Superficial Medial Collateral Ligament Reattachment During High Tibial Osteotomy: Regulate Tension, Preserve Stability!

ABSTRACT: High tibial osteotomy (HTO) is a commonly performed surgical procedure. Although it is well-known that the superficial medial collateral ligament (sMCL) should be released during HTO, there is still no agreement on performing its reattachment. Considering the function of the sMCL, after its release during HTO, increased medial joint instability may be expected. We present a technique for sMCL reattachment that prevents medial gapping development and maintains nearly native pressure on the medial compartment of the knee joint by matching the tension on the sMCL to the size of the osteotomy gap. This technique is suitable for any correction angle.

Percutaneous Superficial Medial Collateral Ligament Release Outcomes During Medial Meniscal Arthroscopy: A Systematic Review.

Project description:Purpose:To systematically review the literature to better understand the technique, outcomes, and complications after percutaneous superficial medial collateral ligament (sMCL) lengthening during knee arthroscopy to address isolated medial meniscal pathology. Methods:A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines using a PRISMA checklist. The inclusion criteria consisted of English-language articles or articles with English-language translations documenting the use of percutaneous sMCL lengthening during arthroscopic knee surgery to treat isolated meniscal pathology (repair vs meniscectomy) with reported postoperative outcomes and complications. Results:Four studies met the inclusion criteria, consisting of a total of 192 patients undergoing percutaneous sMCL lengthening. No perioperative complications related to iatrogenic chondral damage, fracture, or additional meniscal injury were reported. Mild postoperative pain at the medial needle tract site lasting up to 15 days after surgery was reported in 52% of patients (46 of 88). At final follow-up, laxity on valgus stress testing showed a range from 0 to 1.1 mm with a range from -0.3° to 0.9° of radiographic medial joint space widening compared with preoperative radiographs. The length of follow-up ranged from 1.5 to 24 months. Conclusions:The percutaneous "pie-crusting" technique remains the most commonly reported technique to lengthen the sMCL during arthroscopic meniscal surgery. Percutaneous lengthening represents a safe and effective method of increasing medial joint space visualization, with no reported perioperative or postoperative complications and with minimal, likely clinically insignificant residual joint laxity after surgery on valgus stress testing at final follow-up compared with preoperative values. Level of Evidence:Level IV, systematic review of Level IV studies.

Superficial and Deep Medial Collateral Ligament Reconstruction for Chronic Medial Instability of the Knee.

Project description:There are several surgical techniques for medial collateral ligament reconstruction, including anatomic or nonanatomic medial knee reconstruction. Although the medial collateral ligament consists of the superficial medial collateral ligament (sMCL) and deep medial collateral ligament (dMCL), surgical procedures have only been described for reconstruction of the sMCL alone or reconstruction of the sMCL and posterior oblique ligament. The dMCL assists the knee in rotational stability, primarily in extension, moving into early flexion. We describe sMCL and dMCL reconstruction with semitendinosus and gracilis autografts using adjustable-length loop suspensory fixation devices for tibial fixation. By use of our technique, it is possible to provide good stability and satisfactory results for medial instability of the knee.

Combined Posterior Cruciate Ligament and Superficial Medial Collateral Ligament Knee Reconstruction: Avoiding Tunnel Convergence.

Project description:Combined posterior cruciate ligament (PCL) and medial collateral ligament (MCL) injuries represent a complex pathology that requires a thorough clinical and radiographic examination to diagnose and identify all injured structures. Anatomic reconstruction of the injured ligaments is recommended, including double-bundle PCL reconstruction and superficial MCL augmentation. In the setting of this complex reconstruction, several technical aspects require consideration and preoperative planning, including the risk of femoral tunnel convergence on the medial aspect of the femoral condyle. This article details our technique for combined anatomic double-bundle PCL reconstruction and superficial MCL augmentation to avoid tunnel convergence. Level I (knee); level II (PCL).

Technique for Arthroscopically Assisted Superficial and Deep Medial Collateral Ligament-Meniscotibial Ligament Repair With Internal Brace Augmentation.

Project description:Deep medial collateral ligament (MCL) injury leads to meniscal lift-off and extrusion of the medial meniscus, resulting in instability and increased medial compartment pressures with subsequent cartilage damage. Repair of the deep MCL meniscotibial ligament in concert with superficial MCL repair or reconstruction is intended to restore the native anatomy , stability, and function of the medial meniscus. We present an arthroscopically assisted technique using standard arthroscopy portals and a medial open approach.

Medial Opening Wedge Proximal Tibial Osteotomy.

Project description:Genu varus malalignment can lead to medial compartment overload and progression of ipsilateral compartment osteoarthritis. To slow this process, a medial opening wedge proximal tibial osteotomy (PTO) can be performed. This type of PTO is indicated in patients with genu varus malalignment and isolated medial compartment osteoarthritis of the knee, prior to or concurrent with medial compartment cartilage procedures or meniscal transplants, chronic posterolateral corner deficiency, or chronic anterior cruciate ligament deficiency. When treating ligamentous instability, a PTO can be performed in isolation, with simultaneous ligament reconstruction, or as a staged procedure with the osteotomy first, followed by ligament reconstruction if instability persists. Failure to address malalignment in cases of concurrent ligament reconstruction leads to increased stress on the graft and potential graft failure. One distinct advantage of this procedure is the ability to correct deformities in the sagittal and coronal planes. The purpose of this article was to describe our technique used to perform a medial opening wedge PTO.

