Abihssira S, Benistan K, Nourissat G. Functional benefit of joint surgery in patients with non-vascular Ehlers-Danlos syndrome: results of a retrospective study. Orphanet J Rare Dis 2024; 19:351. [PMID: 39313806 PMCID: PMC11421124 DOI: 10.1186/s13023-024-03261-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2024] [Accepted: 06/16/2024] [Indexed: 09/25/2024] Open
Abstract
BACKGROUND Ehlers-Danlos syndrome (EDS) is a hereditary disease characterised by joint hypermobility, skin hyperextensibility and tissue fragility. Hypermobile EDS (hEDS is the more frequent subtype. Joint surgery may benefit certain patients after failure of medical treatments, but there is no consensus on the optimal surgical management of patients with hEDS. The aims of this retrospective study were to chart the surgical management of patients with hEDS, to determine the role of arthroscopy and to evaluate the functional results of joint surgery, including the reintervention rates. RESULTS A total of 69 patients with non-vascular EDS were evaluated (60 female; 87%). Mean (SD) age at first surgery was 25.6 ± 11.1 years. Among the 69 patients, first surgeries were carried out on the knee (n = 50; 39.4%), ankle (n = 28; 22.0%), shoulder (n = 22; 17.3%), wrist (n = 18; 14.2%) and elbow (n = 9; 7.1%). One-fifth of all first operations (20.8%) were carried out by arthroscopy, most often on the knee (36% of knee surgery cases). At the time of primary surgery, the surgeon was alerted to the diagnosis or suspicion of hEDS in only 33.9% of patients. The rate of reoperations (2 to ≥ 5) was 35.7% (10/28) for the ankle, 40.9% (9/22) for the shoulder, 44.4% (4/9) for the elbow, 50% (9/18) for the wrist and 60% (30/50) for the knee. Local or regional anaesthesia was badly tolerated or ineffective in 27.8%, 36.4% and 66.6% of operations on the wrist, shoulder and elbow, respectively. Overall, the majority of patients (> 70%) were satisfied or very satisfied with their surgery, particularly on the non-dominant side. The lowest satisfaction rate was for shoulder surgery on the dominant side (58.3% dissatisfied). CONCLUSIONS Surgery for joint instability has a greater chance of success when it is carried out in patients with a known diagnosis of EDS before surgery. The majority of patients were satisfied with their surgery and, with the exception of the knee, there was a low rate of reoperations (≤ 50%). Arthroscopic procedures have an important role to play in these patients, particularly when surgery is performed on the knee.

Quadriceps Tendon With Bone Autograft Has Better Stability and Magnetic Resonance Imaging Maturation Than Hamstring Tendon Autograft After Anterior Cruciate Ligament Reconstruction in Patients With Knee Hyperextension. Arthroscopy 2024; 40:1234-1244. [PMID: 37597704 DOI: 10.1016/j.arthro.2023.08.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2023] [Revised: 07/22/2023] [Accepted: 08/10/2023] [Indexed: 08/21/2023]
Abstract
PURPOSE To compare the clinical outcomes of anterior cruciate ligament (ACL) reconstruction between methods using quadriceps tendon with bone (QTB) and hamstring tendon (HT) in patients with hyperextension of the knee. METHODS The medical records of patients with knee hyperextension greater than 8° who underwent arthroscopic ACL reconstruction between October 2010 and October 2020 with follow-up for at least 2 years (median, 3 years; interquartile range [IQR], 2.0-4.6 years) were retrospectively reviewed. Side-to-side difference in anterior translation, pivot-shift test grade, Lysholm score, and graft intensity using the Howell grade on magnetic resonance imaging at final follow-up were compared between the QTB and HT groups. RESULTS The HT and QTB groups consisted of 42 patients and 21 patients, respectively. The overall mean age was 21.5 years (range, 14-48 years), and the median Tegner Activity Scale score was 6 (range, 3-9). Postoperatively, the median side-to-side difference in anterior translation was 1.75 mm (IQR, 1-3 mm) in the HT group and 1.0 mm (IQR, 0-1.75 mm) in the QTB group (P = .01). Pivot-shift testing showed grade 0 in 74.7%, grade 1 in 18.7%, and grade 2 in 6.6% of patients in the HT group and grade 0 in 85.7% and grade 1 in 14.3% of those in the QTB group (P = .03). The median postoperative Lysholm score was 99 in both groups. Graft signal intensity showed a significant between-group difference: grade I in 52%, grade II in 36%, and grade III in 12% of patients in the HT group versus grade I in 85.7%, grade II in 9.5%, and grade III in 4.8% of those in the QTB group (P = .03). CONCLUSIONS In patients who underwent ACL reconstruction for hyperextension of the knee, QTB yielded better clinical outcomes than HT with respect to anterior stability, rotational stability, and graft signal intensity on median 2-year follow-up magnetic resonance imaging. LEVEL OF EVIDENCE Level III, retrospective case-control study.

Lower rates of return to sport in patients with generalised joint hypermobility two years after ACL reconstruction: a prospective cohort study. BMC Sports Sci Med Rehabil 2023; 15:100. [PMID: 37573382 PMCID: PMC10422717 DOI: 10.1186/s13102-023-00707-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 07/24/2023] [Indexed: 08/14/2023]
Abstract
BACKGROUND Generalised joint hypermobility (GJH) has been associated with an increased risk of suffering an anterior cruciate ligament (ACL) injury. Patients with GJH exhibit lower muscle strength and poorer scores for patient-reported outcomes after ACL reconstruction, compared with patients without GJH. The aim of this study was to examine differences in the percentages of patients who return to sport (RTS) or pre-injury level of activity (RTP), muscle function and patient-reported outcomes at the time of RTS or RTP, as well as the time of RTS or RTP in patients with GJH compared with patients without GJH in the first two years after ACL reconstruction. METHODS This prospective study used data from an ACL- and rehabilitation-specific register located in Gothenburg, Sweden. Patients aged between 16 and 50, who had a primary ACL injury treated with reconstruction, were included. Data up to two years after ACL reconstruction were used and consisted of achieving RTS and RTP, results from isokinetic muscle function tests for knee extension and flexion and patient-reported outcomes (Knee Self-Efficacy Scale, Knee injury and Osteoarthritis Outcome Score and ACL-Return to Sport after Injury scale) at the time of RTS, as well as the time of RTP. A Beighton Score of ≥ 5/9 was used to define GJH. A Tegner Activity Scale of ≥ 6 was used to define RTS, while a Tegner equal to or above pre-injury level was used to define RTP. RESULTS A total of 1,198 patients (54.7% women) with a mean age of 28.5 ± 8.6 years were included. A smaller proportion of patients with GJH achieved RTS compared with patients without GJH (49.2% vs. 57.3%, Odds ratio: 0.720, p = 0.041). Furthermore, patients with GJH were marginally less symmetrical on the knee extension strength test, expressed as a Limb Symmetry Index, at the time of RTP compared with patients without GJH (87.3 ± 13.5 vs. 91.7 ± 14.3, Cohen's d = 0.142, p = 0.022). No further differences were found between groups regarding any muscle function tests or patient-reported outcomes. CONCLUSION A smaller proportion of patients with GJH achieved RTS compared with patients without GJH. Patients with GJH displayed less symmetrical knee extension strength at the time of RTP compared with patients without GJH.

