Management of the pathologic long-head biceps tendon remains controversial. Biceps tenotomy is a simple intervention but may result in visible deformity and subjective cramping. Comparatively, biceps tenodesis is technically challenging, and has increased operative times, and a more prolonged recovery. The purpose of this study was to determine the incidence of popeye deformity following biceps tenotomy versus tenodesis, identify predictors for developing a deformity, and compare subjective and objective outcomes between those that have one and those that do not. Data for this study were collected as part of a randomized clinical trial comparing tenodesis versus tenotomy in the treatment of lesions of the long head of biceps tendon. Patients 18 years of age or older with an arthroscopy confirmed biceps lesion were randomized to one of these two techniques. The primary outcome measure for this sub-study was the rate of a popeye deformity at 24-months post-operative as determined by an evaluator blinded to group allocation. Secondary outcomes were patient reported presence/absence of a popeye deformity, satisfaction with the appearance of their arm, as well as pain and cramping on a VAS. Isometric elbow flexion and supination strength were also measured. Interrater reliability (Cohen's kappa) was calculated between patient and evaluator on the presence of a deformity, and logistic regression was used to identify predictors of its occurrence. Linear regression was performed to identify if age, gender, or BMI were predictive of satisfaction in appearance if a deformity was present. Fifty-six participants were randomly assigned to each group of which 42 in the tenodesis group and 45 in the tenotomy group completed a 24-month follow-up. The incidence of popeye deformity was 9.5% (4/42) in the tenodesis group and 33% (15/45) in the tenotomy group (18 male, 1 female) with a relative risk of 3.5 (p=0.016). There was strong interrater agreement between evaluator and patient perceived deformity (kappa=0.636; p<0.001). Gender tended towards being a significant predictor of having a popeye with males having 6.6 greater odds (p=0.090). BMI also tended towards significance with lower BMI predictive of popeye deformity (OR 1.21; p=0.051). Age was not predictive (p=0.191). Mean (SD) satisfaction score regarding the appearance of their popeye deformity was 7.3 (2.6). Age was a significant predictor, with lower age associated with decreased satisfaction (F=14.951, adjusted r2=0.582, p=0.004), but there was no association with gender (p=0.083) or BMI (p=0.949). There were no differences in pain, cramping, or strength between those who had a popeye deformity and those who did not. The risk of developing a popeye deformity was 3.5 times higher after tenotomy compared to tenodesis. Male gender and lower BMI tended towards being predictive of having a deformity; however, those with a high BMI may have had popeye deformities that were not as visually apparent to an examiner as those with a lower BMI. Younger patients were significantly less satisfied with a deformity despite no difference in functional outcomes at 24 months. Thus, biceps tenodesis may be favored in younger patients with low BMI to mitigate the risk of an unsatisfactory popeye deformity

