Incidence of peroneal tendon dislocation with talus fracture.

Traumatic peroneal tendon dislocation (PTD) is known to occur with pilon and calcaneus fractures, however, literature describing PTD in concurrence with injury to the talus remains limited. This was a retrospective review of adult patients with operatively treated talus fractures treated at a level I academic trauma center between 2007 and 2021. Charts, radiographs, and advanced imaging, when available, were reviewed for patient demographics, injury characteristics, and complications. 126 patients with 128 talus fractures were included. Incidence of PTD after talus fracture was 21.1 % (n = 27). Among isolated talus fractures only (n = 60), incidence of PTD was 16.7 % (n = 10). Peroneal rupture was separately found in 3 instances (2.3 %). PTD was significantly associated with lateral process fractures, making up one-third of total cases of PTD (p = 0.02), with 39 % of lateral process fractures demonstrating PTD. PTD was also associated with presence of fleck sign on injury radiographs (p < 0.00001). Among 27 cases of PTD, 14 (51.9 %) were diagnosed based on advanced imaging only (13 via CT scan and 1 by MRI), 4 (14.8 %) by operative report only, and 9 (33.3 %) based on both imaging and the operative report. Diagnosis was made acutely for 25 (89.3 %) PTDs, whereas 2 (7.4 %) were diagnosed in a delayed fashion. Three PTDs underwent delayed surgical intervention due to delayed diagnosis (n = 1), or missed dislocation by the surgeon although evident on injury scans (n = 2). Fractures with PTD developed higher rates of avascular necrosis (30.4 % versus 12.7 % among fractures without PTD, p = 0.044). PTD with talus fracture is relatively common and was identified in one out of five fractures within the studied cohort. Surgeons and radiologists should be cognizant of this injury, especially in the setting of a lateral process fracture and a positive fleck sign. III.

Trends in Rheumatoid Hand Surgery: Indications, Techniques, and Outcomes.

Rheumatoid arthritis (RA) causes persistent synovitis and arthritis, resulting in joint deformity and destruction throughout the body. As RA medications have evolved over the past 30 years, the surgical indications and techniques for RA joint deformities have changed. The aim of this review article is to summarize the recent trend of surgery for rheumatoid hand/finger deformities in previous reports and to present our recent surgical methods and outcomes for these deformities. A typical hand and finger deformity caused by RA is ulnar deviation, which is mainly caused by joint laxity and dislocation of the metacarpophalangeal joints, in addition to extensor tendon dislocation and/or wrist joint deformity. Although the incidence of hand/finger deformity and ulnar deviation caused by RA is decreasing due to advances in RA medications, patients with long-term RA or those with difficult-to-treat RA may still develop hand/finger deformity and ulnar deviation. If the hand/finger deformity is mild, it can be reduced manually, and conservative treatment with orthoses or splints may be required. If joint pain is severe despite good medical control of RA, or if the patient hopes to improve the appearance of the hand or fingers, surgical intervention is required. If there is only subluxation of the joints, which preserves their structure, reconstruction with only soft tissue surgery may be required. For example, for swan-neck deformity and boutonniére deformity, two of the most typical finger deformities due to RA, when the joint structures are almost intact and can be corrected manually, we opt for a surgical procedure that involves only soft tissue manipulation without the use of prosthetic implants. For ulnar deviation without joint destruction, we usually use a soft tissue-only surgical procedure. Our results have shown that the soft tissue-only surgery for ulnar deviation is as effective as joint replacement with implants. If the destruction of the joint has occurred and its dislocation/subluxation cannot be reduced manually, implant arthroplasty becomes necessary. If the joint destruction is severe, only intra-articular arthrodesis is required. In the era when RA can be controlled by medication, the hand surgeon should not overlook the change in the stage of the rheumatoid hand and should perform surgical intervention via the appropriate surgical method.

Lateral Wall Displacement of Calcaneal Fracture Leading to Peroneal Tendon Dislocation: Effect of the Distance of Lateral Wall Displacement on the incidence of Peroneal Tendon Dislocation.

