EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:67-73. [PMID: 37644333 PMCID: PMC10771374 DOI: 10.1007/s00590-023-03698-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Accepted: 08/17/2023] [Indexed: 08/31/2023]
Abstract
PURPOSE Evaluate the outcomes of ACL (Anterior Cruciate Ligament) reconstruction techniques that use a hamstring graft with a preserved tibial insertion and compare them to standard techniques. METHODS A systematic literature review and meta-analysis was done of the PubMed, MEDLINE, Cochrane and Ovid databases to identify published clinical studies on ACL reconstruction in which a non-detached hamstring tendon (NDHT) was used as a graft and to compare them to studies in which a detached hamstring tendon (DHT) or other techniques were used. The eligible studies were analyzed for the knee laxity, Lachman test, pivot shift test, joint range of motion, anterior drawer, pain, re-tear, revision surgery, Lysholm score, Tegner score, ACL-RSI scale, KOOS, IKDC, SNQ and Howell scale. RESULTS Twelve articles in which NDHT was used for ACL reconstruction were analyzed. There was no significant difference between NDHT and DHT in the Lachman > 1 (p = .07), pivot shift test > 1 (p = .40), re-tears (p = .62), pain (p = .85) and the Tegner score (p = .95). However, the outcomes were somewhat better with the NDHT technique for the Lachman (RR = 0.30; 95% CI 0.08-1.12), pivot shift test (RR = 0.50; 95% CI 0.10-2.49) and re-tears (RR = 0.66; 95% CI 0.13-3.42). The other criteria were not included in the meta-analysis because of lack of data or because specific outcome scores were used in each article. CONCLUSION NDHT techniques provide similar results to DHT for ACL reconstruction and tend to produce better stability and a lower re-tear rate.

Orthop Traumatol Surg Res 2023; 109:103556.

Abstract
INTRODUCTION The hamstring tendons (gracilis and semitendinosus) are often used as an autograft for anterior cruciate ligament (ACL) reconstruction. Healing of this graft involves a slow biological process called ligamentization. To encourage this process, some authors have proposed preserving the insertion of the hamstring tendons. HYPOTHESIS Leaving the tibial insertion of the hamstring tendons intact will provide better early biological incorporation and superior tibial mechanical fixation resulting in various clinical advantages. MATERIALS AND METHODS In January 2022, a systematic literature review was carried out independently by two authors of the Medline, PubMed and Embase databases. The keywords used were "pedicular" or "pedicled" or "preservation of tibial attachment" or "hamstring tibial insertion" AND "ACL reconstruction". Each author's data was analyzed separately. RESULTS Sixteen articles were analyzed. Preserving the hamstring tibial insertion during ACL reconstruction improves the graft's biological incorporation during the initial postoperative phase according to clinical studies with MRI analysis and provides a mechanical advantage at the graft's tibial attachment according to biomechanical studies (construct up to 65% stiffer). There was no difference in the clinical and functional scores when compared to the conventional technique in which the hamstring tendons are detached from their tibial insertion. DISCUSSION The main conclusion of this systematic literature review was that preserving the hamstring tibial insertion during ACL reconstruction appears to improve the graft's ligamentization with biological and mechanical advantages relative to detaching the hamstring tendons. The clinical and functional results were comparable to other techniques. Prospective studies with large cohorts are still needed to confirm these findings.

Abstract
BACKGROUND The semitendinosus (ST) tendon can be used by itself as a graft for anterior cruciate ligament (ACL) reconstruction. An increasing number of these procedures are being done while preserving the ST's tibial attachment, but there are no data on the remodeling of an attached ST (aST) graft. PURPOSE To compare graft remodeling on magnetic resonance imaging (MRI) scans at 1 year after ACL reconstruction between standard free ST graft and aST graft. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS This prospective study enrolled 180 patients who were undergoing ACL reconstruction: 90 with the ST graft and 90 with the aST graft. The analysis was performed 1 year after the surgery. The main endpoint was the signal-to-noise quotient (SNQ) on MRI scans (T1-weighted sequence). The secondary endpoints were tibial tunnel widening (TTW), graft maturation (Howell classification), retear rate, new surgery rate, Simple Knee Value, Lysholm score, International Knee Documentation Committee (IKDC) score, postoperative Tegner score, difference between pre- and postoperative Tegner scores, ACL-Return to Sport after Injury (ACL-RSI), return-to-sports rate, and time to return to sports. RESULTS The mean adjusted SNQ was 1.18 (95% CI, 0.72-1.65) in the aST group and 3.88 (95% CI, 3.42-4.34) in the ST group (P < .001). The new surgery rate was 2.2% in the aST group and 10% in the ST group (P = .029). The median Lysholm score was significantly higher in the aST group (99; interquartile range [IQR], 95-100) than in the ST group (95; IQR, 91-99) (P = .004). The mean time to return to sports was significantly shorter in the aST group (248.73 ± 141.62 days) than the ST group (317.23 ± 144.69 days) (P = .002). No statistically significant difference was found between groups in the TTW (P = .503), Howell graft maturity grade (P = .149), retear rate (P > .999), Simple Knee Value (P = .061), postoperative Tegner score (P = .320), pre- to postoperative difference in Tegner score (P = .317), ACL-RSI (P = .097), IKDC score (P = .621), and return-to-sports rate (P > .999). CONCLUSION At 1 year postoperatively, remodeling of an ST graft assessed using MRI is better when its distal attachment is left intact.

