Knee pain is one of the most common reasons people in Dhaka and across Bangladesh reduce their activity. In my practice, I see students with sports injuries, office workers with long-standing stiffness, factory workers who stand for hours, and older adults who struggle with stairs. Many people describe knee pain as a simple problem, but the knee is a complex joint. Pain can come from arthritis, cartilage, meniscus, ligaments, tendons, the kneecap, or even from the hip or lower back.
This article explains knee pain causes and treatment in a clear, practical way. My goal is to help you understand what the pain may mean, what evaluation usually involves, which home steps are reasonable, and when urgent orthopedic assessment in Bangladesh is important.
A simple first step: where is the pain and what triggers it?
When I evaluate knee pain, I start with three practical questions:
- Where exactly do you feel the pain: front, inside, outside, or back of the knee?
- What triggers it most: walking, stairs, squatting, sitting, twisting, or sports?
- Is there swelling, locking, giving way, fever, or a recent injury?
These clues often point toward the most likely diagnosis.
Common knee pain causes by pattern
Knee osteoarthritis (wear-and-tear arthritis)
Osteoarthritis is very common, especially after 40. Typical patterns include:
- pain with walking and stairs
- stiffness after rest
- swelling that comes and goes
- gradually reduced movement
In Bangladesh, I often see arthritis worsen faster when patients keep pushing through pain for years without strengthening or weight management.
Meniscus problems (degenerative or injury-related)
The meniscus is a cartilage-like cushion. Meniscus problems can cause:
- pain along the joint line (often inside or outside)
- swelling after activity
- clicking, catching, or locking
Not every meniscus tear needs surgery. Many degenerative tears improve with a structured rehabilitation plan. But true locking, persistent swelling, or mechanical catching may need closer evaluation.
Ligament injuries (ACL, PCL, MCL, LCL)
Ligament injury often follows a twist or trauma. Signs can include:
- a pop at the time of injury
- swelling within hours
- a knee that gives way or feels unstable
If the knee repeatedly gives way, early evaluation is important. Repeated instability can damage cartilage and the meniscus over time.
Patellofemoral pain (kneecap-related pain)
Front-of-knee pain is common in:
- students
- people who climb stairs frequently
- people who sit long hours with the knee bent
Symptoms often worsen with stairs, squats, or sitting for long periods. Many patients benefit from hip and thigh strengthening, movement correction, and gradual activity changes.
Tendon and soft-tissue overload
Knee pain can also come from tendons and surrounding tissue:
- patellar tendon pain (often below the kneecap)
- quadriceps tendon pain (above the kneecap)
- iliotibial band irritation (outer knee pain)
In these cases, pain often relates to overuse, sudden activity increase, or poor movement patterns. Treatment usually focuses on load management, strengthening, and gradual return to activity.
Referred pain from the hip or spine
Sometimes the knee is not the main problem. Hip disease can present as knee pain, and lower back issues can change walking mechanics and worsen knee symptoms. If knee treatment is not helping, the hip and spine should be considered.
