Abstract

Introduction

Anterior cruciate ligament reconstruction (ACLR) can be performed with a number of different autografts including all soft tissue quadriceps autograft. (QT). QT has several advantages including decreased donor site morbidity, reduced anterior knee pain and comparable revision rates compared to other autografts. The primary aim of this review was to assess all complications of QT in adult population.

Methodology

A systematic review of the literature was conducted on in accordance with the PRISMA guidelines using the online databases Medline and EMBASE. Clinical studies or reporting on soft tissue QT were included and appraised using the Methodological Index for Non-Randomized Studies (MINORS) tool.

Aims

The aim of this study was to compare patient-reported outcomes (PROMs) following isolated anterior cruciate ligament reconstruction (ACLR), with those following ACLR and concomitant meniscal resection or repair.

Methods

We reviewed prospectively collected data from the UK National Ligament Registry for patients who underwent primary ACLR between January 2013 and December 2022. Patients were categorized into five groups: isolated ACLR, ACLR with medial meniscus (MM) repair, ACLR with MM resection, ACLR with lateral meniscus (LM) repair, and ACLR with LM resection. Linear regression analysis, with isolated ACLR as the reference, was performed after adjusting for confounders.

Aims

There is limited information on outcomes of revision ACL reconstruction (rACLR) in soccer (association football) athletes, particularly on return to sport and the rate of additional knee surgery. The purpose of this study was to report return to soccer after rACLR, and to test the hypothesis that patient sex and graft choice are associated with return to play and the likelihood of future knee surgery in soccer players undergoing rACLR.

Methods

Soccer athletes enrolled in a prospective multicentre cohort were contacted to collect ancillary data on their participation in soccer and their return to play following rACLR. Information regarding if and when they returned to play and their current playing status was recorded. If they were not currently playing soccer, they were asked the primary reason they stopped playing. Information on any subsequent knee surgery following their index rACLR was also collected. Player demographic data and graft choice were collected from their baseline enrolment data at rACLR.

Abstract

Introduction

The study aims were to demonstrate rates, level, and time taken to RTP in elite sports after ACL reconstruction (ACL-R) and compare football and rugby.

Methods

A retrospective review of a consecutive series of ACL-R between 2005 and 2019 was undertaken. Patients were included if they were elite athletes and were a minimum of 2 years post primary autograft ACL-R. The outcomes measured were return to play (RTP), (defined as participation in a professional match or in national/ international level amateur competition), time to RTP after surgery, and RTP level (Tegner score).

Abstract. Introduction. Anterolateral procedures can reduce the risk of re-rupture after ACL reconstruction in high risk patients however, this effectiveness has never been evaluated in elite athletes. The purpose of this study was to evaluate the effectiveness of lateral extra-articular tenodesis in reducing revision rates in ACL reconstructions in elite athletes. Methodology. A consecutive cohort of elite athletes between 2005 and 2018 undergoing ACLR reconstruction with or without modified Lemaire lateral extra-articular tenodesis were analysed. A minimum of 2 years of follow-up was required. The association between the use of LET and ACL graft failure was evaluated with univariate and multivariate logistic regression models. Results. 455 elite athletes (83% male; 22.5±4.7 years) underwent primary ACL reconstruction with (n=117) or without (n=338) a LET procedure. Overall, 36 athletes (7.9%) experienced ACL graft failure including 32 (9.5%) reconstructions without a LET and 4 (3.4%) with a LET. Utilization of LET during primary ACL reconstruction reduced the risk of graft failure by 2.8 times with 16.5 athletes needing to be treated with LET to prevent a single ACL graft failure. Multivariate models showed that LET significantly reduced the risk of graft rupture (RR=0.325; p=.029) as compared to ACL reconstruction alone after controlling for age at ACL reconstruction and gender. Including graft type in the model did not significantly change the risk profile. Conclusion. The addition of LET in elite athletes undergoing primary ACL reconstruction reduced the risk of undergoing revision by 2.8 times

