Managing the meniscus Part 2: Traumatic tear patterns, biologic augmentation, transplantation, innovation and future research

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Acute, traumatic meniscus tears are common and should be repaired whenever possible. However, the biological age of the patient, along with the specific tear morphology, may significantly influence the selection of the repair technique, expected clinical outcomes and the postoperative rehabilitation protocol.

Total Knee Arthroplasty in Severe Valgus Osteoarthritis Excellent Early Results in a 90-Year-Old Patient with a Valgus Deformity of 47°

Case Reports in Orthopedics, 2017
Grade III valgus deformity (tibiofemoral alignment > 20°) is present in only 0.5% of patients receiving total knee arthroplasty. Furthermore, cases with a valgus deformity exceeding 40° are even rarer.

Collagen‐membrane‐covered matrix‐associated chondrocyte implantation improves safety over periosteum‐covered MACI for large knee cartilage defects: A real‐world data analysis in the registry study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This registry study aimed to evaluate the safety and effectiveness of collagen membrane‐covered matrix‐associated autologous chondrocyte implantation (cMACI) versus periosteum‐covered MACI (pMACI) for large knee cartilage defects (Outerbridge III–IV, ≥4 cm²) in the femorotibial and/or patellofemoral joints with a minimum 2‐year follow ...

Joint line obliquity disruption negatively affects mid‐term patient‐reported outcomes following total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The influence of change in coronal alignment on clinical outcomes following total knee arthroplasty (TKA) remains unclear. The Coronal Plane Alignment of the Knee (CPAK) classification can be broken up into arithmetic hip–knee–ankle (aHKA) angle and joint line obliquity (JLO) components, potentially identifying distinct failure ...

Superior patient‐reported clinical outcomes after patient‐individual total knee arthroplasty compared with off‐the‐shelf robotic‐assisted total knee arthroplasty in valgus knee phenotypes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare early patient‐reported clinical outcomes of patient‐individual total knee arthroplasty (TKA) with individualized trochlear design versus robotic‐assisted TKA using off‐the‐shelf implants in patients with valgus knee phenotypes and pronounced femoral valgus (lateral distal femoral angle [LDFA] < 85°) at 3 and 12 months ...

Varus inclination of the proximal tibia or the distal femur does not influence high tibial osteotomy outcome [PDF]

, 2009
We have analysed retrospectively the influence of different sources of knee deformity on failure of closing wedge high tibial valgus osteotomy (HTO). Preoperative frontal plane varus deformities of the lower extremity, distal femur and proximal tibia ...

Weight‐bearing computed tomography reveals greater anterior tibial translation and femorotibial rotation than magnetic resonance imaging in chronic anterior cruciate ligament deficiency: A prospective observational study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare anterior tibial translation and femorotibial rotation measurements obtained from conventional supine, non‐weight‐bearing magnetic resonance imaging (MRI) and weight‐bearing computed tomography (WBCT) in patients with chronic anterior cruciate ligament (ACL) tears. Methods WBCT of the knee acquired in full extension and at 30°

Does Severe Tibiotalar Malalignment Predispose to Worse Midterm Outcomes following TAA?

Foot & Ankle Orthopaedics
Research Type: Level 4 – Case series Introduction/Purpose: Previous studies have suggested that modern total ankle arthroplasty (TAA) implants may be used in the setting of severe tibiotalar malalignment, however midterm results are limited.

The posterior-anterior-flexed view is essential for the evaluation of valgus osteoarthritis. A prospective study on 134 valgus knees

BMC Musculoskeletal Disorders, 2019
Background Radiographic imaging is an important tool to assess osteoarthritis (OA). Lateral compartment osteoarthritis (valgus OA) usually starts with cartilage degeneration along the posterior aspect of the lateral femoral condyle.
