Comparison of the Functional Outcome of Arthroscopic PCL Reconstruction on The Basis of Lysholm Score & Tegner Activity Level

Abstract

Background: PCL injuries are increasing in our country due to growing number of motorcycle accidents and consequently we are getting more patients with PCL injuries in our hospitals. Isolated PCL injuries are less common (3%) than those with concomitant posterolateral corner (PLC) or other ligamentous injuries (97%).
Objective: To assess the comparison of the functional outcome of arthroscopic PCL reconstruction on the basis of lysholm score & tegner activity level.
Methodology: This prospective observational study was conducted in the department of Orthopaedic Surgery, BSMMU, Dhaka from July, 2019 to September, 2021. Within this period total 16 patients after considering the inclusion and exclusion criteria. All the data were compiled and sorted properly and the quantitative data was analyzed statistically by using Statistical Package for Social Science (SPSS-25). The results were expressed as percentage and mean ± SD and p<0.05 was considered as the level of significance at 95% confidence interval.
Result: Mean age of all study population was 31.56±4.94 years (22-40 year), where in maximum patients belonged to 26-35 years of age (62.6%). Mean duration of sufferings was 2.71± 0.82 months (range: 3-6 months), whereas majority of the study patients (75%) were suffered for <3 months. Values are expressed within parenthesis percentage (%) over column in total. Mean diameter of graft of all patients was 7.53 ± 0.34 mm (range: 7.00- 8.50 mm). The mean preoperative Lysholm score for 16 knees was 60±6.18 (Range, 50 to 74) and the mean postoperative Lysholm score was 88.56±4.31 (range, 79 to 97). Fifteen of 16 patients (93.7%) showed good or excellent results in the final assessment. The mean preoperative Tegner score for 16 knees was 2.94±0.93 (range, 2 to 5), whereas the mean postoperative Tegner score was 5.75±1.61 (range, 3 to 9). There were statistically significant improvements in Lysholm score (P <0 .001), Tegner score (P <0 .001).
Conclusion: Assessment of functional outcomes pre- and postoperatively were done using the Lysholm knee scoring scale. After follow up for 09 months, the analytical results showed patients achieved satisfactory knee function after PCL reconstruction by using a quadruple hamstring autograft
