Key Medical Takeaway

In this comprehensive guide, we discuss everything you need to know about ORTHOPEDIC MCQS BANK WITH ANSWER HIP 01. An ed instructional course on orthopedics highlights that revision hip arthroplasty with impaction grafting typically shows an outer regenerated cortex, a middle interface zone of viable bone with cement, and an inner necrotic bone layer. Complications like titanium wear, leading to increased debris and loosening, and patellar problems post-TKA, affecting 8-35% of patients, are also critical areas of study.

ORTHOPEDIC MCQS BANK WITH ANSWER HIP 01

QUESTION 1
ORTHOPEDIC MCQS BANK WITH ANSWER HIP 01

A 67-year-old man is requesting revision surgery because of continued pain in the knee after undergoing a total knee replacement 2 years ago. Examination reveals that the knee is not warm, the incision is well-healed, and the skin has normal coloration and hair formation. No varus or valgus instability is noted, and knee range of motion is 5° to 100°. Laboratory studies show an erythrocyte sedimentation rate of 15 mm/h and a WBC of 5,000/mm3. Aspiration of the knee reveals clear fluid that shows no growth on culture. Radiographs reveal an appropriately positioned cruciate-retaining cemented total knee arthroplasty that is well-fixed. What is the probability that the patient’s pain will be improved with revision surgery?

5%

2

3
40%

4
60%

5
90%

DISCUSSION: The patient has a well-fixed and aligned painful total knee replacement. The success rate of revision knee replacement for pain when no mechanical problem can be identified is approximately 40%. The critical step is to rule out the presence of infection with appropriate laboratory studies and aspiration. If no infection is detected, revision should be avoided.

    Cementation technique has a definite influence on the long-term survival of cemented femoral components. Both clinical and autopsy studies support the use of a cement mantle with a thickness of how many millimeters?

    DISCUSSION: Long-term radiographic analysis of cemented total hips supports the creation of a 2- to 5-mm cement mantle in the proximal medial region. Autopsy studies have shown that the incidence of crack formation was greatest when the cement mantle was less than 2 mm.

    34/. A 73-year-old man is scheduled to have mature heterotopic bone resected from around his left total hip arthroplasty. The optimal management for prophylaxis against the return of heterotopic bone postoperatively is radiation therapy that consists of
1
400 cGy in one dose.
2
700 cGy in one dose.
3
1,000 cGy in five doses.
4
2,000 cGy in 10 doses.
5
3,000 cGy in 10 doses.
