Single bundle ACL reconstruction with peroneus longus tendon graft: 2-years follow-up

Donor-site morbidity following arthroscopic anterior cruciate ligament reconstruction using peroneus longus tendon autograft

INTRODUCTION

Peroneus longus has proved to be a promising graft for ACL reconstruction due to its high tensile strength, and ease of harvesting. While multiple studies have assessed the functional outcomes of the knee after ACL reconstruction using peroneus longus autograft, we aimed to evaluated donor site morbidity among the Indian population.

MATREIALS AND METHODS

This was a prospective, longitudinal, descriptive study conducted at a tertiary care hospital. Preoperative AOFAS and Karlsson-Peterson scores were obtained, and patients were followed up after surgery for a period of 6-months using the same scoring systems and strength testing with a hand-held Chatillon MSE-100-M dynamometer. Pedobarographs were done using Diers Pedoscan Plantar Pressure Measurement System on a subset of seven patients.

RESULTS

20 patients participated in the study. Mean AOFAS and Karlsson-Peterson scores pre-operatively were 99.7 ± 1.34 and 98.5 ± 4.62 respectively. On completing 6- months of follow-up these scores were found to be 95.6 ± 9.43 and 88.75 ± 18.42 respectively. Deterioration of mean evertor strength was noted at all follow-ups compared to the opposite side. Static pedobarographs showed significant decreased in total surface area of contact and pressure over the posterior aspect of the operated side by 3-months which improved later at 6-months. Dynamic pedobarographs showed decreased mean average plantar pressure while walking on the operated side and significant increase in mean surface area of contact of the operated side (191.886±22.678 cm2) at 6-months of follow-up compared to the opposite side (184.471 ± 22.218 cm2). Five patients showed deviation of the point of maximum pressure while walking on the operated foot making it lateral to the COP with increased lateral plantar/ medial plantar pressure ratio.

CONCLUSION

While the use of peroneus longus tendon autografts in arthroscopic ACL reconstruction does not seem problematic on short-term subjective assessment, there is objective evidence in keeping with evertor weakness, weakness of first ray plantar flexion and possible ankle instability.

The Efficacy of Anterior Cruciate Ligament Reconstruction with Peroneus Longus Tendon and its Impact on Ankle Joint Function

OBJECTIVE

Peroneus Longus Tendon (PLT), a viable anterior cruciate ligament (ACL) graft, shares similar biomechanics, making it suitable for reconstruction. Controversy exists over whether PLT transplants affects the donor ankle joint. The purpose of this study was to examine the recovery of knee joint function following arthroscopic ACL restoration using autologous PLT and its influence on the donor ankle joint.

METHODS

A retrospective analysis was conducted on 65 patients with ACL rupture who underwent PLT graft reconstruction in our hospital from January 2016 to December 2021. A three-dimensional gait analysis of the bilateral knee and ankle joints was performed postoperatively using an Opti_Knee three-dimensional motion measurement and analysis system-Yidong Medical Infrared Motion Gait Analyzer. Knee function scores and changes in the range of motion of the bilateral knee and ankle joints were collected. The analysis of preoperative and postoperative joint function scores, bilateral knee and ankle mobility was performed by t-tests.

RESULTS

One year after surgery, the patients' International Knee Documentation Committee (IKDC) scores, Knee Injury and Osteoarthritis Outcome Scores (KOOSs), and Lysholm scores were significantly improved compared to preoperative scores, with statistically significant differences (p < 0.05). There was no statistical difference in the American Orthopedic Foot and Ankle Society (AOFAS) score of the donor ankle joint before and after surgery (p > 0.05). During different gait cycles, there was no statistical difference in knee joint mobility between the affected and healthy sides (p > 0.05), but there was a statistical difference in the inversion and eversion angle of the donor ankle joint during the support phase (p < 0.05).

CONCLUSION

ACL reconstruction using the PLT can yield satisfactory knee joint function. However, it does affect inversion and eversion in the donor ankle joint, necessitating postoperative exercises. Similar subjective function ratings for both operated and non-operated feet, despite increased inversion-eversion motion in the operated foot, may be influenced by the subjective nature and margin of error in the AOFAS Ankle-hindfoot score, along with the relatively small variation in ankle inversion-eversion angles.

Functional Outcome of Single-Bundle Arthroscopic Anterior Cruciate Ligament Reconstruction using Peroneus Longus Graft and Hamstring Graft: An Open-Label, Randomized, Comparative Study

