Be more specific since alot can go wrong in the knee.
Unfortunately I could not give you a specific answer.

Well, patella fractures can require ORIF (open reduction interal fixation) where the bone is put together and stabilized with pins, screws, or wires. The symptoms of this fracture would be quite noticeable since the pieces would have displaced and it would take quite an impact. Swelling, bruising, inability to walk, deformity, etc. You would need Xrays to show the fracture.
Then there's ligament tears. There are four ligaments in the knee: the ACL, MCL, LCL, and the PCL. Surgical reconstruction, especially when dealing with athletes, is mostly needed for completely torn ACL or PCL. Also, in most LCL cases as other ligaments are usually damaged. The MCL usually heals well without surgery. Symptoms of ligament tears include swelling, hearing or feeling a pop when the injury happens, sometimes bruising, pain, and instability or giving out of the knee (especially true with ACL tears). Surgery for torn ligaments is called ligament reconstruction (ex: ACL reconstruction). Ligament tears can be tested for by an orthopedist in the office by hands-on maneuvers. However, MRIs are also additionally ordered as they clearly show the inside of the knee and provide a more exact diagnosis.
You will have c-shaped disks of cartilage in your knee that acts as a cushion between your femur and tibia. These are called the mensicus. Larger meniscus tears or tears where there are symptoms are persisting or severe or minor tears that do not get better with physical therapy or rest are treated with surgery. Symptoms of mensicus tears that require surgery include locking of the joint, clicking or popping, gradual swelling, pain, etc. Meniscus tears can also be detected in the office by orthopedists with their hands. However, MRIs are best to diagnose them. If you need surgery for a torn mensicus, it would be either a meniscus repair or meniscus removal.
There is also two tendons that are part of your knee : quadriceps tendon and patella tendon. Ruptures of these are rather rare and would be extremely painful. You would not be able to perform a straight leg raise and there would be a lot of swelling. The patient would also be unable to walk or might have heard a pop when they injured their knee. You would need to have the tendon surgically repaired. A good exam by an orthopedist or ER doctor would probably point to a torn tendon. Xrays or a MRI could also be helpful in diagnosing.
There are also surgeries that are done to change the way the kneecap tracks in the groove at the end of the femur or to prevent it from dislocating again. Symptoms of patella instability include the kneecap slipping out, popping, swelling, pain around the kneecap esp with stairs or prolonged sitting, etc. Surgery for this is usually only done with repeat dislocations or if conservative treatment fails to make the patient better. There are various surgeries for this including lateral release, medial reefing, MPFL reconstruction, tibia turbecule transfer, etc. It can be noticed when there is an obvious patella dislocation (you can see it out of the groove and on the side of the knee), xrays to show how the kneecap sits in the groove, or a MRI. An orthopedist can also detect patella instability with certain hands on tests.
Of course there are also your knee replacements for severe knee arthritis. Xrays can show athritis or a MRI. It would be a major surgery after years of pain and failed attempts at getting better. It's not common in the young, usually people over 60.
There is also knee scopes where surgeons go in and flush the knee and smooth out the cartilage on the ends of the bones. Rough cartilage can cause pain or grinding and other symptoms. People usually try this before a total knee replacement. Sometimes the cartilage is more damaged and requires surgery such as a microfracture (usually an acute chondral injury though).
As you can tell there are many many types of knee surgery since there are so many different structures that make up your knee. It's a complicated joint that is commonly injured especially in athletes. There are other knee surgeries that are as well known such as plica excision or scar tissue removal or patella tendon fenestration. A MRI is best to diagnose knee injuries as it shows all the soft tissues in the knee. Xrays are good for bones. Knee surgery is a common thing although for many knee issues, therapy, bracing, or rest may be attempted first.
Haha bet you got more than you asked for ...hope I helped answer all your questions :)

you tear a ligament
your knee swells, you hear a pop, bruising at some points, unable to bend of fully straighten your knee
there is nothing to call it
