Technical Tips and Tricks for Knee Osteotomy.

Osteotomies around the knee have a variety of indications, including pain reduction, functional improvement, knee joint stabilization, and articular cartilage preservation. Thorough preoperative planning is essential, including a determination of the precise location of any deformity (proximal tibia, distal femur, or both). High tibial osteotomies and distal femoral osteotomies can be performed in isolation, or jointly in the form of a double-level osteotomy, for correction of coronal and/or sagittal deformity of the knee.

Scientific studies have signified the importance of trochlear resection on the knee extensor mechanism, and dysplasia can be addressed by a groove-deepening trochleoplasty. Alternatively, tibial tubercle anteriorisation has been proposed to reduce patellofemoral joint (PFJ) pressure and alleviate pain from osteoarthritis.
View Article and Find Full Text PDFBackground: Trochleoplasty has shown promising results in selected patients with patellar instability. However, concerns persist regarding its potential relationship with long-term osteoarthritis (OA) and the underlying causes.
Purpose: To evaluate the correlation between postoperative patellofemoral incongruence after trochleoplasty and long-term OA.
Article Synopsis
- The study aims to refine the D. Dejour trochlear dysplasia classification by using quantitative MRI measurements to enhance objectivity and repeatability.
- Researchers analyzed adult knee MRIs to establish thresholds for sulcus angle and lateral trochlear inclination, leading to a classification system that differentiates levels of trochlear dysplasia based on MRI findings.
- The new classification demonstrates high sensitivity (87%) for diagnosing objective patellar instability and achieves excellent interobserver agreement, indicating its reliability for clinical use.
Medial orientation of the trochlear groove is a strong indicator of high-grade trochlear dysplasia.

Purpose: The objective is to evaluate the orientation of the trochlear groove in patients with objective patellar instability (OPI) compared to a control group. The hypothesis is that the trochlear groove angle (TGA) is correlated with the severity of the trochlear dysplasia.
Methods: From 2019 to 2023, magnetic resonance imaging of 82 knees with OPI were compared with 82 control knees.
