Abstract

Background Knee range of motion (ROM) at discharge following total knee arthroplasty is used as a clinical indicator of performance. At least 90 degrees of flexion is standard discharge criteria for many hospitals.

Objectives To investigate whether the discharge criteria is realistic in patients with TKA.

Methods 13 patients (11=female, 2=male) who underwent unilateral TKA were included in this study. Mean age was 68.46±7.52 years, mean body mass index (BMI) was 30.14±5.6 kg/m2. Hospitalization duration was recorded. Knee flexion and extension degree were measured actively with goniometer during heel sliding on discharge day. Oxford Knee Score (OKS) was used to evaluate physical function and pain before surgery. Overall scores ranges from 0 (worst) to 48 (best). Descriptive statistics were used to analyse the data using SPSS v22.

Results Hospitalization duration was 5.07±1.25 days. Knee flexion degree and knee extension limitation were found 79.15±20.84° and 12.92±7.31°, respectively. Oxford Knee Score was calculated 19±8.30 point. Patients' results were given at Table 1.

Patients' results

Conclusions Patients have noticeable extension limitations at discharge. It should follow in the upcoming days. Nearly half of the patients flexed their knee less than expected. Due to the fact that discharge criteria for knee flexion is unrealistic. It should be investigate whether patients with less knee flexion degree can gain function as patients with more knee flexion degree.
