Background: Anterior knee pain is a frequent condition after anterior cruciate ligament reconstruction (ACLR), but its origin remains uncertain. Studies have suggested that donor site morbidity in autologous bone–patellar tendon–bone reconstructions may contribute to patellofemoral pain, but this does not explain why hamstring tendon reconstructions may also present with anterior pain. Purpose: To evaluate the prevalence of anterior knee pain after ACLR and its predisposing factors. Study Design: Case-control study; Level of evidence, 3. Methods: We evaluated the records of all patients who underwent ACLR between 2000 and 2016 at a private facility. The prevalence of anterior knee pain after surgery was assessed, and possible risk factors (graft type, patient sex, surgical technique, range of motion) were evaluated. Results: The records of 438 patients (mean age, 30 years) who underwent ACLR were analyzed. Anterior knee pain was found in 6.2% of the patients. We found an increased prevalence of anterior knee pain with patellar tendon graft, with an odds ratio of 3.4 ( P = .011). Patients who experienced extension deficit in the postoperative period had an odds ratio of 5.3 of having anterior pain ( P < .001). Anterior knee pain was not correlated with patient sex or surgical technique. Conclusion: The chance of having anterior knee pain after ACLR was higher when patellar tendon autograft was used compared with hamstring tendon graft, as well as in patients who experienced extension deficit in the postoperative period.

Background: Complications and adverse events after anterior cruciate ligament (ACL) reconstruction are well known, but they have been underestimated in previous studies. Purpose: To describe the complications and adverse events after ACL reconstruction within a 2-year follow-up and analyze them in relation to the type of graft. Study Design: Cohort study; Level of evidence, 3. Methods: From 2000 to 2012, 958 patients with an isolated ACL injury underwent surgery by a single knee surgeon. ACL reconstruction was performed with the medial portal technique for the femoral tunnel and the use of bone–patellar tendon–bone (BPTB) or hamstring tendon graft. Patients were reviewed at 6 weeks and 3, 6, 12, and 24 months after surgery with the International Knee Documentation Committee score, plain radiographs, and the KT-1000 arthrometer. Results: Of 958 patients enrolled, 147 (15%) were lost at last follow-up. The 2 groups (bone–patellar tendon–bone [n = 257] and hamstring [n = 554]) were similar regarding the mean age at the time of surgery and preoperative anterior laxity. The main complications were as follows: anterior knee pain (n = 130 of 811, 16%), stiffness (n = 72, 8.8%), secondary meniscal lesions (n = 59, 7.2%), pain attributed to fixation (n = 79, 9.7%), ACL rerupture (n = 47, 5.7%), contralateral ACL ruptures (n = 24, 3%), patellar fractures (n = 3, 0.3%), infections (n = 9, 1%), and thromboembolic complications (n = 5, 0.6%). There was no significant difference between the grafts with respect to the frequency of joint stiffness, secondary meniscal lesions, or anterior knee pain. During the first 2 postoperative years, the percentage of patients with anterior knee pain was higher in the patellar tendon group (23.3% vs 12.6%, P < .001); however, this difference was not significant after the 2-year interval (3.1% vs 2.5%, P = .63). The percentage of patients with a rerupture of the graft was significantly lower in the patellar tendon group than in the hamstring group (25 of 811 [3.1%] vs 57 of 811 [7%], P = .023). Similar results were recorded regarding the pain related to the hardware material (7 of 811 [0.8%] in the BPTB group vs 113 of 811 [13.9%] in the hamstring group, P = .001). The percentage of ACL ruptures contralateral to the repair was higher in the patellar tendon group (41 of 811 [5%] vs 17 of 811 [2%], P = .016). Conclusion: The total rate of complications after an ACL reconstruction was 39%, and the surgical revision rate for any reason was 28%. Problems with the hardware material were more frequent in the hamstring group, leading to an increased rate of surgical revision. Anterior knee pain was initially higher in the patellar tendon group, but there was no significant difference in a 2-year interval. The rerupture rate was statistically higher in the hamstring group.
