A biomechanical comparison between transosseous cruciate sutures and suture anchors for triceps tendon repair: a systematic review and meta-analysis

Background: The most common surgical option for acute triceps tendon tears is primary repair. There is no consensus as to which fixation construct is biomechanically superior. The purpose of this study was to evaluate the biomechanical properties of transosseous cruciate (TC) versus suture anchors (SA) for triceps tendon repair. Methods: A systematic review was performed by searching PubMed, the Cochrane library, and Embase using Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines to identify studies that analyzed the biomechanical properties of TC and SA techniques for triceps tendon repair. The search phrase implemented was “triceps tendon repair biomechanics.” Evaluated outcomes included medial displacement, lateral displacement, and ultimate load to failure. Results: Four studies met inclusion criteria, including 74 cadaveric specimens (TC: 37, SA: 37), for triceps tendon repair comparing a transosseous technique with TC to SA fixation. Pooled analysis from four studies reporting on medial and lateral displacement revealed a statistically significant difference between TC and SA (P=0.048 and 0.006). Pooled analysis from three studies reporting on ultimate load to failure revealed a statistically significant difference in favor of SA compared to TC (P=0.035). Conclusions: Biomechanical testing of SA for triceps tendon repair is associated with higher ultimate load to failure and lower medial and lateral displacement when under load following repair. The findings of this biomechanical meta-analyses should be considered along with clinical outcome data when surgeons make a decision regarding triceps tendon repair techniques.

Rotura Aguda do Tendão Tricípite Braquial no Atleta: Lesão Rara e por Vezes Esquecida

Brachial triceps tendon rupture accounts for less than 1% of all tendon tears in the upper limb. The authors present two cases of amateur athletes, males, one in crossfit and another in weightlifting. Both reported sudden pain in the posterior region of the elbow, when finishing the throw of the olympic bar. They were submitted to surgery and repair was performed with transosseous cruciate sutures complemented with anchorage, according to the technique described by James Paci. High clinical suspicion leads to early diagnosis and treatment. The surgical technique described allows for early rehabilitation with good long-term functional results.

Augmentation in the repair of traumatic patellar tendon ruptures. A novel mechanical and biological construct: Technical note

Patellar tendon ruptures are infrequent and potentially disabling injuries. These injuries are usually repaired with transosseous suture tunnels. However, this technique can produce a significant gap formation and prolonged postoperative immobilization. Although several techniques have been described to improve the integrity of the repair, the surgical technique of choice is a matter of debate especially when there is tissue loss due to high-energy trauma. This study aims to evaluate the clinical outcomes of patients with acute patellar tendon ruptures due to high-energy trauma treated with a novel construct configuration that includes a suture anchor and a figure-of-eight augmentation with hamstring autograft with medial and lateral reinforcement. To determine the clinical outcomes the International Knee Documentation Committee (IKDC) score was obtained pre-surgery and at 12 months of follow-up. A total of six patients were recruited, with a median age of 27.5 years, five of these were male. Three lesions were in the proximal pole of the tendon, two were mid-substance and one was in the junction with tibial tuberosity. The IKDC clinical score significantly increased from pre-surgery to the 12-month follow-up with a median difference of 32.8 (95% CI, 19.5–42.6, p = 0.0313). Likewise, the patients presented a post-surgery quadriceps strength level with a median of 5/5. All patients had full active knee extension with a median of 0–120°. There was no statistical difference in the range of motion comparing the surgical knee to the contralateral knee (p = 0.6883). No patient presented any type of reintervention or complication during the follow-up period. The configuration of the construct presented in the technique had not been reported before in the literature and combines the advantages of the use of suture anchors and biological augmentation with lateral and medial reinforcement. This technique may be useful in patients with traumatic injuries with and without loss of tissue. Although it is a small series with concomitant injuries, satisfactory clinical results were presented during follow-up.

