Background: Several long-term (≥20 years) follow-up studies after anterior cruciate ligament (ACL) reconstruction have been published in recent years, allowing for a systematic evaluation of outcomes. Purpose: To summarize outcomes at ≥20 years after ACL reconstruction and identify patient and surgical factors that affect these results. Study Design: Systematic review; Level of evidence, 4. Methods: Prospective studies of primary ACL reconstructions with hamstring or bone–patellar tendon—bone (BTB) autograft via an arthroscopic or a mini-open technique and with a mean follow-up of ≥20 years were identified. When possible, the mean scores for each outcome measure were calculated. Factors identified in individual studies as predictive of outcomes were described. Results: Five studies met the inclusion and exclusion criteria with a total of 2012 patients. The pooled mean follow-up for patient-reported outcome measures was 44.2% (range, 29.6%-92.7%) and in-person evaluation was 33.2% (range, 29.6%-48.9%). Four studies (n = 584) reported graft tears at a mean rate of 11.8% (range, 2%-18.5%) and 4 studies (n = 773) reported a contralateral ACL injury rate of 12.2% (range, 5.8%-30%). Repeat non-ACL arthroscopic surgery (4 studies; n = 177) to the ipsilateral knee occurred in 10.4% (range, 9.5%-18.3%) and knee arthroplasty (1 study; n = 217) in 5%. The pooled mean of the International Knee Documentation Committee subjective knee function (IKDC) score was 79.1 (SD, 21.8 [3 studies; n = 644]). In 2 studies (n?= 221), 57.5% of patients continued to participate in strenuous activities. The IKDC-objective score was normal or nearly normal in 82.3% (n = 496; 3 studies), with low rates of clinically significant residual laxity. Moderate-severe radiographic osteoarthritis (OA) (IKDC grade C or D) was present in 25.9% of patients (n = 605; 3 studies). Medial meniscectomy is associated with increased risk of radiographic OA. Radiographic OA severity is associated with worse patient-reported knee function, but the association with knee pain is unclear. Conclusion: Currently available prospective evidence for ACL reconstruction with hamstring or BTB autograft provides several insights into outcomes at 20 years. The rates of follow-up at 20 years range from 30% to 93%. IKDC-objective scores were normal or nearly normal in 82% and the mean IKDC-subjective score was 79 points.

Anterior Cruciate

Background: Anterior cruciate ligament (ACL) tears are one of the most common traumatic knee injuries experienced by athletes. Return to sport is considered the pinnacle endpoint among patients receiving ACL reconstruction. However, at the time of return to sport, patients may not be participating at their previous levels of function, as defined by clinical metrics. Purpose: To establish when patients perceive maximal subjective medical improvement according to patient-reported outcome measures (PROMs). Study Design: Systematic review. Methods: A systematic review of the PubMed database was conducted to identify studies that reported sequential PROMs up to a minimum of 2 years after ACL reconstruction. Pooled analysis was conducted for PROMs at follow-up points of 3 months, 6 months, 1 year, and 2 years. Clinically significant improvement was determined between pairs of intervals with the minimal clinically important difference. Results: This review contains 30 studies including 2253 patients who underwent ACL reconstruction. Clinically significant improvement in the KOOS (Knee injury and Osteoarthritis Outcome Score) was seen up to 1 year after ACL reconstruction, but no clinical significance was noted from 1 to 2 years. Clinically significant improvement in the IKDC (International Knee Documentation Committee) and Lysholm questionnaires was seen up to 6 months postoperatively, but no clinical significance was noted beyond that. Conclusion: After ACL reconstruction, maximal subjective medical improvement is established 1 year postoperatively, with no further perceived clinical improvement beyond this time point according to current PROMs. The KOOS may be a more responsive metric to subjective improvements in this patient cohort than other patient-reported outcomes, such as the IKDC and Lysholm. Clinical Relevance: After ACL reconstruction, patients perceive interval subjective improvements until 1 year postoperatively.

