JR 101 FINAL EXAM ALL POSSIBLE
QUESTIONS FINAL STUDY GUIDE 2026
SOLVED QUESTIONS FULLY CORRECT
⫸ functional arc range Answer: 10 to 110 degrees
⫸ what is the functional axis a combination of Answer: the longitudinal
axis of the tibia (int/ext rot.) and the flex/ext. axis of the femur
⫸ deep flexions is active or passive Answer: active
⫸ slope of the tibia? implications? Answer: sloped lateral to medial;
(lateral higher) because the tibia is cut straight this affects the space,
therefore mored needs to be taken off the medial femoral condyle. helps
keep ligaments at length
⫸ 3 things the single radius gives patietns and customers Answer:
satisfaction, surviorship and stability
⫸ what is design purpse of single radius? Answer: designed to address
stability during active flexion where the majority of motion occurs
, ⫸ Single radius takeawys Answer: the persepctive of the TEA
transepicondylar axis has allowed researchers a more accurate
persepctive of knee motion
⫸ what is a knee impant with multiple radia called? Answer: a J curve
⫸ Stryker Triathlon system is built around a circular single radius
allowing for Answer: -constant ligament tension and stbaility in flexion
- enhanced stability throughout the active ROM
⫸ how much less quad strength with use of smooth rotating single axis
Answer: 57%
⫸ what is the patellofemoral offset? Answer: distance between the
center of the knee and the patella
⫸ PS impplant takes less Answer: bone
⫸ flared condyles are designed to Answer: internally and externally
rotate by 20 degress throughout the ROM
⫸ Cam of the PS femur does.. Answer: enganges the posterior tibia at
45 degress like the PCL where natural loading occurs
⫸ 4 implant options Answer: CR - cruciate reatining