Styloid Ulna Window Approach for Repair of Avulsed Foveal Attachment of Triangular Fibrocartilage Complex

To describe a surgical approach for open repair of the triangular fibrocartilage complex foveal avulsion via ulnar styloid osteotomy, and to assess its clinical results. We reviewed 12 patients with distal radioulnar joint (DRUJ) instability due to isolated foveal avulsion of DRUJ ligaments. Wrist arthroscopy was conducted for all patients to exclude the presence of concomitant tear of the superficial part of the triangular fibrocartilage complex and to corroborate the diagnosis with a positive hook test. Through an ulnar approach between flexor and extensor carpi ulnaris, an ulnar styloid osteotomy was performed under image intensifier control just ulnar to the fovea of the head of the ulna. The avulsed foveal attachment was anchored through transosseous sutures passing from the fovea to the neck of the ulna. The ulnar styloid was fixed by means of screws or tension band wires. Outcome measures included clinical assessment of pain (visual analog scale), grip strength, DRUJ instability, range of motion of the wrist, and modified Mayo wrist score. Radiographic assessment was done to determine union of the ulnar styloid osteotomy, DRUJ subluxation, and any hardware-related problems. Outcome measures were evaluated after a mean follow-up of 21 months. Healing of the osteotomy was obtained in all cases by 11 weeks. The DRUJ laxity, visual analog scale, and modified Mayo wrist score improved, while grip strength and range of motion remained unchanged. One patient had prominent hardware necessitating removal after union of the osteotomy. There were no reported cases of injury or neuropraxia of the dorsal cutaneous branch of the ulnar nerve. Open repair of an avulsed foveal attachment of the triangular fibrocartilage complex using an ulnar styloid osteotomy is an alternative to either open or arthroscopic repair approaches.

Two Intramedullary and 1 Extramedullary Cortical Button, With or Without Interference Screw, Show Biomechanical Properties Superior to Native Tendon in Repair of the Distal Biceps Tendon: A Systematic Review and Network Meta-analysis of Biomechanical Performance

The aim of this study was to use a systematic review and network meta-analysis (NMA) to compare the failure strength, maximum strength, stiffness, and displacement of available constructs for distal biceps repair. An NMA was conducted to determine the performance of 2 all-suture suture anchors (2x ASA), 2 intramedullary cortical buttons (2x IM CB), 2 suture anchors (2x SA), extramedullary cortical buttons (EM CB), extramedullary cortical button plus interference screw (EM CB+IFS), interference screw (IFS), single intramedullary cortical button (IM CB), single suture anchor (SA), trans-osseous suture (TOS), tension slide technique (TST), and tension slide technique plus suture tape (TST+ST). Analysis consisted of arm-based network meta-analysis under Bayesian random-effects model with Markov Chain Monte Carlo (MCMC) sampling. Biomechanical outcomes were summarized as treatment effects and their corresponding 95% confidence intervals (CI). Rank probabilities were calculated and used to generate each treatment's surface under the cumulative ranking (SUCRA) curve. Biomechanical properties were compared to native tendon. Displacement >10mm was defined as clinical failure. Twenty-one studies were included. For failure strength, no construct outperformed the native tendon but 2x SA, IFS, SA, and TOS demonstrated poorer failure strength. For the maximum load to failure, EM CB+IFS outperformed the native tendon. Compared to native tendon, EM CB+IFS, EM CB, and 2xIM CB were stiffer, while 2x SA and IFS were less stiff. No construct demonstrated >10 mm of displacement, but constructs with displacement above the mean (3.5 mm) included 2x ASA, 2xIM CB, and TOS. The fixation constructs that consistently demonstrated comparable or better biomechanical properties (failure strength, maximum strength, stiffness) to native tendon in distal biceps tendon repair were the extramedullary cortical button with or without interference screw and two intramedullary cortical buttons. No construct demonstrated displacement beyond standard definitions for clinical failure. This network meta-analysis of biomechanical studies suggest that extramedullary cortical button and two intramedullary cortical buttons may be the most stable construct for distal biceps repair fixation, with equivalent or better biomechanical properties compared to native tendon.