Background This study investigates the functional outcomes of single-bundle arthroscopic anterior cruciate ligament (ACL) reconstruction, comparing the use of two distinct graft sources: peroneus longus (PL) graft and hamstring graft. The choice of graft material in ACL reconstruction is crucial for optimal postoperative results, and this study aims to contribute valuable insights into the comparative efficacy of these two graft types. Method This open-label randomized comparative study involved a carefully selected cohort of patients undergoing single-bundle arthroscopic ACL reconstruction. Participants were randomly assigned to either the PL graft group or the hamstring graft group. Surgical procedures were conducted using standardized techniques, and postoperative rehabilitation protocols were closely monitored. Functional outcomes, including range of motion, stability, and patient-reported measures, were assessed at predefined intervals to ensure comprehensive data collection. Results The study underscores significant demographic and clinical factors in ACL reconstruction outcomes. Participants were predominantly aged 17-30 years (58.33%) with a mean age of 29.27 years and exhibited a male predominance (80.56%). Common complaints included knee pain and instability, primarily due to falls from bikes (55.56%) or sports-related trauma (44.44%). Notably, PL grafts demonstrated advantages over hamstring grafts, with longer mean length (10.11 mm vs. 8.77 mm, p=0.0001) and shorter operation times. Visual analog scale (VAS), International Knee Documentation Committee (IKDC), and Tegner Lysholm scores show no significant differences between grafts over the period of time. There is no notable foot eversion weakness or significant donor site morbidity after the PL graft harvest. Hamstring graft cases exhibit a higher incidence of altered sensation and muscle atrophy, suggesting the potential benefits of PL grafts for improved surgical outcomes. Conclusions Graft comparisons favored PL grafts due to longer length, and functional outcome assessments between the two graft types. However, foot and ankle strength assessments revealed fluctuations in strength recovery with PL grafts, highlighting the need for tailored rehabilitation. Thigh circumference variations suggested potential muscle atrophy in the hamstring graft group, along with reported paresthesia in the ipsilateral proximal leg. In conclusion, PL grafts offer potential advantages for ACL surgery, but ongoing monitoring and specialized rehabilitation are crucial.

Clinico-radiological outcome of Arthroscopic Anterior Cruciate Ligament Reconstruction with Augmentation of Dehydrated Human Amnion Chorion Allograft Membrane using Peroneus Longus Autograft

Introduction

For many sportsmen, anterior cruciate ligament (ACL) tears are unfortunate but common injuries. Several growth factors, cytokine, chemokine, and protease inhibitors functions in stimulation of paracrine reactions in fibroblast, endothelial, and stem cells thereby promoting the tissue restorative processes. Augmented with dehydrated Human Amnion Chorion Membrane (dHACM) allograft reinforces the reconstructed ligament and aids in effective restoration.

Materials and methods

In this case control study 15 patients undertaking ACL reconstruction with tripled peroneus augmented dHACM (G1) were prospectively monitored up for a period of 8 months along with 15 control patients (G2) without dHACM augmentation. Clinical and radiological outcomes were analysed and assessed about effect of augmenting the peroneus longus graft using dHACM. Clinical analysis included pre-operative two, four, six, and eight months post-operative Tegnor-Lysholm score, and radiological analysis included the 6th month postoperative MRI signal-to-noise ratio (SNR) measurements by mean signal-value at femoral insertion, midsubstance and tibial insertion of ACL graft.

Results

Clinically, as a mean Lysholm score of all patients, they were revealed to be consecutively high in G1 than in Group 2 at four, six, and eight months. The signal-to-noise ratio from the MRI results showed majority having good healing in G1 group.

Conclusions

Based on 6-month MRI, an effective ligamentization (SNR<75) was noticed in 53.33% of patients in the dHACM allograft enhanced group on comparison with 33% in the controls. The overall results show that the augmentation of dHACM allograft to ACL reconstruction yields in good patient outcomes at post-operative follow-up.

Surgical Technique for Lateral Patellofemoral Ligament Reconstruction Using Bone Tunnels: A New Method

Medial patellar instability (lateral patellofemoral ligament tear) is a rare condition which is commonly associated with lateral release for lateral patellar instability. LPFL is a lateral stabilizer of the patellofemoral joint. Reconstruction of LPFL is necessary to provide stability to the patella-femoral joint in patients with instability. We describe a novel technique of trans-osseous reconstruction of LPFL to gain stability and have better graft incorporation. A doubled peroneus longus graft is inserted into the patellar tunnel and secured with an endo button on the anteromedial aspect of the patella; the other end is then inserted into the insertional point on the femur and secured with an interference screw. This is an easy, novel, and reproducible technique which can be used to reconstruct LPFL.

The role of peroneus longus (PL) autograft in the reconstruction of anterior cruciate ligament (ACL): A comprehensive narrative review

Background

Peroneus longus tendon (PLT) is a known graft utilised in the ligamentous reconstructions of knee. The current review was performed to analyze the available evidence regarding PLT in the arthroscopic anterior cruciate ligament (ACL) reconstruction.

Methods

A comprehensive search of literature was performed on March 1, 2023 using 5 databases (for manuscripts published between 2010 and 2023). All studies reporting ACL reconstruction with PL graft in adults ≥18 years were considered; and final studies were shortlisted based on specific exclusion criteria.