Adequate visual clarity is paramount to performing arthroscopic shoulder surgery safely, efficiently, and effectively. The addition of epinephrine in irrigation fluid, and the intravenous or local administration of tranexamic acid (TXA) have independently been reported to decrease bleeding thereby improving the surgeon's visualization during arthroscopic shoulder procedures. No study has compared the effect of systemic administered TXA, epinephrine added in the irrigation fluid or the combination of both TXA and epinephrine on visual clarity during shoulder arthroscopy with a placebo group. The purpose of this study is to determine if intravenous TXA is a safe alternative to epinephrine delivered by a pressure-controlled pump in improving arthroscopic shoulder visualization during arthroscopic procedures and whether using both TXA and epinephrine together has an additive effect in improving visualization. The design of the study was a double-blinded, randomized controlled trial with four 1:1:1:1 parallel groups conducted at one center. Patients aged ≥18 years undergoing arthroscopic shoulder procedures including rotator cuff repair, arthroscopic biceps tenotomy/tenodesis, distal clavicle excision, subacromial decompression and labral repair by five fellowship-trained upper extremity surgeons were randomized into one of four arms: Pressure pump-controlled regular saline irrigation fluid (control), epinephrine (1ml of 1:1000) mixed in irrigation fluid (EPI), 1g intravenous TXA (TXA), and epinephrine and TXA (EPI/TXA). Visualization was rated on a 4-point Likert scale every 15 minutes with 0 indicating ‘poor’ quality and 3 indicating ‘excellent’ quality. The primary outcome measure was the unweighted mean of these ratings. Secondary outcomes included mean arterial blood pressure (MAP), surgery duration, surgery complexity, and adverse events within the first postoperative week. One hundred and twenty-eight participants with a mean age (± SD) of 56 (± 11) years were randomized. Mean visualization quality for the control, TXA, EPI, and EPI/TXA groups were 2.1 (±0.40), 2.1 (±0.52), 2.6 (±0.37), 2.6 (±0.35), respectively. In a regression model with visual quality as the dependent variable, the presence/absence of EPI was the most significant predictor of visualization quality (R=0.525; p < 0 .001). TXA presence/absence had no effect, and there was no interaction between TXA and EPI. The addition of MAP and surgery duration strengthened the model (R=0.529; p < 0 .001). Increased MAP and surgery duration were both associated with decreased visualization quality. When surgery duration was controlled, surgery complexity was not a significant predictor of visualization quality. No adverse events were recorded in any of the groups. Intravenous administration of TXA is not an effective alternative to epinephrine in the irrigation fluid to improve visualization during routine arthroscopic shoulder surgeries although its application is safe. There is no additional improvement in visualization when TXA is used in combination with epinephrine beyond the effect of epinephrine alone

The functional importance of the long head of biceps tendon remains controversial, but it is well accepted as an important source of anterior shoulder pain. Both biceps tenotomy and tenodesis have well-documented results in the native shoulder. Management of the long head of biceps tendon during shoulder arthroplasty remains controversial. The existing literature supports surgical treatment of the biceps during shoulder arthroplasty. Walch et al. reported the largest series in multicenter study of over eight hundred shoulder arthroplasty patients with or without biceps tenodesis. The authors found more reproducible pain relief with biceps tenodesis and no difference in range of motion. Similarly, Soliman et al. reported on a prospective review of 37 patients undergoing hemiarthroplasty for fracture randomly assigned to biceps tenodesis vs. no treatment. The authors found a statistically significant improvement in Constant score and shoulder pain with biceps tenodesis. If left untreated during shoulder arthroplasty, the intact biceps tendon may be a source of anterior shoulder pain requiring revision surgery. Tuckman et al. reported excellent pain relief after biceps tenotomy or tenodesis for biceps-related pain after previous shoulder arthroplasty. The decision to perform a biceps tenotomy versus a tenodesis during shoulder arthroplasty also remains controversial. Tenotomy may increase the risk of cosmetic pop-eye deformity and muscle cramping or fatigue over tenodesis. Therefore, routine long head of biceps soft tissue tenodesis is recommended during shoulder arthroplasty as it safe, reproducible, cost-effective, associated with improved outcome scores, and minimises the risk of cosmetic deformity and pain associated with biceps tenotomy

Total shoulder arthroplasty is becoming increasingly common. A biceps tenodesis or tenotomy has become a routine part of the operation. There are several advantages to a tenodesis or tenotomy. First, the long head of the biceps tendon is routinely pathologic. One study has shown that there are differences in gene expression and mechanical properties in the long head of the biceps tendon in the setting of glenohumeral joint arthritis. Clinically, we often see inflammation, tearing, adhesions, or other pathology. Second, it is largely accepted that the long head of the biceps tendon has minimal function at the shoulder. The biceps muscle primarily functions at the elbow. Therefore, there is little downside to performing a tenodesis if there is a chance of it generating pain after surgery. Another major reason to perform a tenodesis or a tenotomy is that the technique of total shoulder arthroplasty requires a subscapularis takedown or lesser tuberosity osteotomy. The ligaments and tendon associated with the subscapularis contribute to the stability of the biceps tendon and after subscapularis takedown, it is unlikely that the tendon would remain reduced in the groove. In addition, it is part of a technique to incise and release the rotator interval, additionally creating scarring and/or instability associated with the biceps tendon. Given those reasons, this is a very common and reasonable routine part of the procedure of total shoulder arthroplasty

