Higher Infection Rate after ACL Reconstruction with Hamstrings Tendon Autografts Compared with Bone Patellar Bone Tendon Autografts: A Review.

Infection after anterior cruciate ligament reconstruction is a rare but devastating complication resulting in a deleterious impact on knee function as well as an increased related cost for treatment and rehabilitation for the patients. There are conflicting reports regarding the rate of infection between bone patellar tendon bone (BPTB) and hamstrings tendon (HT) autografts for anterior cruciate ligament reconstruction. Therefore, we performed this review to summarize all the available data regarding the risk of infection after ACL reconstruction, to provide insight on the infection risk between BPTB and HT autografts, and to discuss current recommendations for the diagnosis and treatment of these infections. The incidence and risk of infection after ACL reconstruction with HT graft is higher compared with BPTB grafts. The most commonly subacute and late infections, quadruple type, need for cannulated instruments for harvesting, size and shape and fixation of the extra-tunnel material of the HT are important risk factors for infection. Combined antibiotics administration and adequate arthroscopic lavage and debridement are the optimal treatments for ACL reconstruction infection. Early diagnosis and treatment is the most important predictor for graft retention, which accounts more commonly for BPTB grafts. The treating physicians should be aware of the higher incidence of infection after ACL reconstruction with HT graft, as well as for the need for a high clinical suspicion for early diagnosis of the infection. These will increase the possibility of eradication of the infection and retention of the graft.