Anterior Malleolar Fractures: Pathoanatomy, Classification and Treatment Options

Category: Trauma; Ankle Introduction/Purpose: The anterior distal tibial tubercle (Tillaux-Chaput tubercle) frequently fractures in the wake of malleolar fractures. It provides attachment to the anterior tibiofibular syndesmosis and may be considered a fourth or anterior malleolus (AM). In analogy to posterior malleolar fractures, AM fractures may extend into the tibial incisura and tibial plafond. We analyzed the pathoanatomy of AM fractures and associated injuries in ankle fractures in adults. Methods: Over a course of 9 years, 140 patients (average age 58.3 years) with 140 acute malleolar fractures (OTA/AO 44) involving the anterolateral distal tibial rim were analyzed with CT imaging. All components of the malleolar fractures were analyzed and classified. Fracture patterns were compared with those of all 1,379 patients treated for malleolar fractures at our institution during the same 9-year period. Patients with fractures of the tibial pilon (OTA/AO 43) and patients aged less than 18 years were excluded as the frequent anterolateral distal tibial fractures along the physeal growth plate in adolescents are beyond the scope of this analysis. Fractures were classified according to the most frequent patterns and possible treatment options. Results: Of the 140 AM fractures, 52.9% were classified type 1 (extra-articular avulsion), 35.7% type 2 (incisura and plafond involvement), and 11.4% type 3 (impaction of the anterolateral plafond). The fibula was fractured in 87.1%, the medial malleolus in 67.1%, and the posterior malleolus in 69.3%. Isolated AM fractures were seen in only 6 cases (4.3%). The severity of AM fractures correlated negatively with that of posterior malleolar fractures (p<0.001). The proportion of pronation-abduction fractures increased and the proportion of supination external rotation fractures decreased with increasing severity of AM fractures (p=0.055). Fractures involving the AM had a prevalence of 12.6% of all ankle fractures and occurred significantly more frequently in pronation-type injuries (p<0.001). No supination-abduction fractures were seen with AM involvement. The interclass correlation coefficient for the proposed classification of AM fractures was 0.961 (95% CI 0.933-0.980) for interobserver agreement and 0.941 (95% CI 0.867-0.974) for intraobserver agreement. Conclusion: Knowledge of the 3D pathoanatomy of AM fractures and associated injuries may help with surgical planning. CT imaging should be employed generously in the assessment of complex ankle fractures, particularly with pronation injuries. In analogy to posterior malleolar fractures, fixation of displaced AM fractures potentially restores syndesmotic stability, congruity of the tibial incisura thus facilitating fibular reduction and joint congruity at the anterolateral tibial plafond. Proposed treatment options include transosseous suture for syndesmotic avulsions (type 1), screw fixation for fractures involving the incisura and plafond (type 2), and elevation of the impacted plafond with buttress plating for type 3 fractures.

The incidence of hip dislocation after posterior approach primary total hip arthroplasty: comparison of two different posterior repair techniques.