Background: The Patient-Reported Outcomes Measurement Information System (PROMIS) is designed to advance patient-reported outcome (PRO) instruments by utilizing question banks for major health domains. Purpose: To compare the responsiveness and construct validity of the PROMIS physical function computer adaptive test (PF CAT) with current PRO instruments for patients before and up to 2 years after anterior cruciate ligament (ACL) reconstruction. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Initially, 157 patients completed the PROMIS PF CAT, Short Form–36 Health Survey (SF-36 physical function [PF] and general health [GH]), Marx Activity Rating Scale (MARS), Knee injury and Osteoarthritis Outcome Score (KOOS activities of daily living [ADL], sport, and quality of life [QOL]), and EuroQol–5 dimensions questionnaire (EQ-5D) at 6 weeks, 6 months, and 2 years after ACL reconstruction. Correlations between instruments, ceiling and floor effects, effect sizes (Cohen d), and standardized response means to describe responsiveness were evaluated. Subgroup analyses compared participants with and without additional arthroscopic procedures using linear mixed models. Results: At baseline, 6 weeks, and 6 months, the PROMIS PF CAT showed excellent or excellent-good correlations with the SF-36 PF ( r = 0.75-0.80, P < .01), KOOS-ADL ( r = 0.63-0.70, P < .01), and KOOS-sport ( r = 0.32-0.69, P < .01); excellent-good correlation with the EQ-5D ( r = 0.60-0.71, P < .01); and good correlation with the KOOS-QOL ( r = 0.52-0.58, P < .01). As expected, there were poor correlations with the MARS ( r = 0.00-0.24, P < .01) and SF-36 GH ( r = 0.16-0.34, P < .01 ). At 2 years, the PROMIS PF CAT showed good to excellent correlations with all PRO instruments ( r = 0.42-0.72, P < .01), including the MARS ( r = 0.42, P < .01), indicating frequent return to preinjury function. The PROMIS PF CAT had the fewest ceiling or floor effects of all instruments tested, and patients answered, on average, 4 questions. There was no significant difference in baseline physical function scores between subgroups; at follow-up, all groups showed improvements in scores that were not statistically different. Conclusion: The PROMIS PF CAT is a valid tool to assess outcomes after ACL reconstruction up to 2 years after surgery, demonstrating the highest responsiveness to change with the fewest ceiling and floor effects and a low time burden among all instruments tested. The PROMIS PF CAT is a beneficial alternative for assessing physical function in adults before and after ACL reconstruction.

Background: Several strategies have been studied to decrease the rate of infection after hamstring autograft anterior cruciate ligament (ACL) reconstruction. Our group started presoaking grafts with Vancomycin in November 2015 to decrease this risk. Purpose: The objective of the study is to compare the success of this protocol against the immediate previous period in which we did not use the protocol. Study design: Retrospective cohort. Level III. Methods: Consecutive periods were studied: April 2013-October 2015 (pre Vancomycin protocol) and November 2015- May 2018 (Vancomycin protocol). All patients that underwent a hamstring autograft primary ACL reconstruction during the periods studied were included. The final outcome was the presence of postoperative septic arthritis in both groups. Diagnosis of septic arthritis was made using the clinical picture plus cytological analysis of a joint aspiration (cell count > 50.000/uL + > 90% neutrophils) Statistical analysis was made using the Fisher’s exact test. Significance was set in p < 0.05. Results: 490 patients were included in the study, 230 in the pre Vancomycin protocol an 260 in the Vancomycin protocol. 4 postoperative septic arthritis were noted in the pre Vancomycin protocol (1.7%) while no septic arthritis was noted in the post Vancomycin protocol patients during the period studied. (p < 0.05) The 4 postoperative infections were presented at an average 21.7 days (range 16-25). Staphylococcus epidermidis was isolated in 2 of the cases, and in the other 2 no organism was isolated. Conclusion: Vancomycin presoaking of hamstring autografts in primary ACL reconstruction eliminated the risk of postoperative septic arthritis during the studied period compared to the immediate previous period, where no Vancomycin presoaking was used.

