MSK examinations can be difficult to remember and they have special tests too. A tip I got was to think about what's in the joint and go according to that.
Shoulder: you start off with the compound movements (hands behind head and elbows out/ hands behind back and reach up spine)
Active and passive movements.
Special tests (there's 4 rotator cuff muscles). Supraspinatus is empty can test and painful arc. Infraspinatus and teres minor for external rotation with elbows at 90 degrees. Subscapularis is hands behind back and lift off test. As an extra, there's a scarf test for the acromioclavicular joint, putting your arm across your neck and resistance is applied to the elbow.
Knee: sweep test and patellar tap for effusions. Flex, extend, hyperextend. There's quite a few tests here. ACL: anterior drawer test, PCL: posterior sag and posterior drawer test. LCL: varus stress test, MCL: valgus stress test. Medial and lateral meniscus: McMurray's test flex and extend knee with rotation (medial: external rotation, lateral: internal rotation)