Total hip arthroplasty (THA) remains one of the most successful orthopedic surgical procedures. The posterior approach is associated with a higher incidence of post-operative dislocations than others. Adequate posterior soft tissue repair techniques, including capsulorrhaphy and transosseous bone sutures in the greater trochanter effectively reduce the dislocation rate. Post-operative "posterior hip precautions" were historically believed to reduce dislocation risks, although not clearly proven. The first protocol consists of capsulorrhaphy with the prescription of post-operative posterior hip precautions (TT) and the second, transosseous bone sutures without precautions (TB). This study aims to determine the optimal protocol to decrease the dislocation rate following posterior approach primary THA. A 10-year retrospective case-control chart review analyzed demographic, pre-, intra-, and post-surgical parameters. Primary outcomes were the difference in dislocation and revision surgery rates between protocols. Secondary outcomes included the incidence of recurrent dislocations and the identification of predictors of dislocation. 2,242 THAs were reviewed and 26 (1.2%) resulted in dislocation. Increased age (p = 0.04) ASA score (p = 0.03) and larger acetabular cup size (p < 0.001) were associated with heightened risk. Tendon to tendon (TT) repair saw a 1.62% dislocation rate versus 0.98% for tendon-to-bone (TB) repair, although statistically insignificant (p = 0.2). Transosseous repair resulted in recurrent dislocations for 8/16 (50%) patients compared to 6/10 (60%) in the suture group (p ≤ 0.001). No significance was found for prescription of posterior hip precautions. To our knowledge, this is the first study to perform a direct comparison of TT repair with posterior precautions to TB repair without posterior precautions. Similarity in dislocation rate, decreased recurrent events and the alleviated patient burden from precautions leads the authors to recommend the TB repair without precautions for a successful THA.

Surgical treatment of distal triceps tendon ruptures

Restoration of the anatomy and the original length of the muscle-tendon unit in triceps tendon ruptures. Acute and chronic triceps tendon ruptures with persisting symptoms and significant strength deficits. Infections and tumors in the surgical area. Prone position. Skin incision over the distal triceps in alateral direction around the olecranon. Mobilization of the tendon and débridement of the olecranon. Drilling of 2 × 2.9 mm suture anchor holes medial and lateral into the footprint of the olecranon. In addition, drilling through the olecranon 12 mm distal to the tip of the olecranon and transosseous introduction of 4sutures. Then the suture anchors (all-suture or titanium anchors) are inserted into the drill holes. Refix the deep and superficial tendons with the anchor threads. Refix the upper tendon portions with the transosseous sutures. In the case of chronic lesions, agraft interposition is necessary. Dorsal 10 ° splint, then change to an orthosis fixed in 20 ° extension and passive mobility 0-30 ° flexion for 6weeks. From the 7th week onwards, load-free, physiotherapeutically controlled increasing mobilization. Starting weight-loading from the 13th week on. Full load after 6months. In all, 34male strength athletes with acute triceps tendon rupture underwent surgery using the hybrid technique described and were prospectively recorded. The MEPS‑G score averaged 94.7points, there were no permanent limitations in mobility, and the postoperative strength ability averaged 94% of the original strength performance ability. The return to sport achieved 100%. The complication rate was 20.6%. Reconstruction of the distal triceps tendon using hybrid technology leads to very good functional results. Half of all patients complained of symptoms even before the rupture, which suggests previous damage to the distal triceps tendon caused by degeneration.

Clinical Outcomes of Arthroscopic One-Tunnel Triangular Fibrocartilage Complex Transosseous Suture Repair Are Not Diminished in Cases of Ulnar Styloid Process Fracture Nonunion

