COMPARISION OF LIMB LENGTH DISCREPANCY BETWEEN UNILATERAL AND BILATERAL T.K.R.

Alpa Purohit

Abstract


AIMS & OBJECTIVES: To find out the difference of leg length in unilateral & bilateral TKR &find out clinical management of leg length discrepancy for improving patients function.

Purpose of the Study: To find out the difference of leg length between unilateral v/s bilateral T.K.R. and to find out the patients level of discomfort during walking.

METHODOLOGY: STUDY DESIGN: cross sectional observational study. Sample Population and Sample Size- 30 patients included according to criteria. In Group –A-15, unilateral Total knee replacement patients & in Group B -15, bilateral Total knee replacement patients were included. Sampling Technique: Convenient sampling according to selection criteria.

OUTCOME MEASURES: Limb length was measured by using Tape measurement method (TMM) in centimeters.

DATA COLLECTION & ANALYSIS: Data were collected from sterling hospital, Ahmedabad at post 3 months of surgery. Limb length measurement was done in the supine position with pelvis squared. The lower limbs were placed parallel to the body and limb length measurement (in centimeters) done from the anterior superior iliac spine to the medial malleolus using a measure tape. The measurement was taken twice by two different observers and the mean of the two values was recorded. Outcome parameters were analyzed with t-test in both group.

RESULTS: Data was analyzed by using Paired t-test. The t-value for unilateral T.K.R. was 9.73 (p<0.001) highly significant and bilateral T.K.R was 3.58 (p<0.05) respectively.

CONCLUSION: In unilateral T.K.R. there is a significant difference in leg length between operated & non-operated leg & in bilateral. There is no much leg length discrepancy between both operated legs. So in unilateral T.K.R., Limb length discrepancy is due to other leg’s arthritis condition which may cause imbalance in gait.
