Brief summary

The goal of this interventional study is to examine whether a pain management technique of combined femoral and popliteal nerve block is effective in total knee arthroplasty patients. The main questions it aims to answer are: Are there differences in postoperative outcomes? Does the nerve block, age, preoperative quadriceps muscle strength and Oxford Knee Score of the patient predict early functional ability? Participants underwent total knee arthroplasty and assessments. Researchers compared pain management techniques to assess effects on postoperative outcomes and identified the importance of preoperative variables a predictors of early functional ability. Further research is required to refine postoperative pain management strategies.

Interventions

PROCEDURECombined Femoral and Popliteal nerve block

Patients who receive a combined femoral and popliteal nerve block during surgery, fill out a questionnaire and undergo a muscle strength test before surgery, undergo functional tests, a muscle strength test and are asked about pain intensity after surgery.

Design outcomes

Primary

MeasureTime frameDescription
Timed up & go TestFirst day after surgery and third or fourth day after surgeryTotal time to arise from chair, walk 3 m, turn around, return to chair and sit down. Two trials performed and the faster of the two is recorded to the nearest 10th of a second.
Numeric Pain Rating Scaleup to four days after surgeryAn 11-point scale scored from 0 to 10: 0 = no pain, 10= the most intense pain imaginable
Quadriceps Muscle StrengthA 1 day before the surgery, first day after the surgery and third or fourth day after the surgery .muscle strength measure by dynamometer (N⋅m)

Secondary

MeasureTime frameDescription
Surgery DurationDuring the surgeryminutes- taken from the patient's file
Consumption of AnalgesicsAt discharge (assessed up to day 10)taken from the patient's file
Elderly Mobility ScaleFirst day after the surgery and third or fourth day after the surgeryThe Elderly Mobility Scale is a 20 point validated assessment tool for the assessment of frail elderly subjects. The The Elderly Mobility Scale is measured on an ordinal scale of 0-20, when Scores under 10 - generally these patients are dependent in mobility maneuvers; require help with basic activity of daily living, such as transfers, toileting and dressing. Scores between 10 - 13 - generally these patients are borderline in terms of safe mobility and independence in activity of daily living i.e. they require some help with some mobility maneuvers. Scores over 14 - Generally these patients are able to perform mobility maneuvers alone and safely and are independent in basic activity of daily living.
Oxford Knee Score QuestionnaireA 1 day before the surgeryThe Oxford Knee Score is a patient self-completion patient-reported outcome containing 12 questions on activities of daily living. It provides a single summed score which reflects the severity of problems that the respondent has with their knee. The Oxford Knee Score is scored 0-48 when Score 0-19 May indicate severe knee arthritis. Score 20-29 May indicate moderate to severe knee arthritis. Score 30-39 May indicate mild to moderate knee arthritis. Score 40-48 May indicate satisfactory joint function.
Occurrence of FallsAt discharge (assessed up to day 10)throughout the hospitalization- taken from the patient's file
5 Times Sit to Stand TestFirst day after the surgery and third or fourth day after the surgeryThe score is the amount of time (to the nearest decimal in seconds) it takes a patient to transfer from a seated to a standing position and back to sitting five times.
Hospitalization DurationAt discharge (assessed up to day 10)Number of days of hospitalization after the surgery- taken from the pa...
