In this retrospective study we have assessed the results of low tibial valgus osteotomy for varus-type osteoarthritis of the ankle and its indications.

We performed an opening wedge osteotomy in 25 women (26 ankles). The mean follow-up was for eight years and three months (2 years 3 months to 17 years 11 months).

Of the 26 ankles, 19 showed excellent or good clinical results. Their mean scores for pain, walking, and activities of daily living were significantly improved but there was no change in the range of movement. In the ankles which were classified radiologically as stage 2 according to our own grading system, with narrowing of the medial joint space, and in 11 as stage 3a, with obliteration of the joint space at the medial malleolus only, the joint space recovered. In contrast, such recovery was seen in only two of 12 ankles classified as stage 3b, with obliteration of the joint space advancing to the upper surface of the dome of the talus. Low tibial osteotomy is indicated for varus-type osteoarthritis of stage 2 or stage 3a.

It has been suggested that arthrodesis of the ankle leads to osteoarthritis of the joints of the ipsilateral hind- and midfoot. We believe these studies overlooked the presence of osteoarthritic changes in these joints before the arthrodesis.

We reviewed the pre-operative radiographs of 70 patients with osteoarthritis of the ankle who underwent 71 ankle arthrodeses (one was bilateral). The talonavicular, calcaneocuboid, subtalar and naviculocuneiform joints were given an osteoarthritis score according to Kellgren and Lawrence. The mean age at operation was 54.9 years and the most common indication was for post-traumatic osteoarthritis (52 cases). A total of 68 patients showed pre-existing arthritis in either the hind- or mid-foot, with the subtalar joint the most commonly affected.

Ipsilateral hind- and mid-foot arthritis is almost universally present in patients with arthritis of the ankle requiring arthrodesis. The presence of such changes may not be a consequence of this arthrodesis.

We reviewed 116 patients who underwent 118 arthroscopic ankle arthrodeses. The mean age at operation was 57 years, 2 months (20 to 86 years). The indication for operation was post-traumatic osteoarthritis in 67, primary osteoarthritis in 36, inflammatory arthropathy in 13 and avascular necrosis in two. The mean follow-up was 65 months (18 to 144). Nine patients (10 ankles) died before final review and three were lost to follow-up, leaving 104 patients (105 ankles) who were assessed by a standard telephone interview. The pre-operative talocrural deformity was between 22° valgus and 28° varus, 94 cases were within 10° varus/valgus. The mean time to union was 12 weeks (6 to 20). Nonunion occurred in nine cases (7.6%). Other complications included 22 cases requiring removal of a screw for prominence, three superficial infections, two deep vein thromboses/pulmonary emboli, one revision of fixation, one stress fracture and one deep infection. Six patients had a subtalar fusion at a mean of 48 months after ankle fusion. There were 48 patients with excellent, 35 with good, 10 with fair and 11 with poor clinical results.

We assessed the long-term outcome of open debridement for the treatment of anterior impingement of the ankle in 27 patients. By using preoperative radiographs to group patients according to both the McDermott and the van Dijk scoring system, we assessed the accuracy of these classifications in predicting outcome. The Ogilvie-Harris scoring system, a visual analogue scale of patient satisfaction, the time to return to full activities, and the ability to return to sports determined the clinical outcome. Follow-up radiographs were used to assess the recurrence of osteophytes. We also assessed the incidence of talar osteochondral lesions at surgery. At a mean follow-up of 7.3 years, 23 of 25 patients (92%) without joint-space narrowing had a good or excellent result. Improvement in the Ogilvie-Harris score was seen in all patients. In athletes, 19 of 24 (79%) were able to return to sports at the same level. Two patients with preoperative joint-space narrowing had a poor result. Osteophytes usually recurred and most patients did not feel that the range of dorsiflexion returned to normal, but symptomatic relief allowed most to return to high-level sport. Our results for non-arthritic joints suggest that this is a safe and successful procedure

We performed a prospective study to assess the long-term outcome of 57 arthroscopic debridement procedures carried out to treat anterior impingement in the ankle. Using preoperative radiographs, we grouped patients according to the extent of their osteoarthritis (OA). The symptoms of those with grade-0 changes could be attributed to anterior soft-tissue impingement alone. Patients with grade-I disease had both anterior soft-tissue and osteophytic impingement, but no narrowing of the joint space. In those with grade-II OA, narrowing of the joint space was accompanied by osteophytic impingement. Radiographs taken before and after operation and at follow-up were compared to assess the recurrence of osteophytes and the progression of narrowing of the joint space. At a mean follow-up of 6.5 years (5 to 8) all patients without OA had excellent or good results. There were excellent or good results in 77% of patients with grade-I OA, despite partial or complete recurrence of osteophytes in two-thirds. In most patients with grade-II OA, narrowing of the joint space had not progressed at follow-up. There was a notable improvement in pain in these patients, 53% of whom had excellent or good results. Although some osteophytes recurred, at long-term follow-up arthroscopic excision of soft-tissue overgrowths and osteophytes proved to be an effective way of treating anterior impingement of the ankle in patients who had no narrowing of the joint space