To determine whether clinical outcomes of arthroscopic one-tunnel wrist triangular fibrocartilage complex (TFCC) transosseous suture repair are not diminished in cases of ulnar styloid process fracture nonunion (USPFN). Patients who underwent arthroscopic 1-tunnel transosseous suture repair of Palmer 1B foveal TFCC tear (with/without superficial fiber tear; Atzei class 2 or 3 TFCC tear) from 2015 to 2020 were retrospectively reviewed. Group I was the TFCC foveal tear repair group with USPFN. Group II was the TFCC foveal tear repair group without USPFN. In group I, no additional treatment for USPFN was made. Functional preoperative and postoperative outcomes were compared by Modified Mayo Wrist Score (MMWS); Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH) score; grip strength; pain visual analog scale (VAS); and distal radioulnar joint (DRUJ) stability. Wrist posteroanterior, lateral, and both oblique views of the wrist were used to assess the ulnar styloid process before and after operation. This study consisted of 66 patients: group I (n= 22) and group II (n= 44). No differences were found between the 2 groups preoperatively in MMWS, Quick-DASH, grip strength, and VAS (MMWS: P= .94, Quick-DASH: P= .23, grip strength: P=.69, VAS: P= .45). No differences were found between the 2 groups with respect to outcome measures postoperatively in MMWS, Quick-DASH, grip strength, and VAS (MMWS: P= .59, Quick DASH: P= .82, grip strength: P= .15, VAS: P= .84). All of the enrolled patients achieved restored function with negative ballottement test and maintained DRUJ stability on follow-up. Of the 22 USPFN cases in group I, 11 (50%) showed spontaneous union after transosseous TFCC foveal repair without any additional USPFN treatment. The proportion of patients achieving a minimal clinically important difference for the Quick-DASH was similar between the 2 groups. Although this current study has insufficient statistical power, the available data suggest that patients with TFCC foveal tear combined with USPFNs treated with arthroscopic transosseous repair surgery could experience similar functional improvement compared with those with TFCC foveal tear without USPFNs. The presence of USPFN accompanied by Palmer 1B type TFCC foveal tear may not affect the clinical results, including MMWS, Quick-DASH, grip strength, VAS, and DRUJ stability of patients who undergo arthroscopic 1-tunnel transosseous suture repair. Level III, retrospective comparative study.

Surgical Treatment of the Proximal Humeral Fracture with Transosseous Sutures Technique

Surgical Treatment of the Proximal Humeral Fracture with Transosseous Sutures Technique

Tissue-engineered tendon nano-constructs for repair of chronic rotator cuff tears in large animal models.

Chronic rotator cuff tears (RCTs) are one of the most common injuries of shoulder pain. Despite the recent advances in surgical techniques and improved clinical outcomes of arthroscopically repaired rotator cuffs (RCs), complete functional recovery-without retear-of the RC tendon through tendon-to-bone interface (TBI) regeneration remains a key clinical goal to be achieved. Inspired by the highly organized nanostructured extracellular matrix in RC tendon tissue, we propose herein a tissue-engineered tendon nano-construct (TNC) for RC tendon regeneration. When compared with two currently used strategies (i.e., transosseous sutures and stem cell injections), our nano-construct facilitated more significant healing of all parts of the TBI (i.e., tendon, fibrocartilages, and bone) in both rabbit and pig RCT models owing to its enhancements in cell proliferation and differentiation, protein expression, and growth factor secretion. Overall, our findings demonstrate the high potential of this transplantable tendon nano-construct for clinical repair of chronic RCTs.

A new suture fixation technique for the Akin Osteotomy of the Proximal Phalanx: You don’t need any implant

BackgroundVarious fixation methods have been described for Akin osteotomy, based on using metal implants or transosseous sutures. The aim of this study was to evaluate radiological outcomes and complications of closing wedge Akin osteotomy based on a crossed suture configuration of the joint capsule rather than using implants. The null hypothesis is that a crossed suture has comparable radiological results to other techniques, with no additional complications. MethodsIt’s a retrospective study. Patients who underwent Akin osteotomy fixed either with implant or joint capsule suture between 2015 and 2018 were included. Distal articular set angle corrections in pre- and postoperative anteroposterior foot x-rays were calculated by 2 observers. Complications, such as pain, infection, non-union and need of surgery revision, was compared at 1 year follow-up. Results89 patients, 30 in the implant group and 59 in the suture group. Mean distal articular set angle corrections were 6.43 (SD 5.54) and 7.36 (SD 5.48) degrees in the implant and suture groups, respectively, without statistically significant differences (p 0.454). Complications were 2 local pain and 1 wound infection cases in the suture and implant groups, respectively (p 0.138, p 0.197). ConclusionAkin osteotomy with suture fixation yields comparable radiological results to metal implant fixation methods without increasing the associated complications.