Changes in Macrophage Polarization During Tendon-to-Bone Healing After ACL Reconstruction With Insertion-Preserved Hamstring Tendon: Results in a Rabbit Model. Orthop J Sports Med 2022; 10:23259671221090894. [PMID: 35620112 PMCID: PMC9128061 DOI: 10.1177/23259671221090894] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Accepted: 01/21/2022] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Decreasing the proinflammatory M1 macrophages or shifting the polarization status from M1 to M2 phenotype is thought to be beneficial for tendon-to-bone healing. In anterior cruciate ligament reconstruction (ACLR), using an insertion-preserved hamstring tendon (IP-HT) graft compared with a free hamstring tendon (FHT) graft has been shown to reduce graft necrosis and improve healing. However, the role of macrophage polarization at the tendon-to-bone interface is unclear. HYPOTHESIS ACLR using IP-HT graft would facilitate the phenotype shift from M1 to M2 macrophages at the tendon-to-bone interface. STUDY DESIGN Controlled laboratory study. METHODS Unilateral ACLR was performed on 42 healthy New Zealand White rabbits (study group, 21 rabbits with IP-HT graft; control group, 21 rabbits with FHT graft). At days 1, 3, and 7 and weeks 3, 6, 12, and 24 postoperatively, 3 rabbits in each group were sacrificed to investigate and compare the expression of surrogate markers for M1 macrophages (inducible nitric oxide synthase [iNOS] and tumor necrosis factor α [TNF-α]) and M2 macrophages (CD206 and transforming growth factor β [TGF-β]) via immunohistochemical staining and evaluation. RESULTS In the control group, the percentage of iNOS- and TNF-α-positive cells from postoperative day 7 and week 3 increased then decreased by week 6; positive expression of CD206 and TGF-β was weaker and peaked at 3 weeks postoperatively. In the study group, high CD206- and TGF-β-positive expression was observed from weeks 3 to 12 and peaked at week 6, and positive expression of iNOS- and TNF-α was weaker and peaked on day 7. At both 7 days and 3 weeks, the percentages of iNOS- and TNF-α-positive cells in the control group were both significantly higher than in the study group (P ≤ .04 for all). At 6 weeks, the percentages of CD206- and TGF-β-positive cells in the study group were both significantly higher than in the control group (P = .02 and P = .04, respectively). CONCLUSION More expression of surrogate markers for M2 macrophages was observed in the tendon-to-bone healing process after ACLR using IP-HT versus FTP graft. CLINICAL RELEVANCE Using IP-HT grafts in ACLR may facilitate postoperative healing by shifting the local status of macrophage polarization at the tendon-to-bone interface.

