“Technique, Technique, Technique”, although Dr David Hungerford quoted the above for arthroplasty surgery, the same applies to Arthroscopy. Surgical technique and skill are unique to Arthroscopy almost as if it is a distinct area of expertise. No other subspecialty of orthopaedics has such minimal overlap with general orthopaedics, in terms of surgical techniques. One of the major goals of Asian Journal of Arthroscopy (AJA) is propagation of arthroscopy techniques. ‘Training by Publication’ is one the founding pillars of AJA. We want to bring the best techniques and procedures to our readers. These techniques will be in form of articles, pictograms and videos with basic premise of ease of learning. The readers should be able to understand the principles of the surgery, the critical steps and also learn new tips and tricks. They should be able to execute steps on the surgery and possibly embark on the learning curve to master the technique. Although more work is needed in terms of envisioning the formats of the article, this remains the mail goal of AJA and in times to come we would look for ways and means to do this more effectively. Currently the Journal has a technical note/video technique section with guidelines to submit a video article. We will also be running pictograms or Photo-articles which will be more pictures and less text (something like a comic strip but with much more smiles for arthroscopy surgeons!). ArthroMedia is a special section on the AJA website which will host multiple media items like videos, powerpoints, PDF and other documents related to surgical skills and surgeries. This will be compiled from contributions of editorial board, reviewers board, authors and also from our readers. This section will be open for submission to all and will compile the best training content. We invite all of you to submit your content to ArthoMedia and help us build this portal.

Why the new Journal when there are already existing journals of Arthroscopy?
There are two main reasons; to produce a body of literature that is clinically relevant and to make this knowledge freely accessible to all. Journals have shown trend to move towards a more rigid framework of scientific publications, meanwhile losing the mail focus of scientific publications. Journals are meant to directly influence and improve patient care. Charging for downloading articles imposes another limitation on dispersion and use of knowledge. AJA intends to counter these two issues by creating a journal that is intelligent, interactive, and clinically relevant and at the same time completely Open Access. The entire format of the Journal will be one of ‘Integration’ with basic science, molecular research, clinical trials, clinical research, case based discussion, evidence based medicine, expert opinion and patients perspective, all aiming together to ‘Translate’ into betterment of Arthroscopy strategies and surgeries. Although the Journal will focus on Asian studies, it will be open to submissions from all across the globe.
The Journal will be open access, peer reviewed and will have three issues every year. It will be published in both online and print formats. The Journal is the official Arthroscopy Journal of the Orthopaedic Research Group. The Research Group has affiliation to Ebscohost and is a member of Crossref. Thus primarily the journal will be indexed with Ebscohost and will have a doi (digital object identifier) for each article. Within due course we aim to index the journal with all major indexes including Pubmed and Science citation index.

What is unique about AJA?
The most important unique point of AJA is that it is a Surgeon Initiated Journal. The entire concept of the journal, the designing of website, manuscript portal and guidelines are all made by a team of surgeons. The team will be self-publishing the Journal and there will be no external publisher involved. All the rights of the journal is with the editorial board and the core team of AJA and no rights belong to any external body. This gives us a lot of flexibility and helps the journal to adapt rapidly to changing needs of the readers and authors. The journal decisions can be taken rapidly and since the entire process is controlled by the AJA team, the quality of peer review and content will be excellent. With no constraint of a corporate publisher, we can lay down our own rules and regulations and provide best of services to the Arthroscopy community
We believe AJA is an ambitious project and has much potential to evolve along with the evolution of Arthroscopy Surgery. We have great plans for AJA and we hope for great co-operation from the Arthroscopy community. Please do send your suggestions, opinions and comments to us at the editorial email. AJA is a journal “By the Surgeon, for the Surgeon, and of the Surgeon” and together we can take it to great heights

Abstract

Bone patella tendon bone (BPTB) graft versus Hamstring (HT) Graft is still an issue that is debated. Both the graft have stood the test of time with high patient satisfaction however each have their own advantages and disadvantages. BPTB has advantages of good stability and bone to bone healing and disadvantage of anterior knee pain, numbness and quadriceps weakness. HT graft have advantage of less donor site morbidity, less extension deficit and disadvantage of having a slightly higher failure rate and hamstring weakness. Irrespective of these named advantages and disadvantages the patient reported outcomes are similar with both graft and difference in choice of graft is poorly understood. In this review we simply try to bring our reader up-to-date with the current literature on this controversy
Keywords: Bone patella tendon bone graft, hamstring graft, anterior cruciate ligament reconstruction.


