Summary: single stage patellar tendon repair with Arthroscopic ACL reconstruction gives good results with supervised physiotheraphy.Patellar tendon injury with MLKI requires staged manner and rehabilitaion is prolonged to get extensor function

Background

Results of largest case series of concomitant patellar tendon tear with Anterior cruciate ligament and multiligament knee injuries (MLKI) injuries following road traffic accident (fall from motor bike) from Level 1 - Tertiary care Trauma centre were assessed and reported.

Methods

Retrospective case series of patients operated between 2010 and 2019 with concomitant patellar tendon tear with ACL and MLKI including bony avulsion injuries. Peri-articular fractures around the knee, isolated cruciate and MLKI without patellar tendon tears were excluded. N=31 patients (1 female and 27 male) divided into 2 groups, Group 1 (11 patients) Patellar tendon tear and ACL tear and group 2 (20 patients) Patellar tendon tear with MLKIs. Patients were taken up for single stage/ staged repair and reconstruction depending on the severity and associated injuries. All the patients were followed up regularly and IKDC and Lyshom`s score were taken and Objective radiological stress x-rays were taken from 6 months postoperatively and during each follow up.

Results

The mean age was 35.09+/-11.96 SD(group1) and 36.55+/-11.89 SD(group2). The average follow-up was 34.45 months +/- 12.86SD (group 1) and 35.3 months +/- 15.75 SD (group2). Mean postoperative Lysholm score and IKDC score of the group 1 were 91.09 (SD 3.83) and 83.68(SD 3.68) and group 2 were 81.35(SD7.96) and 71.85 (SD8.12) respectively and the difference in mean was statistically significant as p value of 0.01. Mean postoperative ROM of the two groups were 132.73 (SD 6.46) (Group 1) and 111.75 (15.75) (Group 2) and the difference in mean was statistically significant as p value <0.01. Residual lag of 200 seen in all patients, Knee extensor lag restored by 3rd month in group and 6th month in group 2. group 1 the Mean post op laxity for ACL is 2.65mm (+/-0.7) whereas in group 2 is 2.17mm(+/-1.2) for ACL, 1.97(+/-2.16) for PCL, medial laxity 5.07(+/-12.18), lateral laxity 1.01(+/-1.76) and SD of of Knee stiffness seen in 1 patient and superficial infection in 2 patients.

Conclusion

Single stage PT repair with ACL reconstruction gives adequate stability and extensor lag is eminent and needs supervised physiotherapy to restore the extensor function. PT with MLKI is a challenging scenario needs can be performed in staged manner depending on the combination of the injuries. Restoration of extensor function is delayed and needs prolong rehabilitation.