Nonabsorbable Transosseous Sutures for Lower Pole Patella Fractures

Background: Treatment alternatives for patella fractures with the inferior pole are still being deliberated. In addition to tension-band wiring, metal implant-related complications are also not uncommon to occur in patellar fracture treatment. It is common to encounter implant-related complications such as implants failing, palpable hardware which require supplementary techniques to resolve. We evaluated participants with inferior poles of patella fracture treated with transosseous nonabsorbable sutures on functional outcomes. Methodology: This study encompasses observation of patients having transosseous suture fixation by no. 5 Ethibond for fixation of distal pole patella fractures. This was a longitudinal study piloted at a tertiary care center between January 2020 and June 2022. Patients' functional outcomes were assessed using the Bostman score. Results: The Bostman scoring system was used to evaluate the outcome at the final follow-up. In 19 patients, 7 (36.84%) patients showed outstanding and 11 (57.89%) patients showed good outcomes at the termination of 9 months follow-up. Only one patient established an unsatisfactory result. Conclusion: Distal pole patella fractures can be effectively fixed via transosseous suturing with unabsorbable sutures. Fast recovery and minimal implant-related complications are possible with this procedure. The resurgery rate is also significantly reduced.

Poster 186: Repair of the Distal Biceps Tendon: A Systematic Review &amp; Network Meta-Analysis of Biomechanical Performance

Objectives:Rupture of the distal biceps is common and demonstrates excellent short- and long-term clinical outcomes following surgical repair. Prior studies have individually evaluated the biomechanical construct strength of multiple fixation devices, but none has comprehensively evaluated constructs in a head-to-head comparison. We sought to compare the failure strength, maximum strength, stiffness and displacement of available constructs for distal biceps repair.Methods:A network meta-analysis was conducted to determine the relative performance of 2 all-suture suture anchors, 2 intramedullary cortical buttons, 2 suture anchors, extramedullary cortical buttons, extramedullary cortical button plus interference screw, interference screw, single intramedullary cortical button, single suture anchor, trans-osseous suture, tension slide technique and tension slide technique plus suture tape. Analysis consisted of arm-based network meta-analysis under Bayesian random-effects model with Markov Chain Monte Carlo (MCMC) sampling. Geometry of the network was represented visually via a network plot with nodes representing treatments and edges representing direct comparative evidence. Biomechanical outcomes of fixation techniques were summarized as treatment effects and their corresponding 95% confidence intervals (CI). Rank probabilities were calculated and used to generate each treatment’s surface under the cumulative ranking (SUCRA) curve.Results:A total of 21 studies were included in the network meta-analysis. For failure strength, the two intramedullary cortical buttons ranked highest (92.73%). For maximum strength, the extramedullary cortical button alone (86.96%) and extramedullary button plus interference screw (83.40%) ranked highest. The two intramedullary cortical buttons ranked highest in stiffness (98.75%), followed by the extramedullary cortical button with interference screw (88.75%) and extramedullary cortical button (75.00%). Finally, with respect to demonstrating the least displacement after loading, the two suture anchors (89.43%) ranked highest, followed by tension slide technique with suture tape (73.14%) and extramedullary cortical button (72.71%).Conclusions:The fixation constructs that demonstrated the greatest overall biomechanical performance in distal biceps tendon repair were the extramedullary cortical button and two intramedullary cortical buttons. Two suture anchors demonstrated the least displacement after loading.Figure 1.Cochrane risk of bias summary of included studies.Figure 2.Evidence networks for outcomes of failure strength (A), maximum strength (B), stiffness (C), and displacement (D).

