Change in Lower Quarter Y-Balance Test (YBT-LQ) (Dynamic Balance) From Baseline to 6 Weeks Following Total Knee Replacement
Lasso di tempo: Baseline (Pre-Operative) to 6 weeks following total knee replacement
|
The lower quarter y-balance test (YBT-LQ) is a test of dynamic balance in unilateral stance that has been deemed to be reliable and valid.
The YBT-LQ consists of each patient standing on one leg and reaching as far as they can with their non-stance leg in the anterior, posteromedial and posterolateral direction while standing on the other foot on a centralized stance platform.
The composite score is calculated as the sum of the three reach directions divided by 3 time the limb length and will be reported as a percentage of limb length.

Change in University of California, Los Angeles (UCLA) Activity Score From Baseline to 52 Weeks Following Total Knee Replacement.
Lasso di tempo: Baseline and 52 weeks following total knee replacement
|
The UCLA activity score is a validated patient reported outcome of overall physical activity.
Results on a scale of 1 to 10, 1 is "Wholly Inactive, dependent on others, and can not leave residence" and 10 is "Regularly participates in impact sports".

Change in Knee Injury and Osteoarthritis Outcome Score (KOOS) Total From Baseline to 52 Weeks Following Total Knee Replacement.
Lasso di tempo: Baseline (Pre-Operative) and 52 weeks following total knee replacement
|
The KOOS is a standardized and validated patient outcome score that assesses functional limitation in patient with knee problems.
KOOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport/Rec) and knee related Quality of life (QOL).
The previous week is the time period considered when answering the questions.
Standardized answer options are given (5 Likert boxes) and each question is assigned a score from 0 to 4. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale.

Change in Forgotten Joint Score (FJS) From 6 Weeks to 52 Weeks Following Total Knee Replacement.
Lasso di tempo: 6 weeks and 52 weeks following total knee replacement
|
The FJS is a patient reported measure of how bothersome the total joint replacement is for them, how much it affects daily activity and how much they are aware of the implant.
The FJS is a 12-question survey regarding functional outcome, pain, stability, daily living, activity and sport.
Scoring is from 0 to 4 with 0 as the best outcome; a low score means high satisfaction.
Not all questions must be answered to score, all responses are summed and the total is divided by number of completed items multiplied by 25, with the final result subtracted from 100.
The score range is from 0 to 100 with the highest score of 100 indicating the best outcome (the joint is completely "forgotten") and 0 indicating the worst outcome.

Knee Society Score (KSS)
Lasso di tempo: Baseline (Pre-Operative), 6 weeks and 52 weeks following total knee replacement
|
The KSS is a patient reported measure of knee function that is specific to patients who are scheduled to receive or have previously had a total knee replacement.
This outcome measures both patient reported pain and function changes from prior to surgery through recovery.
The score range is from 0 to 100.
The highest score of 100 points will be obtained by a well-aligned knee with no pain, 125 degrees of motion, and negligible anteroposterior and mediolateral instability.

Sit to Stand Time
Lasso di tempo: Baseline (Pre-Operative), 6 weeks and 52 weeks following total knee replacement
|
The sit to stand test requires patients to stand up and sit down as many times as possible in 10 seconds from a standard arm chair.
|

Timed Get up and go
Lasso di tempo: Baseline (Pre-Operative), 6 weeks and 52 weeks following total knee replacement
|
The timed up and go requires a patient to rise from a chair walk three meters around a piece of tape and return to the chair again as quickly as possible.
