Purpose: To evaluate the effect of femoral condylar offset and posterior tibial slope on maximal flexion angle of the knee in posterior cruciate ligament (PCL)-sacrificing total knee arthroplasty (TKA, Medial-Pivot Knee System). Materials and Methods: Forty-five knees in 35 patients who could be followed up more than 1 year after PCL sacrificing TKA were evaluated retrospectively. We measured and analyzed the preoperative and postoperative maximal flexion angle, posterior femoral condylar offset difference, posterior femoral condylar offset ratio difference, and tibial slope. Results: The mean maximal flexion angle after TKA was 118.44o±9.8o and significantly related to postoperative tibial slope (11.78o±6.2o) in correlation analysis (R=0.451, p=0.002). There was no statistical relationship between the postoperative maximal flexion angle and the posterior femoral condylar offset difference (3.24±3.862 mm, R=0.105, p=0.493) and posterior femoral condylar offset ratio difference (0.039±0.029 mm, R= -0.163, p=0.284). Conclusions: The maximal flexion angle of the knee after PCL-sacrificing TKA was significantly related to the postoperative tibial slope. Therefore, posterior tibial slope can be considered as a factor that affects maximal flexion angle after PCL-sacrificing TKA.

Purpose: To compare clinical and radiologic results after total knee arthroplasty (TKA) with posterior cruciate sacrificing (PCS) and posterior cruciate substitution (PS). Materials and Methods: Of 66 knees in 53 patients with degenerative arthritis, we completed both practical and radiological evaluations for 27 patients with PCS TKA (30 knees) and 31 patients with PS TKA (36 knees). Results: The knee score improved from 33 to 81.9 for PCS TKA and from 35 to 86.6 for PS TKA. Preoperative flexion was 104.5˚ in the PCS TKA group and 104.7˚ in the PS TKA group. These scores significantly improved to 113.9˚ and 104.7˚ respectively (p<0.05 for each). However, there was no significant difference between the two groups when comparing postoperative results and improvements (p>0.05). On radiological evaluation, the α angle was found to be 98.9˚, the β angle 89.9˚, the γ angle 5.0˚, and the δ angle 39.2˚ for PCS TKA. Also, the α angle was 95.6˚, β angle 89.0˚, γ angle 9.0˚, and δ angle 88.4˚ for PS TKA (p>0.05). Loosening was not encountered in either type. Postoperative complications were few; there was 1 knee (1.5%) with a polyethylene insert spin-out for the PCS TKA group and 1 knee (1.5%) with a periprosthetic fracture for the PS TKA group. Conclusion: On both clinical and radiological evaluations, PCS TKA and PS TKA demonstrated satisfactory results out to 4.5 years of follow up, which also indicated a lack of any significant difference between these two types.

슬관절 전 치환술시 후방십자인대 보존형과 절제형간의 임상적 비교

Purpose : To evaluate the effect of posterior cruciate ligament retaining on clinical results in tota] knee arthroplasty Materials and Methods: Ninety-nine cases(80 patienis) of osteoarthritis were evaluated average 39 months(range 25-98 months) after total knee arthroplasty with LCS. the cases was divided into posterior cruciate retained group I(54 knees) and sacrificed group Il(45 knees). Results: There was no statistically significant difference in H.S.S. knee score(I:87.4±6.3, II:86.1±5.7), range of motion(l:113.7°±19.8°, II:111.9°±10.9°), stability and roent- genographic findings, however, the functional score of the H.S.S. score was higher in group I(l: l8.2±5.6, II:15.3±4.5. p<0.05) and 6 patients with preoperative range of motion below 50 were in group II. 4 patients of 5 bilateral paired patients who ascended and descended stairs with one leg at a time prefer PCL retained side subjectively. Conclusion : We found no significant difference between group I and II in clinical results, however, might be that subjective symptom is excellent in group I and PCL sacrificed design seems to be effective in severely deformed knees and too tight PCL tension.
