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.

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.

Timed up & go Test
Total 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.
Time frame: First day after surgery and third or fourth day after surgery
Numeric Pain Rating Scale
An 11-point scale scored from 0 to 10: 0 = no pain, 10= the most intense pain imaginable
Time frame: up to four days after surgery
Quadriceps Muscle Strength
muscle strength measure by dynamometer (N⋅m)
Time frame: A 1 day before the surgery, first day after the surgery and third or fourth day after the surgery .
Elderly Mobility Scale
The 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.
Time frame: First day after the surgery and third or fourth day after the surgery
5 Times Sit to Stand Test
The 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.
Time frame: First day after the surgery and third or fourth day after the surgery
Hospitalization Duration
Number of days of hospitalization after the surgery- taken from the pa...
Time frame: At discharge (assessed up to day 10)
Surgery Duration
minutes- taken from the patient's file
Time frame: During the surgery
Consumption of Analgesics
taken from the patient's file
Time frame: At discharge (assessed up to day 10)
Occurrence of Falls
throughout the hospitalization- taken from the patient's file
Time frame: At discharge (assessed up to day 10)
Oxford Knee Score Questionnaire
The 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.
Time frame: A 1 day before the surgery