Peroneal tendon dislocation accompanying an intra-articular calcaneal fracture is uncommon; however, such dislocations are often missed in the acute phase. Although risk factors have been reported, the correlation between the degree of lateral wall displacement of the fractured calcaneus and the incidence of peroneal tendon dislocation remains unclear. We retrospectively analyzed computed tomography scans of 61 patients who had calcaneal fractures to examine peroneal tendon dislocation and the association with degree of lateral wall displacement and presence of fleck signs, between peroneal tendon dislocation and non-dislocation cases. Peroneal tendon dislocation was observed in 11.5% (7/61) of the scan of patients with acute calcaneal fractures. The mean measurement of lateral wall displacement of the calcaneus was -3.3 (-11.1 to 8.9) mm. The fleck sign on radiographic images was evident in two cases (3.3%), whereas the fleck sign on scans was evident in three cases (4.9%). The mean measurement was significantly greater in cases with peroneal tendon dislocation than in those without dislocation (3.0 vs -4.1 mm, P<.05). The incidence of peroneal tendon dislocation and the lateral wall distance were significantly associated with the severity of calcaneal fractures, according to the Sanders classification system. The area under the curve generated for the medial deviation of the receiver operating characteristic curve was 0.976 and the cut-off value was 0.9. This study showed that lateral wall displacement is related to peroneal tendon dislocation and that the measurement of displacement using computed tomography scans can be a useful indicator of peroneal tendon dislocation.

Correction of non-traumatic extensor tendon dislocation and ulnar drift at the metacarpophalangeal joint by the modified Dell technique

BackgroundChronic ulnar extensor tendon dislocation at the metacarpophalangeal joint causes permanent extension deficit and ulnar drift. Several soft tissue procedures have been described for realignment of the extensor tendon in post-traumatic reducible instability or in combination with joint replacement in case of altered metacarpophalangeal joint in inflammatory conditions. However, no studies reported correction of both extension lag and ulnar deviation following isolated surgical treatment of ulnar extensor tendon dislocation at the metacarpophalangeal joint. The present study evaluated the clinical and functional results of isolated correction of chronic non-traumatic ulnar extensor tendon dislocation at metacarpophalangeal level using the modified Dell technique. HypothesisThe study hypothesis was that the modified Dell technique allows realignment of the extensor apparatus and correction of both metacarpophalangeal extension lag and ulnar drift. Patients and methods10 patients (24 fingers), operated on between June 2012 and May 2019, were evaluated at a mean follow-up of 36 months. The etiologies were rheumatoid arthritis in 17 cases, Jaccoud arthropathy due to systemic lupus erythematosus in 4, and degenerative in 3. A radial strip of distal-based extensor tendon, passed around the radial collateral ligament of the metacarpophalangeal joint downward from the surface, was sutured proximally to the remaining extensor tendon using the Pulvertaft technique. ResultsExtension deficit improved significantly, by a mean 26 ° (-9 ° postoperatively vs -35 ° preoperatively, p < 0.001). MP joint ulnar drift also improved significantly, by a mean 15 ° (6 ° vs 21 °, p < 0.001). Four fingers had preoperative swan neck deformity that improved postoperatively. There were 2 cases of recurrent dislocation. ConclusionThe modified Dell technique showed favorable results in treating chronic non-traumatic ulnar extensor tendon dislocation at metacarpophalangeal level in the long fingers, with realignment of the extensor system and correction of both metacarpophalangeal extension lag and ulnar drift.

Trimalleolar Fracture Associated with Subcutaneous Rupture of the Achilles Tendon and Traumatic Peroneal Dislocation: A Case Report and Review of the Literature.

We report the case of a 44-year-old man who sustained an Achilles tendon rupture with an associated trimalleolar fracture and traumatic peroneal dislocation of the left ankle after a snowboarding injury. These injuries have been surgically repaired; the patient has returned to all his activities 18 months after surgery. The possibility of such injuries occurring in combination should be considered. A thorough history, physical examination, and plain radiographs should be performed in higher energy trauma to the ankle. Additional diagnostic tests such as ultrasonography or magnetic resonance imaging may be used to supplement treatment. Level 5.

