1. In the absence of patellar malalignment , results are optimized when an implant with sound geometric features is used, the prosthesis is appropriately aligned, and the soft tissues are balanced.

2. This article introduce, the CT measurements of patellofemoral malalignment in curent status and value in the clinic.

3. Results: The frequency of malalignment was 10% for the entire group of patients.

4. For fractures without a gap or malalignment, all of the methods of percutaneous screw fixation discussed above are acceptable.

5. The installation error model of the gyroscope integrated is analyzed, and then error calibration model of flexible gyroscope integrated is deduced when malalignment angle is considered.

6. In the presence of this sign, the physician should proceed with a more aggressive physical therapy program and further assess patella malalignment.

7. Experiments were made about analysis of rotor oil film whirl and malalignment faults characteristics based on a flexible rotor test bench.

8. A history of recurrent patellar dislocations suggests the presence of patellofemoral malalignment,(/malalignment.html) which may need to be corrected before patellofemoral arthroplasty.

9. Patellofemoral problems related to soft-tissue imbalance, implant malposition , and extensor mechanism malalignment generally become clinically evident within months of surgery.

10. Patient positioning can affect the relative ease of intramedullary nailing and the incidence of malalignment.

11. Summary of Background Data. Dyspnea and dysphagia are complications of posterior O-C fusion with malalignment, and may be prolonged or occasionally serious.

12. Factors that cause patellofemoral pain include: over use, soft tissue imbalance, and malalignment of lower extremity.

13. Summary of Background Data. It is well known that cervical malalignment after occipito-cervicothoracic fusion may cause dysphagia or, rarely, dyspnea.

14. Conclusions: The results indicate that use of the minimally invasive nail insertion technique (MINIT) significantly decreases the occurrence of malalignment in proximal femoral shaft fractures.

15. The surgeon should not expect that the rotational alignment or geometric constraint of the trochlear component will ensure patellar component engagement in the presence of patellofemoral malalignment.

16. To assess the functional outcome, influence factors and its management of lateral wedge high tibial osteotomy(HTO)in patients with symptomatic lateral thrust and varus malalignment.

17. ConclusionSpinal fixation can increase the stress at the adjacent segment, and lumbar malalignment fixations may further worsen this biomechanical condition.

18. None of the other factors studied had a statistically significant effect on malalignment.

19. Methods The treatment which included joint clearance and lateral retinacular release of knee osteoarthritis with malalignment in patellofemoral joint was evaluated in 34 patients.

20. The effect of the treatment of knee osteoarthritis with malalignment in patellofemoral joint using joint clearance and lateral retinacular release is positive.