I never considered this to be a significant problem if it is noticed. (back to that later). Aaron Rosenberg's report seems to have agreed, but at the last members meeting of the Knee Society, Boston, September 2009, others had experience that contradicted my view. With their experience, ultimately the results were very substantially compromised. This video and presentation show you how to avoid a bad result, actually obtain a perfect result, if you or your student assistant, resident or fellow, bags the MCL. There are three important points. (1) One needs to recognise the occurrence. (2) The setting is usually varus and so direct end-to-end repair cannot be depended upon. (3) Use of a semitendinosis tenodesis, together with an imperfect, distracted direct repair works perfectly well!. (1) Recognition: The setting is usually varus, but I have had one case in which the chief resident, working with the fellow succeeded in getting the MCL in a valgus knee! In this usually tight varus setting the key feature is that at some point in the case, before component placement, one notices that the exposure is all of a sudden better! Now, the guilty resident or just a passive assisting resident/fellow will usually disagree. The extension space is not so obviously lax, but the flexion space is. Secondly, you do not feel an intact ligament in flexion. And, to prove it I have had to do a little more exposure of the superficial MCL to show the tear. There are at least three mechanisms. Most common is a saw cut. Next is possibly injury with the scalpel or cutting cautery during exposure, and last is damage essentially pre-operatively by a very sharp medial osteophyte which has thoroughly abraded the ligament. Laxity in full flexion is not necessarily obvious as the posterior capsular integrity helps hide the instability. Again, the really intact ligament is well felt, and in the situation of laceration, the tibia pulls forward more on the medial side, the medial flexion space opens, and what was usually a tight exposure gets suddenly better. (2) When varus is the setting, I have found it impossible or at least uncomfortable to depend upon direct repair. When the soft tissues are needing to be released or simply undergoing more stress than usual and a lot more than on the lateral side, I see it as unwise to expect or depend upon only a medial repair to hold. (3) The semitendinosis tenodesis has worked essentially perfectly in every one of my cases. These patients have had no post-operative instability and they have had better than average to extremely good ROM. A presumably key point is not to alter the patient's post-operative regimen! And, to avoid some passive alteration of PT, I advise specifically that the surgeon or those in his/her team do not mention the occurrence to the patient, the family or the PT! I put the whole story in the op-note, and weeks later I will specifically tell the patient what the staple in place is all about

Shoulder arthritis in the young adult is a deceptive title. The literature is filled with articles that separate outcomes based on an arbitrary age threshold and attempt to provide recommendations for management and even potential criteria for implanting one strategy over another using age as the primary determinant. However, under the age of 50, as few as one out of five patients will have arthritis that can be accurately classified as osteoarthritis. Other conditions such as post-traumatic arthritis, post-surgical arthritis including capsulorrhaphy arthropathy, and rheumatoid arthritis create a mosaic of pathologic bone and soft tissue changes in our younger patients that distort the conclusions regarding “shoulder arthritis” in the young adult. In addition, we are now seeing more patients with unique conditions that are still poorly understood, including arthritis of the pharmacologically performance-enhanced shoulder. Early arthritis in the young adult is often recognised at the time of arthroscopic surgery performed for other preoperative indications. Palliative treatment is the first option, which equals “debridement.” If the procedure fails to resolve the symptoms, and the symptoms can be localised to an intra-articular source, then additional treatment options may include a variety of cartilage restoration procedures that have been developed primarily for the knee and then subsequently used in the shoulder, including microfracture, and osteochondral grafting. The results of these treatments have been rarely reported with only case series and expert opinion to support their use. When arthritis is moderate or severe in young adults, non-arthroplasty interventions have included arthroscopic capsular release, debridement, acromioplasty, distal clavicle resection, microfracture, osteophyte debridement, axillary nerve neurolysis, and bicep tenotomy or tenodesis, or some combination of these techniques. Again, the literature is very limited, with most case series less than 5 years of follow-up. The results are typically acceptable for pain relief, some functional improvement, but not restoration to completely normal function from the patient's perspective. Attempts to resurface the arthritic joint have resulted in limited benefits over a short period of time in most studies. While a few remarkable procedures have provided reasonable outcomes, they are typically in the hands of the developer of the procedure and subsequently, other surgeons fail to achieve the same results. This has been the case with fascia lata grafting of the glenoid, dermal allografts, meniscal allografts, and even biologic resurfacing with large osteochondral grafts for osteoarthritis. Most surgical interventions that show high value in terms of improvement in quality of life require 10-year follow-up. It is unlikely that any of these arthroscopic procedures or resurfacing procedures will provide outcomes that would be valuable in terms of population healthcare; they are currently used on an individual basis to try to delay progression to arthroplasty, with surgeon bias based on personal experience, training, or expert opinion. Arthroplasty in the young adult remains controversial. Without question, study after study supports total shoulder arthroplasty over hemiarthroplasty once the decision has been made that joint replacement is the only remaining option