Introduction

Anterior cruciate ligament (ACL) is required for static and dynamic stabiliser of the knee joint and purpose of ACL reconstruction is to stabilize and to resume function to maximum extent (1, 2). The ideal graft for use in anterior cruciate ligament reconstruction should have structural and biomechanical properties similar to those of the native ligament, permit secure fixation and rapid biologic incorporation, and limit donor site morbidity (3). Moreover, these properties should be present at the time of graft implantation and persist throughout the incorporation period too (3).
Graft options available are broadly grouped into autograft such as bone patellar bone tendon graft (BPTB), hamstring graft, Quadriceps graft and allograft such quadriceps, patellar, Achilles, hamstring, and anterior and posterior tibialis tendon graft (3-6). Allografts are useful to minimize donor site morbidity but are associated with increased cost, slower incorporation time, increased risk of disease transmission, and a higher failure rate (2). The synthetic grafts are yet to prove themselves and currently the most commonly used graft used for ACL reconstruction are autografts namely hamstring or BPTB graft. With BPTB graft comes with advantages of excellent initial fixation, biomechanical properties, durability, success at long- term follow-up with reduced pivot shift test (7, 8) and disadvantage of few reports suggesting donor site morbidity of patellofemoral osteoarthritis, scar formation with shortening of the patellar tendon, loss of terminal knee extension, and patellofemoral pain(2,9,10).
Semitendinosus and gracilis tendons (quadrupled hamstring tendon [HT]) have found to minimize donor site morbidity causing less anterior pain(8) with disadvantage of numbness of the anterior knee caused by injury to the infrapatellar branch of the saphenous nerve during graft harvest(2), longer rehabilitation period(3,10) and persisting pivot shift test at long term follow up(7). There are multiple extrinsic and intrinsic confounding variables(11) while studying the results of ACL reconstruction out of which isolated effects of a single extrinsic variable of graft choice is to be made.

Method of Review
There are several review articles published in literature including Pubmed, Medline and Cochrane database to compare of graft superiority (hamstring versus BPTB) in ACL reconstruction. We primarily did a pubmed search with Bone-Patellar Tendon-Bone Grafting as the Mesh major keyword. Two hundred and eighty five article were found and reviewed. There were 51 articles that either compared the two grafts or were meta-analysis of such articles. These 51 articles were then further reviewed to construct this review. There were 9 metanalysis among these 51 articles and 3 additional systematic reviews (1,4,7, 11-20). The Cochrane review of 2011 and a systematic summary of systematic reviews was also added to this list (21,22). Results of all these reviews were compiled and presented in Table 1. Other relevant articles were added to the review depending on the significance of their findings. It was noted that in most article the main areas of comparison between the two grafts were stability, donor site morbidity, complications, rehabilitation status, functional outcomes and revision rates due to graft. The present review is also arranged in this format.

Functional outcome
Functional outcome was measured in most of the articles using scores like Lysholm knee score, Tegner activity level, International Knee Documentation Committee (IKDC) scores etc. None of the studies found any difference in functional outcome measured (1,4,7,11-19,23-25) and hence both the grafts are equally effective in terms of restoring the functional ability of the patients. Pinczewski et al noted that Level 1 and 2 sports activities were significantly reduced from 73 to 85% (short term) to 45-57% (long term results) in both HT and BTPB groups (11). Recent review mentions that patients with HT graft are almost twice more likely to return to sports but patient with BPTB Graft are more likely to return or exceed the preoperative sports level (22). Other also indicate that patients with BPTB graft return to activity earlier than the HT graft (12). This may be probably because BPTB graft provide more static and rotational stability (1,15). Poolman et al (17) commented that modern techniques of HT graft will further increase stability and improve return to activity. However this is not confirmed by recent articles and possibly better controlled trials will be needed to eventually answer the question.

Donor site morbidity and complication after graft harvesting
When overall incidence of morbidity was reviewed, HT graft patient have lower incidence of morbidity (12,15). Anterior knee pain and kneeling pain was significant in BTPB group as compared with HT group(1–3,11,23). Anterior knee pain is related to the secondary chondromalacia patella which happens after ACL reconstruction regardless of graft type but it is noted that it can be five times greater in BPTB group versus HT group(2). There was a significant extension loss of >5 degrees in BPTB group versus HT group(1). It is noted that there was a concentric and eccentric reduction in Quadriceps power which was related to poor satisfaction rates (23). The Cochrane review in 2011 noted that BPTB Graft resulted in loss of knee extension range and strength while HT graft showed trend toward loss of flexion range and strength (21). There was a slight risk of patellar fracture which was mainly related to the errors in the surgical technique or use of unnecessary deeper saw cuts or osteotomes(23). Other donor site problems noted are patellar tendinitis, rupture of patellar tendon, increased joint stiffness, late chondromalacia and injury to infrapatellar branch of saphenous nerve(2,3,23). Reduced ultimate range of motion may be related to the rigid construct used in fixing BPTB graft (2). Other disadvantage of hamstring graft are injury to the superficial branch saphenous nerve and weakness of the hamstring muscles after operation (23, 24).

Stability
Stability has shown varied results in different studies and possible is a function of surgical technique and rehabilitation [Table 1].

