Is There an Association Between Articular Cartilage Changes and Degenerative Meniscus Tears
164
TL;DR: Complex and horizontal cleavage meniscal tears are highly associated with an increased incidence and severity of cartilage degeneration compared with other types of meniscal tear, suggesting that degenerative meniscus tears are not as benign as was previously thought.

Abstract: Purpose: The objective of the present study was to evaluate whether horizontal cleavage and complex meniscus tears, which are degenerative tears, are associated with an increased incidence of cartilage damage, in comparison with patients having other patterns of meniscal injury Type of Study: Case series study Methods: Data were collected prospectively from 497 consecutive knee arthroscopies carried out from 1997 to 2001 Patient data (age, sex, duration of symptoms, injuries, and possible mechanism of injury), operative details (types and number of portals, equipment used), intra-articular findings (articular, meniscal and synovial lesions, and stability characteristics), and procedures performed were recorded Articular lesions were noted on anatomic articular maps of the different functional zones using a system that presaged the current Internal Cartilage Repair Society system Results: A comparison of patients with horizontal cleavage and complex meniscal tears to patients with other types of meniscal tear showed for the former (1) increased incidence of chondral lesions (884% v 696%, respectively, P v 294%, respectively, P v 33%, respectively, P Conclusions: Complex and horizontal cleavage meniscal tears are highly associated with an increased incidence and severity of cartilage degeneration compared with other types of meniscal tears Degenerative meniscus tears are not as benign as was previously thought New age-related categories of chondral damage are emerging Level of Evidence: Level IV, case series prognostic study

TL;DR: Increased levels of pro‐inflammatory cytokines (IL‐6, IL‐8, and TNF‐α) in the chronic phase of meniscal trauma are demonstrated and could be a key factor in hampering cartilage regeneration.
Fatigue life of bovine meniscus under longitudinal and transverse tensile loading.
TL;DR: Results suggest that the non-fibrillar matrix is more resistant to fatigue failure than the collagen fibers, and can be utilized by research groups working to develop meniscus implants with fatigue properties that mimic healthy tissue.
Dynamic Loading Enhances Integrative Meniscal Repair in the Presence of Interleukin-1
TL;DR: Dynamic loading blocked the catabolic effects of IL-1 on meniscal repair, suggesting that joint loading through physical therapy may be beneficial in promoting healing of meniscal lesions under inflammatory conditions.

TL;DR: Meniscal tear and extrusion are associated with increased risk of medial and lateral PFJ OA and more severe meniscal pathology is associated with worsening of PFJOA 2 years later.

TL;DR: This retrospective analysis of 758 meniscal surgeries found articular surface injuries in 35.22% of cases, with degenerative tears and lateral meniscus injuries associated with higher rates of chondral damage and articular surface injuries.

The etiology of chondromalacia patellae
TL;DR: Rubbing of the medial patellar facet on the rim at the upper border of the lateral femoral condyle can explain in part the etiology of chondromalacia.

Knee joint changes after meniscectomy
TL;DR: It seems likely that narrowing of the joint space will predispose to early degenerative changes, but a connection between these appearances and later osteoarthritis is not yet established and is too indefinite to justify clinical deductions.
Meniscal tears: The effect of meniscectomy and of repair on intraarticular contact areas and stress in the human knee A preliminary report
TL;DR: There was no difference in the weightbearing characteristics of the meniscus when repaired by open versus arthroscopic technique when the knee is loaded at 0° flexion, and data suggest that theMeniscus does have a weightbearing role.

TL;DR: Because the horizontal cleavage lesion was so common in the older knee, it must usually remain unrecognised clinically with other factors causing symptoms of night pain and tenderness.