Abstract. Methodology. Prospective single-surgeon case-series evaluating patients undergoing surgery by this technique. 76 cases (mean age of 33.2 years) who had primary ACL reconstruction with BTB or quadriceps tendon with bone block, were divided into 2 matched groups (age, sex and type of graft) of 38 each based on the method of femoral fixation used (interference screw or adjustable cortical suspension). Patients were followed up clinically and using PROMS from NLR with EQ-5D, KOOS, IKDC and Tegner scores. Complications and return to theatre were noted. Paired two-tailed student t-tests and Chi-square tests were employed for statistical analysis. Results. At a mean follow-up of 82 months, peri-operative mean EQ-5D VAS, EQ-5D Index, KOOS, IKDC and Tegner activity scores showed significant improvement (p<0.05), but no significant difference between the two groups (p>0.05). Mean graft length and diameter was 77mm and 9.3 respectively. Mean interval from injury to surgery was 10.5 months. 18(23.7%) patients had associated meniscal tear with 73.3 % undergoing repair. 10 cases (13.2 %) returned to theatre including, MUA for arthrofibrosis (n=2) and intra-substance graft failure (n=2). 3 cases had to be converted to interference screw fixation due to the tightrope cutting through from the femoral bone block as a result of a technical pitfall. Conclusion. Primary ACL reconstruction using adjustable cortical suspension on femoral side for BTB or quadriceps bone-block tendon graft is a safe technique with added advantages of 360 degree bone ingrowth and no screw in the femoral tunnel

Abstract. Purpose. Since arthroscopic reconstruction of the anterior cruciate ligament (ACL) started, the use of peroneus longus grafts for primary ACL reconstruction (ACLR) was never thought of as there is very scant literature on it. So, our study aims to compare the functional outcome and complications in patients with ACL injury managed by ACLR with peroneus longus tendon (PLT) and hamstring tendons (HT) respectively. Materials and Methods. Patients with 16–50 years of either gender presenting with symptomatic ACL deficiency were admitted for arthroscopic single bundle ACLR and allocated into two groups (PLT and HT) operated and observed. Functional scores (IKDC and Lysholm score), clinical knee evaluation, donor site morbidity (AOFAS score) and thigh circumference were recorded preoperatively and at six months, one year post-operatively. The same post-op rehabilitation protocol was followed in both groups. Results. 194 patients (hamstring n=96, peroneus n=98) met the inclusion criteria. There were no significant differences between the pre-op, six months post-op and one-year postoperative score between the hamstring and peroneus longus groups in the IKDC (p=0.356) and Lysholm knee score (p=0.289). The mean for the AOFAS was 99.05±3.56 and 99.80±0.70 in the PLT and HT group respectively showing no statistical difference, with a significant improvement in thigh muscle wasting among the PLT group at final follow-up (p<0.001). Conclusion. We observed similar knee stability, functional outcome and no obvious donor site morbidity among both groups and recommend that a PL graft may be a safe, effective, and viable option for arthroscopic single bundle ACL reconstruction

The outcome following arthroscopic anterior cruciate (ACL) reconstruction is dependant on a combination of surgical and non-surgical factors. Technical error is the commonest cause for graft failure, with poor tunnel placement accounting for over 80% of those errors. A routine audit of femoral and tibial tunnel positions following single bundle hamstring arthroscopic ACL reconstruction identified apparent inconsistent positioning of the tibial tunnel in the sagittal plane. Intra-operative fluoroscopy was therefore introduced (when available) to verify tibial guide wire position prior to tunnel reaming. This paper reports a comparison of tibial interference screw position measured on post-operative radiographs with known tunnel position as shown on intra-operative fluoroscopic images in 20 patients undergoing routine primary ACL reconstruction between January and June 2009. Surgery took a mean of 5 minutes longer when intra-operative fluoroscopy was used. In 3/20 patients, fluoroscopy led to re-positioning of the tibial guide wire prior to tunnel reaming. The mean tibial tunnel position as indicated by the tunnel reamer was 41 +/− 2.7 % of the total plateau depth (range 37% to 47%). The mean position projected from the tibial screw on post operative radiographs was 46 +/− 9.2% (range 38% to 76%). A paired t-test showed a significant difference (p = 0.022) between true tunnel position and tibial screw position. 6/20 patients had post operative screw positions that were > 5% more posterior than the known position of the tibial tunnel. The position of the tunnel should be measured at its mid-point where this is evident. On most early radiographic images, the margins of the tunnel are not clear and therefore a line projected from the centre of the screw is used. This audit demonstrates the potential inaccuracy associated with this

