Objectives: To compare femoral and tibial tunnel widening (TW) in patients undergoing anterior cruciate ligament (ACL) reconstruction using an interference screw (IS), or an EndoButton-Continuous Loop (EndoButton-CL®) on the femoral side, and an IS/staple on the tibial side. Methods: We retrospectively reviewed data on 46 patients who underwent arthroscopic ACL reconstruction with Achilles tendon allografting. Fixation was performed with a bioabsorbable IS (the IS group) in 24 patients (mean age 26.5 years), and with the EndoButton-CL device (the EB group) in 22 patients (mean age 28.1 years) on the femoral side. Evaluation included standardized anteroposterior (AP) and lateral radiography. The diameters of tunnels at the last follow-up visit (at a median time of 17 months postoperatively) were compared to those noted on radiographs taken 1 day postoperatively. Results: The two groups were similar in terms of age and gender distribution, the operated side, the size of the tunnel created, and the follow-up period (p>0.05). Femoral TW at the proximal and middle levels (on both anteroposterior and lateral views) in the IS group was significantly greater than in the EB group (p<0.050 for all comparisons). No significant difference in femoral TW at the distal level was evident between the groups, and tibial TW at all levels was similar in both groups (p>0.050). Conclusion: Femoral ACL graft fixation using an EndoButton-CL reduced femoral TW compared to use of an IS.

The aim of the present study was to evaluate incidence, degree and impact of tibial tunnel widening (TW) on patient-reported long-term clinical outcome, knee joint stability and prevalence of osteoarthritis (OA) after isolated anterior cruciate ligament (ACL) reconstruction. On average, 13.5 years after ACL reconstruction via patella-bone-tendon-bone autograft, 73 patients have been re-evaluated. Inclusion criteria consisted of an isolated anterior cruciate ligament rupture and reconstruction, a minimum of 10-year follow-up and no previous anterior cruciate ligament repair or associated intra-articular lesions. Clinical evaluation was performed via the International Knee Documentation Committee (IKDC) score and the Tegner and Lysholm scores. Instrumental anterior laxity testing was carried out with the KT-1000™ arthrometer. The degree of degenerative changes and the prevalence of osteoarthritis were assessed with the Kellgren-Lawrence score. Tibial tunnel enlargement was radiographically evaluated on both antero-posterior and lateral views under establishment of 4 degrees of tibial tunnel widening by measuring the actual tunnel diameters in mm on the sclerotic margins of the inserted tunnels on 3 different points (T1-T3). Afterwards, a conversion of the absolute values in mm into a 4 staged ratio, based on the comparison to the results of the initial drill-width, should provide a better quantification and statistical analysis. Evaluation was performed postoperatively as well as on 2 year follow-up and 13 years after ACL reconstruction. Minimum follow-up was 10 years. 75% of patients were graded A or B according to IKDC score. The mean Lysholm score was 90.2 ± 4.8 (25-100). Radiological assessment on long-term follow-up showed in 45% a grade I, in 24% a grade II, in 17% a grade III and in additional 12% a grade IV enlargement of the tibial tunnel. No evident progression of TW was found in comparison to the 2 year results. Radiological evaluation revealed degenerative changes in sense of a grade II OA in 54% of patients. Prevalence of a grade III or grade IV OA was found in 20%. Correlation analysis showed no significant relationship between the amount of tibial tunnel enlargement (P&gt;0.05), long-term clinical results, anterior joint laxity or prevalence of osteoarthritis. Tunnel widening remains a radiological phenomenon which is most commonly observed within the short to midterm intervals after anterior cruciate ligament reconstruction and subsequently stabilises on mid and long- term follow-up. It does not adversely affect long-term clinical outcome and stability. Furthermore, tunnel widening doesn’t constitute an increasing prevalence of osteoarthritis.

