Abstract Purpose Reconstruction of the Anterior cruciate ligament (ACL) using tendon grafting is an established method for restoring knee function and stability. Multiple methods are established for graft fixation. Several involve anchoring the autograft distant to the joint with hardware that remains implanted. This study reports the first early to midterm results in patients who received ACL reconstruction (ACLR) using the T-Lock Osteotrans femoral near joint fixation method with a tibial fixation using the BioactIF Osteotrans interference screw. Methods This consecutive prospective series included 20 Patients (14 Male, 6 Female) with a primary ACL rupture. All patients were treated with an ACLR using a semitendinosus autograft fixated with the T-Lock Osteotrans and were followed-up postoperatively. The following parameters were assessed: Side-to-side difference of the posterior-anterior translation measured using the KT-1000 arthrometer, Tegner activity score, Lysholm score, IKDC subjective knee evaluation form. Magnetic resonance imaging (MRI) was done to assess tunnel enlargement and integrity of the anchoring device. Results The average follow-up duration was 2 years (range 1–4.2 years). One patient was lost to follow-up. Two Patients suffered a traumatic ACL re-rupture 2 years postoperatively and received a 2-stage revision ACLR. Difference in the posterior-anterior translation was 1.8 mm (range 0–5). The median Tegner score was 6 (range 4–10) and 9 patients (45%) returned to their preinjury level of activity. The mean IKDC subjective knee evaluation form scored 91 points (range 77–100). The mean Lysholm score was 86 points (74–96). All mentioned scores were significantly better compared to preoperative values. No relevant tunnel enlargement was seen on MRI. The anchoring device was evaluated to be intact in all patients. Conclusion ACLR with the aforementioned procedure leads to good clinical and radiological outcome.

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.

Abstract Evaluating the early clinical results of anterior cruciate ligament reconstruction using hamstrings autograft, with interference screw on the tibial side (biocomposite interference screw, ConMed-Linvatec) and continuous closed loop fixation on the femoral side (XO-Button, ConMed-Linvatec), with and without intra-articular injection of autologous conditioned plasma (ACP). Our study included 21 patients with chronic anterior cruciate ligament (ACL) ruptures for whom we performed ACL reconstruction with a hamstrings autograft. The mean age was 34 years (range, 25 to 42), 16 patients were men and 5 were women. In 10 cases we performed an intraarticular infiltration of ACP at the end of the surgical intervention. Final evaluation was performed at the end of the 6th postoperative month using the Lysholm scoring system, Tegner activity scale and objective assessment with the RolimeterTM 50A. The Lysholm score was excellent in all cases at 6 months postoperatively, with a mean Lysholm score of 90 for patients without ACP and 91.09 for patients that received ACP; the mean Tegner activity score was also similar pre- and postoperatively for the two groups (from 3.5 and 3.63 for the group without ACP and the group with ACP to 5.6 and 5.72 respectively). Joint laxity measurement was similar for both groups. We found no graft ruptures. We found similar results after ACL reconstruction with and without intra-articular injection of PRP, but further studies are necessary to determine the exact role of these substances in speeding up the recovery process in these cases.

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.

Tendon Autograft

Background: Hamstring tendons are widely used in anterior cruciate ligament reconstruction. Improvements in fixation materials have increased the success of the reconstruction procedures using this type of graft. The main advantage of the hamstring tendon autograft is the lower donor site morbidity associated with its harvesting. On the other hand, tunnel widening is reported more frequently with the use of hamstring tendon autograft compared to patellar or quadriceps tendons. The objective of the present study was to evaluate three different fixation techniques at a minimum of 2 years after Anterior Cruciate Ligament (ACL) reconstruction using gracilis and semitendinosus autograft. Methods: Between February 2012 and March 2016, 112 ACL reconstructions using double looped semitendinosus and gracilis graft were performed. Patients were divided into 3 groups in a randomized fashion. 98 patients were followed up for 2 years. In the first group (43 patients), suspensory fixation using Retrobutton (Arthrex, Inc, Naples, Florida) was used. In the second group (30 patients), transcondylar graft fixation Bio-Transfix (Arthrex, Naples, Florida) was performed, and in the third group (25 patients), aperture fixation using AperFix (Cayenne Medical, Scottdale, Arizona, Biomet) was performed. Clinical evaluation was performed using the International Knee Documentation Committee (IKDC) form, Lysholm knee and Tegner activity level scores, as well as arthometer measurements. Tunnel enlargement and graft integrity were evaluated using Magnetic Resonance Imaging (MRI) at 6, 12 and 24 months. Results: Ten patients were completely lost to follow up, and four had undergone a revision ACL reconstruction before the two-year follow up period, leaving 98 patients for analysis. No statistically significant differences between the three groups were noted other than that the first group tended to have more tunnel enlargement than the other two groups, especially at the femoral tunnel (p=.026), but not at the tibial tunnel (p>0.408). Our results showed that almost 90% of the patients in the three groups had functionally normal or near normal IKDC, Lysholm and Tegner scores. Conclusion: The three different techniques yielded equal results as regards improved patient performance. The functional results as well as knee stability tests were not related with tunnel enlargement, at least in the short term.