Results

The search identified 684 articles, among which 26 manuscripts were finally selected. PLT has been used in primary ACL reconstruction (ACLR), revision ACLR, ACLR in multiligamentous injuries and those at risk for anterior knee pain. The full-thickness PLT graft is variable in its dimensions with the mean size ranging between 7 and 8.8 mm (half-PLT grafts ≤8.1 mm). The ultimate strength of doubled PLT graft is significantly higher than native ACL and comparable to the quadrupled hamstring.There was statistically insignificant difference in the laxity and functional outcome of knee following ACLR with PLT, as compared with other autografts (p > 0.05). PLT harvest is associated with satisfactory clinical foot and ankle outcomes, as well as excellent regenerative ability. Overall, studies have demonstrated lower complications with PLT (p < 0.05).

Conclusion

The dimensions of harvested PLT graft are more consistent than HT. It has similar functional outcome and survival, as compared to other autografts. It also has lower risk for donor-site morbidity and lower complications than HT. PLT is a promising, alternative autograft choice in patients undergoing ACLR.

Functional Outcomes of Anatomic Single Bundle Primary ACL Reconstruction with Peroneus Longus Tendon (Without a Peroneal Tenodesis) Versus Hamstring Autografts

Objectives

There is a paucity of comparative studies on the Peroneus longus tendon versus conventional hamstring autograft use in primary single-bundle ACL reconstruction. To date, there are no studies that reported donor ankle functional outcomes when a peroneus longus graft is harvested without performing a tenodesis to peroneus brevis.

Methods

A single-center retrospective comparative study was undertaken to evaluate the functional outcomes (IKDC & Tegner-Lysholm scores) of primary isolated single bundle anatomic ACL Reconstruction with Peroneus Longus tendon (PL group) versus Hamstring (HT group) autografts. Further, an evaluation of donor ankle morbidity using the AOFAS score for the PL group and persistent anteromedial thigh pain and paraesthesia around the knee for the HT group was also performed.

Results

30 patients were evaluated in each group. The mean graft diameter was 8.61 +/- 0.66mm (HT) & 9.6 +/- 0.84mm (PL) and the mean graft length was 7.39cm (HT) & 7.86cm (PL) respectively. The mean IKDC scores were 58.2 (Pre-op) & 89.52 (1 year) for the HT group and 61.8 (Pre-op) & 90.9 (1 year) for the PL group respectively. The mean Tegner-Lysholm scores were 69.83 (Pre-op) & 91.96 (1 year) for the HT group and 70.66 (Pre-op) & 92.36 (1 year) for the PL group respectively.10% of the HT group had residual anteromedial thigh pain & 6.7% had paraesthesia at one-year follow-up. In the PL group, the mean AOFAS score was 96.37 +/- 2.49 at the end of one year. Two cases (6.66%) reported paraesthesia around the harvested site.

Conclusion

Peroneus longus tendon appears to be a better autograft choice than hamstrings for primary ACL reconstruction. Further, without a peroneal tenodesis, the functional outcomes of the donor ankle remained excellent.

Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction Using a Single Peroneus Longus Tendon Graft

The peroneus longus tendon seems a viable graft option for knee ligament reconstructions, with adequate biomechanical properties and low morbidity after harvesting. The objective of this article is to describe a combined anterior cruciate ligament and anterolateral ligament reconstruction technique using a single peroneus longus tendon graft harvested from the infra malleolar region to ensure sufficient length.

There is a Minimal Difference in Ankle Functional Outcomes After Peroneus Longus Harvest: Systematic Review and Meta-analysis

Importance

Recently, peroneus longus (PL) autograft as a graft choice for ligament surgeries have attracted interest due to studies showing good clinical outcomes and minimal donor site morbidity. There remain concerns related to these grafts, especially the potential impact on ankle functions.

Aims/Objective

The purpose of this review and meta-analysis is to summarize the available evidence for ankle functional outcomes after PL harvest. This will provide objective clinical evidence for surgical decision making.

Evidence Review

Cochrane, Embase, Medline, and Google Scholar were all searched for articles published between January 2001 and May 2021. For the aim of a systematic review, certain inclusion and exclusion criteria were adopted in accordance with PRISMA recommendations. The primary outcome measure was the assessment of ankle functional outcomes using validated instruments (such as AOFAS score, FADI score etc.).

Findings

A total of twelve studies representing pooled patient populations of 537 patients were included in this review. The average follow-up duration was 17 months (range; 6-32 months) across all studies. All twelve studies assessed AOFAS score and six studies also additionally assessed FADI score. The pooled mean outcomes measured showed a slight decrease in post-operative as compared to pre-operative AOFAS and FADI score (mean difference of AOFAS 1.92, 95% CI 1.021-3.123, p value < 0.05 and mean difference for FADI 1.50, 95% CI 0.561-2.445, p value < 0.05). Though statistically significant the magnitude of variance implies minimal clinical impact.

Conclusion and Relevance

This review and meta-analysis found that PL autograft harvest leads to statistically significant but minimal impact on ankle functional outcomes. This, in conjunction with various studies on ankle parameters after PL harvest, shows that PL harvest leads to minimal impact on ankle outcomes and function.