We know little regarding the long head of the biceps tendon's function but it is generally felt that it serves as a humeral head stabiliser by resisting superior migration during shoulder elevation. In total shoulder arthroplasty (TSA) the long head tendon is most commonly tenodesed as some have reported post-operative pain generated from an intact long head tendon. How does tenotomy or tenodesis of the long head tendon after TSA effect superior translation of the humeral head? We do not know the answer to this or if this increased tension causes any increase in subscapularis tendon failure. This will be presented as a possible reason to not remove the long head tendon of the biceps during TSA

The accessory navicular (AN) is a separate ossification center for the tuberosity of the navicular that is present in approximately 5–14% of the general population. It produces a firm prominence on the plantar-medial aspect of the midfoot. There may be a co-existent flexible flatfoot, but there is no conclusive evidence of a cause-and-effect relationship between the two conditions. It is usually not symptomatic, and few cases necessitate operative intervention. When symptoms require surgical treatment, excision of the AN, with or without advancement of the posterior tibial tendon, usually is considered. To describe new technique of AN excision and tibialis posterior tendon advancement (TPTA) using a bio-absorbable tenodesis screw and to investigate the outcome of this cohort in comparison to conventional simple excision. Retrospective 2 Cohort study. Single surgeon series from single institution. All patients younger than 18 years from Jan 2000 to Aug 2012 undergoing simple excision (SE) or excision with TPTA were identified from the prospectively collected database. Case notes were reviewed and data regarding demographics, indications for surgery, presence of Pes Planus, time from presentation to surgery, length of follow-up, patient satisfaction and complications were recorded. Pain and functional outcome were measured using Visual Analogue Score (VAS) and patient reported outcome measure- Oxford Ankle Foot Questionnaire- Child and Teenager Version. There were 6 patients in SE group. There were 3 males and 3 females. Mean age at surgery was 13.9 years. Surgical indication was painful swelling in all patients and in addition 1 had pes planus. There were 7 in SE & TPTA group. There were 3 males and 4 females. The mean age at surgery was 13.1 years. Surgical indication was painful swelling in all patients and in addition 1 had hind foot rigidity and 3 had pes planus. Postoperative protocol involved weight bearing with or without cast in SE group and non-weight bearing in cast for 6 weeks in TPA group. All patients reported excellent to good outcome. There were no complications and no reoperations after tendon advancement. In conclusion, based on our study findings, we think AN excision and TP advancement is a safe and effective technique for symptomatic pain relief. It is a novel technique which achieved excellent to good outcome in our series

