Aims

To determine whether platelet-rich plasma (PRP) injection improves outcomes two years after acute Achilles tendon rupture.

Purpose: Methods: Evaluation of the results of arthroscopic ankle arthrodesis, performed in 49 consecutive patients (52 ankles), with disabling ankle arthritis, between 08/1998 and 12/2004. Thirty ankles had no significant deformity (group A), whereas 22 ankles had a varus or valgus deformity greater than 10° (mean 21.7°, max 45°) (group B). Mean age in groups A and B was 49.7 and 57.5 years respectively (p=0.15). The primary diagnosis in groups A and B was post-traumatic arthritis in 66% and 27% and idiopathic osteoarthritis in 17% and 59%, respectively. Average hospital stay was 3.63 and 3.68 days in groups A and B respectively (p=0.96). Postoperative treatment included ankle immobilization for 3 months. Progressive weight-bearing was initiated at two weeks. Mean follow-up was 14.9 months (range 6–60). Results: No infections or neurovascular problems occurred. Fusion occurred in 29/30 cases in group A at an average time of 11.52±5.2 weeks and in 21/22 patients at 11.67±2.3 weeks in group B (p=0.89). Not planned surgical procedures were required in eight cases (15.4%). Symptomatic arthritis from the adjacent joints developed in three cases during the follow-up period. The arthrodesis position angle measured in the sagittal plane from the lateral post-operative plane film averaged 105°±3° and 103°±6° in groups A and B respectively (p=0.27). The outcome in groups A and B was graded as very good in 73% and 72.7%, fair in 23% and 22.7% and poor in one case in each group, respectively (p=0.26). Conclusions: The arthroscopic technique offers a high fusion rate, decreased time to fusion, short hospital stay and absence of limb-threatening complications. Deformity correction can be attempted with equally good results

Aims

Arthroscopic microfracture is a conventional form of treatment for patients with osteochondritis of the talus, involving an area of < 1.5 cm². However, some patients have persistent pain and limitation of movement in the early postoperative period. No studies have investigated the combined treatment of microfracture and shortwave treatment in these patients. The aim of this prospective single-centre, randomized, double-blind, placebo-controlled trial was to compare the outcome in patients treated with arthroscopic microfracture combined with radial extracorporeal shockwave therapy (rESWT) and arthroscopic microfracture alone, in patients with ostechondritis of the talus.