Complications of peroneus longus tendon harvesting: a retrospective review of 82 cases

OBJECTIVE

Peroneus longus tendon (PLT) has become a reliable autologous graft option for various ligament reconstructions. But there are potential risks and complications associated with its use as a graft. This retrospective study aimed to examine the complications and donor site morbidity following PLT harvesting.

PATIENTS AND METHODS

A retrospective review was performed on an institutional digital patient database, and all patients who underwent ligament reconstruction using PLT autograft were identified. Intraoperative, early, and late complications were reviewed using digital patient notes and patients underwent a complete physical examination during their final follow-up. Ankle function was assessed using the AOFAS score, and manual ankle muscle testing was performed on both sides. Sural nerve iatrogenic injury was evaluated with a dermatomal light touch examination. Cosmetic satisfaction due to incision scar and footwear complaints were also assessed.

RESULTS

82 patients (74 male, eight female) with a mean age of 31.9 ± 10.4 years (range, 16-66) were included in the final analysis. The mean follow-up time was 46.6 ± 30.3 months (range, 6-109). The mean AOFAS score for the donor side was 98.7 ± 3.3 (range, 87-100), and the contralateral side score was 100, with manual muscle testing graded as 5 in all movements and similar to the contralateral side. Fifteen patients (18.3%) had hypoesthesia over the dorsolateral aspect of the foot distal to the incision scar, two patients (2.4%) had hyperalgesia over the distal incision scar, and one patient (1.2%) had mild ankle instability. There were two cases (2.4%) of compartment syndrome, both of which were treated with fasciotomy and had complete regression of symptoms after 5 days. One patient (1.2%) had a transient peroneal nerve injury and foot drop that resolved in the sixth month.

CONCLUSIONS

The results of this retrospective study suggest that harvesting the PLT is associated with a high rate of complications and donor site morbidity. The most common complication was hypoesthesia around the lateral side of the foot, although the ankle functions were not affected significantly. Two cases of compartment syndrome and one transient peroneal nerve injury were observed. Care should be taken while harvesting PLT autograft, and it should be kept in mind that peroneal nerve injury might occur.

Earlier Return to Sports, Reduced Donor-Site Morbidity with Doubled Peroneus Longus Versus Quadrupled Hamstring Tendon Autograft in ACL Reconstruction

Background

Graft choice for anterior cruciate ligament reconstruction (ACLR) has been evolving. The peroneus longus tendon (PLT) has been seen as a suitable choice for ACLR, providing comparable results to those of hamstring tendon (HT) autograft, but its clinical relevance in terms of return to sports, to our knowledge, has not been studied.

Methods

Two hundred and thirty-two patients who sustained an isolated ACL injury were enrolled and underwent ACLR using doubled PLT autograft or quadrupled HT autograft; 158 were followed for 24 months. Functional scores (International Knee Documentation Committee [IKDC] and Tegner-Lysholm scores) were assessed preoperatively and at 3,6, 12, and 24 months postoperatively. Graft diameter and graft harvesting time were measured intraoperatively. Donor-site morbidity was evaluated using subjective evaluation. Time to return to sports in both groups was compared.

Results

The mean diameter of PLT autograft was significantly larger than that of HT autograft, and the mean graft-harvesting time was less (p < 0.001). Patients in the PLT group returned to sports a mean of 34 days earlier than those in the HT group (p < 0.001) and had a lower rate of donor-site morbidity and, at 6 months, better patient-reported outcomes at the knee (p < 0.001). There were no significant differences between the groups in the rate of graft rupture or in IKDC and Tegner-Lysholm scores at the 24-month follow-up.

Conclusions

PLT is a suitable autograft for ACLR in terms of graft diameter and graft-harvesting time and may offer athletes an earlier return to sports related to better outcomes at 6 months of follow-up. HT autograft was associated with increased thigh weakness. Both grafts, however, performed similarly at 24 months postoperatively.

ACL Reconstruction in a Poliotic Limb with Peroneus Longus Graft

Introduction

Prevalence of polio was very high in India before its eradication, with a number of people living with its residual effects. Anterior cruciate ligament (ACL) injury is the most common knee injury. To the best of our knowledge, this is the first report in literature presenting ACL injury in a poliotic limb and its management.

Case Report

A 30-year-old male with poliotic limb and equinovarus deformity presented with ACL injury to the same limb. ACL reconstruction was done using Peroneus longus graft. Postoperatively patient was gradually returned to preinjury activity levels.

Conclusion

ACL tears in a poliotic limb can be a challenging case. Proper preoperative planning and anticipation of problems can help in managing the case with a good outcome.