Peroneal Tendon Dislocation after Talus Fracture

Category: Trauma; Ankle Introduction/Purpose: Traumatic peroneal tendon dislocation (PTD) have been described in association with fractures of the pilon and calcaneus, however, the incidence of PTD after fractures of the talus has not been previously reported in the U.S. Methods: This was a retrospective review of adult patients with operatively treated fractures of the talus treated at a level I academic trauma center between 2007 and 2021. Charts, radiographs, and advanced imaging, when available, were reviewed for patient demographics, injury characteristics, and complications including diagnosis of peroneal tendon dislocation. Results: 126 patients with 128 talus fractures were included. Incidence of peroneal tendon dislocation was 21.1% (n=27). Peroneal rupture was found separately in 3 instances (2.3%). Among 27 cases of PTD, 14 (51.9%) were diagnosed based on advanced imaging, 7 (25.9%) by review of the operative report, and 6 (22.2%) based on both. 89.3% (n=25) of PTDs were diagnosed at time of injury, whereas 7.4% (n=2) were diagnosed several months after. Three PTDs underwent delayed surgical intervention due to delayed diagnosis (n=1), or missed dislocation by the surgeon, although evident on injury scans (n=2). Lateral process fractures had increased odds of PTD (OR 3.4, 95% CI: 1.3-8.9, p=0.012), as well as fractures with a positive fleck sign on radiographs (OR 14.3, 95% CI: 4.0-50.7, p=0.0001). Conclusion: Peroneal tendon dislocation with fracture of the talus is relatively common and was identified in one out of five fractures within the studied cohort. Surgeons and radiologists should be cognizant of this injury, especially in the setting of a lateral process fracture and a positive fleck sign.

Recurrent peroneal tendon dislocation-the current concept of management.

The peroneus muscles, consisting of the peroneus longus (PL) and peroneus brevis (PB) tendons, are vulnerable to injury at anatomically specific sites or within tendon sheaths. Peroneal tendon dislocation (PTD) is often misdiagnosed as a lateral ankle sprain as it occurs at a lower frequency than a lateral ankle sprain. Anatomical variations in the retromalleolar groove, soft tissue overstuffing, and presence of accessory peroneal muscles contribute to the etiology of PTD. PTD has been classified into four types based on injury patterns involving the superior peroneal retinaculum (SPR) and fibrocartilaginous ridge. Diagnosis involves recognizing tender points and using imaging including magnetic resonance imaging (MRI) and ultrasonography. Conservative treatments, including below-knee plaster casts, have varying success rates, and some patients progress to recurrent PTD (RPTD), prompting consideration of surgical interventions. Diagnosis is easy in patients with RPTD who can reproduce the dislocation by themselves; however, in many cases, this is not possible. In such cases, ultrasonography after intrasheath injection is effective in confirming the presence of a pseudo-pouch. RPTD can be diagnosed if a pseudo-pouch is identified during ultrasonography. Surgical approaches such as osteotomy, soft tissue procedures, and groove deepening techniques are used to stabilize the peroneal tendons. Soft tissue procedures, especially SPR reattachment, have emerged as a preferred option, demonstrating outcomes comparable to those of osteotomy, with fewer complications. Intrasheath subluxation, a unique PTD subtype, is diagnosed using ultrasonography. In this type of subluxation, no damage to the SPR is observed, and the positions of the PL and PB tendons are interchanged. Surgical intervention may involve excision of the synovium and SPR repair. In cases of PTD complicated by a longitudinal rupture of the PB tendon, suturing of the torn area or tubularization of the remaining tendon for partial resection of the degenerated tendon can be performed. The purpose of this article is to describe the methods for diagnoses and management of PTD.

The efficiency of total endoscopic surgery with preferential incision of the tendon sheath and traditional open surgery for the treatment of peroneal tendondislocation

