– Anteromedial Portal: – for visualization of the lateral compartment, and instrumentation of the the medial compartment; – this portal is located in a manner similar to the anterolateral portal, that is, 1 cm above the medial joint line and 1 cm medial to the edge of the patellar tendon; … Read more
– Discussion: – pts knee is acutely and forcibly flexed; – to check the medial meniscus examiner palpates posteromedial margin of joint with one hand while grasping the foot w/ other hand; – keeping the knee completely flexed, the leg is externally rotated as far as possible and then the knee … Read more
– Discussion: – by definition, invovles RTC tears of more than 5 cm and involves more than than one tendon; – further, massive tears cannot be repaired w/o excessive tension after lysis cuff adhesions and release of the coracohumeral ligament; (see cuff mobilization) – Management: … Read more

– Discussion: – lunate shaped spacer implant made of silicone, vitallium, acrylic, or rolled-tendon is inserted into theresulting space to prevent migration of other carpal bones; – due to the high rate of synovitis, most surgeons are now reluctant to use lunate implants; – Technical Considerations: – dorsal approach is … Read more
– Discussion: – involves central or peripheral depression of frx of lateral plateau w/o associated lateral wedge fracture; – it usually occurs from minimal impact on weak osteoporotic bone; – commonly affects older age groups (55-60 yrs) w/ marked osteoporosis; – stability of joint is rarely affected & excellent … Read more
– See: Retinacular Release for TKR: – Discussion: – see lateral anatomy of the knee and blood supply to the knee; – lateral release detaches patella from lateral soft tissue structures, including lateral retinaculum, fibers from tensa fascia lata muscle, & joint capsule; – a successful release should release the lateral … Read more
– Discussion: Type I Fractures: – this is the wedge fracture of a lateral plateau; – it occurs mostly in young people since the dense cancellous bone of lateral plateau resists depression; – “Minimally Displaced Fractures” (from the Holh Classification) – frx shows depression … Read more
– See: – Discoid Meniscus:: – Types of Meniscal Tears; – Discussion: – in shape medial meniscus resembles a C, whereas lateral meniscus is more sharply curved and resembles an O that is unclosed medially; – lateral meniscus is much more of closed circle in uniform width from anterior to posterior; – it has … Read more
– See: – Rolling and Gliding Mechanism: – Gait: – Discussion: – bones forming joint are femur, tibia, & patella; – two femurs converge toward the knee and each tibia is nearly vertical, femur & tibia meet angle of some 5-12 deg; … Read more
