Background: Historically, outcomes of posterior cruciate ligament (PCL) reconstructions have been less predictable and reported to yield inferior results when compared with those for anterior cruciate ligament (ACL) reconstructions. Purpose: To report on the outcomes of double-bundle PCL reconstructions (DB PCLRs) in isolated versus combined injuries and acute versus chronic PCL reconstructions. To compare the outcomes of isolated DB PCLR with isolated ACL reconstruction. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who underwent a primary endoscopic DB PCLR for complete PCL tears (grade III) between May 2010 and March 2015 were reviewed. Patient-reported outcome scores (Tegner, Lysholm, WOMAC [Western Ontario and McMaster Universities Osteoarthritis Index], SF-12 [12-item Short Form Health Survey]) and objective posterior stress radiographs were collected preoperatively and at a minimum 2 years postoperatively. A cohort subanalysis was additionally performed between isolated and combined PCL reconstruction and acute versus chronic PCL reconstruction. Patients who underwent isolated ACL reconstructions over the same inclusion period (2010-2015) were selected as a comparison group. Results: One hundred patients who underwent DB PCLR were included in this study. There were 31 isolated PCL injuries, and 69 patients had concurrent combined PCL injuries requiring surgery. The mean follow-up for the PCL cohort was 2.9 years (range, 2-6 years). The median Tegner activity score improved from 2 to 5, Lysholm from 48 to 86, WOMAC from 35.5 to 5, and SF-12 Physical Component Summary from 34 to 54.8 (all P values <.001). The mean side-to-side difference in posterior tibial translation on kneeling stress radiographs improved from 11.0 ± 3.5 mm preoperatively to 1.6 ± 2.0 mm postoperatively ( P < .001). There were no differences in postoperative functional scores between isolated PCL reconstructions and PCL-based multiligament reconstructions (all P values >.229). There was no significant difference in the reported outcome scores between acute and chronic reconstructions (all P values >.087) except for Tegner scores ( P < .001) and patient satisfaction ( P = .011) favoring acutely treated PCL injuries. There were no significant differences between patients who had an isolated DB PCLR and patients who underwent an isolated ACL reconstruction (n = 141) in postoperative outcome scores (all P values >.064). Conclusion: Significantly improved functional and objective outcomes were observed after anatomic DB PCLR at a mean 3 years’ follow-up, with low complication rates, regardless of concomitant ligamentous injury or timing to surgery. Additionally, contrary to previous reports, comparable subjective and functional clinical outcomes were achieved compared with an isolated ACL reconstruction control cohort.

Objectives: 1) To report on the outcomes after double-bundle PCL reconstructions in isolated versus combined injuries and acute versus chronic PCL tears and 2) to compare the outcomes of isolated double-bundle PCL reconstruction (DB PCLR) to isolated ACL reconstruction (ACLR). Methods: All patients who underwent a primary arthroscopic assisted DB PCLR for grade-III isolated or combined PCL injuries between May 2010 and March 2015 were reviewed. Patient reported outcome scores (Lysholm, Tegner, Western Ontario and McMaster Universities Arthritis Index (WOMAC), 12 item Short Form Health Survey (SF-12) Physical Component Summary (PCS) and patient satisfaction with outcome) and objective posterior stress radiographs were collected preoperatively and at a minimum of two years postoperatively. Cohort subanalyses comparing isolated versus combined, and acute versus chronic PCL reconstructions were also performed. Patients who underwent isolated ACLR over the same inclusion period were selected as a comparison group. Results: One hundred patients that underwent DB PCLR were included in this study. There were 31 isolated PCL injuries and 69 combined PCL injuries and the mean follow-up was 2.9 years (range 2-6 years). The median Tegner activity score improved from 2 to 5, Lysholm from 48 to 86, WOMAC from 35.5 to 5, and SF-12 PCS from 34 to 54.8 (all p values <0.001). The mean side-to-side difference (SSD) in posterior tibial translation on kneeling stress radiographs improved from 11.0 mm preoperatively to 1.6 mm postoperatively (p<0.001). There were no significant differences in postoperative functional scores between isolated PCL reconstructions and combined PCL reconstructions (all p values >0.229). The mean SSD in postoperative posterior tibial translation on stress radiographs was 1.2 ± 1.1 mm for isolated PCL tears and 1.7 ± 2.2 mm for combined PCL tears. The improvement in posterior tibial translation from preoperative to postoperative was significant for both the isolated and combined PCL injury groups (p<0.001). Only the Tegner score (p<0.001) and patient satisfaction (p=0.011) were significantly different postoperatively between acute and chronic reconstructions, both favoring acutely treated PCL injuries. The mean SSD in posterior tibial translation on stress radiographs improved from 11.6 ± 3.1 mm preoperatively to 1.9 ± 2.5 mm postoperatively (p<0.001) for acute PCL tears, and 10.3 ± 3.7 mm to 1.2 ± 1.0 mm (p<0.001) for chronic PCL tears. There were no significant differences in postoperative outcome scores between patients that underwent an isolated ACLR or isolated DB PCLR [all p values >0.064]. Conclusion: Significantly improved functional and objective outcomes were observed after anatomic-based DB PCLR at a mean 3 years follow-up, regardless of concomitant ligamentous pathology or timing to surgery. Posterior tibial translation was restored to near normal after DB PCLR. Additionally, contrary to previous reports, similar results were achieved compared to a control isolated ACLR cohort.