Abstract
BACKGROUND There is an ongoing debate on the treatment of bursal-sided partial-thickness rotator cuff tears (PTRCTs), including ideal repair techniques. Augmentation using a collagen patch has been introduced as a new surgical approach to treat PTRCTs, while the effect of autogenous biceps augmentation (BA) has not been investigated. PURPOSE To analyze the effects of BA on bursal-sided PTRCTs and compare its histological and biomechanical results with those of tear completion followed by repair and in situ repair (ISR). STUDY DESIGN Controlled laboratory study. METHODS Unilateral chronic PTRCTs were created in 96 mature New Zealand White rabbits, which were randomly divided into 4 groups: no repair, tear completion repair (TCR), ISR, and BA. A new bicipital groove was fabricated in BA for the biceps tendon that was transferred to augment the bursal-sided PTRCT repair. In each group, we sacrificed 6 rabbits for biomechanical testing of the whole tendon-to-bone complex (WTBC) and 6 for histological evaluation of bursal- and articular-sided layers at 6 and 12 weeks postoperatively. Healing responses between the biceps and new bicipital groove in the BA group were determined using histological analysis, and final groove morphologies were evaluated using micro-computed tomography. RESULTS The remaining tendon and enthesis in bursal-sided PTRCTs progressively degenerated over time. WTBCs of ISR exhibited a larger failure load than those of TCR, although better healing properties in the bursal-sided repaired site were achieved using TCR based on histological scores and superior articular-sided histological scores were observed using ISR. However, WTBCs of BA displayed the best biomechanical results and superior histological scores for bursal- and articular-sided regions. The new bicipital groove in BA remodeled over time and formed similar morphologies to a native groove, which provided a mature bone bed for transferred biceps tendon healing to augment bursal-sided PTRCTs. CONCLUSION BA achieved better biomechanical and histological results for repairing bursal-sided PTRCTs as compared with TCR and ISR. When compared with that of TCR, the WTBC of ISR exhibited a higher failure load, showing histological superiority in the articular-sided repair and inferiority in the bursal-sided repair. CLINICAL RELEVANCE BA may be an approach to improve bursal-sided PTRCT repair in humans, which warrants further clinical investigation.

Abstract
Background Bone formation plays an important role in early tendon–bone healing after anterior cruciate ligament reconstruction (ACLR). Dedifferentiated osteogenic bone marrow mesenchymal stem cells (De-BMSCs) have enhanced osteogenic potential. This study aimed to investigate the effect of De-BMSCs transplantation on the promotion of bone formation at the tendon–bone interface after ACLR and to further explore the molecular mechanism of the enhanced osteogenic potential of De-BMSCs. Methods BMSCs from the femurs and tibias of New Zealand white rabbits were subjected to osteogenic induction and then cultured in medium without osteogenic factors; the obtained cell population was termed De-BMSCs. De-BMSCs were induced to undergo osteo-, chondro- and adipo-differentiation in vitro to examine the characteristics of primitive stem cells. An ACLR model with a semitendinosus tendon was established in rabbits, and the animals were divided into a control group, BMSCs group, and De-BMSCs group. At 12 weeks after surgery, the rabbits in each group were sacrificed to evaluate tendon–bone healing by histologic staining, micro-computed tomography (micro-CT) examination, and biomechanical testing. During osteogenic differentiation of De-BMSCs, an siRNA targeting nuclear factor of activated T-cells 1 (NFATc1) was used to verify the molecular mechanism of the enhanced osteogenic potential of De-BMSCs. Results De-BMSCs exhibited some properties similar to BMSCs, including multiple differentiation potential and cell surface markers. Bone formation at the tendon–bone interface in the De-BMSCs group was significantly increased, and biomechanical strength was significantly improved. During the osteogenic differentiation of De-BMSCs, the expression of Nanog and NFATc1 was synergistically increased, which promoted the interaction of NFATc1 and Osterix, resulting in increased expression of osteoblast marker genes such as COL1A, OCN, and OPN. Conclusions De-BMSCs transplantation could promote bone formation at the tendon–bone interface after ACLR and improve the biomechanical strength of the reconstruction. The Nanog/NFATc1/Osterix signaling pathway mediated the enhanced osteogenic differentiation efficiency of De-BMSCs.

Abstract
Background Preservation of hamstring tendon insertion at the time of anterior cruciate ligament (ACL) reconstruction is a well-known technique; however, its effect on graft integration is not well studied. The present study was conducted to study the graft integration inside the tibial and femoral tunnels, respectively, after ACL reconstruction using hamstring tendon graft with preserved insertion. Methods Twenty-five professional athletes who underwent ACL reconstruction using hamstring tendon graft with preserved tibia insertion were enrolled in the study. Functional outcomes were checked at final follow-up using Lysholm score and Tegner activity scale. Magnetic resonance imaging (MRI) was done at 8 months and 14 months follow-up to study the graft tunnel integration of the ACL graft at both tibial and femoral tunnels. Results The mean Fibrous interzone (FI) score (tibial tunnel) decreased from 2.61 (1–5) at 8 months to 2.04 (1–4) at 14 months follow-up (p = 0.02). The mean FI score (femoral side) decreased from 3.04 (2–5) at 8 months to 2.57 (2–4) at 14 months (p = 0.02). Conclusions Graft integration occurs early in the tibial tunnel as compared with the femur tunnel with preserved insertion hamstring tendon autograft.