Transosseous tunnels versus suture anchors for the repair of acute quadriceps and patellar tendon ruptures: A systematic review and meta-analysis of biomechanical studies

BackgroundMultiple techniques have been developed for the repair of acute quadriceps and patellar tendon ruptures with the goal of optimizing clinical outcomes while minimizing complications and costs. The purpose of this study was to evaluate the biomechanical properties of transosseous tunnels and suture anchors for the repair of quadriceps and patellar tendon ruptures. MethodsA systematic review of the PubMed and Embase databases was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using specific search terms and eligibility criteria. Meta-analysis was performed by fixed-effects models for studies of low heterogeneity (I2 <25%) and random-effects models for studies of moderate to high heterogeneity (I2 ≥25%). ResultsA total of 392 studies were identified from the initial literature search with 7 studies meeting the eligibility criteria for quadriceps tendon repair and 8 studies meeting the eligibility criteria for patellar tendon repair. Based on the random-effects model for total gap formation and load to failure for quadriceps tendon repair, the mean difference was 8.88 mm (95% CI, −8.31 mm to 26.06 mm; p = 0.31) in favor of a larger gap with transosseous tunnels and −117.25N (95%CI, −242.73N to 8.23N; p = 0.07) in favor of a larger load to failure with suture anchors. A similar analysis for patellar tendon repair demonstrated a mean difference of 2.86 mm (95% CI, 1.08 mm to 4.64 mm; p = 0.002) in favor of a larger gap with transosseous tunnels and −56.34N (95% CI, −226.75 to 114.07N; p = 0.52) in favor of a larger load to failure with suture anchor repair. ConclusionsTransosseous tunnels are biomechanically similar to suture anchors for quadriceps tendon repair. Patellar tendon repair may benefit from reduced gap formation after cycling with suture anchor repair, but the load to failure for both techniques is biomechanically similar. Additional studies are necessary to evaluate these and alternative repair techniques. Level of evidenceSystematic review and meta-analysis of biomechanical studies, Level V.

Elbow lateral ulnar collateral ligament reconstruction by transposition of the local extensor fascia septum: surgical technique and preliminary results

The lateral ulnar collateral ligament (LUCL) is a primary lateral stabilizer of the elbow that originates from the isometric center of the capitulum and inserts into the supinator crest of the ulna. LUCL injury may be due to trauma, chronic strain, or iatrogenic lesion. In patients with symptomatic LUCL insufficiency and recurrent posterolateral rotatory instability, surgical reconstruction can restore elbow stability. In primary acute treatment, the injured LUCL is reattached to the lateral epicondyle with transosseous sutures and anchors placed at the isometric origin of the ligament. If the ligament quality is poor, patients with chronic elbow instability may require reconstruction with a tendon autograft or allograft. Alternatively, the LUCL can be reconstructed by transposition of the local extensor fascia septum, a local flap that exploits the common extensor fascia connected to a thin strip of extensor digitorum quinti or the extensor digitorum communis intermuscular septum. We describe a new LUCL reconstruction technique based on the transposition of the local extensor fascia septum and report the preliminary result in a series of patients aged 50 years or less.

Radial Sided Triangular Fibrocartilage Complex Tears: A Comprehensive Review.

When evaluating the available literature on the diagnosis and management of triangular fibrocartilage complex tears (TFCC), ulnar tears comprise the major focus of TFCC literature. Radial-sided (Class 1D) tears are seldom researched or discussed. The purpose of this study was to review the methods for identifying and treating radial-sided TFCC lesions, by examining the anatomy of the TFCC, the pathology of its radial portion, diagnostic techniques, and both surgical and nonoperative treatments. The avascular nature of the radial TFCC may influence its healing potential. Magnetic resonance arthrogram is the gold standard for non-invasively diagnosing a radial-sided tear. Non-operative management should be exhausted prior to surgical intervention, which commonly involves an inside-out repair involving radial trans-osseous sutures. Still, the literature is limited by patient sample size and therefore requires a greater population of class 1-D tears to confirm optimal diagnostic and treatment methods.

