (nearly 40%) reported that they still had persistent pain at one-plus year following surgery. Central sensitization is now well established as an integral factor in many chronic pain states, including the commonly occurring knee and back pain. Many patients undergoing TKA are likely to have a significant degree of Central Sensitization, therefore the likely hood of high pain levels postoperative and persistent long standing pain after TKA is increased in this patient population.
Pulsed shortwave therapy negates central sensitization by imputing new

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Visual Analogue Pain
Time Frame: Change in pain levels over 3 months
|
The visual analog scale (VAS) has been used extensively for rating pain intensity in previous studies.
Postoperative pain at 2, 6, 10, 18, 26, 34, 42, 50, 58, 64, and 72 hours after surgery will be recorded using a 10-cm horizontal line with 1-cm vertical lines at each end labeled "no pain" (left side) and "worst possible pain" (right side).
VAS scores will also be recorded also at day 4, 7, 14 and 28 and finally at three months.
Different time point assessments are being conducted to look at the change in pain level from baseline through recovery.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Oxford Knee Score
Time Frame: 3 months
|
The Oxford Knee Score (OKS) is a 12-item patient-reported PRO specifically designed and developed to assess function and pain after total knee replacement (TKR) surgery (arthroplasty).
It is short, reproducible, valid and sensitive to clinically important changes.
|
3 months
|
The Knee Injury and Osteoarthritis Outcome Score
Time Frame: 3 months
|
The Knee Injury and Osteoarthritis Outcome Score (KOOS) is a knee-specific instrument, developed to assess the patients' opinion about their knee and associated problems.
The KOOS evaluates both short-term and long-term consequences of knee injury.
It holds 42 items in 5 separately scored subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL).
|
3 months
|
Pain Pressure Threshold
Time Frame: 3 months
|
Pain Pressure Threshold, is used routinely in clinical practice to assess pain sensitivity from musculoskeletal pain to indicate the level of pain sensitivity in individuals to central sensitization of the nervous system.
Testing will occur locally above the effected knee as well as peripherally on the distal interphalangeal joint.
|
3 months
|
The Pain and Sleep Questionnaire three-item index
Time Frame: 3 months
|
The Pain and Sleep Questionnaire three-item index (PSQ-3): A reliable and valid measure of the impact of pain on sleep in chronic nonmalignant pain of various etiologies.
|
3 months
|
Active Range of Motion
Time Frame: 3 months
|
Active range of motion (A-ROM) is an important component of the assessment of total knee replacement (TKR) outcome.
The goal of knee replacement recovery is to achieve flexion of 135 degrees.
Range of motion will be measured by observational method by two separate individuals.
|
3 months
|
Analgesic medication use
Time Frame: 28 days
|
Analgesic medication use for the postoperative period of 7 days as well as a further 21 days will be recorded - 28 day total.