Abstract
BACKGROUND It has been reported that insertion-preserved hamstring tendon autografts (IP-HT) have better maturity than free hamstring tendon autografts (FHT) at 2 years after anterior cruciate ligament reconstruction (ACLR); however, whether insertion preservation improves the maturity of the entire autograft and clinical outcomes at 5 years after ACLR is still unclear. PURPOSE To investigate the clinical outcomes and maturity of different segments using insertion-preserved and free hamstring tendon autografts up to 5 years after ACLR. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS 45 patients who underwent isolated ACLR with hamstring tendon autografts were enrolled and randomized into 2 groups. The study group had ACLR with IP-HT, whereas the control group had ACLR with FHT. The International Knee Documentation Committee and Tegner scores, Lysholm activity score, and KT-1000 arthrometer measurements were evaluated preoperatively and at 6, 12, 24, and 60 months postoperatively. Three-dimensional-reconstruction MRI examinations were performed at 6, 12, 24, and 60 months to evaluate the signal/noise quotient (SNQ) values of femoral tunnel graft, intra-articular graft, and tibial tunnel graft. RESULTS At 60 months, the SNQ values of the intra-articular and tunnel sections for the grafts in both groups showed no difference; the clinical outcomes were improved compared with before surgery (P < .001) and were similar in both groups. In the early stage, all graft segments in the IP-HT group had lower SNQ values than those of the FHT group. At 6 months, the entire graft in the FHT group and the femoral tunnel section in the IP-HT group had the maximum SNQ values, whereas the femoral tunnel graft had the highest SNQ value compared with intra-articular and tibial tunnel graft in each group. SNQ values of the intra-articular and tibial tunnel graft in the IP-HT group had no significant change within 60 months. CONCLUSION All patients had similar clinical outcomes and graft maturity at 60 months postoperatively. The SNQ values and progressions varied at different graft sites and were highest for the femoral tunnel graft. All significantly changing SNQ values reached the maximum value at 6 months. Compared with FHT autograft, the graft maturity of IP-HT autograft recovered earlier and appeared more stable within the 60-month follow-up; however, no significant association was found between graft maturity and clinical scores.

Abstract
PURPOSE The aim of this study was to introduce a modified anatomical anterior cruciate ligament reconstruction using functional double bundles (F-DBACLR), which achieved sequential tensioning at all flexion angles postoperatively, and compare its clinical outcomes with the anatomical single-bundle technique (A-SBACLR). METHODS A total of 156 patients with an ACL injury underwent ACLR (A-SB group, n = 78; F-DB group, n = 78). All operations were performed by anatomically identifying the ACL footprints and fixing the graft at a pre-determined degree of knee flexion. Two observers blinded to the patient identities examined the patients preoperatively and during follow-up (median 28.2 months; range 26-31 months). Multiple subjective and objective clinical evaluation tests and assessment of clinical outcomes concerning the translational and rotational stability of the knee including the International Knee Documentation Committee (IKDC) questionnaire, Lysholm Knee Scoring Scale, Knee Injury and Osteoarthritis Outcome Score (KOOS), Tegner Activity Scale, KT-1000 laxity measurements, Lachman test and pivot-shift test were performed preoperatively and postoperatively. RESULTS Preoperatively, no differences were found between the two groups. During the 2-year observation period, patients in the F-DB group revealed better clinical outcomes in terms of the Tegner Activity Scale Score, IKDC, KOOS and Lysholm Knee Scoring Scale. Similar results were shown in regard to the translational stability in both groups, while the F-DB group had more rotational stability at 2 years of follow-up. CONCLUSIONS The clinical outcomes indicated that F-DBACLR is clinically practicable and advantageous in the treatment of the ACL-deficient knee. LEVEL OF EVIDENCE II.