Objective: To compare the outcomes between the patients of peroneal tendon dislocation treated by either total endoscopic surgery with preferential incision of the tendon sheath or traditional open surgery. Methods: This is a retrospective cohort study. The clinical data of 45 patients with peroneal tendon dislocation were operated on Department of Sports Medicine and Joint Surgery, Nanjing First Hospital from July 2016 to June 2020. There were 26 males and 19 females,aged (31.2±9.3) years (range: 17 to 45 years). Among them,23 patients underwent open peroneal tendon groove deepening followed by tendon sheath repair(traditional open group), and the other 22 patients underwent similar operations but all-endoscopically with preferential incision of peroneal tendon sheath(total endoscopic group). The perioperative data of patients were collected, and pain visual analogue score (VAS) was used to evaluate the pain changes before and after surgery and during the follow-up period, and the American Orthopaedic Foot and Ankle Society anklehindfoot scale (AOFAS-AH), range of motion (ROM), the MOS item short form health survey (SF)-36, and the homemade questionnaire of patient satisfaction were used to evaluate the patients' outcomes after the operation, and CT scan was carried out to observe the deepening of the fibular groove and MRI to observe the status of the peroneal tendon and sheath during the follow-up. Independent sample t test, Wilcoxon rank sum test and repeated measure ANOVA were used for comparison of quantitative data between groups. Chi-square test,Mann-whitney U or Fisher exact test was used for comparison of classified data, respectively;and paired sample t test was used for comparison of quantitative data before and after surgery in groups. Results: There was no statistically significant difference between the two groups of patients in terms of gender, age, disease duration, side of injury, and injury typing (all P>0.05). There was no significant difference between the two groups in terms of operation time((47.9±5.4)minutes vs. (47.2±6.3)minutes;t=0.402, P=0.690), but the incision length ((2.17±0.35)cm vs. 5.97±0.42)cm;t=32.892,P<0.01)and hospitalization time ((4.0±1.7)days vs. (7.6±3.6)days;t=4.249,P<0.01) were significantly shorter in the total endoscopic group than those in the traditional open group. All patients were followed up for more than 12 months, and the follow-up time was (19.2±3.9) months (range: 12 to 24 months). The total endoscopic group showed a significant increase in VAS, AOFAS scores, SF-36 scores and patient satisfaction rate at 3 months postoperatively and the last follow-up (all P<0.05). Three months after surgery, the ROM in the total endoscope group was higher than that in the traditional group ((62.14±1.46) ° vs. (53.13±1.52) °;t=20.315, P<0.01), and there was no significant difference between the two groups at the last follow-up ((63.18±1.10) ° vs. (63.48±2.43) °;t=0.531, P=0.599). Conclusion: Total endoscopic surgery with preferential incision of the tendon sheath has the advantages of minimally invasivenessas compared with traditional open surgery with faster recovery and better outcome.

Intermittent flexor hallucis longus dislocation: ultrasound findings.

We report a case of intermittent dislocation of the flexor hallucis longus at its passage in the retro-malleolar area, related to a post-traumatic detachment of the retrotalar pulley from the medial tubercle of the talus. High-resolution ultrasound depicted the anterior dislocation of the tendon during dynamic stress, by asking the patient to flex his hallux against the examiner resistance, with the ankle in slight dorsiflexion. The tendon normally relocated after the dynamic maneuver. Tendon dislocation was associated with a painful snap.

Fibular morphology is not associated with incidence of peroneal tendon dislocation.

The association of peroneal tendon dislocation with peroneal bone morphology and postoperative redislocation rates remains unknown. This study compared the fibula morphology in patients with peroneal tendon dislocation with that in a control population. The study enrolled 48 patients who underwent surgery for peroneal tendon dislocation at our institution during between 2018 and 2023. Thirty-five patients with preoperative magnetic resonance imaging of the ankle were defined as Group D and 35 with magnetic resonance imaging of the ankle for other reasons and with similar background data were selected as the control group (Group C). The posterior tilting angle of the fibula, posterolateral angle and posterolateral edge angle were evaluated at the plafond level. The posterior tilting angle, posterolateral angle and retromalleolar bone shape according to the Rosenberg classification (flat, convex, concave) were evaluated at the midpoint between the plafond and the tip. At the plafond level, the posterior tilting, posterolateral and posterolateral edge angles were 57.7 ± 11.1°, 123.8 ± 12.3° and 90.8 ± 13.7°, respectively, in Group D and 64.1 ± 15.4°, 121.1 ± 12.3° and 88.7 ± 12.2°, respectively, in Group C, with no significant differences. No significant between-group differences existed in the posterior tilting and posterolateral angles at the midpoint level. Moreover, no significant differences existed in distribution of the bone geometry according to the Rosenberg classification. There were no differences in morphology between patients with peroneal tendon dislocation and controls. This study provides useful information on the indications for primary surgery and whether bony approach is useful for peroneal tendon dislocation. Level IV.

Comparison of Clinical Efficacy between Arthroscopic and Open Surgery for Ogden Type 1-2 Peroneal Tendon Dislocation.