Background: Anterior cruciate ligament reconstruction (ACLR) is a common orthopaedic sports medicine procedure, but graft failure is not uncommon and often leads to revision ACLR. Revision surgery can be performed in a 1- or 2-stage fashion. Hypothesis: Graft failure risk, patient-reported outcomes, and anterior knee laxity are similar after 1- and 2-stage revision ACLR. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic review of the literature was performed to evaluate patient outcomes after 1- versus 2-stage revision ACLR. A search was performed with the phrase “revision anterior cruciate ligament reconstruction” across Embase, PubMed, Scopus, and SportDiscus from the beginning of their archives through July 12, 2019. Results: Thirteen studies met inclusion criteria and included 524 patients: 319 patients who underwent 1-stage revision ACLR and 205 patients who underwent 2-stage revision ACLR. Two studies compared outcomes of 1- versus 2-stage revision ACLR; 4 studies reported outcomes after 2-stage revision ACLR; and the remaining 7 studies documented outcomes after 1-stage ACLR. The mean follow-up was 4.1 years. The 2 studies that compared 1- versus 2-stage ACLR reported no differences in functional, radiologic, or patient-reported outcomes or failure risk. Overall, 9 studies reported subjective International Knee Documentation Committee (IKDC) scores; 4 studies, Knee injury and Osteoarthritis Outcome Score values; 8 studies, Lysholm scores; and 7 studies, Tegner scores; 8 studies measured anterior laxity with a KT-1000 arthrometer. The mean weighted subjective IKDC score for all studies including this outcome at final follow-up was 66.6 for 1-stage revisions and 65.9 for 2-stage revisions. Conclusion: The available evidence comparing 1- versus 2-stage revision ACLR is retrospective and limited. The results of each approach are similar in appropriately selected patients.

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.

In this study we reported the early clinical and functional results of 40 patients admitted to our hospital for anterior cruciate ligament reconstruction (20 with autogenous hamstring tendon graft and 20 with peroneus longus allograft)retrospectively between august 2012 and september 2014. All patients in the autograft group were male and only three patients in the allograft group were female. The mean age in the autograft group was 29,60±4,55 and 34,25±6,73 in the allograft group. The mean time period before the surgery was 10,35(1-84) months and the mean postoperative follow up time was 33,8(12-46) months. Only 2 patients in the autograft group and 4 patients in the allograft group were injured by direct trauma. We noted the patients’ occupation, activity level and sport activities. Joint effusion, pain and restriction in the joint motion were documented. Patients were evaluated with Lachman, anterior drawer and pivot shift tests at the last follow up examination. The joint instability was tested with KT 1000 and the muscle contractions were tested with Cybex devices. Modified Cincinnati, Lysholm and IKDC activity scale were used to evaluate the activity level of patients. There were no difference neither clinically, nor functionally between two groups at the last follow up (p>0,05).Taken into consideration the risks and advantages of autogenous hamstring graft and allograft use we conclude that the peroneus longus allograft is a reasonable option for anterior cruciate ligament reconstruction.

Abstract Objective Rupture of the anterior cruciate ligament (ACL) in childhood and adolescence is a serious injury. It is now known that conservative therapy of an unstable knee joint in childhood or adolescence under can lead to poor subjective and objective results. The aim of this study is to record long-term results after transepiphyseal ACL reconstruction using autologous hamstring tendons and extracortical fixation in childhood and adolescence with open physes – at least 15 years after surgery. Methods Our internal registry was used to identify all patients who received surgical treatment of an acl tear during childhood and adolescence by transepiphyseal acl reconstruction more than 15 years previously. In these patients, the International Knee Documentation Committee for Subjective Knee Form (IKDCsubj.), Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Score (TAS) and Lysholm Score were collected, and clinical and magnetic resonance imaging (MRI) examinations were performed. Results A total of 22 patients were identified, 5 of whom could not be contacted. The mean age at the time of surgery was 13.1 years, and the mean follow-up time was 17.4 years. In 3 patients, a traumatic tear was observed with subsequent reconstruction of the ACL. None of the included patients showed a growth disorder during the course of the study. The IKDCsubj. was 92.4 ± 14.7 (48 – 100), the Lysholm score was 87.9 ± 16.9 (34 – 100), the TAS was 5.7 ± 2.3 (3 – 9) and the pain level based on VAS was 3.5 ± 2.6 (1 – 8) points. The values showed subjective and objective deterioration compared to the 10-year results, with no statistical significance. The following subscores were reported for the KOOS: KOOSpain 90.9 ± 17.6 (28 – 100); KOOSsymptom 82.9 ± 22.6 (11 – 100); KOOOSADL 94.3 ± 13.7 (44 – 100); KOOSSport 80.3 ± 26.4 (15 – 100); KOOSQOL 80.9 ± 25.8 (0 – 100). 13 of the 17 patients could also be clinically and radiologically examined. In 92% of patients, an intact acl reconstruction was found without evidence of cartilage or meniscus damage. The mean lateral difference in the KT-1000 measurement was 1.5 mm. Conclusion ACL reconstruction in childhood and adolescence provides good functionality and stability of the knee joint over the long term. Secondary signs of osteoarthritis can only be detected in isolated cases by MRI. ACL reconstruction using the transepiphyseal technique can be considered the method of choice for open growth plate knee joints.
