Bipartite patella (Superior lateral edge); physis doesn’t close (true bipartite); fracture
Superior Lateral Trochlear Groove/ Ridge (B)
Bony buttress to prevent the lateralisation of the patella. If dislocation/subluxation occurs, we may get OCD from inferior (retropatellar) surface of patella or from lateral trochlea. Also an OATS and Mosaicplasty harvest site (for articular cartilage procedures)

DJD- can feel osteophytes, bone spurs
Femoral Groove/ Sulcus; Trochlear Groove (B)

Lateral Head of Gastrocnemius (ST)
Myositis, -osis, strain, tear/ rupture, and Fabella may be present
Posterior Capsule Area of the Knee (ST)
Swelling; Baker’s cyst
Popliteal Artery (ST)
Primary blood supply down to the foot- can be a defect in vascular supply to lower leg
Medial Tibial Plateau/ Joint Line (B)
Tibial line fracture
Tibial Flair (B)
the most common site of tibial stress fracture
Medial Meniscus (ST)
Tears (usually in the posterior 1/3)
Coronary Fibers (ST)
Correlated to meniscus tears (these fibers are innervated so they will feel pain)
Meniscotibial Capsule (ST)
Pain- holds the meniscus in place
MCL (ST)
Torn (2nd most common to ACL); most commonly at joint line, then proximal jt line, then distal jt line
Pes Group: Semitendonousus (ST)
Tendonitis, -osus, can be used for ACL reconstruction
Pes Group: Gracilis (ST)
Tendonitis, -osus, can be used for ACL reconstruction
Pes Group: Sartorius (ST)
Tendonitis, -osus
Semimembransus (ST)
Tendonitis, -osus
Pes Bursa (ST)
Bursitis
Medial Femoral Condyle (B)
OCD lesions due to AVN
Medial Trochlear Ridge (B)
Osteophytes
Medial Joint Line/ Tibial Plateau (B)
Contusions, fractures, etc.
Medial Femoral Epicondyle (B)
Proximal attachment for MCL- 2nd most commons site for MCL injury; bone avulsion
Adductor Tubercle (B)
Pain from patellar injury
Meniscofemoral portion of capsule (ST)
Pain correlated with meniscal tear
MCL (ST)
Torn (2nd most common to ACL); most commonly at joint line, then proximal jt line, then distal jt line
Medial retinacular fibers (ST)
Can be torn if there was a patellar dislocation or subluxation; retunacular neuromas (defects, rents or bumps)
MPFL (ST)
Stabilizer for the knee
Plica (ST)
irritated: 1. microtraumatic overuse 2. macrotrauma directly to the area 3. chronic effusion in the knee causes degradation changes to the synovium, and it creates a plica syndrome (plica becomes fibrotic/ hard)
Infrapatellar Fat Pad (ST)
Most innervated/ sensitive structure in the knee; Hoffa’s syndrome if it gets inflamed for injured
Lateral Joint Line (B)
Jt pain can correlate with meniscal tears
Gerdy’s Tubercle (B)
Pain can be from insertion problems from the ITB

Lateral Meniscus (ST)
Tears
Lateral Coronary Ligament (ST)

Pain correlates with meniscus tears
LCL (ST)

Anterior Proximal Tib Fib Ligament (ST)
Stabilization ligament- important for hypermobility
Posterior Proximal Tib Fib Ligament (ST)
Stabilization ligament- important for hypermobility
Peroneal Nerve (ST)
Can get hit there or affected by varus LCL injury

Lateral Retinaculum (ST)
Tears, retinacular neuromas
Infrapatellar Fat Pad (ST)

Popliteal Tendon (ST)
Overuse
Anterior Lateral Ligament (ST)
Helps to counter some of the micro transverse plane rotation that occur after an injury