Comparison of Functional Outcomes of an Anterior Cruciate Ligament (ACL) Reconstruction Using a Peroneus Longus Graft as an Alternative to the Hamstring Tendon Graft

Background Ever since the arthroscopic reconstruction of the anterior cruciate ligament (ACL) has begun, the use of the peroneus longus (PL) graft for primary ACL reconstruction (ACLR) has never been thought of. There is very little literature on it. Hence, our study aims to compare the functional outcomes, knee stability, donor site morbidity, and assessment of thigh muscle wasting in patients with ACL injury managed by arthroscopic single bundle reconstruction with peroneus longus tendon (PLT) and hamstring tendons (HT), respectively. Methods All adults aged 16-50 years of either gender presenting with symptoms of symptomatic ACL deficiency were admitted for arthroscopic single-bundle ACLR and allocated into two groups (peroneus longus and hamstring tendon). Functional scores (International Knee Documentation Committee (IKDC), Lysholm score), clinical knee evaluation (anterior drawer, Lachman, and pivot shift test), donor site morbidity (American Orthopedic Foot and Ankle Society ankle hindfoot score (AOFAS)), and thigh circumference were recorded preoperatively and at six months and one year postoperatively. The same post-op rehabilitation protocol was followed in both groups. Results One hundred and ninety-four patients (hamstring n = 96, peroneus n = 98) met the inclusion criteria. There were no significant differences between the preoperative, six-month postoperative, and one-year postoperative scores 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 groups, 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 and functional outcomes and no obvious donor site morbidity among both groups. These patients also had better responses to physiotherapy in recovering from their thigh muscle wasting. So, we can recommend that a PL graft can be a safe, viable, and effective option for usual arthroscopic single-bundle ACL reconstruction.

A prospective study of arthroscopic primary ACL reconstruction with ipsilateral peroneus longus tendon graft: Experience of 439 cases

Anterior cruciate ligament (ACL) tears are frequent ligamentous injuries that necessitate reconstruction in many cases. The patellar tendon and the hamstring tendon are the most frequently utilized autografts for reconstruction. However, both have certain disadvantages. We hypothesized that the peroneus longus tendon would be an acceptable graft for arthroscopic ACL reconstruction. The aim of this study is to determine whether a peroneus Longus tendon transplant is a functionally viable option for arthroscopic ACL reconstruction without compromising donor ankle activity. In this prospective study 439 individuals aged between 18 to 45 years, who underwent ACL reconstruction using ipsilateral Peroneus longus tendon autograft were observed. The injury to the ACL was initially assessed by physical examinations and further confirmed by magnetic resonance imaging (MRI). The outcome was assessed at 6, 12, and 24 months after the surgery using Modified Cincinnati, International Knee Documentation Committee (IKDC), and Tegner-Lysholm scores. The donor ankle stability was evaluated using foot and ankle disability index (FADI) and AOFAS scores, as well as hop tests. Significant (P < .001) improvement in the result of the IKDC score, Modified Cincinnati, and Tegner-Lysholm score was observed at the final follow-up. The Lachman test was mildly (1+) positive only in 7.70% of cases, the anterior drawer became negative in all cases, and the pivot shift test was negative in 97.43% of cases at 24 months after the surgery. FADI and AOFAS scores for donor's ankle functional assessment were impressive, as were single hop test, triple hop test, and cross over hop test results at 2 years. None of the patients had any neurovascular deficit. However, 6 cases of superficial wound infection were observed, 4 at the port site and 2 at the donor site. All resolved after appropriate oral antibiotic therapy. The peroneus longus tendon can be considered a safe, effective, and promising graft of choice for arthroscopic primary single-bundle ACL reconstruction because it has a good functional outcome and impressive donor ankle function after surgery.

Peroneus Longus Tendon Autograft versus Hamstring Tendon Autograft in Anterior Cruciate Ligament Reconstruction: A Comparative Study with a Mean Follow-up of Two Years

BACKGROUND

Peroneus longus tendon can be a suitable alternative autograft for anterior cruciate ligament reconstruction (ACLR). The present study aimed to compare the clinical outcome and donor site morbidity in ACLR using peroneus longus tendon autograft versus hamstring tendon autograft.

METHODS

In a comparative cross-sectional study, ACLR was performed with quadrupled hamstring tendon autograft in 65 patients between 2017 and 2018, and in another group, peroneus longus tendon autograft was used for ACLR in 65 patients between 2018 and 2019. The same surgical technique, fixation method, and postoperative protocol were used in both groups. The knee functional outcomes were assessed according to the Lysholm score and the International Knee Documentation Committee scale at preoperative and at the end of at least 2 years after the procedure. Moreover, graft diameter was measured intraoperatively. Thigh circumference, the American Orthopedic Foot and Ankle Score (AOFAS), The Foot & Ankle Disability Index (FADI), and ankle range of motion (ROM) were used to evaluate ankle donor site morbidities.

RESULTS

A total of 130 patients (65 patients in each group) were evaluated with a minimum follow-up of 2 years (range 24-31 months). Both groups showed no significant differences in clinical outcomes and knee stability. The peroneus longus graft diameter was significantly larger than the hamstring diameter (P<0.001). Assessment of AOFAS, FADI, and ankle ROM showed no apparent ankle joint dysfunction in the peroneus longus tendon group.

