PurposeTo compare the pullout strength of a bio-inductive implant (BI) used to augment medial patellofemoral ligament (MPFL) repair with semitendinosus graft in biomechanical cadaveric model.MethodsSix matched pairs cadavers (12 knees) were testing comparing tendon (Semi-T) versus BI. The Semi-T was harvested from 1 pairs. A standard double-bundle technique using 2 sockets upper two-thirds patella 15 mm apart performed. After docking into patella, dissected free soft tissues and potted...

Introduction: The purpose of this study is to prospectively evaluate differences in post-arthroscopic partial meniscectomy patients based upon the use a small-bore needle arthroscope or traditional for intraoperative visualization. Materials and Methods: Sixty-eight were randomized 1:1 fashion have visualization arthroscopic performed with either arthroscope. Prior surgery one-week post procedure, underwent peak torque isometric knee extension testing using handheld dynamometer Visual Analog...

Introduction: Healthcare institutions have sought to standardize opioid prescribing after elective total joint arthroplasty. The purpose of this study was (1) compare prescriptions at discharge with perceived patterns and (2) determine the relationship between preoperative adjunctive treatments opioids prescribed discharge. Methods: All surgeons who performed arthroplasty shoulder, hip, or knee from January 1, 2021, October 4, 2023, a single academic institution were included. Surgeons...

Surgical treatment of partial-thickness rotator cuff tears remains challenging and controversial, with several traditional options including debridement acromioplasty, transtendon or in situ repair, take-down repair. A resorbable bioinductive bovine collagen implant has shown promise as an alternative option for tears.Data from a registry were analyzed to further establish that the contributes improved patient-reported outcome (PRO) scores across large number patients treated tears.Case...

Surgical knee arthroscopy is among the most commonly performed procedures in United States. The decision to treat often based on clinical examination and magnetic resonance imaging. Equivocal results frequently require patients undergo surgical arthroscopy, exposing patient inherent risks potential complications. Office-based needle provides an alternative approach visualizing intra-articular anatomy pathology real time. purpose of this article provide a standardized diagnostic knee.

Classically, arthroscopy has been considered one of the diagnostic gold standards for assessing intra-articular knee and shoulder abnormality.To assess risks associated with in-office needle arthroscopy.Case series; Level evidence, 4.A retrospective case series analysis was performed by evaluating consecutive arthroscopies 13 physicians at independent institutions. The findings both major minor complications were reported each surgeons based on office documentation. data analyzed as a lump...

In this paper, we design, develop, and validate a surgical robotic system, entitled Robossis, to assist long-bone fracture reduction, i.e., alignment, surgeries. Unlike traditional surgeries, Robossis enables the surgeon precisely align fractured bone in presence of large traction forces torques. The proposed system includes novel 3-armed robot, bone-gripping mechanism, master controller. 6-DOF wide-open parallel robot has unique architecture, which facilitates positioning inside providing...

The purpose of this study was to prospectively collect safety and efficacy data in a large group patients undergoing arthroscopic repair full-thickness rotator cuff tears augmented with resorbable bioinductive bovine collagen implant designed promote healing.Seventeen centers across the United States enrolled an institutional review board-approved registry outcomes on implant. Patients surgical management were enrolled. Inclusion criteria age ≥21 years, willingness participate ability read...

The medial collateral ligament (MCL) is the most commonly injured of knee; however, only a minority cases require surgical intervention. Classically, isolated grade I and II MCL injuries are treated nonoperatively whereas III may be with surgery. High-grade frequently associated concomitant knee ligamentous injuries, particularly anterior cruciate ligament. Nonetheless, repair or reconstruction generally reserved for patients persistent valgus instability after failed nonoperative...

The use of biologics and rotator cuff augmentation have seen significant growth in interest to combat complications retear after arthroscopic repair. Bio-inductive implants are used induce new tissue formation; however, they lack structural strength at the time implantation. Conversely, dermal allografts provide implantation, but do not allow for sufficient incorporation carry inherent risks allograft tissue. BioBrace™ (Biorez, New Haven, CT) is a bio-inductive scaffold composed highly...

To evaluate the relationship between patient resilience and patient-reported outcome measures (PROMS) after primary anterior cruciate ligament (ACL) reconstruction.Patients who underwent an ACL reconstruction by a single surgeon January 2012 June 2020 were identified institutional query using Current Procedural Terminology codes. Patients included if they (1) (2) had minimum of 2 years' follow-up. Data retrospectively collected regarding demographics, surgical details, visual analog scale...

Distal biceps tendon ruptures are uncommon injuries that have a re-rupture rate of 1.2% - 6%. In severe traumatic or chronic injuries, distal repair may require augmentation due to insufficient tissue quality. Unsuccessful treatment these can result in the loss approximately 40% supination strength and 30% elbow flexion strength. There has been growing interest biologic orthopedic surgery, its incorporation into repairs increased as well. Established bio-inductive implants dermal allografts...

This letter presents Robossis, a surgical robotic system for automated femur fracture alignment. Robossis is the integration of an optical tracking with 6-degree-of-freedom (6-DOF) 3-armed parallel robot that satisfies clinical and mechanical design requirements alignment surgery. In real-time, obtains spatial position distal proximal parts fractured femur. Then, auto-alignment algorithm uses this data to guide automatically accurately align bone fragments while overcoming muscle payload...

Femur fractures are prevalent in the general population and require complex surgical intervention. A significant amount of time effort is spent restoring alignment femur fractures, which called reduction step. This particular step would benefit greatly from a robot-assisted mechanism, where majority increased stress operating room occurs. To address this issue, we propose Wide-Open 3-armed parallel robot, entitled Robossis, that facilitates fracture reduction. Robossis system aims to improve...

Rotator cuff repair (RCR) is one of the most common arthroscopic orthopedic procedures performed worldwide. A high number clinical and subclinical re-tears exist post procedure, particularly in subset group large (>3cm) to massive tears revision (Agrawal 2012; Galatz et al. 2004; Djurasovic 2001; Burkhart 2007). Advances RCR over past two decades have nearly eliminated failures related implant failure. Currently mechanism failure lies suture “pull through” at suture-tendon interface...