Purpose. The aim of the present study was to investigate the relationship between generalised ligament laxity and requirement for revision ACL reconstruction. Materials and methods. 126 patients undergoing primary ACL reconstruction were included in the study along with 35 patients undergoing revision ACL surgery. 62 patients without any knee ligament injury formed an age and sex matched the control group. The Beighton score was used to quantify the ligamentous laxity in all cases with a score more than 4 classified as having generalised ligamentous laxity. The revision ACL patients were evaluated to identify technical errors at the time of the primary procedure or subsequent traumatic injury that could have contributed to primary graft failure. Results. The primary ACL surgery group was associated with an increased generalised ligamentous laxity compared to the control group and this was statistically significant (p < 0.05). Similarly the revision surgery group was also associated with increased generalised ligamentous laxity compared to the control group (p < 0.05). The revision ACL surgery group was also associated with increased generalised ligamentous laxity when compared to the primary ACL surgery group but this did not quite achieve statistical significance (p = 0.058). There was a subgroup within the revision cohort, who had a failure of the original surgery due to biological failure of the primary graft. The incidence of generalised ligament laxity in this group was significantly higher than the primary surgery group (p < 0.05). Conclusion. The findings of the study suggest a clear relationship between generalised ligamentous laxity and ACL injury. The study also highlights a link between generalised ligamentous laxity and requirement for revision ACL surgery. Based on the results of our study we feel that in the presence of GLL an autogenous graft may not be the best mode of reconstruction for either primary of revision ACL reconstruction. A case could be made for preferring allografts over autografts for these patients to reduce the rate of graft failure. Further prospective studies comparing allograft and autorgraft failure rates in patients undergoing primary and revision ACL are required to confirm our observations

Aims. Wales in collaboration with the Welsh Assembly Government, has attempted to start a national ligament register. Introduction. Norway is the lead in Europe for running a successful national quality knee ligament registry. As yet there is no UK wide registry encompassing all forms of knee ligament surgery. The issue has been discussed at previous society meetings, but no consensus has been reached. Method. A pilot study covering three NHS Trusts in South Wales was run between April 2010 and September 2010. Data is gathered prospectively on non-operatively treated and surgically treated knee ligament injuries performed in the regions. This data is recorded on the WKLR form which is then sent to the WKLR centre and entered onto a secure database. Four knee surgeons agreed to take part in the study, from three NHS Health Boards. The data is recorded at the time of the operation on a tick box form akin to that used by the NJR. The prospectively gathered data is stored at the central registry office in Princess of Wales Hospital Bridgend. Results. A total of 68 forms were returned to the registry, 58 Males and 10 Females, average age 30 and 35 years respectively. Four per cent of ACL ruptures were treated non-operatively. Sixty two (96%) ACL ruptures were reconstructed; 57 primary reconstructions; 3 revisions; 2 were multi-ligament injuries. The most common mechanisms of injury in females were basketball and football. Rugby was the most common mechanism for males. Six PCL injuries were reported, half (3) were reconstructed, all using allograft Achilles tendon. Of the fifty seven primary ACL reconstructions, twenty nine (47%) ACL reconstructions were recorded with no meniscal injury, thirty (53%) of ACL reconstructions had concomitant meniscal injury, which equates to 8% requiring repair (5 medial, 1 lateral) and 25 (43%) requiring meniscectomy for non-repairable tears (15 medial, 10 Lateral). Cartilage lesions were seen in 18 reconstructions (27%). Of these 2 (3%) had synthetic mosaic plasty. Four lesions (6%) had chondroplasty and the remaining 12 (18%) treatment was not required but noted. Conclusion. The WKLR, although in its infancy, has shown that a ‘National Quality Database’ of this type is feasible and will provide the necessary quality assurance demanded by this active young group of patients. The WKLR will provide an invaluable research tool for assessing and comparing outcomes of the various techniques, graft types, and fixation devices. Failing implants can be identified early. Under performing institutions can be identified, and performance can be compared to the national average. All of these aims are focused at improving patient safety, satisfaction and outcome

Aims

Anterior cruciate ligament (ACL) and multiligament knee (MLK) injuries increase the risk of development of knee osteoarthritis and eventual need for total knee arthroplasty (TKA). There are limited data regarding implant use and outcomes in these patients. The aim of this study was to compare the use of constrained implants and outcomes among patients undergoing TKA with a history of prior knee ligament reconstruction (PKLR) versus a matched cohort of patients undergoing TKA with no history of PKLR.

Patients and Methods

Patients with a history of ACL or MLK reconstruction who underwent TKA between 2007 and 2017 were identified in a single-institution registry. There were 223 patients who met inclusion criteria (188 ACL reconstruction patients, 35 MLK reconstruction patients). A matched cohort, also of 223 patients, was identified based on patient age, body mass index (BMI), sex, and year of surgery. There were 144 male patients and 79 female patients in both cohorts. Mean age at the time of TKA was 57.2 years (31 to 88). Mean BMI was 29.7 kg/m2 (19.5 to 55.7).

