Different effects of the lateral meniscus complete radial tear on the load distribution and transmission functions depending on the tear site
Purpose To compare the effect of the lateral meniscus (LM) complete radial tear at different tear sites on the load distribution and transmission functions. Methods A compressive load of 300 N was applied to the intact porcine knees ( n = 30) at 15°, 30°, 60°, 90°, and 120° of flexion. The LM compl...

| description | Purpose
To compare the effect of the lateral meniscus (LM) complete radial tear at different tear sites on the load distribution and transmission functions.
Methods
A compressive load of 300 N was applied to the intact porcine knees (
n
= 30) at 15°, 30°, 60°, 90°, and 120° of flexion. The LM complete radial tears were created at the middle portion (group M), the posterior portion (group P), or the posterior root (group R) (
n
= 10, each group), and the same loading procedure was followed. Finally, the recorded three-dimensional paths were reproduced on the LM-removed knees. The peak contact pressure (contact area) in the lateral compartment and the calculated in situ force of the LM under the principle of superposition were compared among the four groups (intact, group M, group P, and group R).
Results
At all the flexion angles, the peak contact pressure (contact area) was significantly higher (lower) after creating the LM complete radial tear as compared to that in the intact state (

To compare the effect of the lateral meniscus (LM) complete radial tear at different tear sites on the load distribution and transmission functions.
Methods
A compressive load of 300 N was applied to the intact porcine knees (
n
= 30) at 15°, 30°, 60°, 90°, and 120° of flexion. The LM complete radial tears were created at the middle portion (group M), the posterior portion (group P), or the posterior root (group R) (

The peak contact pressure (contact area) in the lateral compartment and the calculated in situ force of the LM under the principle of superposition were compared among the four groups (intact, group M, group P, and group R).
Results
At all the flexion angles, the peak contact pressure (contact area) was significantly higher (lower) after creating the LM complete radial tear as compared to that in the intact state (
p
< 0.01). At 120° of flexion, group R represented the highest peak contact pressure (lowest contact area), followed by group P and group M (
p
< 0.05). The results of the in situ force carried by the LM were similar to those of the tibiofemoral contact mechanics.
Conclusion
The detrimental effect of the LM complete radial tear on the load distribution and transmission functions was greatest in the posterior root tear, followed by the posterior portion tear and the middle portion tear in the deep-flexed position. Complete radial tars of the meniscus, especially at the posterior root, should be repaired to restore the biomechanical function.</description><identifier>ISSN: 0942-2056</identifier><identifier>EISSN: 1433-7347</identifier><identifier>DOI: 10.1007/s00167-020-05915-8</identifier><identifier>PMID: 32152692</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Animals ; Biomechanical Phenomena ; Biomechanics ; Contact angle ; Contact pressure ; Humans ; Injuries ; Knee ; Knee Injuries - physiopathology ; Knee Joint - physiopathology ; Load distribution ; Load distribution (forces) ; Medicine ; Medicine & Public Health ; Menisci, Tibial - physiopathology ; Meniscus ; Middle Aged ; Orthopedics ; Pressure ; Range of Motion, Articular ; Recovery of function ; Stress concentration ; Stress, Mechanical ; Swine ; Tars ; Tearing ; Tibial Meniscus Injuries - physiopathology ; Weight-Bearing</subject><ispartof>Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2021-02, Vol.29 (2), p.342-351</ispartof><rights>European Society of Sports Traumatology, Knee Surgery, Arthroscopy (ESSKA) 2020</rights><rights>European Society of Sports Traumatology, Knee Surgery, Arthroscopy (ESSKA) 2020.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c441t-ab5bf11ae41240572c4fc049dba2122e144095ef99758310cbaa59db60972a583</citedby><cites>FETCH-LOGICAL-c441t-ab5bf11ae41240572c4fc049dba2122e144095ef99758310cbaa59db60972a583</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://link.springer.com/content/pdf/10.1007/s00167-020-05915-8$$EPDF$$P50$$Gspringer$$H</linktopdf><linktohtml>$$Uhttps://link.springer.com/10.1007/s00167-020-05915-8$$EHTML$$P50$$Gspringer$$H</linktohtml><link.rule.ids>314,776,780,27901,27902,41464,42533,51294</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/32152692$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Ohori, Tomoki</creatorcontrib><creatorcontrib>Mae, Tatsuo</creatorcontrib><creatorcontrib>Shino, Konsei</creatorcontrib><creatorcontrib>Fujie, Hiromichi</creatorcontrib><creatorcontrib>Hirose, Takehito</creatorcontrib><creatorcontrib>Tachibana, Yuta</creatorcontrib><creatorcontrib>Yoshikawa, Hideki</creatorcontrib><creatorcontrib>Nakata, Ken</creatorcontrib><title>Different effects of the lateral meniscus complete radial tear on the load distribution and transmission functions depending on the tear site</title><title>Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA</title><addtitle>Knee Surg Sports Traumatol Arthrosc</addtitle><addtitle>Knee Surg Sports Traumatol Arthrosc</addtitle><description>Purpose