While the incidence of peroneal tendon dislocation (PTD) is relatively low, it is frequently underdiagnosed in clinical practice, and the misdiagnosis or improper treatment of this condition may lead to a decline in patients' quality of life. Currently, the surgical treatment options for PTD mainly include open and arthroscopic surgery. However, in order to evaluate the advantages and disadvantages of these two surgical approaches, further comparative research is needed. Therefore, the aim of this study is to investigate the early clinical outcomes of arthroscopic and open surgery in the treatment of Ogden type 1-2 PTD. We conducted a comprehensive analysis of 46 patients diagnosed with PTD who underwent surgery at our institution between January 2017 and January 2023. The patients were divided into two groups: the open surgery group, consisting of 26 cases, and the arthroscopic surgery group, consisting of 20 cases. To compare the effectiveness of the surgical approach, we evaluated several parameters, including the integrity of the superior peroneal retinaculum on MRI images, functional scores, pain interference scores, and ankle eversion muscle strength. These assessments are conducted respectively before the surgery, 1 month after the surgery, 3 months after the surgery, and at the final follow-up for each group of patients (at least 6 months post-surgery). Demographics and intergroup comparisons of the two groups of data were analyzed by t-test or the Mann-Whitney U test. Intragroup comparisons of the two groups of data were analyzed by one-way analysis of variance (ANOVA) or the Kruskal-Wallis test, followed by post hoc multiple comparisons. In the intragroup comparisons, both the arthroscopic surgery and the open surgery group demonstrated significant improvement in functional scores, pain interference scores, muscle strength, and MRI findings at the final follow-up postoperatively (p < 0.01). However, the open surgery group exhibited significant improvements in these outcomes at the final follow-up, while the arthroscopic surgery group showed significant improvement at 3 months postoperatively. In intergroup comparisons, the arthroscopic surgery group outperformed the open surgery group in functional scores, pain interference scores, and muscle strength 3 months after the surgery, with statistically significant differences (p < 0.01). Arthroscopic surgery offers advantages in early clinical outcomes, such as pain relief, function, and muscle strength improvement. However, over time, both approaches provide similar results regarding effectiveness.

Retromalleolar Groove Deepening in Recurrent Peroneal Tendon dislocation: Short- and Medium-Term Functional Outcomes

Recurrent peroneal tendon dislocation is a rare and often underrecognized condition. It may result from acute injuries, more commonly seen in athletes, or from untreated ankle sprains leading to chronic ankle instability. The aim of this study is to retrospectively evaluate short- and medium-term functional outcomes of the surgical technique involving deepening of the retromalleolar groove for the management of recurrent peroneal tendon dislocation. Nine patients, one of whom had bilateral dislocation, were enrolled in this study. The study group consisted of six males and three females, with a mean age of 31.2 years. CT scans were used to measure the depth of the neo-grooves, while the EFAS score (European Foot and Ankle Society Score) and AOFAS score (American Orthopedic Foot and Ankle Score) were used to assess functional results. The medium follow-up period was 4.8 years. CT scan data revealed a mean increase of 4.69 mm in the depth of the neo-retromalleolar groove. AOFAS scores improved from a mean preoperative value of 74.4 to 86.9 after surgery, and EFAS scores increased from a mean preoperative score of 19.7 to 31. Statistical analysis of clinical scores yielded significant results with a p-value &lt; 0.005. All patients returned to their previous sports activities within an average time of 7.7 months, reporting no pain or limitations. There were no recurrences observed. The retromalleolar groove deepening technique demonstrated excellent results in the treatment of recurrent peroneal tendon dislocation, evidenced by significant improvements in clinical scores, functional recovery, successful return to sports, and high patient satisfaction.

Peroneal Tendon Dislocation After Total Knee Arthroplasty in a Patient With Hereditary Multiple Exostoses

Case: We report a case of an 81-year-old woman with severe valgus deformity induced by hereditary multiple exostoses, which eventually led to the need for total knee arthroplasty (TKA) due to joint degeneration. Subsequently, she experienced peroneal tendon dislocation. Although changes in knee alignment can affect ankle joint alignment and reportedly lead to ankle pain after TKA, this is a rare case of nontraumatic peroneal tendon dislocation occurring after TKA. Conclusion: This case underscores the complexity of peroneal tendon dislocation after TKA where factors such as pre-existing anatomical abnormalities interact with the alignment changes induced by TKA.

