Purpose: To evaluate the radiographic and clinical follow-up results of iatrogenic medial collateral ligament (MCL) injuries caused by valgus stress during arthroscopic surgery of the knee.
Methods: This study retrospectively evaluated 15 knees in 15 patients (8 female and 7 male patients), with a mean age of 58 years (range, 45-66 years), with iatrogenic MCL injuries caused by valgus stress during arthroscopic surgery of the knee. All patients were treated conservatively without an immobilizer or brace. The mean follow-up period was 24 months (range, 18-51 months). Evaluations included magnetic resonance imaging immediately postoperatively, as well as physical examinations and valgus stress radiographs (at 0° and 30° of knee flexion) 6 weeks after surgery and at final follow-up.
Results: Postoperative magnetic resonance imaging in all patients showed increased signal intensity, swelling, and partial loss of continuity at the meniscofemoral portion of the MCL. Physical examination showed mild tenderness in only 1 patient after 6 weeks and none at final follow-up. Valgus stress tests and valgus stress radiographs showed no significant differences between the injured and uninjured knees at 6 weeks postoperatively and at final follow-up (P > .05).
Conclusions: Iatrogenic MCL injuries during arthroscopic knee surgery could be treated successfully without a splint or brace.
Level Of Evidence: Level IV, prognostic case series.

Lateral meniscus extrusion on preoperative MRI and its impact upon mid-term clinical outcomes following mobile-bearing unicompartmental knee arthroplasty.

Background: The presence of full-thickness cartilage in the lateral compartment on valgus stress radiography is a criterion for medial mobile-bearing unicompartmental knee arthroplasty (UKA). However, the appropriateness of medial UKA is uncertain when preoperative MRI shows extrusion of the lateral meniscus. We therefore assessed how preoperative MRI-detected lateral meniscus extrusion affects mid-term functional outcomes after mobile-bearing UKA.

Introduction: High tibial osteotomy (HTO) is indicated for managing isolated medial knee osteoarthritis in a young patient with a metaphyseal deformity of the proximal tibia. In a medial open-wedge HTO, maintaining the integrity of the hinge is crucial for consolidation and preservation of the correction. Based on a validated model and preliminary results, the objective of this work was to measure and monitor the distribution of mechanical load on a locking fixation plate and the lateral hinge of an HTO using a finite element (FE) model during different phases of consolidation evolution, simulating single leg weightbearing.

Purpose: Varus posteromedial rotatory instability (VPMRI) involves anteromedial coronoid fracture (AMCF), lateral ulnar collateral ligament (LUCL), and medial collateral ligament (MCL) injury. There is no general consensus regarding the surgical treatment, but most surgeons recommend internal fixation of the coronoid along with primary ligament repair. This methodology involves postoperative immobilization to allow ligament healing, occasionally associated with stiffness.

Objective: To establish a finite element model of the knee joint based on coronal plane alignment of the knee (CPAK) typing method, and analyze the biomechanical characteristics of different types of knee joints.
Methods: The finite element models of the knee joint were established based on CT scan data of 6 healthy volunteers. There were 5 males and 1 female with an average age of 24.
A novel minimally invasive nonanatomical single-bundle medial collateral ligament reconstruction technique with a short isometric construct Achilles tendon allograft: A surgical description with clinical and radiological outcomes in multiligament knee injury patients.

Purpose: Multiligament knee injuries (MLKIs) involve various ligaments in the knee. Current double-bundle anatomical reconstructions of the medial collateral ligament (MCL) increase the level of technical complexity, often resulting in the establishment of numerous bone tunnels and different fixation points with additional hardware. To overcome these limitations, we proposed a novel minimally invasive nonanatomical MCL reconstruction with one tibial tunnel in the metaphysis using Achilles allograft in the MLKI setting.