Abstract
OBJECTIVES To determine the 12-month risk of a second anterior cruciate ligament (ACL) injury in a population of patients with and without generalised joint hypermobility (GJH) who return to sports (RTS) at competition level after ACL reconstruction (ACL-R). METHODS Data were extracted from a rehabilitation-specific registry for 16-50-year-old patients treated with ACL-R between 2014 and 2019. Demographics, outcome data and the incidence of a second ACL injury within 12 months of RTS, defined as a new ipsilateral or contralateral ACL, were compared between patients with and without GJH. Univariable logistic regression and Cox proportional hazards regression were performed to determine the influence of GJH and time of RTS on the odds of a second ACL injury, and ACL-R survival without a second ACL injury after RTS. RESULTS A total of 153 patients, 50 (22.2%) with GJH and 175 (77.8%) without GJH, were included. Within 12 months of RTS, 7 (14.0%) patients with GJH and 5 (2.9%) without GJH had a second ACL injury (p=0.012). The odds of sustaining a second ipsilateral or contralateral ACL injury were 5.53 (95% CI 1.67 to 18.29) higher in patients with GJH compared with patients without GJH (p=0.014). The lifetime HR of a second ACL injury after RTS was 4.24 (95% CI 2.05 to 8.80; p=0.0001) in patients with GJH. No between-group differences were observed in patient-reported outcome measures. CONCLUSION Patients with GJH undergoing ACL-R have over five times greater odds of sustaining a second ACL injury after RTS. The importance of joint laxity assessment should be emphasised in patients who aim to return to high-intensity sports following ACL-R.

Influence of Graft Type on Lower Extremity Functional Test Performance and Failure Rate After Anterior Cruciate Ligament Reconstruction. Sports Health 2023; 15:606-614.

Abstract
BACKGROUND Both autografts and allografts are used to reconstruct the anterior cruciate ligament (ACL) after injury; however, it is unclear whether graft source affects lower extremity functional test performance or failure rate in an active military population. OBJECTIVE To compare lower extremity functional test performance and graft failure rates between ACL grafts [allograft, hamstring, bone-patellar tendon-bone (BTB)]. STUDY DESIGN Cross-sectional. LEVEL OF EVIDENCE Level 2. METHODS Ninety-eight cadets entering a US Service Academy with a history of unilateral ACL reconstruction (ACLR) agreed to participate. Before basic training, participants completed 4 lower extremity functional tests. Active injury surveillance was conducted within the study cohort to identify all subsequent graft failures. RESULTS Cadets with hamstring autografts outperformed the BTB and allograft groups on the Lower Quarter Y-Balance Test-Posteromedial direction and single-leg hop test, respectively. No differences were detected by graft type for the other functional tests. The incidence of subsequent ipsilateral graft failures in patients with autograft was 8.11%. No failures were observed in the allograft group during the follow-up period. After controlling for sex, joint hypermobility, and time since injury and surgery, the risk of graft failure was 9.8 times higher for patients with a hamstring autograft than with a BTB (P = 0.045). CONCLUSION After ACLR, graft type appears to influence some single-limb measures of lower extremity function and the risk of subsequent failure. Hamstring autografts demonstrated better functional performance but increased risk of graft failure. CLINICAL RELEVANCE Surgeons need to weigh the pros and cons of all graft options in relation to the patient's lifestyle. Regardless of graft type, individuals with an ACLR may require additional rehabilitation to regain neuromuscular control during dynamic single-limb tasks and mitigate graft failure.

Abstract
PURPOSE The outcomes of anterior cruciate ligament reconstruction (ACLR) in patients with generalized joint laxity (GJL) are not clearly understood. In this study, we compared the outcomes of ACLR with quadruple hamstring autograft between GJL and non-GJL patients. METHODS In a retrospective case-control study, 36 patients with GJL, according to the Beighton and Horan Joint Mobility Index, who underwent ACLR surgery, were included. Forty-four group-matched non-GJL patients were included in the control group. The mean follow-up of the patients was 20.65 ± 6.93 months. The outcomes of ACLR were evaluated by the Lachman test, pivot shift test, anterior tibial translation and KT-1000 side-to-side difference, and International Knee Documentation Committee (IKDC) scale. RESULTS The results of the Lachman and pivot shift test were not significantly different between the GJL and non-GJL patients (P = 0.67 and P = 0.27, respectively). The mean anterior tibial translation was 7.06 ± 1.41 mm in the GJL group and 6.11 ± 1.53 mm in the non-GJL group (P = 0.006). The mean KT-1000 side-to-side difference was 2.25 ± 1.31 mm in the case and 2.5 ± 1.44 mm in the control group (P = 0.42). The mean IKDC score of the patients was not significantly different between the GJL and non-GJL groups (66.1 ± 20.6 vs. 69.9 ± 16.1, P = 0.35). ACLR failure occurred in 2 (5.5%) patients of the GJL group and no patients of the control group (P = 0.21). CONCLUSION The present findings suggest ACLR with quadruple hamstring autograft as an adequate treatment for GJL patients, at least in short-term follow-up.