Aims

The aim of this study was to investigate the long-term clinical and radiological outcome of patients who suffer recurrent injuries to the anterior cruciate ligament (ACL) after reconstruction and require revision surgery.

Patients and Methods

From a consecutive series of 200 patients who underwent primary reconstruction following rupture of the ACL, we identified 36 who sustained a further rupture, 29 of whom underwent revision surgery. Patients were reviewed prospectively at one, two, seven, 15 and about 20 years after their original surgery. Primary outcome measures were the number of further ruptures, the posterior tibial slope (PTS), and functional and radiological outcomes. These were compared with a gender and age matched cohort of patients who underwent primary ACL reconstruction only.

Aims

Our aim was to perform a meta-analysis of the outcomes of revision anterior cruciate ligament (ACL) reconstruction, comparing the use of different types of graft.

Materials and Methods

A search was performed of Medline and Pubmed using the terms “Anterior Cruciate Ligament” and “ACL” combined with “revision”, “re-operation” and “failure”. Only studies that reported the outcome at a minimum follow-up of two years were included. Two authors reviewed the papers, and outcomes were subdivided into autograft and allograft. Autograft was subdivided into hamstring (HS) and bone-patellar tendon-bone (BPTB). Subjective and objective outcome measures were analysed and odds ratios with confidence intervals were calculated.

Aims. The aim of this study was to investigate the incidence, risk factors, and outcome of venous thromboembolism (VTE) following anterior cruciate ligament (ACL) reconstruction in a nationwide cohort. Patients and Methods. All ACL reconstructions, primary and revision, that were recorded in the Swedish Knee Ligament Register (SKLR) between 2006 and 2013 were linked with data from the Swedish National Board of Health and Welfare. The incidence of VTE was determined by entries between the day of surgery until 90 days postoperatively based on diagnosis codes and the prescription of anticoagulants. Risk factors, outcome, and the use of thromboprophylaxis were analyzed. Descriptive statistics with multivariate analysis were used to describe the findings. Results. The cohort consisted of 26 014 primary and revision ACL reconstructions. There were 89 deep venous thromboses (DVTs) and 12 pulmonary emboli (PEs) with a total of 95 VTEs (0.4 %). Six patients with a PE had a simultaneous DVT. The only independent risk factor for VTE was age greater than or equal to 40 years (odds ratio 2.31, 95% confidence interval 1.45 to 3.70; p < 0.001). Thromboprophylaxis was prescribed to 9461 patients (36%) and was equally distributed between those with and those without a VTE (37.9% vs 36.4%). All patient-reported outcome measures (PROMs) one and two years postoperatively were significantly lower in those with VTE. Conclusion. The incidence of VTE following ACL reconstruction is 0.4%, and the only significant risk factor is age. Patients with VTE had worse postoperative clinical outcome than patients without VTE. We recommend against the routine use of thromboprophylaxis, but it should be considered in older patients

Aims

To investigate the risk factors for progression of articular cartilage damage after anatomical anterior cruciate ligament (ACL) reconstruction.

Patients and Methods

A total of 174 patients who underwent second-look arthroscopic evaluation after anatomical ACL reconstruction were enrolled in this study. The graded condition of the articular cartilage at the time of ACL reconstruction was compared with that at second-look arthroscopy. Age, gender, body mass index (BMI), ACL reconstruction technique, meniscal conditions, and other variables were assessed by regression analysis as risk factors for progression of damage to the articular cartilage.

Aims

To examine the rates of hamstring graft salvage with arthroscopic debridement of infected anterior cruciate ligament (ACL) reconstruction as reported in the literature and discuss functional outcomes.

Materials and Methods

A search was performed without language restriction on PubMed, EMBASE, Ovid, CINAHL and Cochrane Register of Controlled Trials (CENTRAL) databases from their inception to April 2015. We identified 147 infected hamstring grafts across 16 included studies. Meta-analysis was performed using a random-effects model to estimate the overall graft salvage rate, incorporating two different definitions of graft salvage.

We reviewed 87 patients who underwent revision reconstruction of the anterior cruciate ligament. The incidence of meniscal tears and degenerative change was assessed and related to the interval between failure of the primary graft and revision reconstruction. Patients were divided into two groups: early revision surgery within six months of graft failure, and delayed revision. Degenerative change was scored using the French Society of Arthroscopy system.