Patellofemoral Joint Reconstruction for Patellar Instability: Medial Patellofemoral Ligament Reconstruction, Trochleoplasty, and Tibial Tubercle Osteotomy.

Project description:Recurrent patellar instability can be very debilitating and may require surgical intervention. A thorough workup must be completed in this subset of patients. Risk factors for recurrent instability include patella alta, trochlear dysplasia, an increased tibial tubercle-trochlear groove distance, and insufficiencies in the medial retinacular structures. Necessary treatment of these risk factors, once identified, should be addressed surgically. Patellofemoral reconstruction must be individually tailored to each patient's anatomy and may necessitate medial patellofemoral ligament reconstruction, tibial tubercle osteotomy, or trochleoplasty in any combination or as a standalone procedure. This article details our technique for surgical treatment of recurrent patellar instability with a medial patellofemoral ligament reconstruction, an open trochleoplasty, and a tibial tubercle osteotomy for patients with severe trochlear dysplasia, an increased tibial tubercle-trochlear groove distance, or patella alta.

Combined Anterior Cruciate Ligament, Medial Collateral Ligament, and Posterior Oblique Ligament Reconstruction Through Single Tibial Tunnel Using Hamstring Tendon Autografts.

Project description:Combined anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries are the most common type of combined ligamentous injury of the knee. The optimal treatment for these combined injuries is controversial. Combined ACL and MCL-posterior oblique ligament (POL) reconstruction avoids late anteromedial rotatory instability and chronic valgus instability of the knee and decreases the increased stress on the ACL graft. Graft choice (hamstring tendon autograft, quadriceps bone-patellar tendon-bone autograft, or Achilles tendon allograft) and anatomic restoration of the medial and posteromedial corner of the knee are challenges of this combined reconstruction. This article describes a technique that allows combined ACL and MCL-POL reconstruction. The hamstring tendons from the contralateral limb are tripled and used as the ACL graft. The gracilis tendon from the ipsilateral limb is doubled and used as the MCL-POL graft. The semitendinosus tendon of the ipsilateral limb is preserved. After ACL reconstruction, the MCL-POL graft is suspended on the ACL graft at the distal end of the tibial tunnel and the graft limbs are used for open reconstruction of the MCL and POL. Three interference screws (Arthrex, Naples, FL) and 1 metal staple are used for graft fixation of this combined reconstruction.

Combined tibial plateau levelling osteotomy and tibial tuberosity transposition for treatment of cranial cruciate ligament insufficiency with concomitant medial patellar luxation.

Project description:ObjectivesTo describe the surgical technique and report short-term outcome for combined tibial plateau levelling osteotomy and tibial tuberosity transposition (TPLO-TTT) as an option in the treatment of cranial cruciate ligament insufficiency with concomitant medial patellar luxation.MethodsMedical records were reviewed (2011-2013) of dogs that underwent a standard tibial plateau levelling osteotomy followed by a tibial tuberosity transposition in the frontal plane and stabilized with pin and tension-band wire fixation as a component of surgical treatment for combined cranial cruciate ligament insufficiency and medial patellar luxation. Signalment, fixation method together with any ancillary procedures, function at the in-hospital follow-up examinations, and any complications were recorded. Healing was assessed retrospectively based on the grading criteria of the International Society Of Limb Salvage.ResultsFifteen stifle joints in 11 dogs were identified; 13 stifles were available for in-hospital follow-up. All 13 achieved union (3 with grade III/IV and 10 with grade IV/IV radiographic healing scores); mean time to healing was 10.6 (± 2.9) weeks. Patellar ligament thickening was also identified radiographically in seven of the 13 of stifle joints. All dogs were reported to have mild or no lameness at their last follow-up examination. No catastrophic or major postoperative complications occurred that required additional surgery. Patellar re-luxation did not occur in any of the 13 stifles available for in-hospital follow-up.Clinical significanceThe TPLO-TTT was found to be a reliable and effective technique when used as a part of the treatment of combined cranial cruciate ligament insufficiency with concomitant medial patellar luxation in this series of dogs.

A Technique of Superficial Medial Collateral Ligament Reconstruction Using an Adjustable-Loop Suspensory Fixation Device.

Project description:This report describes superficial medial collateral ligament reconstruction of the knee using a novel method of graft fixation with the ACL Tightrope RT (Arthrex, Naples, FL). After tibial fixation with either a standard interference screw or staple, femoral fixation of the semitendinosus tendon is performed with the adjustable-loop suspensory fixation device, which allows for both initial graft tensioning and re-tensioning after cyclical knee range of motion. This provides the ability for the graft to accommodate for resultant soft-tissue creep and stress relaxation, thereby allowing for optimal soft-tissue tension and reduction in laxity at the end of the procedure.
