Not Applicable
Not yet recruiting
Conditions
Total Knee Arthroplasty
Registration Number
NCT06678750
Lead Sponsor
Newton-Wellesley Hospital
Brief Summary

Evaluation of clinical outcomes and patient recovery in patients receiving TKA with traditional instrumentation systems compared to full arc of motion gap balancing using the Newton TM Knee Protocol

Detailed Description

The purpose of this study is to evaluate patient outcomes, recovery, and patient/surgeon satisfaction of individuals who undergo a total knee arthroplasty (TKA) using mechanical instrumentation (non-navigated) compared to individuals who undergo a TKA with a tibia first gap balancing surgical workflow using the NewtonTM Knee Protocol and navigation-assistance (ExachtechGPS®).

Primary Outcome Measures
NameTimeMethod
Patient satisfaction with TKA using patient reported KOOS JR QuestionnairePre-op, 4 weeks post-op, 12 weeks post-op, one year post-op

The KOOS, JR combines the pain, symptoms, and functional limitations into a single score.

Patient satisfaction with TKA using Oxford Knee Score (OKS) QuestionnairePre-op, 4 weeks post-op, 12 weeks post-op, one year post-op

The OKS is a patient reported questionnaire that measures function and pain with a single score.

Patient satisfaction with TKA using Forgotten Joint Score (FJS) QuestionnairePre-op, 4 weeks post-op, 12 weeks post-op, one year post-op

The Forgotten Joint Score assesses the ability of the patient to forget about their joint given successful treatment by assigning a single score to a series of questions.

Patient recovery from TKA using time from hospital stay to dischargePost-op measure in hours

The time of in-patient hospital stay will be measured (in hours).

Patient recovery from TKA by measuring number of outpatient visitsOne year post-op

Number of outpatient visits (scheduled and unscheduled)

Patient recovery from TKA by measuring number of PT visitsOne year post-op

Number of post-op PT visits

Patient recovery from TKA by measuring medication consumptionOne year post-op

Post-op, prescription medication will be recorded in number of pills and dosage

Patient recovery from TKA by measuring use of assisted walking devicesOne year post-op

Patient recovery from TKA by measuring the number of days using an assisted walking device following surgery.

Secondary Outcome Measures
NameTimeMethod
Knee alignment and soft tissue balanceOne time (during surgery)

Patients receiving a TKA NewtonTM Knee, soft-tissue balance will be measured intra-operatively by placing the Newton distractor at the trial reduction stage and acquiring the corresponding joint laxities through the arc of motion.