Abstract
BACKGROUND The semitendinosus tendon graft with an intact tibial insertion has a sustainable blood supply and might be beneficial for graft maturation after anterior cruciate ligament reconstruction (ACLR); however, its potential advantages for graft tendon-bone healing is still unclear. HYPOTHESIS Intact tibial insertion of the hamstring tendon can preserve enough blood supply to keep the harvested tendon alive, which can improve tendon-bone healing and the biomechanical strength of the graft. STUDY DESIGN Controlled laboratory study. METHODS Sixty-four healthy New Zealand White rabbits underwent unilateral ACLR with a semitendinosus tendon autograft after random enrollment into 2 groups (study group, n = 32 rabbits with semitendinosus tendon-preserved tibial insertions; control group, n = 32 rabbits with free semitendinosus tendons). At weeks 3, 6, 12, and 24, 8 rabbits in each group were sacrificed to evaluate tendon-bone healing by histologic staining, micro-computed tomography (micro-CT) examination, and biomechanical test. RESULTS The grafts in the study group maintained a similar cell count with no signs of necrosis or hypocellularity across all time points, but the grafts in the control group underwent a characteristic stage of necrosis at weeks 3 and 6. Sharpey-like fibers were observed from postoperative 3 weeks at the tendon-bone interface in the study group, and a normal insertion-like structure was formed at week 12, which became more mature at week 24. In the control group, however, Sharpey-like fibers could not be observed until week 12, and a normal transition through cartilage from bone to tendon was not observed at any time point. Histologic scores of the tendon-bone interface in the study group were significantly higher than those in the control group at week 6 ( P = .04), week 12 ( P < .001), and week 24 ( P = .04). As compared with the control group via micro-CT, the study group had a significantly smaller bone tunnel area at week 6 ( P = .01) and larger bone volume/total volume at week 3 ( P = .0026) and week 6 ( P = .01). Also, the study group had a significantly higher failure load at weeks 12 and 24 (both P = .03) and a significantly higher stiffness at week 24 ( P < .001) versus the control group. CONCLUSION The semitendinosus tendon graft with an intact tibial insertion in ACLR would bypass the graft avascular necrosis stage, which improves tendon-bone healing and biomechanical strength. CLINICAL RELEVANCE An alive graft in ACLR could improve tendon-bone healing and the biomechanical strength of the graft, which might be beneficial to early and intensive rehabilitation after ACLR.

Abstract
BACKGROUND The hamstring tendons are commonly harvested for anterior cruciate ligament (ACL) reconstruction with detachment of the tibial insertion. Retaining the insertion may help to preserve vascularity and viability of the graft and bypass the stages of avascular necrosis and revascularization, which might be beneficial to graft maturity. PURPOSE To investigate and compare graft maturity by magnetic resonance imaging (MRI) after ACL reconstruction with preservation or detachment of hamstring tendon tibial insertion at up to 2 years. STUDY DESIGN Randomized controlled trial; Level of evidence, 2. METHODS Forty-five patients (age range, 18-45 years) undergoing isolated ACL reconstruction with hamstring tendon were enrolled and randomized to 2 groups. The tibial insertion of the hamstring tendon was preserved in the study group (n = 21) and detached in the control group (n = 24). Patients had follow-up at 3, 6, 12, and 24 months, which consisted of the following: (1) clinical examination and (2) MRI evaluation of graft signal intensity based on signal/noise quotient (SNQ) values. Finally, 18 patients in the study group and 19 in the control group received full follow-up evaluation (ie, at all 4 time points). RESULTS All knees acquired full range of motion at 24 months without significant laxity. At each time point, the KT-1000 arthrometer revealed no significant difference between groups; the clinical scores significantly improved in both groups, although the difference between groups was not significant. In the control group, the SNQ value increased from 3 months, peaked at 6 months, and then decreased (3 months, 21.4 ± 12.7; 6 months, 25.6 ± 12; 12 months, 18.3 ± 7.7; 24 months, 15.3 ± 6.3). However, the insertion-preserved graft in the study group maintained relatively lower and unchanged signal intensity throughout all time points (3 months, 15.0 ± 11.2; 6 months, 14.9 ± 6.3; 12 months, 12.6 ± 7.0; 24 months, 14.6 ± 7.0). Between groups, there was no significant difference at 3 or 24 months ( P = .11 and .75, respectively), while the SNQ values were significantly lower in the study group versus the control group at 6 and 12 months ( P = .002 and .02, respectively). CONCLUSION The insertion-detached hamstring tendon grafts underwent a significantly increasing change in signal intensity during the first 2 years after ACL reconstruction, while the insertion-preserved grafts kept a relatively lower and unchanged signal intensity. The difference was most significant at 6 and 12 months postoperatively.