Background: Meniscal and chondral lesions are commonly associated with anterior cruciate ligament (ACL) tears, and these lesions may play a role in patient outcomes after ACL reconstruction. Purpose: To determine the effects of the presence and location of meniscal and chondral lesions at the time of ACL reconstruction on patient-reported outcomes at a minimum 2-year follow-up. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with no prior knee surgery who underwent primary ACL reconstruction by a single surgeon between 2010 and 2014 were included in this study. Those meeting inclusion criteria were divided into the following groups based on the arthroscopic diagnosis: patients without concomitant meniscal or chondral lesions, patients with isolated meniscal lesions, patients with isolated chondral lesions, and patients with both chondral and meniscal lesions. Patient-reported outcomes (Short Form–12 [SF-12] physical component summary [PCS] and mental component summary [MCS], Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], and Lysholm scale) were assessed at a minimum of 2 years from the index surgery. Results: A total of 151 patients met the inclusion criteria and were included in the study. The mean age at the time of surgery was 36.2 years (range, 14-73 years), and the mean follow-up was 3.2 years (range, 2.0-5.6 years). At the time of surgery, 33 (22%) patients had no concomitant lesions and served as the control group, 63 (42%) patients had isolated meniscal lesions, 21 (14%) patients had isolated chondral lesions, and 34 (22%) patients had both chondral and meniscal lesions. There was significant improvement in all outcome scores postoperatively for the 3 groups ( P < .05 for all outcome scores). The presence of a meniscal tear and laterality of the meniscal lesion did not have a negative effect on any postoperative outcome scores. Patients with isolated chondral lesions had significantly lower postoperative WOMAC scores compared with patients without chondral lesions ( P < .05). No significant differences were found for all other scores. Patients with patellofemoral chondral lesions had significantly lower postoperative SF-12 PCS and Lysholm scores than patients with tibiofemoral chondral lesions ( P < .05). Conclusion: Patients with ACL tears achieved improved functional scores at a mean 3.2 years after ACL reconstruction. While meniscal lesions did not affect postoperative outcomes in the short term, chondral lesions were identified as a predictor for worse outcomes.