CONCLUSION

Faster knee extensions, less anteromedial knee pain, and thigh hypotrophy were observed in peroneus longus tendon patients. Peroneus longus tendon autograft can be an appropriate autograft for ACLR due to its strength, larger graft diameter, and avoiding potential complications of hamstring autograft obtained from the knee region.

Is Peroneus longus autograft a better alternative to the Hamstring autograft for anterior cruciate ligament reconstruction? – A randomised control study

Purpose

The anterior cruciate ligament in the knee is commonly prone to injuries. Reconstruction of this ligament with hamstring tendon has been time-tested but peroneus longus autograft is also gaining popularity. However, very limited literature is available comparing the two grafts. This study aims to compare the functional outcome and donor site morbidity between hamstrings and peroneus longus autograft in anterior cruciate ligament reconstruction.

Methods

A prospective randomised study was conducted on 45 patients, who underwent anterior cruciate ligament reconstruction. Patients were assigned into Hamstring group and the Peroneus longus group. Functional outcome was assessed using Lysholm score and Modified Cincinnati scores for the knee joint and American Orthopedics Foot and Ankle Scoring for ankle joint. Donor site morbidity was assessed by measuring flexion and extension strength of the knee and plantar flexion and eversion strength of the ankle by handheld dynamometer preoperatively and postoperatively at 6 months and 1 year follow up.

Results

Functional outcome of the knee showed significant improvement in peroneus longus group (p-value 0.002) compared to hamstring group. Even though there was minimal reduction in functional outcome of the ankle at 6 months follow-up in peroneus longus group, it improved at one year follow-up. While assessing the donor site morbidity at the knee joint, knee flexion strength showed improvement in the group (p-value 0.02) but reduced in the hamstring group where the hamstring tendon was harvested. Knee extension strength in the hamstring group scored marginally better than the peroneus longus group, which was not statistically significant (p-value 0.5).

Conclusion

Autologous peroneus longus tendon can be used as a graft of choice in anterior cruciate ligament reconstruction which showed promising results without compromising on the ankle function. Its usage as an alternative source of the graft may be more useful in multi-ligament injuries of the knee joint.

Low to moderate risk of nerve damage during peroneus longus tendon autograft harvest

PURPOSE

This study aims to evaluate the proximity of the tendon stripper to both the peroneal and sural nerves during peroneus longus tendon (PLT) autograft harvesting.

METHODS

Ten fresh-frozen human cadaveric lower extremities were used to harvest a full-thickness PLT autograft using a standard closed blunt-ended tendon stripper. The distance to the sural nerve from the PLT (at 0, 1, 2 and 3 cm proximal to lateral malleolus (LM), and the distance to the peroneal nerve and its branches from the end of the tendon stripper were measured by two separate observers using ImageJ software.

RESULTS

The average distance from the PLT to the sural nerve increased significantly from 0 to 2 cm proximal to LM. The average distance to the sural nerve at the LM was 4.9 ± 1.5 mm and increased to 10.8 ± 2.4 mm (2 cm proximal to LM). The average distance from the tendon stripper to the deep peroneal nerve was 52.9 ± 11.4 mm. The average distance to the PLT branch of peroneal nerve was 29.3 ± 4.2 mm. The superficial peroneal nerve, which coursed parallel and deep to the tendon stripper, was on average 5.2 ± 0.7 mm from the end of the stripper. No transection injuries of the nerves were observed in any of the ten legs after harvesting.

CONCLUSION

This cadaver study found during a full-thickness PLT harvest, the distances between the tendon stripper and the nerves were greater than 5 mm with an initial incision at 2 cm proximal to LM which is recommended.

Comparing the Stiffness of Peroneus Longus Tendon Versus Hamstrings in Anterior Cruciate Ligament Reconstruction: A Biomechanical Study

Background: The use of autografts originating from either hamstring tendons or peroneus longus tendons is a surgical option in anterior cruciate ligament (ACL) reconstruction. Objectives: This research aimed to compare the tensile strength between the hamstring tendon and the peroneus longus tendon in ACL reconstruction. The hypothesis of this study was: Peroneus longus grafts have tensile strength equal to hamstring grafts based on living donor patients. Methods: This cross-sectional study was a biomechanical study examining means and standard deviations (SD) by comparing the tensile strength of peroneus longus tendons and hamstring tendons when used as autograft donors in ACL reconstruction. Results: In this study, 51 patients with reconstructive ACL were enrolled. The mean diameter of the hamstring tendon was 7.86 with SD ± 0.69, while the mean diameter of peroneus longus tendon was 7.67 with SD ± 0.63. The mean diameter of the peroneus longus graft was not significantly different. The mean displacement on the hamstring tendon was 2.44 with SD ± 0.42, while the peroneus longus tendon was 2.06 with SD ± 0.14. The peroneus longus tendon had significantly more tensile strength compared to the hamstring tendon. Conclusions: Diameter of the peroneus longus graft was not significantly different from the hamstring graft. However, the peroneus longus graft had more tensile strength than the hamstring graft based on living donor patients.

