I don't have a list for pain causes for the side of the knee but to me the following list illustrates that these things are complicated and require a Dr. Here's a list for pain on the front of the knee (21 listed causes) -

Causes of Anterior Knee Pain
Cause Comment

Articular cartilage injury
May describe history of trauma; mechanical symptoms may occur if loose body present; may have effusion; may have tenderness of involved structure (e.g., femoral condyles, patella)

Bone tumors
Pain may be insidious; may have tenderness of bony structures

Chondromalacia patellae
Retropatellar pain; may have history of trauma; may have effusion on examination

Hoffa's disease
Pain and tenderness localized to infrapatellar fat pad

Iliotibial band syndrome
Typically presents with lateral pain and tenderness over lateral femoral epicondyle

Loose bodies
Symptoms variable; may have intermittent sharp pain, locking, or effusion

Osgood-Schlatter disease
Tenderness and swelling at insertion of patellar tendon at tibial tubercle in an adolescent

Osteochondritis dissecans
Symptoms variable; may have intermittent pain, swelling, or locking

Patellar instability/subluxation
Intermittent pain with sensation of instability or movement of patella; may have swelling; locking can occur with loose body formation; may have tenderness over medial retinaculum

Patellar stress fracture
May have tenderness directly over patella

Patellar tendinopathy
Tenderness of tendon; tendon may be thickened if chronic

Patellofemoral osteoarthritis
May have crepitus or effusion; characteristic radiographic findings

Patellofemoral pain syndrome
Anterior knee pain “behind” or around patella; usually no effusion; may have findings of patellar maltracking

Pes anserine bursitis
Pain usually described as medial rather than anterior; tenderness over pes anserine bursa

Plica synovialis
May be medial or lateral to patella; if symptomatic, tenderness can be demonstrated on examination

Prepatellar bursitis
Characteristic swelling anterior to patella following trauma

Quadriceps tendinopathy
Tenderness over tendon

Referred pain from the lumbar spine or hip joint pathology
Symptoms depend on origin of pain; knee examination usually normal

Saphenous neuritis
Pain usually medial but poorly localized; may have history of surgery

Sinding-Larsen-Johansson syndrome
Tenderness at patellar tendon insertion at inferior pole of patella in an adolescent

Symptomatic bipartite patella
May have tenderness directly over patella with characteristic radiographic findings"
Way to research it! The kid is fine after a week.