Background: The short-term outcomes of anterior cruciate ligament (ACL) reconstruction with bone–patellar tendon–bone or hamstring tendon (HT) graft are excellent with good clinical stability and patient-reported outcomes. Although some studies have reported the long-term outcomes of bone–patellar tendon–bone graft ACL reconstruction, few have reported the outcomes of HT graft ACL reconstruction. Purpose: To assess clinical and radiographic outcomes of HT graft ACL reconstruction with femoral cortical button fixation at a minimum 20-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: A prospective study was performed in which all patients undergoing isolated transtibial primary ACL reconstruction between 1994 and 1996 with HT graft and femoral cortical button fixation were assessed clinically and radiographically. Follow-up was obtained in 48 of 94 patients (51%). Median (interquartile range) age at operation was 31 years (26-39 years); median follow-up was 21 years (20-22 years); 65% were male; and 48% had meniscal injury at surgery and underwent partial meniscectomy. Graft rupture, reoperation, and contralateral injury rates were assessed; clinical stability was measured using the KT-1000 arthrometer; patient-reported outcomes were assessed (International Knee Documentation Committee [IKDC], Lysholm, Forgotten Joint Score, Tegner activity, Knee injury and Osteoarthritis Outcome Score [KOOS], Anterior Cruciate Ligament Quality of Life [ACL-QOL], EuroQol 5-Dimension 5-Level [EQ-5D-5L]); and radiographic osteoarthritis (defined as Kellgren-Lawrence grade ≥2) was assessed for the ipsilateral and the contralateral knee. Results: Graft rupture occurred in 4 patients (8%), contralateral injury in 4 patients (8%), and reoperation in 15 patients (31%), which consisted mainly of meniscal tears or hardware removal. In patients with an intact graft, excellent patient-reported outcome measures (PROMs) were noted, with a median Lysholm of 90 (78-100), subjective IKDC of 86 (72-95), and KOOS–Sports of 86 (58-100). There was low awareness of the operated knee (Forgotten Joint Score, 81 [60-96]) and good quality of life (ACL-QOL, 85 [75-94]; EQ-5D-5L, 0.87 [0.83-1.00]). Median side-to-side difference, as measured with the KT-1000 arthrometer, was 1 mm (-1 to 3 mm). Radiographic osteoarthritis was evident in 49% of ipsilateral and 10% of contralateral knees and was associated with meniscectomy at index surgery and decreased PROMs at follow-up. Conclusion: Long-term outcomes of transtibial HT graft ACL reconstruction with femoral cortical button fixation are generally good with a low failure rate, low awareness of the operated knee, and good clinical stability. Radiographic osteoarthritis was evident in approximately half of the patients at 20-year follow-up and was associated with meniscectomy at index surgery and decreased PROMs at follow-up.

Graft Diameter

Several studies have identified graft diameter as a risk factor for failure following anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to evaluate the effect of graft diameter on patient reported outcome measures (PROMS) following ACLR. We performed a retrospective review of prospectively collected data using a global surgical registry. 153 of 287 patients (53.3%) had complete data for each timepoint. Effect of graft diameter, graft type, femoral tunnel drilling technique, patient age, sex, and body mass index were evaluated. At 1-year post-operatively, a 1-mm increase in graft diameter was found to correlate with a 5.7-point increase in the Knee Injury and Osteoarthritis Outcome Score (KOOS) activity of daily living score (p = 0.01), a 10.3-point increase in the sport score (p=0.003), and a 9.8-point increase in the quality of life score (p=0.013). At 2-years post-operatively, a 1-mm increase in graft size was found to be marginally correlated with KOOS symptoms and sport scores. Patients undergoing hamstring autograft ACLR, increasing graft diameter can result in improved PROMS, specifically improved KOOS subscale scores at 1 and 2-years post-operative.

Background: Adult patients who succeed in returning to their preinjury levels of sport after anterior cruciate ligament (ACL) reconstruction have been characterized by a more positive psychological response. It is not known whether this relationship is valid for adolescent athletes. Purpose: To investigate psychological readiness to return to sport, knee-related self-efficacy, and motivation among adolescent (15-20 years old) and adult (21-30 years old) athletes after ACL reconstruction. A further aim was to compare athletes (15-30 years old) who had recovered their muscle function and returned to sport with athletes who had not. Study Design: Case-control study; Level of evidence, 3. Methods: Data were extracted from a rehabilitation-specific register 8 and 12 months after ACL reconstruction. Athletes previously involved in knee-strenuous sport who had undergone primary ACL reconstruction were included. Data comprised psychological patient-reported outcomes and results from 5 tests of muscle function. Comparisons were performed between age groups, between athletes who had and had not recovered their muscle function, and between patients who had returned to sport and not. Results: In all, 384 (50% females) and 271 athletes (52% females) were included at the 8- and 12- month follow-ups, respectively. Enhanced self-efficacy was reported at both follow-ups by adolescents and by athletes who had recovered their muscle function. Athletes who had recovered their muscle function reported higher ( P = .0007) motivation to achieve their goals. Subgroup analyses on patient sex revealed findings similar to those in the main analyses for females but not for males. Moreover, adolescent and adult athletes who had returned to sport reported significantly higher levels on the Knee Self-Efficacy Scale and the ACL–Return to Sport After Injury scale at both follow-ups. Conclusion: Adolescent athletes, especially females, perceived enhanced self-efficacy, had a higher return-to-sport rate, and were more motivated to reach their goals after ACL reconstruction compared with adults. Regardless of age, athletes who had returned to sport and athletes with more symmetrical muscle function had a stronger psychological profile.