Abstract
BACKGROUND Excessive general joint laxity, a negative prognostic factor in joint instability, has not been studied to determine its relationship with bipolar bone loss in anterior shoulder instability. PURPOSE/HYPOTHESIS This study aimed to investigate the characteristics of bipolar bone defects in the presence of excessive joint laxity and the clinical outcomes based on the on-track/off-track theory. We hypothesized that (1) patients with excessive joint laxity might have less significant bipolar bone defects compared with those without excessive joint laxity and (2) no significant difference would be found in the clinical outcomes, including recurrence rate. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS This study included 81 patients who had undergone arthroscopic Bankart repair, with (group L; n = 33) or without (group N; n = 48) excessive joint laxity. The presence of excessive joint laxity was defined as a score of ≥4 using Beighton and Horan criteria preoperatively. Bipolar bone lesions were assessed using preoperative 3-dimensional computed tomography. Additional remplissage was performed for cases with off-track or positive engagement test in borderline on-track lesions. The functional outcomes at the 2-year follow-up were assessed using the recurrence rate, Subjective Shoulder Value, Rowe score, University of California Los Angeles shoulder score, active range of motion, and the sports/recreation activity level. RESULTS No significant difference was found in the glenoid bone defect between groups (14.1%, group L; 14.4%, group N). Off-track lesions were identified in 39.4% (13/33) of group L and 14.6% (7/48) of group N (P = .011). The mean Hill-Sachs interval to glenoid track ratio was 83.1% in group L and 75.2% in group N (P = .021). Additional remplissage procedures were more frequently performed in group L (48.5%; 16/33) than in group N (16.7%; 8/48) (P = .002). However, no significant difference was observed in the shoulder functional scores and recurrence rates between the groups. CONCLUSION Patients with anterior shoulder instability and excessive joint laxity had significantly wider Hill-Sachs lesions and more off-track lesions than did those with normal joint laxity despite the lack of a significant difference in the glenoid bone defect. However, these differences in the Hill-Sachs lesion were not related to differences in the functional outcomes between the groups.

Abstract
Generalized joint hypermobility (GJH), or laxity, is defined as hyperextensibility of the synovial joints. Hypermobility is caused by alterations in the connective tissues, in turn caused by various factors including impaired function of collagen proteins. For measurement of knee GJH, we highly recommend using the Beighton score, the most frequently used method in both the sports medicine and other literature. Our recommendations on how to treat patients with anterior cruciate ligament (ACL) injury with generalized joint hypermobility include the following: (1) use patellar-tendon or quadriceps tendon autograft for ACL reconstruction; (2) always consider performing a lateral extra-articular tenodesis; and (3) make sure patients pass a return to sport test battery including strength, hop performance, subjective knee function, and movement quality. Delay to return to sport may be as long as 1 year after surgery.

Abstract
Objectives To investigate the association between generalised joint hypermobility (GJH) and ACL injury risk. Secondary aims involved evaluating associations between GJH and postoperative outcome (including graft-failure risk, knee laxity and patient-reported outcome). Furthermore, we aimed to compare the performance of different grafts in patients with GJH. Methods Databases MEDLINE/PubMed, EMBASE and the Cochrane Library were searched, including 2760 studies. Two reviewers independently screened studies for eligibility. A modified version of the MINORS score was applied for quality appraisal. Studies assessing GJH while reporting the risk of ACL injury and/or postoperative outcome were included. Results Twenty studies were included, using several different methods to determine GJH. There was consistent evidence showing that GJH is a risk factor for unilateral ACL injury in males, while in females, the results were conflicting. There was limited evidence associating GJH with increased knee laxity 5 years postoperatively. There was consistent evidence of inferior postoperative patient-reported outcome in patients with GJH. Moreover, there was limited yet consistent evidence indicating that patellar-tendon autografts are superior to hamstring-tendon autografts in patients with GJH in terms of knee laxity and patient-reported outcome. There was insufficient evidence to draw conclusions regarding the outcomes of bilateral ACL injury and graft failure. Conclusions In men, GJH was associated with an increased risk of unilateral ACL injury. Moreover, GJH was associated with greater postoperative knee laxity and inferior patient-reported outcome. Based on the available evidence, a patellar-tendon autograft appears to be superior to a hamstring-tendon autograft in patients with GJH. However, the included studies were heterogeneous and there is a need for consensus in the assessment of GJH within sports medicine.

Bone-patellar tendon-bone autograft could be recommended as a superior graft to hamstring autograft for ACL reconstruction in patients with generalized joint laxity: 2- and 5-year follow-up study. Knee Surg Sports Traumatol Arthrosc 2018; 26:2568-2579. [PMID: 29502168 DOI: 10.1007/s00167-018-4881-y] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/01/2017] [Accepted: 02/28/2018] [Indexed: 01/11/2023]
Abstract
PURPOSE The present study aimed to compare 2- and 5-year outcomes of ACL reconstruction between patients with and without generalized joint laxity and to perform comparative evaluation between two types of grafts used for ACL reconstruction in patients with generalized joint laxity. METHODS Two hundred and thirty-seven patients who underwent ACL reconstruction from 2001 to 2008 were included. Patients were classified into two groups according to the presence or the absence of generalized joint laxity, and further subdivided into two subgroups based on the type of graft used: bone-patellar tendon-bone (BPTB) or hamstring. Generalized joint laxity was assessed with the Beighton and Horan criteria using a point scoring system. Stability reflected by the Lachman test, pivot-shift test, and anterior translation measured with KT-2000, and functional outcomes reflected by Lysholm knee score, and International Knee Documentation Committee (IKDC) subjective score were investigated. IKDC objective grade and radiographic grade were also assessed. Clinical assessments were conducted preoperatively and at 2 and 5 years after operation. RESULTS Two-year follow-up results showed that patients with generalized joint laxity receiving hamstring grafts had poorer outcomes than those without generalized joint laxity. Five-year follow-up results showed that patients with generalized joint laxity experienced poorer outcomes than patients without generalized joint laxity, irrespective of the type of graft. Comparison of grafts used showed that, in patients with generalized joint laxity, BPTB graft provided significantly better stability and functional outcomes than hamstring graft at both 2- and 5-year follow-ups. Comparisons between serial outcomes measured at 2 and 5 years demonstrated that stability and functional outcomes deteriorated over time in patients with generalized joint laxity. CONCLUSIONS Less satisfactory stability and functional outcomes were noted in patients with generalized joint laxity, compared to patients without generalized joint laxity. Comparisons of stability and functional outcomes after ACL reconstruction in patients with generalized joint laxity between two different grafts demonstrated that BPTB graft achieves better results than hamstring graft.

Y-reconstruction could be better for ACL reconstruction in knee hyperextension versus double-bundle double-tunnel technique: a retrospective comparative study of 56 patients. Arch Orthop Trauma Surg 2018; 138:827-834.

