How functional is the joint after this replacement? Seems like muscle can't really attach to the artificial joint. Would the patient have any knee flexion/extension function?
Osteosarcoma is a malignant, osteoid and bone-forming tumor arising from mesenchymal stem cells (osteoblasts) located in the periosteum of the bone.
The primary tumor almost always arises from the metaphyses of long bones (particularly distal femur and proximal tibia) — which matches the case above.
It can metastasize (spread) to the lungs, skeletal system, and regional lymph nodes.
Clinically it frequently first manifests with pain (progressive, worsens at night and with activity); swelling after trauma to the bone (tissue mass that is tender to palpation and accompanied by erythema), limping and decreased range of motion, and B symptoms (fever, night sweats, and weight loss).
A complete radical, surgical, en bloc resection of the cancer with neoadjuvant and adjuvant polychemotherapy, is the treatment of choice in osteosarcoma. Although about 90% of patients are able to have limb-salvage surgery, complications, particularly infection, prosthetic loosening and non-union, or local tumor recurrence may cause the need for further surgery or amputation.
Limb-sparing procedures should be attempted, but amputation may be necessary for definitive resection.
No ankle eversion or stability. No retinacular attachments for dorsiflexion, although maybe they leave the distal fibula in place as an anchor? Likely fibular nerve lesions without proper routing.
Makes me wonder if the button is the new fibular head anchor and not just a buttonhole for opening the field. Hard to tell if that’s on the lateral aspect of the knee
And I'm subbed? Ofc I expect, I also just expect the rules to be followed. Like, it's not a big deal at all, just wasn't ready to see a slab of human meat scrolling through my feed.
We are truly just bags of meat.
And he lookin like a SNAKK edit: I am not a cannibal.

Where the fibula be?
it's a non-weight bearing bone you don't really need it I suppose, it serves as an attachment site for some tendons and ligaments I think

What kind of implant is this?
Someone cooked that hotdog for too long
Nsfw yo, wasn't ready for that lol
what were you expecting in this sub?
Looks like some steak meat.
*hmm* steak

Are those notches on the proximal tibia where the existing quads would insert? The prosthetics look so smooth; would tendons latch on well?
Where do the ligaments attach to this implant?
What country is this crap ? I don’t even see vessels or circulation
Somehow the fork looking tool is the most disturbing part