Background: It has been shown that adding lateral extra-articular tenodesis (LET) to standard anterior cruciate ligament (ACL) reconstruction significantly decreases the loads on the ACL composite graft. To date, the possible effect of LET on ACL graft incorporation is not known. Purpose: To compare the incorporation in tibial bone tunnels of a standard quadrupled semitendinosus (ST4) graft to an ST4 graft plus LET at 1 year postoperatively using magnetic resonance imaging (MRI). Study Design: Cohort study; Level of evidence, 3. Methods: A total of 62 patients who underwent ACL reconstruction were enrolled prospectively: 31 received an ST4 graft, and 31 received an ST4 graft plus LET. Graft incorporation was evaluated with MRI at the 1-year follow-up visit. The following parameters were evaluated: signal-to-noise quotient (SNQ), tibial tunnel widening, graft healing, and graft maturity according to the Howell scale. The primary endpoint was the SNQ of the ST4 graft at 1 year postoperatively; this parameter was adjusted because of unequal baseline characteristics between groups. Clinical and functional outcomes as well as incorporation of the graft were analyzed as secondary endpoints. Results: The mean adjusted SNQ was 0.5 ± 2.1 (95% CI, 0.4-4.6) in the ST4 + LET group and 5.9 ± 3.7 (95% CI, 4.7-7.0) in the ST4 group ( P = .0297). The mean tibial tunnel widening was 73.7% ± 42.2% in the ST4 + LET group versus 77.5% ± 46.7% in the ST4 group ( P = .5685). Howell grade I, indicative of better graft maturity, was statistically more frequent in the ST4 + LET group ( P = .0379). No statistically significant difference was seen between groups in terms of graft healing ( P = .1663). The Lysholm score was statistically higher in the ST4 + LET group ( P = .0058). No significant differences were found between groups in terms of the International Knee Documentation Committee subjective score ( P = .2683) or Tegner score ( P = .7428). The mean SNQ of the LET graft at the 1-year follow-up visit was 2.6 ± 4.9. Conclusion: At 1 year postoperatively, the MRI appearance of ACL grafts showed generally better incorporation and maturation when combined with LET.

AbstractThe purpose of this study was to retrospectively investigate the effects of variations in the length of the tendon within the tibial tunnel on tunnel widening (TW) following anatomical anterior cruciate ligament (ACL) reconstruction using a bone–patellar tendon–bone (BTB) graft. In total, 68 patients who underwent isolated ACL reconstructions using BTB grafts were included in this study. The patients were divided into two groups according to the length of the tendon within the tibial tunnel: group S (n = 30; tendon length, < 10 mm) and group L (n = 38; tendon length, ≥ 10 mm). Tunnel aperture area was measured using three-dimensional computed tomography (3D CT) at 1 week and 1 year postoperatively, and tibial TW (%) was calculated. The correlation coefficient between the length of the tendon within the tibial tunnel and tibial TW was also calculated. Clinical assessment was performed 1 year postoperatively, corresponding to the period of CT assessment, which involved the evaluation of the Lysholm's score, measurement of anterior knee stability using a KneeLax3 arthrometer, and the pivot-shift test. A weak positive correlation was observed between the length of the tendon within the tibial tunnel and tibial TW (r = 0.270, p = 0.026). Mean tibial tunnel aperture area increased by 19.3 ± 17.4% and 35.8 ± 25.4% in the groups S and L, respectively. TW in the group L was significantly greater than that in the group S (p = 0.004). No significant difference was observed between the two groups in any clinical outcomes. In conclusion, a longer tendinous portion within the tibial tunnel resulted in a greater tibial TW following anatomical ACL reconstructions using a BTB graft.

Osteomyelitis following arthroscopically assisted anterior cruciate ligament (ACL) reconstruction has rarely been reported in the literature. We report a case of a 20-year-old female who had delayed tibial osteomyelitis and a pretibial cyst with culture-positive, oxacillin sensitive Staphylococcus epidermidis 15 months after an ACL reconstruction with hamstring autograft. Soft tissue fixation within the tibial tunnel was with a poly-L-D-lactic acid (PLDLA) bioabsorbable interference screw. The patient underwent surgical treatment with curettage, debridement, hardware removal, and bone grafting of the tibial tunnel followed by a course of intravenous antibiotics. Arthroscopic evaluation demonstrated an intact ACL graft without any evidence of intra-articular infection. The patient returned to collegiate athletics without any complications. While the most common biologic complications include pretibial cysts, granuloma formation, tunnel widening, and inflammatory reactions, infection is exceedingly rare. Late infection and osteomyelitis are also rare but can occur and should be considered in the differential diagnosis.

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.

