Background: Studies evaluating secondary meniscectomy rates and risk factors for failure of ramp repair are sparse and limited by small numbers and heterogeneity.
Purposes/hypothesis: The purposes were to determine the secondary meniscectomy rate for failure of ramp repair performed using a posteromedial portal suture hook at the time of anterior cruciate ligament reconstruction (ACLR) and to identify risk factors for secondary meniscectomy. It was hypothesized that patients who underwent ACLR combined with a lateral extra-articular procedure (LEAP) would experience significantly lower rates of secondary meniscectomy compared with those undergoing isolated ACLR.
Study Design: Case-control study; Level of evidence, 3.
Methods: Patients undergoing primary ACLR and ramp repair between 2013 and 2020 were included in the study. Final follow-up for each patient was defined by his or her last appointment recorded in a prospective database (with a study end date of March 2023). The database and medical records were used to determine whether patients had undergone secondary meniscectomy for failure of ramp repair. Survivorship of ramp repair (using secondary meniscectomy as an endpoint) was determined using the Kaplan-Meier method. Multivariate analysis was used to investigate possible risk factors.
Results: A total of 1037 patients were included in the study. The secondary meniscectomy rate after ramp repair was 7.7% at a mean final follow-up of 72.4 months. Patients without combined ACLR + LEAP were >2-fold more likely to undergo a secondary medial meniscectomy compared with those with combined ACLR + LEAP (hazard ratio, 2.455; 95% CI, 1.457-4.135; = .0007). Age, sex, preoperative Tegner score, and time between injury and surgery were not significant risk factors for failure.
Conclusion: The rate of secondary meniscectomy after ramp repair performed through a posteromedial portal at the time of primary ACLR was low. Patients who underwent isolated ACLR (rather than ACLR + LEAP) were >2-fold more likely to undergo a secondary medial meniscectomy for failure of ramp repair. Additional risk factors for failure of ramp repair were not identified.

Survivorship and Outcomes of Meniscal Ramp Lesions Repaired Through a Posteromedial Portal During Anterior Cruciate Ligament Reconstruction: Outcome Study With a Minimum 10-Year Follow-up.
Am J Sports Med

Centre Orthopédique Santy, FIFA Medical Center of Excellence, Hôpital Privé Jean Mermoz, Groupe GDS-Ramsay, Lyon, France.
Background: Several studies have demonstrated suture repair of ramp lesions of the medial meniscus via a posteromedial approach was associated with a significantly lower rate of secondary meniscectomy. However, these studies are not long-term and highlight the need for extended follow-up research to better understand the outcomes over a more extended period.
Purpose: To evaluate the long-term results and reoperation rate for the failure of arthroscopic all-inside suture repair of ramp lesions of the medial meniscus via a posteromedial approach during anterior cruciate ligament (ACL) reconstruction.
Windswept deformity of the knee: prevalence and predictive factors in osteoarthritic and healthy populations.
Bone Jt Open

Sydney Knee Specialists, Kogarah, Australia.
Article Synopsis
- This study investigated windswept deformity (WSD) of the knee, focusing on differences between healthy individuals and those with osteoarthritis (OA).
- It involved a detailed comparison of 500 healthy knees and 710 OA knees to measure significant angles related to knee alignment.
- Results showed that WSD was significantly more common in the OA group, with certain factors like meniscectomy and rheumatoid arthritis being linked to its development. *
Inside-Out Repair of Medial Meniscal Ramp Lesions in Patients Undergoing Anterior Cruciate Ligament Reconstruction.
JBJS Essent Surg Tech
October 2024
Twin Cities Orthopedics, Minneapolis, Minnesota.
Article Synopsis
- Medial meniscal ramp lesions occur at the junctions of the medial meniscus and are often found in up to 42% of ACL tears, but commonly go undetected due to limitations in MRI and physical examinations.
- Proper arthroscopic evaluation, including modified techniques, is necessary for effective diagnosis and treatment of these lesions to prevent increased knee instability and potential ACL graft failure.
- The video article outlines a systematic approach to identify and assess ramp lesions, demonstrating an innovative mini-open repair technique during ACL reconstruction surgery.
Injectable decellularized Wharton's jelly hydrogel containing CD56 umbilical cord mesenchymal stem cell-derived exosomes for meniscus tear healing and cartilage protection.

Article Synopsis
- Traditional meniscectomy or suture techniques often lead to unsuccessful self-healing of meniscal tears and can worsen cartilage degeneration and osteoarthritis.
- A new therapeutic approach using CD56 umbilical cord mesenchymal stem cells encapsulated in a modified decellularized Wharton's Jelly hydrogel (DWJH/CD56Exos) has shown promising potential for enhancing meniscal tear healing.
- In both in vitro and in vivo studies, the DWJH/CD56Exos demonstrated excellent biocompatibility, supported chondrogenesis, promoted meniscal tissue regeneration, and helped prevent further cartilage degeneration in the knee.
Arthroscopic partial meniscectomy versus exercise therapy for degenerative meniscal tears: 10-year follow-up of the OMEX randomised controlled trial.

Division of Orthopaedic Surgery, Oslo University Hospital, Oslo, Norway.
Article Synopsis
- - The study aimed to compare the long-term effects of arthroscopic partial meniscectomy (APM) versus exercise therapy on knee osteoarthritis (OA) progression and patient outcomes over a 10-year period.
- - It included 140 participants with degenerative meniscal tears, finding that the APM group had slightly more OA progression, with 23% developing radiographic OA compared to 20% in the exercise group.
- - Ultimately, both treatment methods showed no major differences in OA progression or strength, but both improved patient-reported pain and knee function.