Active Patients

Background: Results of anterior cruciate ligament (ACL) reconstruction are traditionally excellent in younger and nonarthritic patients. During the past few decades, people older than 60 years have become more active than ever, with more demanding physical lifestyles. An increase also has been noted in active patients with diagnosed ACL injuries. More patients are requesting treatment for ACL deficiency in hopes of returning to preinjury levels of activity. Purpose: The aims of this study were to evaluate the results of ACL reconstruction in patients older than 60 years in terms of functional recovery, return to sports, and postoperative incidence of osteoarthritis and to compare their results with published results of different age groups. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients older than 60 years with isolated ACL tear and no established osteoarthritic lesions (Ahlbäck grade 1 or no arthritis) who were treated from 2008 to 2013 were retrospectively included in this study. Primary ACL reconstruction was performed with the same technique in all patients by means of single-bundle autologous hamstring tendon graft. Meniscal injuries were treated with partial debridement when required. No further treatment on cartilage lesions was performed. Postoperative rehabilitation was the same in every case. The International Knee Documentation Committee (IKDC) objective grade, Lysholm score, and Knee injury and Osteoarthritis Outcome Score (KOOS) were assessed before and after surgery, and the Anterior Cruciate Ligament–Return to Sport after Injury (ACL-RSI) score was recorded during the final follow-up. Postoperative incidence of osteoarthritis was evaluated on weightbearing radiographs during final follow-up, and anteroposterior laxity was measured pre- and postoperatively with the use of stress radiographs. Results: Twelve patients with mean age (±SD) of 61.0 ± 1.4 years at the time of surgery were included. They were followed-up for a mean period of 49.6 ± 24.0 months. Eight patients had associated meniscal tears, and 6 patients had International Cartilage Repair Society stage 1 or 2 chondral lesions. Preoperatively, the objective IKDC grades were B in 4 patients, C in 5, and D in 3. After surgery, the IKDC grades were A in 4 patients, B in 7, and grade C in 1. The mean subjective IKDC and Lysholm scores were a respective 43.4 ± 8.4 and 55.7 ± 12.4 preoperatively and 83.8 ± 9.4 and 93.2 ± 9.0 at the final follow-up ( P < .05). Ten patients (83%) reported recovery of sports activities, with 6 patients (50%) reaching the same level as before injury. The mean ACL-RSI score was 76.2%. Preoperatively, 50% (n = 6) of patients had Ahlbäck stage 1 medial compartment arthritis, versus 58% (n = 7) at the final follow-up ( P = nonsignificant). The side-to-side difference in anterior tibial translation on stress radiographs was 7.2 ± 6.4 mm preoperatively and 1.9 ± 4.3 mm postoperatively ( P < .05). No major complications were reported. Conclusion: ACL reconstruction in active patients older than 60 years without arthritis restored knee stability in all treated cases. In these patients, as in younger age groups, ACL reconstruction showed good results on functional recovery while not increasing the risk of midterm functional knee deterioration or evolution of knee arthritis. The majority of patients returned to activities at their preinjury level. These data show that older and active patients with nonarthritic ACL-deficient knees need not be excluded from surgical treatment.

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.

Abstract Introduction: Anterior cruciate ligament (ACL) rupture is one of the most common lesions in knee traumatology; therefore the number of ACL reconstructions is increasing worldwide. Usually, an anteromedial (AM) accessory portal is required in anatomical positioning of the femoral tunnel, which is not absolutely necessary in this technique. Aim: Assessment of all-inside ACL reconstruction preliminary clinical results with adjustable loops and buttons on both femoral and tibial surfaces. Method: Our prospective study included 28 subjects (19 male, 9 female) with chronic ACL ruptures. The mean age of the study population was 27.72 ± 8.23 years. In all cases ACL reconstruction was carried out with the use of quadrupled semitendinosus auto-grafts with adjustable loops and buttons on the femoral and tibial surfaces and anatomic placement of both tunnels, using an outside-in technique, with flipcutters (Arthrex®). Clinical and radiological evaluations were carried out before surgery and at 3 and 6 months postoperatively, with the Lysholm scoring system, the Tegner activity scale and anterior-posterior and latero-lateral X-rays. Anterior knee laxity was measured in 25° of flexion using a portable arthrometer (RolimeterTM, Aircast®) and maximum manual force. Results: During the final follow-up, the Lysholm score was good and excellent in 27 cases, with a mean Lysholm score of 95.55 ± 4.63; all results were classified as good. The mean preoperative Tegner activity score was 3.46 ± 1.71 (range: 1-7), and the post-operative mean score was 5.75 ± 2.24 (range: 2-10). We found no graft ruptures. Preoperative knee laxity measurements showed a mean displacement of 11.5 ± 3.1 mm and side-to-side differences of 5.6 ± 3.5 mm, while the postoperative measurements at the last follow-up were 6.3 ± 1.54 mm and 2.65 ± 1.86 mm, respectively. Conclusion: Short-term clinical outcomes of all-inside ACL restoration with anatomic placement femoral and tibial tunnels seem to recommend this surgical option, with good subjective and objective results. Additional research will have to prove the long-term success.

