– Sequential Order of Release: – PCL: (posterior stabilized prosthesis is generally required); – LCL – in general, sepquential elevation of the femoral origin of the LCL is performed prior to release of other structures because … Read more
– See: – TKR Menu: – Collateral ligaments: – Medial Collateral Ligament – Lateral Collateral Ligament – Discussion: – more common in females; – in valgus knee, ligament balancing is more difficult to fix; – the anatomic deformity is usually larger in valgus than in varus, and it is on the femoral side; – femur … Read more
– See: – Revision TKR: – TKR Menu – Discussion: – asymmetrical bone loss often occurs in the proximal tibia; – CT scan have shown that once one get more than 1 cm below joint line quality and quantity of the supporting cancellous bone diminishes precipitously; – equally important, attachments of iliotibial band, pes anserinus, … Read more

– Discussion: – see flexor tendon repair – see FDP lacerations: FDS and FDP – almost all tendon injuries in zone 2 are due to lacerations; – this is where 2 tendons enter fibro-osseuous tunnel at mid-palm level; – once the FDS and FDP tendons enter flexor tendon sheath, the FDS separates into 2 … Read more
– Discussion: – comminuted fractures of the entire head; – classification: – type A: – fracture of the entire radial neck, with the head completely displaced from the shaft; – type B: – articular fracture involving the entire head, which consists of more than two large fragments; – each fragment is completely displaced from the … Read more
– See: – FDP Avulsion – FDP Lacerations – tendon pull thru technique – Anatomy: – in zone 1, FDP has emerged from between & beneath decussating FDS and travels to its insertion in the distal phalanx; – zone 1 contains: A4, C3, … Read more
– Discussion: – slope of “stress/strain” curve (below yield point) denotes material’s stiffness; – steeper the curve, the stiffer material, gradient is known as modulus of elasticity or Young’s modulus; – in the elastic range of the stress strain curve it is the slope
– See: – PreOp Planning: – TKR Menu – Lateral View: – note if AP size of lateral femoral condyle > medial condyle; – w/ large discrepancy of small degree of Internal Rotation may be necessary to prevent undercutting anterior cortex; – careful preoperative planning, using templates & … Read more