Table 1: Comparative analysis of meta-analysis comparing BPTB and HT autograft

Table 1: Comparative analysis of meta-analysis comparing BPTB and HT autograft

Stability was assessed by Lachman test, pivot shift test and KT -1000 arthrometer in most series. Some authors reported no significant difference between either HT or BPTB group at long term follow up (11, 2). However, in mid-term follow up the side-to-side instrumented laxity (>2 mm) was greater in HT group as compared to BPTB group (7). BTPB is also found to be more rotationally stable with respect to pivot shift test (1).
Stability in case of HT graft was based on the number of strands used during surgery when compared with BPTB graft (1). When a 2 strand HT graft was used a statistical difference was noted in case of KT – 1000 and pivot shift test in favour of BPTB graft whereas Lachman test was not significant in both groups. If a 4 strand HT graft with a suspensory fixation like endobutton was used then the statistical difference was not significant in both the groups and had near normal Lachman, pivot shift tests and KT – 1000 testing(1,10,26–28). There is a slightly higher degrees of laxity noted in quadrupled hamstring graft as compared with BPTB graft especially in females in long term studies(2,20). Cochrane review noted that BPTB reconstructions are more likely to result in statically stable knees but they are also associated with more anterior knee problems. However there is insufficient evidence to predict superiority of one graft over other in long results in respect to functional outcome(21). In a study, comparing double bundle reconstruction with HT graft and anatomical BPTB graft positioning equal results are found with respect to stability and laxity throughout the range of motion(29). The recent summary of meta-analysis however concluded that BPTB graft are more stable as per the current available evidence (22)

Rehabilitation
It is noted that integration of bone to bone healing with direct insertion is much faster in BPTB graft as compared to bone to soft tissue healing by means of indirect insertions with sharpey’s fibres in case of HT graft(23). So with rapid incorporation with graft healing to bone, there is potential for accelerated rehabilitation in BPTB graft and may be earlier return to play sports activities(3,23). It usually takes 6 weeks for a BPTB to incorporate in the host bone whereas around 8 to 12 weeks with HT graft(3). Short term studies showed mixed results of quadriceps strength with HT graft harvest whereas long term studies shows no difference in quadriceps strength with BPTB versus HT graft(8,20). Evaluation of functional capacities: power, strength, velocity and dynamic stability of knee extensor and flexor muscles after ACL reconstruction showed that use of a BPTB autograft achieved better muscular and functional capacities than the HT autograft(6). During rehabilitation with hamstring graft requires less supervision with less risk of complications such as the infrapatellar contracture syndrome, arthrofibrosis or persisting pain(23).

Osteoarthritis Risk
Radiographic assessment showed no significant differences between the two groups in terms of osteoarthritic findings classified according to the Fairbank and Ahlback rating systems in short term studies(26) and mild osteoarthritic changes in BPTB group at mid and long term follow up as compared with HT group(11). Overall, osteoarthritis was identified in 16% (BPTB 19%; ST 13%.) according to the Ahlback rating system and 68% (BPTB 67%; ST 70%; ) according to the Fairbank rating system(26). Xie et al found the risk of development of OA was around 61% greater in BPTB graft as compared to HT Graft (14). Early osteoarthritic changes are also function of primary injury and associated injuries like meniscal injuries and cartilage injuries (30). However late onset osteoarthritis will require much longer follow up and none of the current studies offer much insight into development of OA in long term (22)

Failure rates
There is no obvious difference in the occurrence of ligament failure between HT group and the BPTB group after ACL reconstruction in long term studies but a few studies demonstrate reduced failure rates with BPTB graft(1). Hamstring graft harvest weakens the knee flexor strength leading to slightly higher degrees of graft failure (2,4). However, these studies had a selection bias which had included studies using double or triple strand graft which gave slightly higher failure rates. Long term studies have shown to have equal success rates with quadrupled hamstring graft or BPTB graft(8,20). Moreover, it is also noted that the fixation modality and anatomical placement of ACL is responsible for low failure rates(20) It has been noted that contralateral ACL tear with BPTB graft is statistically significant as compared to HT graft in short term studies whereas in long term studies there is no increase in contralateral ACL tear(8). A risk factor for contralateral ACL rupture was a return to sports that involved sidestepping, pivoting, and jumping (8). In a registry study based on 45,998 primary ACL Reconstructions in Scandinavi it was found that patients receiving patellar tendon autografts have a statistically significantly lower risk of revision compared with patients receiving hamstring autografts(5).


Conclusions

As per current reviews and evidence, both graft achieve good functional outcome in patients. BPTB graft may offer a more stable knee and possible achieve rapid and effective return to preinjury activity level. HT graft have less donor site morbidity and with new effective fixation modalities, they may also match the stability achieved by BPTB grafts. However there is insufficient evidence to clearly establish a winner and probably more robust future studies will be better able to define the role of each of these autograft options
