A case report describes meniscus allograft interposition with bioabsorbable intramedullary pin fixation improving motion and function in a severely contracted PIP joint at 1-year follow-up.
In 148 acute complete PCL injuries, multiligament injury, medial meniscus tear, hyperextension bone bruise pattern, and younger age predicted proximal (vs midsubstance) tear location on MRI.
International Delphi consensus recommends repairing acute and ACL-associated meniscal radial tears (age alone not a contraindication), prioritizing anatomic restoration and conservative early rehab regardless of technique.
Cadaveric testing showed that combining a ramp lesion with a lateral meniscus root tear in an ACL-deficient knee significantly worsens rotational and anterior translational instability compared to either lesion alone.
In 59 patients undergoing combined ACL reconstruction and bucket-handle medial meniscal repair, greater arthroscopic synovial coverage of the ACL graft strongly correlated with meniscal healing, suggesting synovialization as a biological marker of repair success.
Synovial inflammatory phenotypes at ACL reconstruction with meniscal injury predict baseline severity and differential recovery patterns; phenotype-dependent biomarker associations guide prognostication.
In a large database study, meniscal repairs combined with PCL reconstruction had significantly lower failure and revision rates than isolated meniscal repairs, similar to benefits seen with concomitant ACL reconstruction.
Compared to unrepaired medial meniscus root tears, root repair improves function and pain but still leaves residual varus thrust and reduced internal rotation during gait, risk factors for OA progression.
Cadaveric study found that adding one to three centralization sutures during medial meniscus root repair reduced extrusion and contact pressures at specific flexion angles, guiding optimal suture placement pending clinical validation.
FDA adverse event data show all-inside meniscal repair device failures vary by design—all-suture anchors fracture most, capsular-knot anchors have compatibility issues, and meniscal-knot anchors fail during deployment.
Patients with advanced patellofemoral chondrosis had similar patient-reported outcomes after meniscus root repair but nearly 7-fold higher rates of conversion to knee arthroplasty.
MRI detected meniscal ramp lesions far more often (43%) than arthroscopy confirmed (10%) in ACL-injured knees, with stable Greif type 1/2 lesions rarely verified surgically, though posteromedial bone bruising correlated with true lesions.
"The Taco Technique": A Basal Joint Reconstruction Case Series Using a Meniscal Allograft.
In 30 patients, meniscal allograft basal joint reconstruction ('taco technique') reduced pain by ~75% and restored function within about 4 months, with no complications.
In a 15-year survival analysis, meniscal allograft transplantation had 84% survival at 10 years declining to 52% at 25 years, with female sex emerging as an independent risk factor for graft failure after adjustment.
Quantitative MRI mapping of 82 ACL surgery patients showed persistent regional differences in meniscal cross-sectional area and signal intensity versus the contralateral knee that did not normalize even 2 years postoperatively.
Most nonoperatively treated medial meniscus posterior root tears improved clinically despite ongoing structural degeneration, though greater varus alignment (HKA ≥5.5°) predicted later conversion to surgery.
Adding all-inside lateral meniscus posterior root repair to ACL reconstruction did not worsen graft survival or clinical outcomes compared to isolated ACLR, supporting concurrent repair when indicated.
In a simulated meniscectomy study, pituitary rongeurs produced significantly higher finger and thenar forces than Ferris-Smith forceps, suggesting rongeur use may contribute more to surgeon hand/thumb strain.
In ACL-reconstructed knees, steeper tibial slope, flatter medial plateau, smaller lateral meniscal slope, and larger lateral femoral condyle ratio were linked to greater dynamic rotational/translational instability during jump-landing, suggesting possible indications for anterolateral augmentation.
A new 5-type morphology-based classification for radial meniscal tears showed excellent inter- and intraobserver reliability and strong validity against arthroscopy, supporting its use for standardized reporting and treatment planning.
Arthroscopic study of 40 pediatric cadaver knees establishes normal age-based meniscal mobility and rim width benchmarks, showing the lateral meniscus is inherently more mobile than the medial, to help surgeons judge abnormal peripheral rim instability during discoid meniscus saucerization.
Concomitant meniscal repair with ACL reconstruction shows higher subsequent procedures but similar ACL reoperation rates; successful repairs achieve outcomes comparable to isolated ACLR.
Meniscal Dominant Loaders During Simulated Gait: A Cadaveric Study in Human Knees.
Human cadaveric knees distribute joint contact forces heterogeneously during gait; meniscal-dominant loaders comprise 48% of knees with distinct peak stress patterns.
Meniscectomy vs Meniscal Repair: Comparing Rates of Readmission, Reoperation, and Osteoarthritis.
Meniscal repair versus meniscectomy yields similar readmission rates; repair reduces reoperation and subsequent osteoarthritis treatment, favoring preservation.
A posterior tibial slope of 8.3° or greater is associated with lax healing after medial meniscus posterior root repair, predicting less favorable outcomes in these patients.
Evaluation and Management of Meniscal Tears.
Meniscal preservation via individualized repair techniques and selective biologic augmentation is favored over resection, which worsens joint stress and accelerates osteoarthritis.
This review concludes that structured exercise remains a reasonable first-line treatment for degenerative meniscal tears, with arthroscopic partial meniscectomy reserved for patients failing nonoperative therapy.
Medial Meniscal Ramp Lesions: Current Concepts in Diagnosis and Treatment.
Ramp lesions, present in up to 40% of ACL injuries, require systematic posteromedial arthroscopic evaluation and repair when unstable, yielding excellent outcomes and >80% return-to-sport rates.
Biologic augmentation of meniscus repair: A scoping review.
This scoping review of 125 studies found biologic augmentation of meniscus repair—most commonly platelet-rich plasma—is widely used but lacks high-quality evidence to guide specific indications.
Posterior medial meniscus root tear classifications lack consensus; MRI-based systems show good interobserver agreement but arthroscopy-validated accuracy remains limited.
The Long-term Consequence of Anterior Cruciate Ligament and Meniscus Injuries
This review of ACL and meniscus injuries addresses their long-term link to osteoarthritis, the pathogenic mechanisms involved, and the lack of evidence that surgical repair prevents this progression.
Microvasculature of the human meniscus
Cadaveric study of 20 knees mapped meniscal blood supply, showing vascularity limited to the peripheral 10-25% via a perimeniscal capillary plexus, with an avascular zone near the popliteal tendon.