Abstract
PURPOSE To compare the clinical outcomes of double-bundle (DB) single-tibial tunnel technique and double-tunnel technique for ACL reconstruction in patients with knee hyperextension. METHODS Defined as having constitutional hyperextension of greater than 10°, 56 patients with knee hyperextension who underwent ACL reconstruction were included in this study. To exclude concomitant lesions, preoperative magnetic resonance imaging (MRI) was performed in all knees. 24 patients (Group A) were treated with the anatomic DB/single-tibial tunnel ACL reconstruction and 32 patients (Group B) were treated with DB/double-tibial tunnel ACL reconstruction, all the included patients had knee hyperextension. Clinical results were evaluated by the extension angle, ROM, IKDC 2000 subjective score, rotational stability, pivot-shift test and anterior-posterior translation test before the operation and at the end of follow-up. MRI scan of the knee positioned in full extension was performed after 6 months post-operation. Location of tibial tunnels and graft signal intensity were assessed according to the MRI. RESULTS Postoperative extension deficit was detected in Group B, ROM of the injured knee in Group A was from extension angle 8.91 ± 3.16° to flexion angle 115.58 ± 10.53°. ROM of the injured knee in Group B was from extension angle - 2.13 ± 5.88° to flexion angle 119.25 ± 12.63°. Flexion angles of two groups did not show any significant difference (p = 0.24), while extension angles were quite different (p < 0.0001). Group A was slightly higher than Group B in IKDC subjective scores, but without significant difference (Group A 45.1 ± 6.5, Group B 42.4 ± 4.8, p = 0.09). There was no significant difference between two groups in pivot-shift test. Post-operational MRI showed more anterior located tibial tunnel and higher graft signal intensity in Group B when compared with Group A. One patient in the Group B had ligament retear, and required revision surgery. CONCLUSION DB/single-tibial tunnel technique restored the knee stability and overcame the shortcomings (such as knee extension deficit and graft impingement) of DB/double tibial tunnel, which might be more suitable for ACL reconstruction in knees with hyperextension.

Abstract
BACKGROUND The purposes of this investigation were to compare outcomes of anterior cruciate ligament (ACL) reconstruction between patients with generalized joint laxity and those without it and to investigate the effect of generalized joint laxity on outcomes of ACL reconstruction from 2 to 8 years postoperatively. METHODS We retrospectively reviewed 163 patients who had undergone unilateral ACL reconstruction from January 2001 to December 2008. Patients were divided into 2 groups according to presence or absence of generalized joint laxity. The proportions of patients with meniscectomy, graft rupture, and contralateral ACL rupture were compared. Rupture rates were compared with Kaplan-Meier analysis. The Lachman test, pivot-shift test, and anterior translation measured with the KT-2000 arthrometer were evaluated. The Lysholm knee score and International Knee Documentation Committee (IKDC) subjective score were compared. The IKDC objective grade and radiographic grade were also evaluated. Follow-up assessments were performed at 2, 5, and 8 years postoperatively. RESULTS The proportions of meniscectomy, graft rupture, and contralateral ACL rupture in patients with generalized joint laxity were higher than in patients without generalized joint laxity during the whole evaluation period. However, differences in proportions and cumulative rupture rates did not reach significance (p > 0.05). Patients with generalized joint laxity had less stability and poorer functional outcomes at the 8-year follow-up compared with patients without generalized joint laxity. With regard to the Lachman test and anterior translation, poorer results were shown in patients with generalized joint laxity than in patients without generalized joint laxity during the whole evaluation period. The results of pivot-shift testing differed significantly at 5 years (p = 0.002) and 8 years (p = 0.007). Patients with generalized joint laxity also had worse Lysholm knee scores and IKDC subjective scores during the whole evaluation period; these differences may not be clinically important. Comparisons between serial outcomes measured at 2, 5, and 8-year follow-ups within each patient group showed that anterior translation (p = 0.002), Lysholm knee score (p = 0.014), and IKDC subjective score (p = 0.002) deteriorated over time, although the values at 8 years were similar to those at 5 years, in patients with generalized joint laxity. CONCLUSIONS Generalized joint laxity as an inherent physiologic characteristic of patients was related to a significant adverse effect on stability and functional outcomes of ACL reconstruction for patients followed for 2 to 8 years. Generalized joint laxity should be considered a risk factor for poor outcomes after ACL reconstruction. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
PURPOSE To evaluate the effect of knee hyperextension on dynamic in vivo kinematics after anterior cruciate ligament reconstruction (ACL-R). METHODS Forty-two patients underwent unilateral ACL-R. Twenty-four months after surgery, subjects performed level walking and downhill running on a treadmill while dynamic stereo radiographs were acquired at 100 (walking) and 150 Hz (running). Tibiofemoral motion was determined using a validated model-based tracking process, and tibiofemoral translations/rotations were calculated. The range of tibiofemoral motions from 0 to 10% of the gait cycle (heel strike to early stance phase) and side-to-side difference (SSD) were calculated. Maximum knee extension angle of ACL-reconstructed knees during walking was defined as active knee extension angle in each subject. Correlations between maximum knee extension angle and tibiofemoral kinematics data were evaluated using Spearman's rho (P < 0.05). RESULTS No significant correlation was observed between maximum knee extension angle and the range of anterior tibial translation during functional activities in the ACL-R knees. Maximum knee extension angle was weakly correlated with internal tibial rotation range in ACL-R knee during running (ρ = 0.376, P = 0.014); however, maximum extension angle was not correlated with SSD of internal tibial rotation. SSD of internal tibial rotation was -0.4° ± 1.9° (walking), -1.6° ± 3.1° (running), indicating ACL-R restored rotatory knee range of motion during functional movements. CONCLUSION Knee hyperextension was not significantly correlated with greater SSD of anterior translation and internal rotation. The clinical relevance is that knee hyperextension does not adversely affect kinematic outcomes after ACL-R and that physiologic knee hyperextension can be restored after ACL-R when knee hyperextension is present.

Abstract
PURPOSE The aim of this study was to investigate whether the severity of generalized joint laxity influences preoperative and postoperative clinical outcomes and if patients with severe generalized joint laxity would require a thicker polyethylene (PE) liner during total knee arthroplasty (TKA). METHODS A total of 338 female patients undergoing TKA were divided into two groups according to generalized joint laxity. Preoperative and postoperative (at 3 years) patellofemoral scale, AKS, WOMAC, ROM, and satisfaction VAS were compared between the two groups. Additionally, PE liner thickness was compared. RESULTS Preoperatively, flexion contracture and WOMAC stiffness scores in the severe laxity group were significantly lower than those in the no to moderate laxity group (p < 0.001 for both). There was no significant difference in postoperative clinical outcomes of patellofemoral scale, AKS, WOMAC, or ROM or in satisfaction VAS between the two groups. There was a significant difference in PE liner thickness between the two groups (10.3 ± 1.3 versus 11.4 ± 1.2, p = 0.043). CONCLUSIONS There was no significant difference of clinical outcomes between the patients with and without severe generalized joint laxity after 3 years of follow-up after TKA, even though preoperative clinical outcomes indicated that the patients with severe generalized joint laxity showed significantly smaller flexion contraction and better WOMAC stiffness score. Since patients with generalized joint laxity require a thicker PE liner, care should be taken to avoid cutting too much bone from patients with severe generalized joint laxity.

