Subchondral lesions are the result of osseous modifications seen in a different array of pathologies such as osteoarthritis, rheumatoid arthritis, calcium pyrophosphate deposition, and osteonecrosis. The physiopathologic changes in all of the aforementioned pathologies are not clear yet. What is clear is that the development of a cystic change in the subchondral bone can cause pain and can lead to modification of the activity of daily life. To provide relief and treatment for such a condition, there are different options with joint replacement as last resort when the cyst develops in communication with the joint; if the cyst is not in communication with the joint, it is possible to perform a bioplasty as we present in this technical report. It is crucial to assess the bone continuity, especially when traumas are reported in the patient history. In our case, the tibial plateau did not have signs of collapse. The technique here presented is a minimally invasive technique that can be reproduced for focal and localized subchondral cysts.

Correlation of Increased Lateral Tibial Slope With Baseline Tibial Position in Intact Knees and Side-to-Side Anterior Tibial Translation for Knees With ACL Tears.
Am J Sports Med
January 2025
Twin Cities Orthopedics, Edina, Minnesota, USA.
Background: Anterior cruciate ligament (ACL) stress techniques-including single-leg stress radiographs, Telos, and KT-1000 arthrometer-are highly accessible and can provide additional diagnostic information to assess ACL and ACL graft integrity. The degree of anterior tibial translation (ATT) may be useful in guiding treatment when a diagnosis on magnetic resonance imaging is not conclusive or for judging if additional treatments, such as anterolateral complex augmentation, may be necessary.
Purpose/hypothesis: The purpose of this study was to evaluate the effect of increasing posterior tibial slope (PTS) on baseline tibial position (BTP) and side-to-side differences (SSD) in ATT.
Effect of ELHLD peptide for stifle function recovery after tibial plateau leveling osteotomy in dogs.

Department of Veterinary Surgery, College of Veterinary Medicine, Konkuk University, Seoul 05029, Korea.
Importance: Patients with arthritis and ruptured cruciate ligaments typically require surgery. Following surgery, it is necessary to improve joint function in early stage.
Objective: This study aimed to investigate the impact of intraoperative intra-articular injection of the ELHLD peptide (L-glutamyl-L-leucyl-L-histidyl-L-leucyl-L-aspartic acid) on postoperative stifle function in patients with medial patella luxation grade 3 and osteoarthritis grade 2 undergoing tibial plateau leveling osteotomy due to anterior cruciate ligament (ACL) rupture.
Medial Meniscus Ramp Tears: State of the Art.
J ISAKOS
December 2024
Twin Cities Orthopedics, Edina, Minnesota, USA. Electronic address:
Medial meniscus ramp tears are tears of the posteromedial capsule or peripheral rim of the posteromedial meniscus that frequently occur with anterior cruciate ligament (ACL) tears. The incidence and prevalence of medial meniscus ramp tears has been increasing in the recent literature due to the increased understanding of the anatomy and diagnosis of these tears. When a patient presents with an ACL tear, a medial meniscus ramp tear should be suspected if the patient has a grade 3+ Lachman or pivot shift exam, a vertical line of increased signal intensity in the posterior capsule or peripheral meniscus on magnetic resonance imagining (MRI), or posteromedial tibial plateau bone bruising on MRI.

Am J Vet Res
January 2025
Department of Companion Animal Clinical Studies, Faculty of Veterinary Science, University of Pretoria, Onderstepoort, Pretoria, South Africa.
Objective: The aim was to investigate the patellar ligament strain with varying degrees of tibial plateau angles (TPAs) after tibial plateau leveling osteotomy (TPLO) in a cranial cruciate ligament (CrCL)-deficient stifle during the stance phase.
Methods: 12 pelvic cadaver limbs were secured to a custom-built jig to mimic a loadbearing stance after which an axial load of 120 N was applied. Patellar ligament strain, change in strain, and percent change in strain were calculated on pre-TPLO (intact and transected CrCL) and post-TPLO tibial TPAs of -5°, 0°, 5°, 10°, and 15°.
Advanced Trauma Care With Tricalcium Phosphate Bone Grafts for Tibial Plateau Fractures: A Report of Three Cases.

Article Synopsis
- Advances in implants and biological therapies have improved trauma care, especially for complex cases like Schatzker type V tibial plateau fractures.
- This study evaluates three patients treated with open reduction and internal fixation plus tricalcium phosphate bone void filler, assessing outcomes through various scoring systems.
- Results showed high patient satisfaction and low pain levels, with good range of motion and no significant complications, indicating that tricalcium phosphate may enhance recovery by supporting healing and integration.