Prediction of peroneus longus graft diameter for anterior cruciate ligament reconstruction by inframalleolar harvest and from anthropometric data

BACKGROUND

The literature is gradually drifting towards a graft of larger diameter for successful ACL reconstruction. There is no published literature regarding the anthropometric predictors for the diameter of the peroneus longus tendon (PLT) graft obtained in ACL reconstruction through the inframalleolar approach.

METHODS

Fifty-two patients were finally evaluated for anthropometric parameters to predict quadrupled PLT graft diameter in ACL reconstruction using the inframalleolar technique. Intraoperative quadrupled PLT graft diameter was correlated to the patient's anthropometric data such as age, height, weight, duration of injury, and BMI. We used regression analysis in a stepwise manner to ascertain anthropometric indices associated with the graft diameter.

RESULTS

This study included 46 males and six females. Mean age was 28.2 ± 7.4 years, mean height was 172.7 ± 2.8 cm, mean weight was 75.6 ± 3.4 kg, mean BMI was 25.3 ± 0.9 kg/m², mean duration of injury was 9.2 ± 3.9 months, and mean graft diameter was 9.3 ± 0.4 mm. Positive correlation with graft diameter was found only with height (r = 0.6, P < 0.01) and weight (r = 0.4, P < 0.01). On analysing through linear regression, height and weight had significant association with graft diameter, and we formulated the following prediction equation: PLT graft diameter (mm) = 0.083 × height (cm) + 0.011 × weight (kg) -5.854.

CONCLUSION

Patients' characteristics, including height and weight, have a significant correlation with quadrupled PLT graft diameter and the average diameter of graft is > 9 mm through this approach.

Peroneus longus tendon autograft has functional outcomes comparable to hamstring tendon autograft for anterior cruciate ligament reconstruction: a systematic review and meta-analysis

PURPOSE

This review aimed to assess whether peroneus longus tendon (PLT) autograft would have comparable functional outcomes and graft survival rates when compared to hamstring tendon (HT) autograft for anterior cruciate ligament (ACL) reconstruction.

METHODS

PubMed, Web of Science, Cochrane Library, Ovid (MEDICINE), and EMBASE databases were queried for original articles from clinical studies including the keywords: ACL reconstruction and PLT autograft. Studies comparing PLT autograft versus HT autograft were included in this analysis and the following data were extracted from studies meeting the inclusion criteria: graft diameter, functional outcomes (Tegner activity scale, Lysholm score, and International Knee Documentation Committee (IKDC) subjective score), knee laxity (Lachman test), and complications (donor site pain or paresthesia, graft failure). Besides, the American Orthopaedic Foot and Ankle Society (AOFAS) scale and the Foot and Ankle Disability Index (FADI) pre-operation and at last follow-up were also compared among patients using PLT autograft. Meta-analysis was applied using Review Manager 5.3 and p < 0.05 was considered statistically significant.

RESULTS

Twenty-three studies including 925 patients with ACL reconstruction met inclusion criteria. Of these, 5 studies included a direct comparison of PLT autograft (164 patients) versus HT autograft (174 patients). No significant difference was observed between PLT and HT autografts for Tegner activity scale, Lachman test, donor site pain, or graft failure. However, PLT groups demonstrated better Lysholm score (mean difference between PLT and HT groups, 1.55; 95% CI 0.20-2.89; p = 0.02) and IKDC subjective score (mean difference between PLT and HT groups, 3.24; 95% CI 0.29-6.19; p = 0.03). No difference of FADI was found (n.s.) but AOFAS was slightly decreased at last post-operative follow-up for patients with PLT autograft compared with pre-operative scores (mean difference of 0.31, 95% CI 0.07-0.54, p = 0.01).

CONCLUSION

PLT autograft demonstrated comparable functional outcomes and graft survival rates compared with HT autograft for ACL reconstruction. However, a slight decrease in AOFAS score should be considered during surgical planning. Hence, the PLT is a suitable autograft harvested outside the knee for ACL reconstruction to avoid the complication of quadriceps-hamstring imbalance which can occur when harvesting autografts from the knee.

Anterior Half of the Peroneus Longus Tendon Combined with Semitendinosus and Gracilis Tendons for Anterior Cruciate Ligament Reconstruction: An Athlete Case Report

In clinical practice, it is observed that the hamstring tendon graft, despite being first choice in knee ligament reconstruction, may not present adequate size. Therefore, it becomes necessary to search for other graft alternatives. In this context, the peroneus longus tendon arises as an option to replace or complement other grafts. The surgeon can opt to use the tendon in its totality or only its anterior half, presenting adequate length, diameter, and biomechanics, without major repercussions for the donor site. In this study, we report a case of an athlete in which the autologous hamstring tendon graft did not present the adequate diameter for anterior cruciate ligament reconstruction. It was, then, necessary to use the anterior half of the peroneus longus tendon.

Posterior cruciate ligament reconstruction with peroneus longus tendon versus hamstring tendon: a comparison of functional outcome and donor site morbidity

PURPOSE

This study aimed to evaluate the differences in clinical outcome and donor site morbidity between the Peroneus Longus Tendon (PLT) and Hamstring Tendon (HT) in single-bundle Posterior Cruciate Ligament (PCL) reconstruction.