Abstract
BACKGROUND The aim of the present study was to investigate the relationship between generalised ligamentous laxity (GLL) and requirement for revision anterior cruciate ligament (ACL) reconstruction. METHODS The study cohort consisted of 139 patients undergoing primary ACL reconstruction, 44 patients undergoing revision ACL surgery and a control group of 70 patients without any knee ligament injury. A Beighton score of four or more was classified as generalised ligamentous laxity. RESULTS The primary and revision ACL surgery groups had an increased incidence of GLL compared to the control group (p<0.05). The revision ACL surgery group also had higher incidence of GLL as compared to primary ACL surgery group (p<0.05). There was a sub group within the revision cohort, who had failure of the original surgery without an identifiable cause (biological failure). The incidence of GLL in this group was significantly higher than the primary surgery group (p<0.05). CONCLUSIONS The findings of this study suggest that GLL may be associated with a higher risk of ACL injury and an increased risk of graft failure after primary ACL reconstruction. Based on the results of our study we feel that in the presence of GLL an autogenous graft may not be the best option for either primary or revision ACL reconstruction. LEVEL OF EVIDENCE 3 (III).

Abstract
BACKGROUND The modified Broström procedure for chronic lateral ankle instability (CLAI) has presented outstanding clinical results. However, after the procedure, some patients with generalized ligamentous laxity have experienced a recurrence of ankle instability. PURPOSE To understand the effect of generalized ligamentous laxity on prognosis and risk of recurrence in a cohort of patients with CLAI after the modified Broström procedure. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A total of 199 ankles from 188 patients underwent the modified Broström procedure for CLAI with a mean follow-up of 60.1 months (range, 48-108 months). Generalized ligamentous laxity was assessed in all patients. The Karlsson-Peterson ankle score (Karlsson score), talar tilt angle, and anterior displacement of the talus were used to evaluate clinical and radiological outcomes. Risk factors associated with clinical outcomes were evaluated using bivariate analysis and logistic regression analysis. Survival outcomes were compared using Kaplan-Meier analysis. RESULTS Generalized ligamentous laxity was evident in 42 cases (21.1%). The average Karlsson score improved from 54.6 ± 7.1 preoperatively to 87.9 ± 7.2 at last follow-up (P < .001). The presence of generalized ligamentous laxity was significantly associated with poor clinical and radiological outcomes. The rates of clinical failure were 10.8% and 45.2% in the nonlaxity group and the laxity group, respectively (P < .001). According to bivariate analysis, generalized ligamentous laxity, syndesmosis widening, osteochondral lesion of the talus, high preoperative talar tilt angle (>15°), and high preoperative anterior displacement of the talus (>10 mm) were significantly associated with clinical failure. Multivariate logistic regression analysis revealed that generalized ligamentous laxity was the most important independent predictor of clinical failure after the modified Broström procedure. The cumulative success rates for the nonlaxity group were significantly superior to those for the laxity group in Kaplan-Meier curves (P < .001). CONCLUSION Generalized ligamentous laxity is an independent predictor of poor outcomes and a risk factor of recurrent instability following the modified Broström procedure for CLAI.

Abstract
PURPOSE The aim of this study was to compare postoperative outcomes after anatomic double-bundle anterior cruciate ligament reconstruction (ACLR) in extreme knee hyperextension versus normal to mild knee hyperextension. METHODS For 100 patients who underwent anatomic double-bundle ACLR using semitendinosus tendon, we evaluated the side-to-side difference (SSD) in anterior tibial translation (measured on stress radiographs) and rotational stability (assessed by the pivot-shift test) 2 years after surgery. Loss of extension (LOE) was evaluated on lateral radiographs of both knees in full extension, and graft integrity was assessed during second-look arthroscopy 1 to 2 years after surgery. In accordance with the Beighton and Honan criteria, patients with an extension angle less than or equal to 10° in the contralateral uninjured knee composed the group with 10° or less hyperextension (N group), and those with an extension angle of greater than 10° composed the group with more than 10° hyperextension (H group). Postoperative results were compared between these groups. RESULTS Mean extension angles in the N and H groups were 5.8° ± 2.9° and 14.7° ± 3.0°, respectively. The mean SSD in anterior translation was 2.2 ± 2.9 mm for the N group and 2.8 ± 2.9 mm for the H group, with no significant difference. The positive ratios on the pivot-shift test were not significantly different between the groups. Mean LOE in the N and H groups was -0.7° ± 3.7° and 1.3° ± 3.3°, respectively, with a significant difference (P = .007). During second-look arthroscopy, 6 of 58 knees in the N group and 13 of 42 knees in the H group had superficial graft laceration of the anteromedial bundle graft, with a significant difference (P = .01) seen between groups. CONCLUSIONS Anatomic double-bundle ACLR for extreme knee hyperextension may attain the same postoperative anterior and rotational stability as seen in knees with normal to mild hyperextension. However, it increased superficial graft laceration. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
This report details the reconstruction of the anterior cruciate ligament in an 18-year-old man with Ehlers-Danlos syndrome (EDS). The reduced mechanical properties of the tissue in EDS can pose a challenge to the orthopaedic surgeon. In this case, we describe the use of a hamstring autograft combined with a Ligament Advanced Reinforcement System (LARS). There was a good radiographical, clinical, and functional outcome after two years. This technique gave a successful outcome in the reconstruction of the ACL in a patient with EDS and therefore may help surgeons faced with the same clinical scenario.

Abstract
Purpose. The purpose of this study was to determine whether intraoperative prereconstruction stability measurements and/or patient characteristics were associated with final knee stability after computer-assisted ACL reconstruction. Methods. This was a retrospective review of all patients who underwent computer-assisted single-bundle ACL reconstruction by a single surgeon. Prereconstruction intraoperative stability measurements were correlated with patient characteristics and postreconstruction stability measurements. 143 patients were included (87 male and 56 female). Average age was 29.8 years (SD ± 11.8). Results. Females were found to have significantly more pre- and postreconstruction internal rotation than males (P < 0.001 and P = 0.001, resp.). Patients with additional intra-articular injuries demonstrated more prereconstruction anterior instability than patients with isolated ACL tears (P < 0.001). After reconstruction, these patients also had higher residual anterior translation (P = 0.01). Among all patients with ACL reconstructions, the percent of correction of anterior translation was found to be significantly higher than the percent of correction for internal or external rotation (P < 0.001). Conclusion. Anterior translation was corrected the most using a single-bundle ACL reconstruction. Females had higher pre- and postoperative internal rotation. Patients with additional injuries had greater original anterior translation and less operative correction of anterior translation compared to patients with isolated ACL tears.