AbstractThe purpose of the current randomized clinical trial (RCT) was to evaluate the clinical outcomes of combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction and to compare them with those of isolated ACL reconstruction. The hypothesis was that combined ACL and ALL reconstruction will result in superior clinical outcomes in terms of the rotational stability of the knee. This prospective RCT included 57 patients (44 men and 13 women, mean age = 31 ± 7.1 years) who underwent ACL reconstruction either isolated (Group I: 25 patients) or combined with ALL reconstruction (Group II: 32 patients). The evaluation of the patients was done preoperatively and postoperatively at 6 weeks, 12 weeks, 6 months, and 12 months including a clinical examination (Lachman's test, Pivot shift's test, and Rolimeter differential anterior laxity), an objective clinical scores (objective: the International Knee Documentation Committee [IKDC] score) and a subjective clinical scores (subjective: IKDC's score, Lysholm's score, and Tegner's activity score). Postoperative complications of all the patients were recorded. There was a significant difference between the study groups at all follow-up intervals when evaluating the postoperative pivot shift test (p < 0.05) with a superior rotational stability in the group of combined ACL and ALL reconstruction. At the final follow-up evaluation, 36% of the patients from Group I and 6.2% in Group II had a grade I positive pivot shift test (p < 0.05). There was a statistically significant difference between the two groups regarding the number of patients with a grade A IKDC objective score (p < 0.05) at the 6- and 12-month follow-up intervals (p = 0.007). There was a significant difference concerning the IKDC subjective score between the two study groups in favor of the combined ACL and ALL reconstruction group at 12 months postoperatively (p = 0.048). Combined ACL and ALL reconstruction technique was demonstrated to be effective in obtaining a superior control of the rotational knee instability and to improve the clinical objective and subjective outcomes when compared with isolated ACL reconstruction in sports patients with high-grade pivoting shifts.

Abstract Background: Anterior Cruciate Ligament (ACL) reconstruction is a standard technique for treatment of patients with an ACL tear. According to clinical observations, lateral knee pain is highly associated with a teared ACL, this correlation so far has remained unnoticed in the literature. In this study, we aim to investigate the relationship of lateral knee pain with diagnosis of torn ACL.Methods: This pilot study was conducted on 30 candidates of ACL reconstruction. The participants underwent surgical reconstruction of ACL; Then Visual Analogue Scale (VAS) was used to measure pain at three time points of preoperative, first and second postoperative visits. Results: A total of 26 participants (86.7%) were male with a mean age of 27.3±5.06 years. The results demonstrated that the intensity of lateral knee pain felt by the subjects significantly diminished during subsequent postoperative referrals (P-value<0.001). However, other variables including sex, age, and type of surgery (bone-patella tendon-bone and hamstring tendon) caused no significant difference in terms of pain reduction (p>0.05). Conclusions: Lateral knee pain is likely related with anterior cruciate ligament tear and favors its diagnosis. Also, the evaluation of lateral knee pain may contribute in Anterior Cruciate Ligament reconstruction (ACLR) monitoring in the follow-up stage.

<p class="abstract">We present a 23-year-old male with an early anterior cruciate ligament (ACL) reconstruction failure due to lateral wall blow-out, diagnosed on day one post-op. We were able to perform the revision using the original graft, and maintaining the initial tibial fixation, revising only the femoral fixation. At 1-year follow-up the patient is asymptomatic. In the early ACL reconstruction failures due to femoral wall blowout, it is possible to perform the revision surgery using the same graft and maintaining the same tibial fixation. This avoids de morbidity of a new graft harvest and the need for a new tibial tunnel.</p>

Abstract Purpose To evaluate clinical ad radiological outcomes of anterior cruciate ligament (ACL) reconstruction with an immunochemically modified porcine patellar tendon xenograft controlled against human Achilles tendon allograft at 24-month minimum follow-up. Methods 66 patients undergoing arthroscopic ACL reconstruction were randomized into 2 groups: 34 allografts and 32 xenografts treated to attenuate the host immune response. Follow-up was 24-month minimum. Anterior knee stability was measured as KT − 1000 side-to-side laxity difference (respect to the contralateral healthy knee). Functional performance was assessed by one-legged hop test. Objective manual pivot-shift test and subjective (IKDC, Tegner and SF-36) outcomes were collected. MRI and standard X-Ray were performed. Results 61 subjects (32 allograft, 29 xenograft) were evaluated at 12 and 24 months. Six of the subjects in xenograft group (20.6%) got an infection attributed to a water-based pathogen graft contamination in processing. Intention-to-treat analysis (using the last observation carried forward imputation method) revealed higher KT − 1000 laxity in xenograft group at 24-month follow-up (P = .042). Also pivot-shift was higher in xenograft group at 12-month (P = .015) and 24-month follow-up (P = .038). Per-protocol analysis (missing/contaminated subjects excluded) did not revealed clinical differences between groups. Tibial tunnel widening in the allograft group was low, whereas xenograft tunnel widening was within the expected range of 20–35% as reported in the literature. No immunological reactivity was associated to xenograft group. Conclusions High infection rate (20.6%) was reported in xenograft group. Both groups of patients achieved comparable clinical outcomes if missing/contaminated subjects are excluded. Improved harvesting/processing treatments in future studies using xenografts for ACL reconstruction are needed to reduce infection rate, otherwise xenograft should not be used in ACL reconstruction. Level of evidence Multicenter and double-blinded Randomized Controlled Clinical Trial, Level I.

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.
