ABSTRACT
OBJECTIVE:
Treatment of focal cartilage defects of the humeral capitellum with autologous bone-cartilage cylinders to prevent development of arthritis of the elbow joint. INDICATIONS High-grade, unstable lesions (>â¯50% of the capitellum, grade III-IV according to Dipaola), including those involving the lateral edge of the capitellum and with a depth of up to 15â¯mm. CONTRAINDICATIONS Stable lesions and generalized osteochondritis of the capitellum (including Panner's disease), as well as a relative contraindication for lesions >â¯10â¯mm, as the largest punch has a maximum diameter of 10â¯mm. SURGICAL TECHNIQUE Arthroscopy of the elbow joint, transition to open surgery. First, the size of the cartilage defect in the capitellum is determined. Then, one (or several) osteochondral cylinders (OATS Arthex) are removed, which as far as possible completely encompass the defect zone. Corresponding intact bone-cartilage cylinders are obtained from the ipsilateral proximal lateral femoral condyle, each with a 0.3â¯mm larger diameter via an additive miniarthrotomy. The "healthy" cylinders are then inserted into the defect zone in a "press fit" technique. POSTOPERATIVE MANAGEMENT An upper arm cast in neutral position of the hand for 10-14 days, simultaneously beginning physiotherapy (active-assisted movements) and lymphatic drainage. As soon as painless range of motion (ROM) is restored (goal by week 6), isometric training can be started. Resistance training starts from week 12. Competitive sports are only recommended after 6(-8) months.RESULTS:
The current state of research on the surgical treatment of OCD of the humeral capitellum using autologous osteochondral grafts shows mostly promising results. A recent meta-analysis of 24 studies reports a significantly higher (pâ¯< 0.01) rate of return to sports (94%) compared to fragment fixation (64%) or microfracture and debridement (71%) [41]. However, the increased donor-site morbidity must be taken into account (ca. 7.8%).Key words