Glenohumeral osteoarthritis (OA) is a challenging clinical problem in young patients. Given the possibility of early glenoid component loosening in this population with total shoulder arthroplasty (TSA), and subsequent need for early revision, alternative treatment options are often recommended to provide pain relief and improved range of motion. While nonoperative modalities including nonsteroidal anti-inflammatory medications and physical therapy focusing on rotator cuff strengthening and scapular stabilization may provide some symptomatic relief, young patients with glenohumeral OA often need surgery for improved outcomes. Joint preserving techniques, such as arthroscopic debridement with removal of loose bodies and capsular release, with or without biceps tenotomy or tenodesis, remains a viable nonarthroplasty option in these patients. Clinical studies evaluating the outcomes of arthroscopic debridement for glenohumeral OA in young patients have had favorable outcomes. Evidence suggests that earlier stages of glenohumeral OA have more favorable outcomes with arthroscopic debridement procedures, with worse outcomes being observed in patients with complete joint space loss and bipolar chondral lesions. More advanced arthroscopic options include inferior osteophyte excision and axillary neurolysis or microfracture of chondral lesions, both of which have demonstrated favorable early clinical outcomes. Patients with some preserved joint space and small osteophytes can avoid arthroplasty and have improved functional outcomes after arthroscopic debridement for glenohumeral OA. Caution should be advised when indicating this procedure for patients with large osteophytes, grade IV bipolar lesions, biconcave glenoids, and complete loss of joint space

Massive irreparable rotator cuff tears (MIRCTs) represent a difficult situation especially in painful and pseudoparalytic patients. A new technique, consisting of an arthroscopic implantation of an inflatable biodegradable “balloon”, serving as a temporary subacromial spacer, has been introduced recently for MIRCTs. The purpose of this paper is: 1) to present the efficacy and safety results of patients treated with the balloon; 2) to show that these results are maintained over time, after balloon degradation; 3) to compare these results to published results of other procedures available for MIRCTs. This paper presents the first group of 22 patients (females/males 13/8, one bilateral), treated in a single-surgeon, prospective and on-going series of 97 shoulders operated with the balloon, since September 2010. The mean age is 69.3 (52–86) and the average follow-up 52.5 months. The balloon is inserted arthroscopically and inflated with saline. The procedure is simple with a short operative time (10–20 min). It can also supplement partial repairs, especially of the subscapularis, as well as repairable massive tears with bad tissue quality. The balloon is not used in severe cuff tear arthropathy or complete insufficiency of the external rotators. Final outcome scores, Constant (CS) and UCLA scores are obtained at least three years after complete balloon degradation (which occurs within 12 months), and are also compared to those of other treatments available for MIRCTs. No device related safety issues were observed in this group. Good results, including rapid pain relief and restoration of active motion, which maintained over time, are obtained in 85% of the patients. The CS has improved significantly (average preop/postop: pain 2.9/12.7; ADL 6.8/17.4; ROM 22.8/36.6; strength 3.1/5.6; TOTAL 35.8/72.3; NORMATIVE 42.7/86.4). The UCLA score has also improved significantly (preop/postop: pain 1.9/8.6; function 3.9/8.6; active flexion 3.5/4.5; strength in flexion 2.4/3.4; satisfaction 0/4.5; TOTAL 11.2/29.8). Pseudoparalysis is reversed (average preop/postop flexion 86°/156.8°). The CS and UCLA score for the balloon are superior compared to published results of debridement, biceps tenotomy/tenodesis, partial repair, tuberoplasty and latissimus dorsi transfer. CS (86.4/63.8), CS pain (12.7/11.9) and flexion (156.8/128.0) are also better for the balloon compared to the reverse prosthesis. The balloon is indicated for MIRCTs, as well as reparable massive tears with a high risk of retear. The implantation is a straightforward and short procedure, which has excellent safety profile and positive effect on painful MIRCTs including pseudoparalysis. The balloon provides significant improvement in the CS and UCLA score that persists way beyond its degradation. The balloon patients' shoulder function is superior to the other available treatment options. Additional studies are needed to further confirm the effectiveness of the balloon as a first line treatment for MIRCTs