There was a significantly higher incidence of articular cartilage degeneration in the delayed group (Mann-Whitney U-test, 53.2% vs 24%, p < 0.01). No patient in the early group had advanced degenerative change, compared to 9.2% of patients in the delayed group. There was no significant difference (Mann-Whitney U-test, p = 0.3) in the incidence of meniscal tears between the two groups.

We conclude that revision reconstruction should be carried out within six months of primary graft failure, in order to minimise the risk of degenerative change.

We report the clinical outcome and findings at second-look arthroscopy of 216 patients (mean age 25 years (11 to 58)) who underwent anterior cruciate ligament (ACL) reconstruction or augmentation. There were 73 single-bundle ACL augmentations (44 female, 29 male), 82 double-bundle ACL reconstructions (35 female, 47 male), and 61 single-bundle ACL reconstructions (34 female, 27 male).

In 94 of the 216 patients, proprioceptive function of the knee was evaluated before and 12 months after surgery using the threshold to detect passive motion test.

Second-look arthroscopy showed significantly better synovial coverage of the graft in the augmentation group (good: 60 (82%), fair: 10 (14%), poor: 3 (4%)) than in the other groups (p = 0.039). The mean side-to-side difference measured with a KT-2000 arthrometer was 0.4 mm (-3.3 to 2.9) in the augmentation group, 0.9 mm (-3.2 to 3.5) in the double-bundle group, and 1.3 mm (-2.7 to 3.9) in the single-bundle group: the result differed significantly between the augmentation and single-bundle groups (p = 0 .013). No significant difference in the Lysholm score or pivot-shift test was seen between the three groups (p = 0.09 and 0.65, respectively). In patients with good synovial coverage, three of the four measurements used revealed significant improvement in proprioceptive function (p = 0.177, 0.020, 0.034, and 0.026).

We conclude that ACL augmentation is a reasonable treatment option for patients with favourable ACL remnants.

The purpose of this study was to report the outcome of ‘isolated’ anterior cruciate ligament (ACL) ruptures treated with anatomical endoscopic reconstruction using hamstring tendon autograft at a mean of 15 years (14.25 to 16.9). A total of 100 consecutive men and 100 consecutive women with ‘isolated’ ACL rupture underwent four-strand hamstring tendon reconstruction with anteromedial portal femoral tunnel drilling and interference screw fixation by a single surgeon. Details were recorded pre-operatively and at one, two, seven and 15 years post-operatively. Outcomes included clinical examination, subjective and objective scoring systems, and radiological assessment. At 15 years only eight of 118 patients (7%) had moderate or severe osteo-arthritic changes (International Knee Documentation Committee Grades C and D), and 79 of 152 patients (52%) still performed very strenuous activities. Overall graft survival at 15 years was 83% (1.1% failure per year). Patients aged < 18 years at the time of surgery and patients with > 2 mm of laxity at one year had a threefold increase in the risk of suffering a rupture of the graft (p = 0.002 and p = 0.001, respectively). There was no increase in laxity of the graft over time.

ACL reconstructive surgery in patients with an ‘isolated’ rupture using this technique shows good results 15 years post-operatively with respect to ligamentous stability, objective and subjective outcomes, and does not appear to cause osteoarthritis.

Between 1993 and 1994, 891 patients underwent primary anterior cruciate ligament (ACL) reconstruction. A total of 48 patients had undergone bilateral ACL reconstruction and 42 were available for review. These patients were matched to a unilateral ACL reconstruction control group for gender, age, sport of primary injury, meniscal status and graft type. At 15-year follow-up a telephone interview with patients in both groups was performed. The incidence of further ACL injury was identified through structured questions and the two groups were compared for the variables of graft rupture or further ACL injury, family history of ACL injury, International Knee Documentation Committee (IKDC) subjective score and activity level.

There were 28 male and 14 female patients with a mean age of 25 years (13 to 42) at the time of first ACL injury. Subsequent further ACL injury was identified in ten patients (24%) in the bilateral ACL reconstruction study group and in nine patients (21%) in the unilateral ACL reconstruction control group (p = 0.794). The mean time from bilateral ACL reconstruction to further ACL injury was 54 months (6 to 103). There was no significant difference between the bilateral ACL reconstruction study group and the matched unilateral ACL reconstruction control group in incidence of further ACL injury (p = 0.794), family history of ACL injury (p = 0.595), IKDC activity level (p = 0.514), or IKDC subjective score (p = 0.824).

After bilateral ACL reconstruction the incidence of graft rupture and subjective outcomes were equivalent to that after unilateral ACL reconstructions.