Abstract
PURPOSE Infrapatellar branch of saphenous nerve injury is a common complication following hamstring graft harvest during anterior cruciate ligament reconstruction. The direction of skin incision performed at proximal tibial metaphysis may affect the rate of iatrogenic nerve damage. Aim of the present systematic review was to evaluate evidence that would substantiate the adoption of one incision over another for hamstring graft harvesting. METHODS The available literature was systematically screened searching studies dealing with iatrogenic injury to the saphenous nerve after anterior cruciate ligament reconstruction using hamstring tendons. A search was performed using the keywords "Saphenous" and "Infrapatellar branch" in combination with "Anterior cruciate ligament", "arthroscopy" and "hamstrings", supplying no limits regard the publication year. Coleman methodological score was performed in all the retained articles. RESULTS Five articles matched the inclusion criteria. There were two randomized controlled trials, one prospective comparative study and two retrospective comparative series. Poor methodological quality was found overall. A vertical incision was found to significantly affect the presence of hypoesthesia and the extent of the area of sensory loss in three articles; no difference was registered in one, and a trend towards a lower rate of iatrogenic nerve damage using an oblique incision was found in the remaining one, without any statistical significance. CONCLUSION Although the low methodological quality of the analysed studies does not permit to draw definitive conclusions, the anatomical course of the nerve along with the results obtained in the available studies seems to suggest lower rate of neurological impairment adopting an oblique incision. This kind of incision may therefore be preferred in the routine clinical practice. LEVEL OF EVIDENCE Systematic review, Level II.

Hamstring graft tibial insertion preservation versus detachment in anterior cruciate ligament reconstruction: a prospective randomized comparative study. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY AND TRAUMATOLOGY 2016; 26:657-64. [PMID: 27388213 DOI: 10.1007/s00590-016-1812-9] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/08/2016] [Accepted: 06/18/2016] [Indexed: 11/30/2022]
Abstract
BACKGROUND Anterior cruciate ligament (ACL) reconstruction with hamstring graft (HG) is a commonly performed procedure. Despite the type of reconstruction chosen, the detached HG undergoes a remodeling process known as ligamentization. In order to shorten the ligamentization process, the maintenance of HG tibial insertion, aimed to spare the tendons vascular supply, has been postulated. The aim of this paper is to report the results of a prospective randomized study comparing clinical and MRI results between two different ACL reconstructive procedures with and without HG tibial insertion preservation. METHODS Forty patients (mean age 27.5 ± 9.5 years) were enrolled and randomly divided into two groups. The study group underwent an ACL reconstruction using a distally inserted HG, while the control group underwent a technique encompassing HG tibial detachment. Subjective and objective IKDC score was administered preoperatively and at 3-, 6-, 12- and 24-month follow-up. Graft morphology was assessed through MRI evaluation performed at 6-month follow-up. RESULTS Clinical results were excellent in both groups. Regarding MRI results, a better intra-articular graft morphology was observed in the study group (Tau = 0.313, p = 0.024). No differences in graft integration were noticed. CONCLUSION The main finding of this preliminary study is that preservation of the hamstring tibial insertion seems to enhance graft ligamentization with improved morphology of the intra-articular portion of the graft compared to a detachment of the hamstring tendons from the tibial side. Further well-designed studies with higher number of patients as well as more serial MRI evaluations are required to validate these preliminary findings.

Abstract
PURPOSE Controversies exist about the femoral tunnel preparation technique in anterior cruciate ligament (ACL) reconstruction surgeries. The aim of this study was to evaluate mid-term outcomes of transtibial (TT) technique in comparison with anteromedial portal (AMP) one. METHODS Demographic data, height, weight, period of time from injury to surgery, and follow-up duration of patients underwent ACL reconstruction using single-bundle hamstring graft by the senior author between 2007 and 2011 were evaluated, retrospectively. Mid-quadriceps circumference difference, passive range of motion of the joint, anterior drawer test, Lachman test, and pivot shift test were assessed for each case. Function of the knee joint was calculated using International Knee Documentation Committee (IKDC), Lysholm, and Tegner scores. RESULTS Of 50 cases in the AMP group (age 30.6 ± 6.5), 45 were male and of the 44 patients in the TT group (age 30.0 ± 6.5), forty were male. Mean follow-up times in the AMP and TT group were 18.2 months (range 12-84 months) and 25.7 months (range 16-48 months), respectively. No statistically significant difference was found in mid-quadriceps circumference difference (P = 0.861). Also, functional knee scores (P values of IKDC = 0.329, Lysholm score = 0.08, Tegner = 0.504) and stability tests (P values of anterior drawer test = 0.07, Lachman test = 0.486, pivot shift test = 0.348) did not differ statistically between groups. CONCLUSION There is no superiority of AMP technique on TT technique in ACL reconstructive surgeries. It could be suggested that performing a well-done technique, either TT or AMP, may be more important than only choosing a technique.
