Zusammenfassung
Hintergrund
Geringe postoperative Schmerzen, eine rasche Rehabilitation, kurze stationäre Liegezeiten sowie eine kaum gestörte Achsenkinetik bilden die Vorteile der unikondylären Versorgung von medialen Arthrosen. Notwendige Voraussetzung hierfür sind eine muskuläre und ligamentäre Stabilität. Bei biologisch jungen, aktiven Patienten (<60 Jahre) mit einer isolierten medialen Gonarthrose und zusätzlicher vorderer Kreuzbandinsuffizienz ist der unikondyläre Gelenkersatz kontraindiziert. Um in diesen Fällen die Vorzüge der unikondylären Endoprothese bei lokalisierter Arthrose nutzen zu können, ist die Wiederherstellung der Bandstabilität notwendig.
Material und Methoden
Mit diesem Ziel implantierten wir an ausgewählten Patienten eine unikondyläre Endoprothese und führten zusätzlich eine vordere Kreuzbandplastik durch. Von 2003–2006 operierten wir 32 Fälle mit dieser Kombinationsoperation und untersuchten sie in einem Follow-up von 31 (10–38) Monaten nach.
Ergebnisse
Der Knee-Society-Score (KSS) erhöhte sich signifikant von präoperativ durchschnittlich 83,2 (44–103) auf 167,6 (145–177) nach 31 (10–38) Monaten (Wilcoxon-Test, p<0,05).
Schlussfolgerung
Wenngleich Langzeitergebnisse fehlen und größere Patientenkollektive für fundierte Aussagen unabdingbar sind, ermutigen die erfolgreiche Rehabilitation und die Steigerung im KSS und könnten somit Anlass zur Erweiterung des Indikationsspektrums für den unikondylären Oberflächenersatz geben.
Abstract
Background
Low postoperative pain level, decreased length of hospital stay and accelerated rehabilitation are the major benefits of unicondylar knee arthroplasty. Especially in comparably young, not yet retired and still active patients with an isolated medial gonarthrosis, these prostheses offer many advantages. However, one important requirement to be treated with such implants is a well functioning stability system of the muscles and ligaments. Thus in patients with degenerated or destroyed anterior cruciate ligaments it is contraindicated to use this method. In order to still take advantage of this therapy for treatment of isolated arthrosis, reestablishment of the proprioceptive structures through simultaneous or staged ACL reconstruction is mandatory.
Patients and methods
Pursuing this goal we performed unicondylar knee arthroplasty with simultaneous ACL reconstruction on eligible patients. Between 2003 and 2006 we treated 32 knees with this combined surgery and followed them for a mean of 31 months (range: 10–38).
Results
The mean Knee Society Score significantly improved from 83.2 (44–103) to 167.6 (145–177) at a mean follow-up of 31 months (10–38).
Conclusions
Preliminary results of this short-term follow-up are promising. Especially the predominant number of patients who were able to return to work soon after rehabilitation and the significantly improved score postoperatively reflect the benefits of this prosthesis system in select patients. However, long-term follow-up and larger case numbers are necessary to confirm these encouraging results in the future.