Abstract
Anterior cruciate ligament (ACL) surgery is being increasingly performed in the adolescent population. Computer navigation offers a reliable way to quantitatively measure knee stability during ACL reconstruction. A retrospective review of all adolescent patients (<18 years old) who underwent computer-assisted primary single bundle ACL reconstruction by a single surgeon from 2007 to 2012 was performed. The average age was 15.8 years (SD 3.3). Female adolescents were found to have higher internal rotation than male adolescents both pre- (25.6° vs 21.7°, P=0.026) and post-reconstruction (20.1° vs 15.1°, P=0.005). Compared to adults, adolescents demonstrated significantly higher internal rotation both pre- (23.3° vs 21.5°, P=0.047) and post-reconstruction (17.1° vs 14.4°, P=0.003). They also had higher total rotation both pre- (40.9° vs 38.4°, P=0.02) and post-reconstruction when compared to adults (31.56° vs 28.67°, P=0.005). In adolescent patients, anterior translation was corrected more than rotation. Females had higher pre- and residual post-reconstruction internal rotation compared to males. When compared to adults, adolescents had increased internal rotation and total rotation both pre-and post-reconstruction.

Kim SJ, Kim SH, Park BK, Chun YM. Arthroscopic stabilization for recurrent shoulder instability with moderate glenoid bone defect in patients with moderate to low functional demand. Arthroscopy 2014; 30:921-7. [PMID: 24857422 DOI: 10.1016/j.arthro.2014.03.023] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2013] [Revised: 03/18/2014] [Accepted: 03/21/2014] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to investigate the functional outcomes of arthroscopic Bankart repair for recurrent shoulder instability in the setting of moderate glenoid bone defect ranging from 20% to 30% in patients with moderate to low functional demand. METHODS This study included 36 patients with unilateral recurrent instability and glenoid bone defects of 20% to 30% treated with arthroscopic stabilization. Glenoid bone loss was estimated on the en-face view of preoperative 3-dimensional computed tomography. Joint laxity was assessed clinically by use of the Beighton and Horan criteria, and patients were divided into 2 groups based on the presence of excessive joint laxity, group L (n = 13), or absence of excessive joint laxity, group N (n = 23). Functional assessments were performed with the patient-reported activity level; subjective shoulder value; Rowe score; and University of California, Los Angeles shoulder score. RESULTS The mean glenoid defect size was 25.1% (range, 20% to 29%), and the overall functional outcomes improved significantly after surgery. A return to greater than 90% of the premorbid activity level was reported by 72% of patients (26 of 36 patients), and patient satisfaction was 83% (30 of 36 patients). There was no significant difference in functional outcomes between groups L and N (subjective shoulder value, 85.0% for group L v 88.9% for group N, P = .397; Rowe score, 83.5 for group L v 92.8 for group N, P = .537; and University of California, Los Angeles shoulder score, 32.2 for group L v 31.9 for group N, P = .697). Recurrent instability occurred in 4 patients (11%), 3 patients in group L (3 of 13, 23%) and 1 patient in group N (1 of 23, 4%), but this difference was not statistically significant (P = .125). CONCLUSIONS Arthroscopic stabilization for recurrent shoulder instability in patients with moderate to low functional demand produced satisfactory outcomes despite the presence of moderate glenoid bone defects of 20% to 30%. For patients with excessive joint laxity, however, arthroscopic stabilization may not be reliable, with a recurrence rate of 23%. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
BACKGROUND The purpose of this study was to evaluate the association between the postoperative outcomes of anterior cruciate ligament (ACL) reconstruction and the anterior laxity of the uninjured knee. METHODS We retrospectively reviewed 163 patients who had undergone unilateral ACL reconstruction from January 2002 to August 2009. Patients were divided into three groups according to the anterior laxity of the contralateral, normal knee in 30° of knee flexion as measured with a KT2000 arthrometer exerting a force of 134 N: <5 mm for Group 1, 5 to 7.5 mm for Group 2, and >7.5 mm for Group 3. Anterior laxity of the uninjured knee was assessed preoperatively, and anterior laxity of the reconstructed knee was assessed at twenty-four months postoperatively. Anterior stability of the knee was also assessed with use of the Lachman and pivot-shift tests. Functional outcomes were assessed with the Lysholm score and the International Knee Documentation Committee (IKDC) score. RESULTS The three groups differed significantly with respect to the postoperative side-to-side difference in anterior laxity (p = 0.015), Lysholm score (p < 0.001), and IKDC subjective score (p < 0.001). The mean side-to-side difference in anterior laxity of the reconstructed knee was 2.1 ± 1.3 mm in Group 1, 2.2 ± 1.3 mm in Group 2, and 2.9 ± 1.4 mm in Group 3. The postoperative Lysholm score was 91.8 ± 4.5 in Group 1, 90.3 ± 5.5 in Group 2, and 85.4 ± 6.6 in Group 3. The postoperative IKDC subjective score was 89.3 ± 6.4 in Group 1, 87.9 ± 6.0 in Group 2, and 82.6 ± 8.2 in Group 3. Post hoc testing showed that Group 3 had significantly greater anterior laxity (p ≤ 0.039) and lower functional scores (p ≤ 0.001) compared with Groups 1 and 2. CONCLUSIONS Greater anterior laxity of the uninjured knee was associated with poorer stability and functional outcomes after ACL reconstruction. Excessive anterior laxity of the uninjured knee thus appears to represent a risk factor for inferior outcomes.