AbstractThe aim of the study is to compare the tear rates of ipsilateral anterior cruciate ligament (ACL) grafts and the contralateral native ACL as well as to investigate the correlation of gender, age at time of surgery, and body mass index (BMI) with the occurrence of these injuries. The medical records of 751 patients who underwent ACL reconstruction surgery with follow-up periods of 2 to 7 years were retrospectively analyzed. Survival analyses of ipsilateral ACL grafts and contralateral native ACL were performed. Univariate and multivariate logistic regression analyses were performed to identify risk factors that were associated with these injuries. The tear rates of the ipsilateral ACL graft and contralateral ACL were 5.86 and 6.66%, respectively with no significant difference between groups (p = 0.998). The mean time of tears of the ipsilateral ACL and contralateral ACL was also similar (p = 0.977) at 2.64 and 2.78 years, respectively after surgery. Both the odds of sustaining an ipsilateral ACL graft and contralateral ACL tear were also significantly decreased by 0.10 (p = 0.003) and 0.14 (p = 0.000), respectively, for every 1-year increase in age at which the reconstruction was performed. However, graft type, gender, and BMI were not associated with an increased risk of these injuries. There was no difference between tear rates of ipsilateral ACL graft and contralateral ACL following ACL reconstruction. Patients who undergo ACL reconstruction at a young age are at an increased risk of both ipsilateral graft and contralateral ACL rupture after an ACL reconstruction. Patients who are young and more likely to return to competitive sports should be counselled of the risks and advised to not neglect the rehabilitation of the contralateral knee during the immediate and back to sports period of recovery. This is a Level III, retrospective cohort study.

Purpose To evaluate the 5-year outcome of arthroscopic transphyseal anterior cruciate ligament (ACL) reconstruction in 19 adolescent athletes. Methods 14 male and 5 female adolescent athletes aged 12 to 16 (mean, 13.9) years with Tanner stage 2 or 3 open physes underwent arthroscopic transphyseal ACL reconstruction by a single surgeon and were followed up for 5 years. Patients were evaluated using the numerical rating score (NRS) for pain, knee osteoarthritis outcome score (KOOS), International Knee Documentation Committee (IKDC) score, Tegner Activity Scale, and Lysholm Score, as well as the leg length discrepancy, femorotibial alignment, varus or valgus deformities, active and passive knee range of motion. Results At 5-year follow-up, physes were closed in all patients. The mean NRS for pain improved from 7.2 to 1.6; the KOOS improved from 55.3 to 88; the mean IKDC score improved from 34.5 to 84; the mean Tegner Activity Scale improved from 2.7 to 8.2 and was comparable with that before injury (8.4); and the mean Lysholm score improved from 36.3 to 84.6. All except 2 patients returned to their pre-injury level of sports activity after a mean of 25 weeks. The 2 exceptions had a 2+ Jerk test and a 3+ Lachman test; one of them also had positive signs for a lateral meniscal lesion. Both had sustained a second trauma not long before the 5-year follow-up. Two patients had reduced sensitivity in the anteromedial aspect of the proximal third of the tibia. One patient had leg length discrepancy of +1.5 cm owing to overgrowth response of the physis. Conclusion Transphyseal ACL reconstruction is a viable option for skeletally immature patients, with high reproducibility, a high rate of return to sport, and a low incidence of growth disturbance. Early surgery can prevent the onset of meniscal lesions and early osteoarthritis.

Double Bundle Acl Reconstruction

Background: A long-term follow-up comparing double-bundle and single-bundle techniques for anterior cruciate ligament (ACL) reconstruction has not been reported before. Hypothesis: Double-bundle ACL reconstruction may have fewer graft ruptures, lower rates of osteoarthritis (OA), and better stability than single-bundle reconstruction. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Ninety patients were randomized for double-bundle ACL reconstruction with bioabsorbable screw fixation (DB group; n = 30), single-bundle ACL reconstruction with bioabsorbable screw fixation (SBB group; n = 30), and single-bundle ACL reconstruction with metallic screw fixation (SBM group; n = 30). Evaluation methods consisted of a clinical examination, KT-1000 arthrometer measurements, International Knee Documentation Committee (IKDC) and Lysholm knee scores, and a radiographic examination of both the operated and contralateral knees. Results: Eighty-one patients (90%) were available at the 10-year follow-up. Eleven patients (1 in the DB group, 7 in the SBB group, and 3 in the SBM group) had a graft failure during the follow-up and went on to undergo revision ACL surgery ( P = .043). In the remaining 70 patients at 10 years, no significant group differences were found in the pivot-shift test findings, KT-1000 arthrometer measurements, or knee scores. The most OA findings were found in the medial compartment of the knee, with 38% of the patients in the operated knee and 28% of the patients in the contralateral nonoperated knee. However, no significant group difference was found. The most severe OA changes were in the patients who had the longest delay from the primary injury to ACL reconstruction ( P = .047) and in the patients who underwent partial meniscal resection at the time of ACL reconstruction ( P = .024). Conclusion: Double-bundle ACL reconstruction resulted in significantly fewer graft failures than single-bundle ACL reconstruction during the follow-up. Knee stability and OA rates were similar at 10 years. The most severe OA changes were found in the patients who had the longest delay from the primary injury to ACL reconstruction and in the patients who underwent partial meniscal resection at the time of ACL reconstruction.

