Influence of Total knee replacement on concomitant back pain and its correlation with functional outcome and patient satisfaction.

All the patients undergoing primary TKR meeting inclusion criteria with or without LBA during study period were taken into study.

Group A: With the low backache

Group B: Without low backache (control group)

 All the patients were clinically examined and functional scores recorded. The scores taken were VAS score for pain, Oswestry disability index for back pain, SF-12 for patient-reported outcome measure and Knee society score for knee function.

 Radiologically, Both groups- Standard TKR Protocol radiographs ( Alignment Xray, Knee Anteroposterior and skyline views) taken.

•Whole spine Xray- AP, lateral (Standing)

•Dynamic views â€“ if symptomatic

•MRI ( to stratify based on diagnosis)- if symptomatic

 The patient will undergo standard total knee replacement and postoperative protocol. After total knee replacement, both groups assessed with clinical scores and radiological criteria at 6 months and 1 year follow up.

 Statistical analysis used for comparison between groups:

•       Student’s t-test for continuous variables

•       Chi-squared test and Fisher’s exact test for categorical variables.

For comparison between pre- and postoperative data within a group:

•       Paired t-test or Wilcoxon signed-rank test

•       Correlation- assessed by the Spearman coefficient.

•       Statistical significance was considered for P values less than 0.05
