Are you a scientist? Big call on Troy having genetically weak knees.
Also, are you an orthopaedic surgeon? Another big call on the LARS.
For what it's worth, I am actually a scientist, specifically within genetics, and I've had LARS surgery too.
And what you've said is bunk.
Also, neither of Troy's knee injuries were innocuous, both were impact injuries. It's a big stretch to call that a genetic link, and is not backed up by science.
The actual professionals, (i.e. Julian Feller - one of the most respected in the field) have said Troy's knees are fine.
I don't want Geelong to end up with both Menzels, they will make everyone look fools.
No i am not a scientist.
But as a scientist you would have to agree that the physiologically and biologically the genetic make up and chromasomal link to pre dispositon for injury illness, disease heredation is already founded and proven scientific fact especially including connective tissue disorders,
All tissues in the body are formed of stem cells and dna thus chromosomal defects and genetic variances / malforms predispositions will lead to physiologicacal weakness, malformities, and pre disposition for illnesses or disease, be they auto immune, gentically linked, histological, neurological, haemotalogic, and heredation.
I dont recall Menzell having major trauma to his knees i remember it giving out on him like so many others before and since, innocuous low impact injuries when changing direction and landing jumping etc are what i am on about not having someone crash over your knee Willy T style.
Dodgy Shoulders whilst scary to recruiters are not as scary as major limb fractures and dodgy knees and achilles.
Im betting theres plenty of recruiters chewing their fingernails over this kid and likewise Stringer. For average Joes and veteran athletes they are great, but a number of Orthopods have been less keen as yet to recommend LARS injury dependence of course hence most AFL players still have traditional recos.
There has been studies into heredity and genetic predisposition to connective tissue injuries.
The research has been into into collagen and proteins that make up the connective tissues in partuicular predisposition for Achilles Tendon rupture, Rotator Cuff injuries and dislocations and ACL ruptures, amongst athletes with surprising evidence pointing to increased propensitry amongst female athletes but also identifying a genetic link amongst siblings.

Abstract:
Acute and overuse musculoskeletal soft tissues injuries are common as a result of participating in specific physical or workplace activities. Multiple risk factors, including genetic factors, are implicated in the aetiology of these injuries. Common musculoskeletal soft tissue injuries for which a genetic contribution has been proposed include the Achilles tendon in the heel, the rotator cuff tendons in the shoulder and the cruciate ligaments in the knee. Recent developments in the identification of genetic risk factors for tendon and ligament injuries will be reviewed. Sequence variants within genes that encode for several tendon and/or ligament extracellular matrix proteins have been shown to be associated with specific musculoskeletal soft tissues injuries. Variants within the TNC, COL5A1 and MMP3 genes co-segregate with chronic Achilles tendinopathy. The variant within the TNC gene also appears to co-segregate with Achilles tendon ruptures, while sequence variants within the COL1A1 and COL5A1 genes have been shown to be associated with cruciate ligament ruptures and/or shoulder dislocations. We proposed that genetic risk factors will in the future be included in multifactorial models developed to understand the molecular mechanisms that cause musculoskeletal soft tissue injuries or related pathology. Clinicians could eventually use these models to develop personalised training programmes to reduce the risk of injury as well as to develop treatment and rehabilitation regimens for the injured individual.

Abstract.
Tendons and ligaments within the upper and lower limbs are some of the more common sites of musculoskeletal injuries during physical activity. Several extrinsic and intrinsic factors have been shown to be associated with these injuries. More recently, studies have suggested that there is also, at least in part, a genetic component to the Achilles tendon, rotator cuff and anterior cruciate ligament injuries.
Tears of the rotator cuff and ACL.
In recent years, two studies have reported the investigation of the genetic susceptibility to tears of the rotator cuff and tearing of the ACL.1,20 Both studies provided evidence relating to the genetic contribution of injuries to the rotator cuff and ACL, which were based on clinical information collected from affected individuals, their siblings and matched controls.
September 29, 2010, 12:01 am Phys Ed: Are Bad Knees in Our Genes?
By GRETCHEN REYNOLDS
Are fragile knees inherited? That intriguing question motivated a new study published earlier this month in The British Journal of Sports Medicine, during which researchers looked at one family’s propensity for shredding anterior cruciate ligaments during sports. The report was part of a much larger, ongoing study of risk factors for A.C.L. injury, led by researchers affiliated with the Cincinnati Children’s Hospital and Ohio State University, which involves thousands of young athletes
In the past year, a flurry of new studies have identified several genes that seem to be closely associated with A.C.L. tears.
The gene is known to affect the suppleness of collagen or connective tissue in tendons and ligaments like the A.C.L.
But the emerging genetics of A.C.L. injury do raise the possibility that “in the not-so-distant future we might be able to screen” the DNA of young athletes and find those at highest injury risk, Dr. Hewett said.
For now, the takeaway from the current research is simple. Look to your family. “If you have a first-generation relative, a sibling or parent, who has torn an A.C.L., you are likely to be at above-average risk,” Dr. Hewett said, and might want to investigate the availability of A.C.L. injury prevention programs in your area.
I wouldnt be so sure its all Bunk ........ The Brown twins both ACLs, The Grimes boys chronic hamstring tendons, both Menzels ACLs theres got to be more to it than coincidence looks like there might be.
No i am not a scientist but i am in the medical field.