Objectives: The Associated Extra-Articular Technique (AET) with Lateral Tenodesis (LT) to the current techniques of intra-articular reconstruction of the Anterior Cruciate Ligament (ACL) could potentially improve the laxity of the knee and act synergically in controlling the phenomenon of the pivot displacement in cases of severe rotational instability. Methods: Twenty-two consecutive patients were selected who met all the inclusion criteria and underwent reconstruction of the ACL with double bundle and AET between February 2012 and May 2013. The inclusion criteria in this study was the presence of moderate to severe rotational instability as revealed by a score of pivot test of 2 to 3 (on a scale ranging from 0 = negative, to 3 = subluxation). The least time between trauma and surgery was 3 months, and average age under 40 years old. Results: The mean time of follow-up was 32.4 ± 3.9 months. In all cases, the Lysholm and IKDC test scores improved significantly (p <0.0001). The differential laxity above the average was 8 ± 1.9 mm before surgery and significantly reduced to 0.7 ± 0.8 mm at the last follow-up (p <0.0001). Prior to surgery, patients had a Grade 3 Pivot Shift according to the IKDC criteria. After surgery, 15 patients had turned to a negative Pivot (Grade 0), and 7 patients were Grade 1. Conclusion: The lateral extra-articular reconstruction is generally used to control the internal rotation laxity of the tibia, and we are convinced that the combination of the LT with the reconstruction of the double bundle LCA would reduce the rotational translation during the pivot test.

Anterior Cruciate

AbstractSingle-bundle (SB) anterior cruciate ligament (ACL) reconstruction is increasingly used in a large number of patients and it allows obtaining very good clinical and subjective results; however, functional tests show a persistent rotational instability. Biomechanical studies seem to indicate that double-bundle (DB) ACL reconstruction allows to obtain increased anterior and rotational stability compared with SB. The aim of this prospective randomized controlled study was to compare the clinical outcome and the possible osteoarthritic evolution of patients treated either with a SB (freehand transtibial femoral tunnel) or with a DB technique (outside-in for posterolateral femoral tunnel/inside-out for anteromedial femoral tunnel) at a final follow-up of 6 years. A total of 60 patients with complete ACL rupture (age, 16–40 years) were prospectively randomized to SB (n = 30) or DB (n = 30) groups. Patients were evaluated preoperatively and after surgery at 6 months, 1, 3, and 6 years with Lysholm score, International Knee Documentation Committee (IKDC) form, and KT-2000 (Medmetric Corp). The degree of osteoarthritis (OA) based on the Kellgren–Lawrence grade was also assessed. No significant differences in background factors between the two groups were observed. Homogeneity was also found in term of preoperative Lysholm score, IKDC, and KT-2000 between SB and DB groups. After 6 months from surgery, both groups showed significant improvements for Lysholm, IKDC, and KT-2000 score with respect to preoperative observations (p < 0.001); however, no significant differences have been observed in term of postoperative values between SB and DB groups at each time point (6-year evaluation: Lysholm score 98.14 ± 10.03 and 97.22 ± 12.82; IKDC normal + nearly normal 95 and 100%; KT-2000 1.68 ± 1.26 and 1.03 ± 1.92 for SB and DB, respectively; all p > 0.05). At the final follow-up, three patients (11.11%) in the DB group and two patients (7.69%) in the SB group presented signs of OA progression. Our study did not reveal any advantages in using DB ACL reconstruction in mid- to long-term follow-up in term of clinical outcome and knee stability, as well as in term of OA progression.