Abstract
BACKGROUND Although an anatomically placed graft in anterior cruciate ligament (ACL) reconstruction is reported to have a low risk of roof impingement, which may cause deterioration of the graft or an extension deficit, the incidence of roof impingement by these grafts has not been evaluated in hyperextensible knees. PURPOSE To evaluate the incidence of roof impingement by the native ACL in hyperextensible knees and to examine the risk of roof impingement by anatomic placement of the ACL graft in hyperextensible knees. STUDY DESIGN Controlled laboratory study. METHODS Twelve patients were selected for a hyperextensible knee group (group A), defined as having hyperextension of the knee of greater than 10°. Twelve patients were recruited to a normal extension knee group (group B) with normal extension of the knee of less than 5° of hyperextension. Magnetic resonance imaging (MRI) scans of the knee positioned in 30° of flexion and full extension were acquired from all patients. The shape of the native ACL at full extension was compared between the groups. A 3-dimensional (3D) bone model was created from the acquired 2D MRI scans. A virtual anatomic double-bundle ACL reconstruction in each patient and a virtual anatomic single-bundle reconstruction in the patients in group A were performed using the 3D MRI bone models. The volume of the overlap between the graft and roof was calculated to evaluate graft impingement in each instance. RESULTS The MRI scans showed posterior bowing of the native ACL in the group A knees. The simulated double-bundle ACL reconstruction showed that the overlapped volume was significantly greater in patients in group A than in patients in group B (P < .05). However, the overlap of the simulated single-bundle ACL reconstruction was significantly less than for the double-bundle ACL reconstruction (P < .05). CONCLUSION To reduce the risk of roof impingement by the graft, single-bundle ACL reconstruction with the graft placed at the center of the footprint might be the better method for patients with a hyperextensible knee than an anatomic double-bundle ACL reconstruction. CLINICAL RELEVANCE It is recommended that surgeons cautiously consider roof impingement after anatomic double-bundle ACL reconstruction in patients with a hyperextensible knee.

Abstract
Purpose In anterior cruciate ligament (ACL) injury, conventional adult reconstruction techniques have to face the potential risk of growth disturbance or angular deformities in skeletally immature patients. The aim of this study was to evaluate the clinical outcomes of ACL reconstruction by conventional transphyseal tunnel technique. Materials and Methods On a retrospective basis, we reviewed 25 skeletally immature patients; all the patients showed skeletal maturity at last follow-up, and the mean age was 16.4 years. The average injury to surgery interval was 12.6 months. Clinical outcomes were assessed at a mean of 74.4 months postoperatively using the Lysholm Knee Scoring Scale, the Tegner activity level, the International Knee Documentation Committee (IKDC), and plain radiographs. Results All the patients had undergone transphyseal reconstruction of ACL. The mean Lysholm score was 48.36 points preoperatively and 93.32 points postoperatively; the mean Tegner activity level was changed from 3.0 points to 5.6 points. The mean IKDC level was categorized as C preoperatively and changed to A postoperatively. Conclusions Our midterm outcome at an average 6 years after surgery was satisfactory without significant leg length discrepancies or abnormal alignment of the knee joint. Transphyseal reconstruction of ACL is a good treatment modality in the skeletally immature patient.

Abstract
PURPOSE The purposes of this study were (1) to determine normal anterior and posterior knee laxity in a healthy young adult (20-30 years old) Korean population, (2) to compare knee laxity between the male and female populations, (3) to investigate whether generalized joint laxity affects anterior and posterior knee laxity, (4) to determine side-side differences between right and left knees, and thus, to determine normal values of side-side differences. METHODS Normal values of anterior and posterior knee laxity were measured in 100 healthy volunteers (50 men and 50 women) aged between 20 and 30 years. Stress radiography using a Telos device was performed in 20 and 70° of knee flexion for 134N anterior and posterior loads. Anterior and posterior tibial displacements relative to the femur condyle were measured using a computerized system. RESULTS In the 100 subjects (200 knees), anterior knee laxity was greater at 20° of flexion with a mean of 4.9 ± 2.3 mm (P < 0.05) and posterior knee laxity was greater at 70° of flexion with a mean of 4.6 ± 2.7 mm (P < 0.05). The mean side-side difference was 1.4 ± 0.9 mm (range, -3 to +3). Women had greater anterior laxity (P < 0.05) than men at both 20 and 70° of flexion, but posterior laxity was not different (ns). Generalized joint laxity was greater in women compared to men (P < 0.05). Subjects with generalized joint laxity had greater laxity than normal populations in both 20 and 70° of flexion (P < 0.05). Side-side differences between right and left knees were not significantly different in women and men or between subjects with normal and generalized joint laxity (ns). CONCLUSIONS This study suggests that the Korean population exhibits a wide range of normal anterior and posterior knee laxity, but small side-side differences. Subjects with generalized laxity showed greater knee laxity than those without, but side-side differences were less than 3 mm in all subjects. Thus, clinical guideline that a side-side difference more than 3 mm of anterior knee laxity is abnormal can be applicable for the subjects with generalized laxity.

Abstract
Excessive joint laxity, or hypermobility, is a common finding of clinical importance in the management of musculoskeletal conditions. Hypermobility is common in young patients and in general is associated with an increased incidence of musculoskeletal injury. Hypermobility has been implicated in ankle sprains, anterior cruciate ligament injury, shoulder instability, and osteoarthritis of the hand. Patients with hypermobility and musculoskeletal injuries often seek care for diffuse musculoskeletal pain and injuries with no specific inciting event. Orthopaedic surgeons and other healthcare providers should be aware of the underlying relationship between hypermobility and musculoskeletal injury to avoid unnecessary diagnostic tests and inappropriate management. Prolonged therapy and general conditioning are typically required, with special emphasis on improving strength and proprioception to address symptoms and prevent future injury. Orthopaedic surgeons must recognize the implications of joint mobility syndromes in the management and rehabilitation of several musculoskeletal injuries and orthopaedic disorders.

Abstract
Generalized joint laxity is a genetically determined component of overall joint flexibility. The incidence of joint laxity in the overall population is approximately 5% to 20%, and its prevalence is higher in females. Recently it was noticed that individuals with generalized joint laxity are not only prone to anterior cruciate ligament injuries but also have inferior results after a reconstruction. Therefore, an anterior cruciate ligament reconstruction in patients with generalized laxity should be undertaken with caution due to the higher expected failure rate from the complexity of problems associated with this condition. It is also necessary to identify the risk factors for the injury as well as for the post operative outcome in this population. A criterion that includes all the associated components is necessary for the proper screening of individuals for generalized joint laxity. Graft selection for an anterior cruciate reconstruction in patients with ligament laxity is a challenge. According to the senior author, a hamstring autograft is an inferior choice and a double bundle reconstruction with a quadriceps tendon-bone autograft yields better results than a single bundle bone-patella tendon-bone autograft. Future studies comparing the different grafts available might be needed to determine the preferred graft for this subset of patients. Improved results after an anterior cruciate ligament reconstruction can be achieved by proper planning and careful attention to each step beginning from the clinical examination to the postoperative rehabilitation.

