BACKGROUND: Many total knee arthroplasty (TKA) systems allow for so-called midlevel constraint (MLC) articular bearings that can be used with primary implants. The purpose of this study is to report the early outcomes with MLC bearings in primary TKA. MATERIALS/METHODS: From December 2005 to June 2015, minimum 2-year follow-up was available on 96 patients (103 TKA) who underwent primary TKA with an MLC bearing using the Vanguard Total Knee System. Outcomes included pain, Knee Society clinical and functional score, range of motion, and need for revision...

Distal femoral varus osteotomy is a well-described treatment option for patients with valgus malalignment associated with a variety of underlying conditions. This procedure may be the definitive treatment option in active patients with isolated lateral compartment osteoarthritis or posttraumatic arthritis. It may be a useful concomitant procedure in young patients with lateral meniscus deficiency, focal chondral defects, chronic medial collateral ligament insufficiency, and/or patellofemoral instability. Distal femoral varus osteotomy can be performed with medial closing wedge or lateral opening wedge techniques...

BACKGROUND: Medial collateral ligament (MCL) bursitis has been described as a distended and inflamed bursa between the superficial and deep portions of the MCL. It is a rare but important cause of medial knee pain. CASE DESCRIPTION: A 65-year-old woman with knee osteoarthritis (OA) presented with severe pain and swelling in her left knee. She didn't have a traumatic injury. After a clinical examination, a slight decrease in the range of motion of the left knee, and a painful swelling and tenderness over the medial side of the knee and proximal tibia were detected...

The lateral collateral ligament is the primary varus stabilizer of the tibiofemoral joint. Diagnosing an injury to this ligament can be challenging in the setting of multiligamentous trauma; however, failure to recognize these injuries can result in instability of the knee and unsatisfactory outcomes after cruciate ligament reconstruction. Recent literature exploring the anatomy and biomechanics of the lateral collateral ligament has enhanced our understanding and improved diagnosis and management of these injuries...

Medial unicompartmental knee arthroplasty (UKA) is an accepted treatment for isolated medial osteoarthritis. However, using an improper thickness for the tibial component may contribute to early failure of the prosthesis or disease progression in the unreplaced lateral compartment. Little is known of the effect of insert thickness on both knee kinematics and ligament forces. Therefore, a computational model of the tibiofemoral joint was used to determine how non-conforming, fixed bearing medial UKA affects tibiofemoral kinematics, and tension in the medial collateral ligament (MCL) and the anterior cruciate ligament (ACL) during passive knee flexion...

INTRODUCTION: The Less Invasive Stabilisation System (LISS) is an angle-stable plate that enables treatment of distal femoral comminuted and periprosthetic fracture. As it is placed through a minimally-invasive lateral approach, lateral knee pain is a commonly described symptom after its application. This study investigates knee lateral collateral ligament (LCL) iatrogenic injury during LISS plate fixation. A cadaver study was performed and a retrospective radiological investigation with the analysis of its clinical application was conducted to evaluate possible knee LCL damage...

A novel biomechanical test bench has been developed for in-vitro evaluation of the knee joint. The test bench allows the kinematics of the knee joint to be studied in all six degrees of freedom. Flexion-extension knee movements are induced by quadriceps and hamstring muscle forces simulated by five pneumatic cylinders. The kinematics of the knee and the actively applied muscle forces are measured simultaneously. The aim of this study was to validate the sensitivity and reproducibility of this novel test bench...

BACKGROUND: Failure rates of knee ligament surgery may be high, and the impact of osseous alignment on surgical outcome remains controversial. Basic science studies have demonstrated that osseous malalignment can negatively affect ligament strain and that realignment procedures may improve knee joint stability. HYPOTHESIS/PURPOSE: The purpose of this review was to summarize the clinical evidence concerning the impact of osseous malalignment and realignment procedures in knee ligament surgery...

BACKGROUND: Coronal deformity correction with total knee arthroplasty (TKA) is an important feature in the treatment of osteoarthritis (OA). The hypothesis of this study was that bone morphology would be different in varus and valgus deformity, both before osteoarthritis development as well as during and after the disease process of OA. MATERIALS AND METHODS: Retrospective study with measurements on preoperative and postoperative full leg standing radiographs of 96 patients who underwent TKA...

Although rare, posterolateral corner (PLC) injuries can result in sustained instability and failed cruciate ligament reconstruction if they are not diagnosed. The anatomy of the PLC was once thought to be perplexing and esoteric-in part because of the varying nomenclature applied to this region in the literature, which added unnecessary complexity. More recently, three major structures have been described as the primary stabilizers of the PLC on the basis of biomechanical study findings: the lateral collateral ligament, popliteus tendon, and popliteofibular ligament...

The use of platelet-rich plasma (PRP) injections in the treatment of musculoskeletal conditions has become more prevalent in recent years. Current literature has exhibited that PRP injections are relatively safe and can potentially accelerate or augment the soft tissue healing process. This review presents the most current literature update on the use of PRP in the treatment of rotator cuff tears, osteoarthritis of the knee, ulnar collateral ligament tears, lateral epicondylitis, hamstring injuries, and Achilles tendinopathy...

BACKGROUND: The role of the anterolateral capsule (ALC) as a secondary restraint to quantitative rotatory laxity of patients with an anterior cruciate ligament (ACL) injury is currently debated. PURPOSE/HYPOTHESIS: The purpose was to determine the influence of concomitant ALC injuries as well as injuries to other soft tissue structures on rotatory knee laxity in patients with an ACL injury. It was hypothesized that a concomitant ALC injury would be associated with increased rotatory knee laxity as measured during a quantitative pivot-shift test...

OBJECTIVE: To study operative effects for the treatment of multiple ligament injuries of knee joints. METHODS: From 2008 to 2013, 26 patients (17 males and 9 females) with multiple ligament injuries of knee joints were treated surgically. The average age was 40.7 years old, ranging from 29 to 55 years old. All the patients were treated with arthroscopic reconstruction of cruiate ligament with autogenous or allogeneic hamstrings and tendon, and at the same time received repair of medial collateral ligament and lateral collateral ligament, as well as the treatment of exterior and interior complex injuries...

BACKGROUND: There is an on-going discussion whether to operatively treat combined grade II and III lesions of the medial collateral ligament (MCL) with anterior cruciate ligament (ACL) in the acute phase rather than conservative treatment of the MCL lesion with a delayed unitary ACL replacement. Another issue is the question how to technically address these MCL lesions. The aim of this study was, therefore, to analyze the results of simultaneous ACL replacement (hamstrings) in a single-bundle technique with a simultaneous MCL ligament bracing procedure...

Knee dislocation is a relatively rare condition of all orthopaedic injuries. Accompanying multiple ligament injuries are common after knee dislocations. A 41-year-old male presented to the emergency department suffering from right knee dislocation in June 2013. The patient had anterior cruciate ligament, medial collateral ligament (MCL), medial patellofemoral ligament (MPFL) rupture, and lateral meniscal tear. A single-bundle anatomic reconstruction, medial collateral ligament reconstruction, medial patellofemoral ligament reconstruction and meniscus repair were performed in single session...

Proximal tibiofibular joint (PTFJ) instability can be easily missed or confused for other, more common lateral knee pathologies such as meniscal tears, fibular collateral ligament injury, biceps femoris pathology, or iliotibial band syndrome. Because of this confusion, some authors believe that PTFJ instability is more common than initially appreciated. Patients with PTFJ subluxation may have no history of inciting trauma or injury, and it is not uncommon for these patients to have bilateral symptoms and generalized ligamentous laxity...