Clinical Outcomes of the Arthroscopic Transosseous Suture Repair of the Rotator Cuff Using Absorbable Thread for the Medial Mattress Suture

We performed arthroscopic transosseous suture repair of the rotator cuff (ATOS) using absorbable threads for the medial mattress suture to prevent re-tear of the cuff at the medial mattress suture. This study aimed to evaluate the clinical outcomes of this procedure.

Arthroscopic-Assisted Foveal Reattachment of Triangular Fibrocartilage Complex Tears With Distal Radioulnar Joint Instability: A Comparison of Suture Anchors and Transosseous Sutures

To compare the clinical outcomes of arthroscopically-assisted suture anchor repair and transosseous sutures for repair of foveal triangular fibrocartilage complex tears in patients with distal radioulnar joint (DRUJ) instability. Sixty patients with triangular fibrocartilage complex foveal detachment associated with DRUJ instability were prospectively recruited and randomized into 2 equal groups-the anchor repair group and the transosseous repair group. The primary outcome was DRUJ function after 2 years, which was assessed by the DRUJ evaluating system. The secondary outcomes were grip strength, visual analog scale for pain, Mayo Modified Wrist ScorePatient-Rated Wrist Evaluation score, and the Disabilities of the Arm, Shoulder, and Hand score. There were no significant differences between the groups for any of the outcome measures. Good-to-excellent outcomes (according to the DRUJ evaluation system) were achieved in 27 (90%) patients in the anchor repair group and 26 (86.7%) patients in the transosseous repair group. Fewer complications were observed in the anchor repair group. Both techniques yielded good and comparable outcomes with a lesser incidence of early complications in the anchor repair group.

Acute anterolateral knee instability in adults: combined proximal ACL and ALL injury repair is not inferior to standard ACL reconstruction with LET in 2 years.

Objectives:The objective was to compare the clinical results of ACL and ALL repair with those of standard ACL reconstruction + LET. The hypothesis was that combined repair is non-inferior to standard reconstruction + LET in adults with acute anterolateral knee instability.Methods:Patients with severe acute anterolateral instability (ACL + ALL injuries) who underwent early ACL surgery (injury-to-surgery interval < 14 days), a total of 58 patients, were prospectively enrolled in the study. ACL injuries were classified according to the Sherman classification. Patients with a proximal injury (types 1 and 2) were assigned to receive ACL repair (ACLrep) (n = 37), patients with types 3 and 4 and moderate tissue quality (n = 21) were assigned to receive ACL reconstruction (ACLrec) + lateral extra-articular tenodesis (LET). Repair consisted of transosseous suture of the stump to the anatomic origin of the ACL and direct repair of the ALL. Reconstruction consisted of standard ACL reconstruction by semitendinosus-gracilis (STG) autograft + LET. PROMs included IKDC, Lysholm, KOOS, and assessment of anteroposterior (AP) knee laxity in 2 years.Results:A sample size calculation showed that 21 patients in each group were needed for a 95% power (with a 95% CI) to show non-inferiority of the repair group considering an arthrometric side-to-side difference of at least +1.5. Patients in the ACLrep group showed better results on all scales: mean IKDC was 95.51 ± 52.4 versus 86.92 ± 13.92 (p = 0.02); mean KOOS was 97.49 ± 2.71 versus 93.50 ± 7.05 (p = 0.009); and mean Lysholm was 96.98 ± 5.14 versus 91.69 ± 10.08 (p = 0.02). There was no difference in the KT1000 measurement (ACLrep: 1.70 ± 1.02; ACLrec: 2.21 ± 0.80; p = 0.11). The one-sided 95% CI was 1.7 (to 2.02) (< at the 3.01 limit for non-inferiority) for ACLrep and 2.21 (to 2.46) for ACLrec, p = 0.147. Therefore, non-inferiority was provenConclusion:In acute knee instability resulting from a combined ACL and ALL injury, direct repair is non-inferior in terms of PROM and knee laxity compared to standard ACL + LET reconstruction in 2 years.