The management of scapho-lunate (SL) instability remains controversial. Since 2001, the senior author has used a modified Brunelli tenodesis to achieve soft tissue stabilization in patients presenting with dynamic or static SL instability. From 2001 to 2009, 13 patients were prospectively studied. All patients complained of painful clicking in the wrist, inability to use the wrist for loading activities, and all had a positive scaphoid shift test (Kirk Watson). Wrist arthroscopy was performed to confirm the diagnosis and to confirm the absence of degenerative change in all cases. Data collection pre-operatively included, range of motion, grip strength, DASH score and pain score. All patients had wrist immobilisation in a forearm cast for six weeks post operatively. Physiotherapy commenced at that stage and clinical assessment was performed at 3 months, six months and 12 months post surgery. Patients were discharged from follow-up after 12 months. A significant improvement in grip strength and DASH score was documented at the 12 month post operative assessment. The range of wrist flexion was decreased in all patients. The majority returned to their original employment. All patients reported that their wrist instability symptoms were improved. Conclusion. Scapho-lunate ligament reconstruction using a split flexor carpi radialis tendon graft to achieve soft tissue stabilization, provided satisfactory results in patients with chronic SL instability. Improvement in DASH score and grip strength were documented at one year follow-up

Objective. The aim of this study was to assess the results of combined arthroscopically assisted posterior cruciate ligament reconstruction and open reconstruction of the posterolateral corner in patients with chronic (3 months or more) symptomatic instability and pain. Patients & methods. A retrospective analysis of all the patients who had a combined reconstruction of the posterior cruciate ligament and the posterolateral corner between 1996 and 2003 was carried out. Nineteen patients who had the combined reconstruction were identified from the database. All the patients were assessed pre- and post-operatively by physical examination and three different ligament rating scores. All the patients also had weight bearing radiographs, MRI scans and an examination under anaesthesia and arthroscopy pre-operatively. The PCL reconstruction was performed using an arthroscopically assisted single anterolateral bundle technique and the posterolateral corner structures were reconstructed using an open Larson type of tenodesis. Results. Pre-operatively all the patients had a grade III posterior sag and demonstrated more than 20 degrees of external rotation as compared to the opposite normal knee on the Dial test. The average follow-up was 66.8 months (range 24 -108). Post-operatively 7 patients had no residual posterior sag, 11 patients had a grade I posterior sag and 1 patient had a grade II posterior sag. Five of the 19 patients demonstrated minimal residual posterolateral laxity. The Lysholm score improved from a mean of 41.2 to 76.5 (P=0.0001) and the Tegner score from a mean of 2.6 to 6.4 (p=0.0001). Conclusions. We conclude that while a combined reconstruction of chronic posterior cruciate ligament and posterolateral corner instability does not restore complete anatomical stability, improvement in symptoms and function demonstrate its value in these difficult injuries

The Rotator Cuff Registry is a unique initiative of the New Zealand Shoulder & Elbow Society. The aim of the study was to enrol nationwide all patients undergoing rotator cuff repair over a 22 month period to provide best practice guidelines for management of rotator cuff tears. To qualify for the Registry patients have to undergo surgical repair of either a partial or full thickness rotator cuff tear. Prior to surgery patients fill out a registration document as well as a pain score and Flex-SF function score. The Surgeon completes an operating day questionnaire detailing operative findings and repair methods. Follow-up is by pain and Flex-SF function scores returned at six, twelve and twenty-four months from surgery. By the 31st December 2010 3000 patients had been recruited. Analysis of the first 2684 patients for the purpose of this abstract showed 70% Male and 30% female. The dominant arm was involved in 65%. 19% of patients were in high demand occupations, 27% in medium demand and 33% low demand occupations. 16% of patients were treated with all arthroscopic repair, 40% were mini-open and 44% open. Comparing pre-op and one year post-op activity scores by surgical approach the Flex-SF improved by 12.97 points in the arthroscopic group, 13.3 in the mini-open and 12.72 in the open (NSS). Pre-op, 6 mth and 12mth pain scores were arthroscopic 4.60, 1.81 and 1.57, mini-open 4.34, 2.15 and 1.52 and open 4.82, 2.27 and 1.86. Preoperatively, the open approach had statistically more pain than the mini-open. At 6 months the arthroscopic group had statistically less pain than the open and at twelve months the mini-open had statistically less pain than the open group. For all tear sizes significant improvements in Fex-SF were seen both from preoperative levels to 6 month follow-up and from 6–12 month follow-up. A labral tear was present in 12% and repaired in 25% of these. No difference was seen in outcome between these groups Biceps tenolysis was undertaken in 27% and tenodesis in 23%. A single row repair was selected in 44% and a double row in 56%. Double row repair resulted in better Flex-SF scores in the large tears. Six, twelve and some twenty-four month data will be presented. Outcome was unaffected by the surgical approach with arthroscopic, mini-open and open results essentially identical