Anatomical Features of Patients with Recurrent Dislocation of the Peroneal Tendons

Category: Hindfoot; Sports Introduction/Purpose: The occurrence of peroneal tendon dislocation (PTD) may be influenced by anatomical variations in the peroneal muscles and ankle lateral malleolus. One such factor is peroneal groove crowding, which can result from increased muscle and tendons bulk within the peroneal tendon sheath. Another potential factor is the shape of the retromalleolar groove, which determines the inherent stability of the tendons in the groove. This study aims to examine the anatomical variations of the retromalleolar groove and peroneal muscles in patients with and without recurrent PTD (RPTD) using magnetic resonance imaging (MRI) and computed tomography (CT). Methods: This study included 30 patients (30 ankles) with recurrent PTD who underwent both MRI and CT before surgery (PD group) and 30 age- and sex-matched patients (control (CN) group) who underwent MRI and CT. The imaging was reviewed at the level of the tibial plafond (TP level) and the center slice between the TP and the fibula tip (CS level). CT images were used to assess the appearance of a malleolar groove (convex, concave, or flat) and the posterior tilting angle of the fibula. MRI images were used to assess the appearance of accessory peroneal muscles, height of the peroneus brevis muscle belly, and volume of the peroneal muscle and tendons. Low-lying muscle belly (LLMB) of the PB was defined as when the musculotendinous junction extended beyond the tip. The Mann-Whitney U test was used to compare continuous variables, and Fisher’s exact test was used to compare nominal variables. Results: There were no differences in the appearance of the malleolar groove, posterior tilting angle of the fibula, or accessory peroneal muscles at the TP and CS levels between the PD and CN groups. However, the peroneal muscle ratio was significantly higher in the PD group than in the CN group at both levels (both p&lt; 0.001). The peroneal tendons ratio was not significantly different between the groups at both levels. The height of the peroneus brevis muscle belly was significantly lower in the PD group than in the CN group (p=0.001). LLMB of the PB was identified in 19 patients (63.3%) in the PD group and in eight patients (26.7%) in the CN group (p=0.009). Conclusion: The findings of this study suggest that LLMB of the PB and the peroneal muscle ratio are significantly related to RPTD, whereas retromalleolar bony morphology is not. Therefore, maintaining proper volume in the peroneal tunnel is more important than the groove shape. Reduction of the muscle belly of the peroneus brevis during RPTD surgery may help prevent peroneal tendon dislocation.

Snapping ankles: peroneal tendon subluxation and dislocation.

Peroneal tendon dislocation or subluxation is an orthopaedic condition that usually occurs as a result of injury to the superior peroneal retinaculum. The peroneal muscles are located in the lateral compartment of the leg, and their tendons run in the retromalleolar groove anchored by the superior peroneal retinaculum. Peroneal instability is usually classified using the Eckert and Davies classification, which was modified by Oden into a four-point grading system. The mechanism of injury is typically sudden forced dorsiflexion, resulting in aggressive tautness of the peroneal tendons, combined with a forced eversion of the hindfoot. Plain X-ray, ultrasound and magnetic resonance imaging are useful for imaging of the injury and in planning for surgery. Operative management has high success rates and there are multiple surgical techniques available, including superior peroneal retinaculum repair, tenoplasty, bone block procedures, groove deepening and endoscopic approaches, with little variation in outcome found between the approaches.

A Case Report and Technique Guide for Stabilization of Tibialis Posterior Tendon Dislocation in an Athlete

Acute dislocation of the posterior tibial tendon is an infrequent injury that is often missed. This injury is typically observed in young individuals in the course of sports. This is a case of an athlete who presented to our orthopedic clinic a week after injury to his ankle, following forceful eversion of the foot during a football game. Case reports have shown satisfactory results from surgical management, suggesting that this is the preferred treatment option. The report describes a simple and cost-effective technique for the retinaculum repair as well as adding to the small number of case reports on the description and treatment of tibialis posterior tendon dislocation.

Return to Sport after Surgical Treatment for Dislocation of the Peroneal Tendon: A Systematic Review of the Current Literature

Purpose: This study aims to analyze the return to normal activities and sports after surgical management of peroneal tendon dislocation through different surgical techniques. Methods: This review included studies (retrospective case series, prospective cohort study) that analyzed different aspects: return to sport (RTS), American Orthopedic Foot and Ankle Society Score (AOFAS), Visual Analogue Scale (VAS), satisfaction, and redislocation episodes after surgical treatment. We performed a systematic review, analyzing 1699 articles. We researched our selected studies through PubMed, Scopus, and Cochrane. The last search was performed in December 2022. We used the MINORS score to perform a quality assessment of pooled data. In total, 20 studies were included. Results: The postoperative AOFAS score, VAS scale, and high satisfaction percentages all improve with surgical therapy. At long-term follow-up, the redislocation following surgical treatment is minimal. Compared to patients who only receive superior peroneal retinaculum (SPR) repair and other surgical procedures, patients with groove deepening and SPR repair have greater rates of returning to sports (bony and rerouting procedures). Conclusions: Peroneal tendon dislocation surgery offers good outcomes, a quick return to sport, and high patient satisfaction. Those who received both groove deepening and SPR repair as opposed to other surgical procedures have greater rates of returning to sports.

