Table 1.
Combined reconstruction |
No need for second operation as in staged reconstruction |
Saves time of patient |
Lower risk of ACL graft failure |
No negligence of MCL reconstruction |
POL reconstruction |
Reconstruction of both MCL and POL |
Nearly anatomic reconstruction of MCL |
POL plays key role in limiting internal rotation with knee in full extension10https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5796970/11 |
Graft choice |
Avoids allograft comorbidities, less cost, more incorporation |
Avoids risk of fracture of patella, early rehabilitation |
Preserves ipsilateral semitendinosus, no more weakening of medial side of knee |
Anatomic graft position and graft shape |
Graft suspension |
Adequate graft length for MCL and POL reconstruction |
More graft fixation by graft anchorage at distal end of ACL tibial tunnel |
Single tibial tunnel |
One interference screw is used for fixation of both ACL and MCL grafts at tibial tunnel |
Little morbidity to patient and with less cost |
Minimizes number of tibial tunnels |
Avoids tunnel collision and transection in medial tibial cortex |
Avoids graft rupture and weakening or fracture of medial tibial cortex |
Preserves bone stock at medial tibial cortex |
ACL, anterior cruciate ligament; MCL, medial collateral ligament; POL, posterior oblique ligament.