Over the last two decades, anatomic anterior cruciate ligament (ACL) reconstructions have gained popularity, while the use of extraarticular reconstructions has decreased. However, the biomechanical rationale behind the lateral extraarticular sling has not been adequately studied. By understanding its effect on knee stability, it may be possible to identify specific situations in which lateral extraarticular tenodesis may be advantageous. The primary objective of this study was to quantify the ability of a lateral extraarticular sling to restore native kinematics to the ACL deficient knee, with and without combined intraarticular anatomic ACL reconstruction. Additionally, we aimed to characterise the isometry of four possible femoral tunnel positions for the lateral extraarticular sling. Eight fresh frozen hip-to-toe cadavers were used in this study. Navigated Lachman and mechanised pivot shift examinations were performed on ACL itact and deficient knees. Three reconstruction strategies were evaluated: Single bundle anatomic intraarticular ACL reconstruction, Lateral extraarticular sling, Combined intraarticular ACL reconstruction and lateral extraarticular sling. After all stability tests were completed, we quantified the isometry of four possible femoral tunnel positions for the lateral extraarticular sling using the Surgetics navigation system. A single tibial tunnel position was identified and digitised over Gerdy's tubercle. Four possible graft positions were identified on the lateral femoral condyle: the top of the lateral collateral ligament (LCL); the top of the septum; the ideal tunnel position, as defined by the navigation system's own algorithm; and the actual tunnel position used during testing, described in the literature as the intersection of the linear projections of the LCL and the septum over the lateral femoral condyle. For each of the four tunnel positions, the knee was cycled from 0 to 90® of flexion and fiber length was recorded at 30® intervals, therefore quantiying the magnitude of anisometry for each tunnel position. Stability testing: Sectioning of the ACL resulted in an increase in Lachman (15mm, p = 0.01) and mechanised pivot shift examination (6.75mm, p = 0.04) in all specimens compared with the intact knee. Anatomic intraarticular ACL reconstruction restored the Lachman (6.7mm, p = 3.76) and pivot shift (−3.5mm, p = 0.85) to the intact state. With lateral extraarticular sling alone, there was a trend towards increased anterior translation with the Lachman test (9.2mm, p = 0.50). This reconstruction restored the pivot shift to the intact state. (1.25mm, p = 0.73). Combined intraarticular and extraarticular reconstruction restored the Lachman (6.2mm, p = 2.11) and pivot shift (−3.75mm, p = 0.41) to the intact state. There was no significant difference between intraarticular alone and combined intraarticular and extraarticular reconstruction. (p = 1.88). Isometry: The ideal tunnel position calculated by the navigation system was identified over the lateral femoral condyle, beneath the mid-portion of the LCL. The anisometry for the ideal tunnel position was significantly lower (5.9mm; SD = 1.8mm; P<0.05) than the anisometry of the actual graft position (14.9mm; SD = 4mm), the top of the LCL (13.9mm; SD = 4.3mm) and the top of the septum (12mm; SD = 2.4mm). In the isolated acute ACL deficient knee, the addition of a lateral extraarticular sling to anatomic intraarticular ACL reconstruction provides little biomechanical advantage and is not routinely recommended. Isolated lateral extraarticular sling does control the pivot shift, and may be an option in the revision setting or in the lower demand patient with functional instability. Additionally, the location of the femoral tunnel traditionally used results in a significantly more anisometric graft than the navigation's system mathematical ideal location. However, the location of this ideal tunnel placement lies beneath mid-portion of the fibers of the LCL, which would not be clinically feasible