Outcomes of Reverse Total Shoulder Arthroplasty with Latissimus Dorsi Tendon Transfer for External Rotation Deficit

Background: Latissimus dorsi transfer (LDT) has been purported to restore motion in patients undergoing reverse shoulder arthroplasty (RSA) who have preoperative combined loss of forward elevation (FE) and external rotation (ER). This systematic review summarizes the available evidence for the functional outcomes and complications after RSA with LDT. Furthermore, the effect of implant design and whether a concomitant teres major transfer (TMT) was performed were studied. Methods: A systematic review was performed per Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We queried PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases to identify articles reporting on LDT with RSA to restore ER. Our primary outcomes were ER, FE, Constant score, and complication incidence. Secondarily, we reported postoperative internal rotation (IR) and compared ER, FE, and Constant score based on lateralized versus medialized global implant design and whether concomitant TMT was performed. Results: Nineteen studies were evaluated; functional outcomes were assessed in 16 articles reporting on 258 RSAs (123 LDT, 135 LDT-TMT). Surgical indication was most commonly cuff tear arthropathy and massive irreparable cuff tear. Mean ER was −12° preoperatively and 25° postoperatively, FE was 72° preoperatively and 141° postoperatively. Mean postoperative Constant score was 65. Of 138 patients (8 studies) describing IR, only 25% reported a mean postoperative IR ≥L3. Subanalysis comparing lateralized versus medialized implants and whether TMT was concomitantly performed demonstrated no significant difference in postoperative ER, FE, and Constant score, nor preoperative to postoperative improvement in ER and FE. The complication rate was 14.1% (of 291 shoulders from 16 studies), including tear in the tendon transfer (n = 3), revision tendon repair (n = 1), nerve-related complication (n = 9), and dislocation (n = 9). Conclusions: RSA with LDT is a reliable option to restore motion, with a comparable complication rate with standard RSA. The use of medialized versus lateralized implants and whether the TM was concomitantly transferred may not influence clinical outcomes. Level of Evidence: Level IV. See Instructions for Authors for a complete description of levels of evidence.

Arthroscopic Onlay Biceps Tenodesis Utilizing 2 Knotless All-Suture Anchors

Background: Tenodesis is an effective surgical technique for the management of a pathologic long head of the biceps tendon. Tenodesis is performed with either an onlay (tendon opposed to cortical surface) or inlay (tendon docked into a reamed intra-cortical tunnel). Both techniques can be performed either from a subpectoral location, which is typically done through an open approach, or from a suprapectoral location, which is performed arthroscopically. The arthroscopic suprapectoral approach, when compared with its subpectoral counterpart, has been shown to report similar patient outcomes and complication rates. Indications: Arthroscopic suprapectoral biceps tenodesis is most commonly indicated in patients undergoing surgical treatment with anterior shoulder pain and biceps tendonitis, often associated with concomitant pathology. Less common indications include patients with superior labrum anterior and posterior tears as well as biceps tendon subluxation or dislocations. Patients with ruptured proximal biceps tendons are contraindicated, as the tendon is typically too distal for arthroscopic management. Technique Description: The biceps tendon is identified arthroscopically within the bicipital groove, just proximal to the pectoralis major tendon superior border. Suprapectoral tenodesis is then performed utilizing 2 knotless suture anchors for fixation. Results: Patient-reported outcomes following arthroscopic suprapectoral tenodesis in the literature have been found to be excellent with minimal complications. Despite current literature being inconclusive regarding the optimal site of fixation, the arthroscopic procedure minimizes the risk of infection, cosmetic deformity, and neurovascular injury that is seen in the open approach. In addition, the use of onlay fixation has traditionally avoided the risk of humeral fracture that is seen with inlay fixation. Discussion/Conclusion: This arthroscopic onlay suprapectoral tenodesis has the benefit of a time-efficient and easily reproducible technique that safely minimizes the risk of humeral fracture or neurovascular injuries. This technique historically has provided a strong fixation with excellent patient-reported outcomes.