METHODS

Patients with an isolated PCL injury underwent single-bundle PCL reconstruction using consecutive sampling. Patients were allocated into two groups (PLT and HT) and prospectively observed. The tendon graft diameter was measured intraoperatively. Functional scores (IKDC, Lysholm, and modified Cincinnati scores) were recorded preoperatively and 2 years postoperatively. The thigh circumference and functional score according to the Foot and Ankle Disability Index (FADI) and American Orthopedic Foot and Ankle Society (AOFAS) were recorded to evaluate the morbidities in the ankle.

RESULTS

Fifty-five patients (hamstring n = 27, peroneus n = 28) met the inclusion criteria. The diameter of the PLT graft (8.2 ± 0.6 mm) was comparable to that of the HT graft (8.3 ± 0.5 mm). Both groups had excellent postoperative knee functional outcome scores. The mean AOFAS and FADI scores were excellent, with no difference in thigh circumference between the groups.

CONCLUSION

PLT is a good choice as a graft in PCL reconstruction at the 2-year follow-up, with minimal donor site morbidity.

Insufficient evidence to support peroneus longus tendon over other autografts for primary anterior cruciate ligament reconstruction: a systematic review

IMPORTANCE

Graft choice for anterior cruciate ligament reconstruction (ACLR) remains a subject of interest among orthopaedic surgeons because no ideal graft has yet been found. Peroneus longus tendon (PLT) has emerged as an alternative autograft for reconstruction in kneeling populations and in simultaneous anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries.

OBJECTIVE

To evaluate the current evidence on the outcome of primary ACLR with PLT autograft in adults and donor ankle morbidity, in addition to determining the average PLT graft dimensions from published studies.

EVIDENCE REVIEW

Two independent reviewers searched PubMed, CENTRAL, EMBASE, Scopus and Virtual Health Library databases using the terms "anterior cruciate ligament," "peroneus longus" and "fibularis longus" alone and in combination with Boolean operators AND/OR. Studies evaluating clinical and stability outcomes, graft-donor ankle morbidity and graft dimensions of PLT in ACLR were included. Methodological quality was assessed using the Modified Coleman Methodology Score (mCMS). A narrative analysis is presented using frequency-weighted means wherever feasible. Publication bias was assessed using the ROBIS tool.

FINDINGS

Twelve articles with intermediate-level methodological quality were included. Eight studies assessing the clinical and stability outcomes of reconstruction with PLT showed satisfactory outcomes, similar to those of hamstring tendons (HT). No studies assessed anterior knee pain as an outcome. Six studies evaluated the graft-donor ankle morbidity using general functional foot and ankle scores and non-validated tools, showing favourable outcomes. Nine studies assessed PLT graft diameter, revealing grafts consistently larger than 7 mm among the different preparation techniques, which is comparable with reports of HT grafts.

CONCLUSIONS AND RELEVANCE

The clinical and stability outcomes of ACLR with different PLT autograft preparation techniques are comparable with those of HT during short-term follow-up; however, there is insufficient evidence to support its use in the populations that motivated its implementation. Thus, stronger evidence obtained with the use of validated tools reporting negligible donor-graft ankle morbidity after PLT harvesting is required prior to recommending its routine use, despite the consistency of its dimensions.

Comparison of the effectiveness of autologous grafts for anterior cruciate ligament reconstruction: A protocol for an overview of systematic review and network meta-analysis

BACKGROUND

Anterior cruciate ligament rupture is a common motor system injury, and the most effective treatment is anterior cruciate ligament reconstruction (ACLR). Choosing the right graft is an important factor to ensure the success of the surgery. Current research shows that the clinical effect of autologous ligaments is better than that of allogeneic ligaments and artificial ligaments. However, there are differences between the autogenous ligaments, and how to choose them is still controversial. This study evaluated the published systematic reviews on the efficacy of different autologous ligament grafts in ACLR, and based on this, conducted a network meta-analysis of related randomized controlled trials.

METHODS

We searched 8 international and Chinese databases including PubMed, Embase, Web of Science, and Cochrane Library. The methodological quality of systematic reviews will be evaluated by Assessing the Methodological Quality of Systematic Reviews-2 (AMSTAR2) measurement tool. Cochrane's risk of bias tool will be used to assess the risk of bias of included randomized controlled trials, and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach will be used to evaluate the evidence quality. Network meta-analysis will be applied to evaluate the therapeutic effect of different autologous grafts. The main outcome measures are IKDC score, clinical failure rate, Lachman test, Lysholm score, and the incidence of complications. Odds ratio and its 95% confidence interval will be used to synthesize the dichotomy results, while the mean difference and 95% confidence interval of continuous variables will be used for continuous variables.

RESULTS

This study will provide comprehensive evidence for the application of autologous grafts in ACLR.

CONCLUSION

The results of this study will help clinicians make appropriate decisions.
