Small tear in the inner knee cushion(Oblique tear of the posterior horn of the medial meniscus)
The back portion of the medial meniscus — the C-shaped cushion on the inner side of your knee — contains an oblique line of bright signal that reaches the joint surface. The tear measures about 8 mm and the rest of the meniscus keeps its normal shape and position.
A tear that reaches the surface means the cushion is no longer perfectly sealed, which is why the inner side of the knee can ache, catch or feel like it briefly gives way. A tear of this size in this location is almost always degenerative — the tissue thinned with age and gave way during ordinary loading — rather than the result of a single injury.
Meniscus tears are found on MRI in roughly 30% of adults over 50, and in a large share of those people the knee causes no symptoms at all.
Bring this finding to your doctor or an orthopaedic clinician. For degenerative tears like this one, guidelines put supervised physical therapy first: several months of strengthening usually settles the pain, and surgery is reserved for knees that stay locked or fail to improve.
Early cartilage softening behind the kneecap(Grade 2 chondromalacia patellae)
The cartilage on the underside of the kneecap shows mild thinning and an uneven surface, without any area where the cartilage is worn down to the bone.
This is early softening of the smooth coating that lets the kneecap glide over the thigh bone. It typically causes a dull ache at the front of the knee that is worse on stairs or after sitting for a long time. At this grade the cartilage is thinner but still covering the bone.
Patellofemoral cartilage changes appear on knee MRI in a large minority of adults over 40, frequently alongside other degenerative findings.
No procedure is needed for this on its own. Quadriceps and hip strengthening is the standard first step, and your clinician can fold it into the same physical therapy plan as the meniscus finding.
Small amount of fluid in the joint(Small joint effusion)
A small volume of fluid sits in the normal recess above the kneecap. The fluid is uniform, and there is no sign of thickened or inflamed joint lining.
A knee that is irritated makes a little extra lubricating fluid — this is the joint reacting to the findings above, not a separate problem. A small, clear effusion of this kind is a routine companion of meniscus and cartilage changes.
Small effusions are seen on a substantial share of knee MRIs performed for pain and are frequently present in knees without any symptoms.
No specific treatment is needed. Tell your doctor if the knee becomes hot, red, rapidly swollen or painful with fever, since those signs point to a different problem.
Start with your primary care physician or an orthopaedic clinic; many plans require a referral before physical therapy, so ask about that on the first call.
Book a routine GP appointment; the GP can refer you to NHS physiotherapy, and some areas allow you to self-refer to physiotherapy directly.
Book a routine appointment with your general practitioner or a traumatologist, following the referral rules of your national health system.