Background: The safest and most effective technique for anterior cruciate ligament (ACL) reconstruction in skeletally immature patients is currently unknown. Purpose: To evaluate the functional and patient-reported outcomes of a specific all-epiphyseal ACL reconstruction technique in which the graft, bone tunnels, and fixation do not cross the knee growth plates. Study Design: Case series; Level of evidence, 4. Methods: Twenty-seven patients (23 boys, 4 girls; mean age, 11 years; range, 8-15 years) underwent an all-epiphyseal ACL reconstruction with a single femoral transverse epiphyseal tunnel and primarily split tibial epiphyseal tunnels. Outcomes were evaluated in terms of the manual Lachman test, range of motion, pain, return to activity, angular or leg-length deformity on imaging, and International Knee Documentation Committee (IKDC) or Pedi-IKDC score an average of 3.8 years postoperatively, with a minimum 2-year follow-up. Results: The mean IKDC score was 94 ± 11. There were no growth arrests, but 3 patients had knee overgrowth, and 2 required a subsequent guided growth procedure. The ACL graft failed in 4 patients (15%), and 2 patients had contralateral ACL tears (7%). There were 5 subsequent ipsilateral meniscal tears, 4 of which were retears of a repaired meniscus. Ipsilateral knee reinjury significantly correlated with the number of associated injuries at the time of index surgery ( P = .040) and the number of sports played ( P = .029). Conclusion: All-epiphyseal ACL reconstruction resulted in excellent long-term functional outcomes, despite a high rate of complications (48%) and secondary procedures (37%) in this highly active cohort. The incidence of graft failure was similar to other standard ACL reconstruction techniques for patients younger than 20 years.

Primary Acl Reconstruction

Background: Quadrupled (4-strand) hamstring tendon autografts are commonly used in anterior cruciate ligament (ACL) reconstruction, but there is significant variability in their diameter. The 5-strand hamstring autograft has been used as a means of increasing the graft diameter in patients with undersized hamstring grafts. Purpose: To report the outcomes of primary ACL reconstruction using 5-strand hamstring autografts in patients in whom the 4-strand configuration produced a graft diameter of <8 mm and to compare these outcomes with those of ACL reconstruction using 4-strand semitendinosus-gracilis autografts with a graft diameter of ≥8 mm. Study Design: Cohort study; Level of evidence, 2. Methods: The primary study group comprised 25 patients who underwent ACL reconstruction using a 5-strand hamstring autograft. The comparison group comprised 20 patients who underwent ACL reconstruction using a 4-strand hamstring autograft with a graft diameter of ≥8 mm. Interference screw fixation was used at the tibial and femoral ends for both groups of patients. Subjective questionnaires, including the Knee injury and Osteoarthritis Outcome Score (KOOS), the Lysholm score, and the Physical Component Summary and Mental Component Summary of the Short Form–36 (SF-36), were administered preoperatively as well as at 1- and 2-year follow-up visits. Results: There were no significant differences in the patient demographics and preoperative scores between the 2 groups. The mean graft diameter was 9.06 ± 0.60 mm in the 5-strand group and 8.13 ± 0.32 mm in the 4-strand group ( P < .05). There was no statistically significant difference between groups on postoperative Lysholm, KOOS Pain, KOOS Symptoms, KOOS Activities of Daily Living, KOOS Sports, KOOS Quality of Life, and SF-36 Physical Component Summary scores. Conclusion: In primary ACL reconstruction, the 5-strand hamstring autograft achieves clinical outcomes that are comparable to those of the 4-strand hamstring autograft with a graft diameter of ≥8 mm. The 5-strand graft technique is therefore a useful means of increasing the graft diameter when faced with an undersized hamstring graft.

Tendon Autograft

Background: Patellofemoral problems are not uncommon among post-anterior cruciate ligament (ACL) reconstruction patients. Hamstring autograft harvesting-related factor is one of the suspected causes. A lack of tibiofemoral internal rotation force due to strength deficit causes the patella tends to shift laterally. Purposes: Peroneus longus tendon has been proposed as an alternative graft source due to its adequate tensile strength and minimal donor site morbidity to the knee biomechanics, including the patellofemoral joint. This tendon does not cross the knee joint and thus does not affect patellofemoral alignment and biomechanics. This study aims to compare patellofemoral problems between hamstring and peroneus longus autograft harvested-patients following ACL reconstruction. Material and methods: Thirty-one subjects who underwent primary single-bundle ACL reconstruction between September 2018 and September 2019 and met the inclusion criteria were grouped into the hamstring group (n=16) and peroneus longus group (n=15). Both groups were evaluated retrospectively. The follow-up assessment was conducted on the phase II rehabilitation program. The assessed variables were pain, crepitus, and the Indonesian-validated Kujala score. Results: No significant differences in pain and crepitus were found between both groups. There were significant differences in the Kujala score between both groups (P < .001). The peroneus longus group reported an averagely higher score than the hamstring group. Conclusion: Single bundle ACL reconstruction using peroneus longus tendon autograft produces less patellofemoral symptoms and functional limitation than using hamstring tendon autograft.
