Abstract
|
BACKGROUND: With incorrect or even without treatment, acute injuries of the posterior cruciate ligament (PCL) can lead to chronic instability of the knee joint. After delayed treatment, negative occupational changes and reduced quality of life can occur. These aspects have not yet been investigated. The purpose of this study was to evaluate occupational consequences after isolated reconstruction in cases of chronic PCL insufficiency.
FINDINGS: 12 patients treated with PCL reconstruction in a single bundle technique, using hamstring tendon grafts, were evaluated. All patients were operated upon at least 3 months after injury. Mean time of follow-up was 51 ± 18.2 months (14-75). Radiological assessment (Telos stress device) showed a side comparison of total translation of 4.5 ± 2.6 mm. Occupational consequences have been evaluated by the classification system "REFA". Median time incapacity for work was 8 weeks. Nearly all patients achieved the mental status of the normal population (SF-36), but physical status was still restricted. A pre- to postoperative improvement of the clinical scores could be seen: Lysholm-Score: 46.4 ± 17.3 to 84.7 ± 14.1, HSS-Score: 74.3 ± 10.5 to 88.3 ± 10.7. Postoperative evaluated scores were: Tegner score: 4.8 ± 1.2, IKDC score: 80.0 ± 16.2, VPS: 3.4 ± 2.7. Patients with low physical load in their workplace described significantly better clinical results in every clinical score (p < .05) and less pain than patients with high physical load prior to the accident (VPS: REFA < 2: 2.4 ± 2.6, REFA ≥ 2: 5.5 ± 1.7; p < 0.05).
CONCLUSIONS: Operative treated patients with a chronic PCL insufficiency achieve an improvement of the clinical result. Patients with low physical load at their workplace achieve less restrictions.