Abstract
UNLABELLED It generally is believed generalized joint laxity is one of the risk factors for failure of anterior cruciate ligament (ACL) reconstruction. However, no consensus exists regarding whether adverse effects on ACL reconstruction are attributable to joint-specific laxity or are related to the severity of generalized joint laxity. We therefore asked whether knee stability and functional outcomes would be related to joint-specific laxity and would differ according to the severity of generalized joint laxity. The Beighton and Horan criteria were used to assess joint laxity in 272 subjects. All elements are added to give an overall joint laxity score ranging from 0 to 5. Knee translation did not increase in proportion to the severity of the generalized joint laxity. Patients with scores less than 4 showed similar knee stability. When all variables, including the severity of generalized joint laxity, were considered, only hyperextension of the knee independently predicted knee stability and function. In patients with knee hyperextension, a bone-patellar tendon-bone autograft provided superior stability and function compared with a hamstring tendon autograft. Our data suggest knee hyperextension predicts postoperative stability and function regardless whether patients have severe generalized joint laxity. LEVEL OF EVIDENCE Level III, prognostic study.

Abstract
BACKGROUND Double-bundle anterior cruciate ligament (ACL) reconstruction has several potential advantages over single-bundle reconstruction with hamstring tendons. However, there are still controversies regarding tunnel placement in tibial and femoral attachments. HYPOTHESIS The macroscopically normal ACL consists of small bundles about 1 mm in diameter. Detailed observation of the divided smaller bundles will achieve better understanding of the tunnel placement in anatomic ACL reconstruction. STUDY DESIGN Descriptive laboratory study. METHODS This study used 20 cadaveric knees. The ACL was divided into anteromedial and posterolateral bundles, then separated into 10 small bundles of 2-mm diameters, with preservation of their attachment sites marked with color markers. The positional relationship between the femoral and tibial attachments of each small bundle was investigated. RESULTS A layered positional correlation of small bundles was found between the tibial and femoral attachments. Small bundles aligned in the anterior-posterior direction in the tibia corresponded to the bundles aligned in a high-low direction in the femur in flexion. The femoral attachment pattern was relatively similar in each specimen; however, the tibial attachment showed 2 patterns: an oblique type (12 of 20) and a transverse type (8 of 20). The posterior portion of the posterolateral bundle was separately attached to the medial and lateral portions of the tibial attachment. There was no fibrous insertion in the center of the posterior portion of the ACL tibial attachment in any specimen. In this bare area, there was fat tissue and vascular bundles. CONCLUSION Small bundles constituting the ACL showed a relatively layered arrangement between 2 attachments. The tibial attachment showed 2 patterns of oblique and transverse types, and the vascular bundles were located in the center of the posterolateral bundle. CLINICAL RELEVANCE The results of this study of the normal ACL will provide insights for surgeons when placing grafts during anatomic ACL reconstruction.

Abstract
BACKGROUND In a patient with generalized ligamentous laxity, the risk of instability is greater with a conventionally reconstructed anterior cruciate ligament. The purpose of this study was to compare the clinical outcome of anterior cruciate ligament reconstruction done with a double-bundle technique with use of a quadriceps tendon-bone autograft and that of a single-bundle reconstruction with use of a bone-patellar tendon-bone autograft in patients with generalized ligamentous laxity. METHODS The records of sixty-one patients who underwent anterior cruciate ligament reconstruction between June 2002 and October 2005 were evaluated. Thirty-two patients underwent a single-bundle reconstruction (group 1), and twenty-nine patients underwent a double-bundle reconstruction (group 2). Clinical outcomes were determined from data obtained before surgery and at the twenty-four-month follow-up visit. RESULTS Postoperatively, the mean side-to-side difference (and standard deviation) in anterior tibial translation, measured with use of a KT-2000 arthrometer, was greater for group 1 (3.37 +/- 1.76 mm; range, 1.00 to 8.00 mm) than for group 2 (2.03 +/- 1.11 mm; range, 0.00 to 3.50 mm) (p = 0.02). Three patients in group 1 had a grade-1+ pivot shift, while no patient in group 2 had an abnormal pivot shift. The mean score on the Hospital for Special Surgery knee ligament questionnaire was 90.8 in group 1 and 92.1 in group 2, and the mean Lysholm score was 89.4 in group 1 and 91.1 in group 2. CONCLUSIONS On the basis of the evaluation of ligamentous laxity measured by the KT-2000 arthrometer, a double-bundle anterior cruciate ligament reconstruction with use of a quadriceps tendon-bone autograft allows less anterior translation than does a single-bundle reconstruction with use of a bone-patellar tendon-bone autograft. However, we could not identify a significant difference in the functional outcome between the two techniques.

Comparison of single- and double-bundle anterior cruciate ligament reconstruction using quadriceps tendon-bone autografts. Arthroscopy 2009; 25:70-7. [PMID: 19111221 DOI: 10.1016/j.arthro.2008.09.004] [Citation(s) in RCA: 38] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2008] [Revised: 08/04/2008] [Accepted: 09/05/2008] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to evaluate and compare postoperative knee stability and functional scores between single- and double- bundle anterior cruciate ligament (ACL) reconstruction with the use of quadriceps tendon-bone autografts at a 2-year follow-up. METHODS The records of 59 patients who had ACL reconstruction between January 2005 and April 2006 were analyzed retrospectively. Twenty-eight patients had single-bundle reconstruction (group S) and 31 received double-bundle reconstruction (group D). Ligament stability was assessed with the Lachman and pivot-shift tests and a KT-2000 arthrometer. International Knee Documentation Committee (IKDC) and Lysholm scores were employed to evaluate the functional outcomes. RESULTS The postoperative mean side-to-side difference for group S was 2.64 mm and 1.79 mm for group D, a difference that was found to be statistically significant (P = .020). Regarding the pivot-shift test, 3 patients had grade 1+ and 1 patient had grade 2+ pivot-shift in group S, while no patients had abnormal pivot-shift in group D (P = .093). The patients who reported grade A or B on IKDC scores were 24 and 28 in group S and D, respectively (P > .1). On the questionnaire of the twisting activity, although statistical difference was not found between the groups, there was a trend toward more restriction in twisting activity in group S (P = .096). We found significant correlation between the twisting activity and instability questionnaire of the Lysholm score (Spearman coefficient, 0.737; P < .001). CONCLUSIONS Double-bundle ACL reconstruction using quadriceps tendon-bone autografts provide less laxity (1.79 mm) than single-bundle ACL reconstruction (2.64 mm) as measured by the KT-2000. However, we could not find any significant differences in the functional measurements between the 2 groups. LEVEL OF EVIDENCE Level III, retrospective comparative study.
