First revision ACL reconstruction combined with tibial deflexion osteotomy improves clinical scores at 2 to 7 years follow-up.

PURPOSE: To report outcomes of first revision anterior cruciate ligament reconstruction (ACLR) with tibial deflexion osteotomy (TDO) in patients with posterior tibial slope (PTS) >10° at >2 years. METHODS: The authors studied outcomes of a consecutive series of 16 patients that underwent first revision ACLR with TDO, including Lysholm score, IKDC subjective and objective scores, Lachman test, PTS, and signs of osteoarthritis. One woman was excluded because of early signs of knee arthritis, as the first revision ACLR took place 27 years following the primary ACLR. This left a final cohort of 15 patients assessed at minimum follow-up of 2 years. RESULTS: The final cohort comprised 14 men and 1 woman aged 25.3 ± 6.6 years (range 16-39) at first revision ACLR. At final follow-up of 4.4 ± 1.5 years (range, 2-7), PTS was corrected from 12.5 ± 1.8° (range 8-15°) to 1.9 ± 3.6° (range - 4 to 8°), and none of the knees had radiographic signs of osteoarthritis. Lysholm score was 83.8±12.5, IKDC subjective score was 80.3±16.2, and IKDC objective score was A in 5 (33%), and B in 10 (67%). The net improvement exceeded the minimal clinically important difference (MCID) in 93% of patients for the IKDC subjective score and in 80% of patients for the Lysholm score. None of the knees had any retears, and only one required a reoperation to re-suture a medial meniscal tear due to trauma. CONCLUSION: At 2-7 years following revision ACLR combined with TDO, net improvement exceeded the MCID in 93% of patients for IKDC subjective score and in 80% of patients for Lysholm score, with no retears or major complications. These results suggest that TDO is a safe technique to protect the ACL graft and might be considered as of first revision ACLR to correct excessive PTS. LEVEL OF EVIDENCE: Level IV.

Impact of smoking cessation on healing after foot and ankle surgery.

INTRODUCTION: Perioperative smoking is the main risk factor for the development of postoperative cutaneous wound healing complications. We require that all patients undergoing elective foot and ankle surgery stop smoking (6 weeks before and 3 months after) and this abstinence is monitored with a preoperative cotinine test. We therefore wanted to understand how this impacted wound healing in elective foot and ankle surgery: do wounds heal differently in patients who quit smoking for surgery, former smokers and nonsmokers? HYPOTHESIS: Our hypothesis was that patients who stopped smoking for an upcoming surgery had the same wound healing complications as nonsmokers and former smokers. MATERIALS AND METHODS: This was a historical, single-center, single-surgeon cohort study of adult patients who underwent an elective ankle or foot surgery between June 2016 and July 2017. Patients were divided into 3 groups: group 1 smokers who stopped for surgery, group 2 former smokers, and group 3 nonsmokers. The primary endpoint was the occurrence of wound healing complications during the wound care consult scheduled 3 weeks after surgery. RESULTS: A total of 256 patients with a mean age of 58±14.2 years (range, 18-88) were included. Group 3 had more women and a lower BMI than the other groups, but all the other demographic characteristics were similar. Smoking cessation was achieved in group 1 on average 2.5±1.3 months (range, 1-6) before surgery. There were a total of 20 wound healing complications or 7.5% of the cohort: 13% in group 1, 11.1% in group 2 and 6.4% in group 3. The univariate analysis found that the odds ratio was 2.3 when comparing Group 1 to Group 3 and 1.85 when comparing group 2 to group 3 (p=413). No significant risk factors for wound healing complications were found. DISCUSSION/CONCLUSION: Smoking cessation for foot and ankle surgery seems to limit the risk of wound healing complications, with results close to those of former smokers and nonsmokers. Mandatory smoking cessation before surgery could be one of the solutions to prevent this frequent complication. LEVEL OF EVIDENCE: III.

Arthroscopic lateral ankle ligament reinsertion with reinforcement by a minimally invasive extensor retinaculum flap for chronic ankle instability.

The past decade has seen the development of numerous arthroscopic techniques for ankle ligament repair or reconstruction in the treatment of chronic lateral ankle instability. Arthroscopy allows the assessment and treatment of intra-articular pathologies and is associated with faster functional recovery. The open surgery technique described by Blanchet, combining reinsertion of the lateral collateral ligament with reinforcement by an extensor retinaculum flap, has long proven its effectiveness. The aim of this article is to describe this technique under arthroscopy.

Tibial slope correction combined with second revision ACLR grants good clinical outcomes and prevents graft rupture at 7-15-year follow-up.

PURPOSE: To update previously published outcomes (at 2-8 years) of second revision anterior cruciate ligament reconstruction (ACLR) combined with tibial deflexion osteotomy (TDO), after an interval of 5 more years (at 7-15 years), and monitor evolution of clinical scores and progression of osteoarthritis. METHODS: The initial retrospective consecutive series included nine patients that underwent one-stage second revision ACLR with TDO, all of whom were contacted for second follow-up at minimum 7 years. An independent observer collected IKDC-SKF, the Lysholm score, and assessed radiographs for signs of osteoarthritis. RESULTS: Of the nine original patients, seven were assessed at the clinic, one could only be assessed by telephone, and one was lost to follow-up. At final follow-up of 9.9 ± 3.0 years, the eight patients assessed maintained or improved clinical scores, compared to the previous follow-up at 4.0 ± 2.9 years. The mean Lysholm score improved from 73.8 ± 5.8 (65-82) to 84.5 ± 11.9 (59-95), and IKDC improved from 71.6 ± 6.2 (62-79) to 82.9 ± 12.1 (61-98). Of the three patients that had signs of arthritis at the previous follow-up, the stage of osteoarthritis increased in one (from grade 2 to grade 3), remained unchanged in one, and could not be assessed in one. CONCLUSION: At 7-15 years following second revision ACLR with TDO, patients maintained or improved clinical scores compared to the previous follow-up at 2-8 years, without retears or reoperations. Although eight of the nine knees had meniscectomies or meniscal sutures, osteoarthritis progressed in only one of the six knees that had signs of arthritis at the previous follow-up. These results confirm that TDO can protect the ACL graft from retear, with minimal progression of osteoarthritis and/or risks of meniscal tears, suggesting that correction of excessive tibial slope should be considered when performing ACLR, whether a revision or primary procedure.

Return to Sport After Bilateral Single Stage Total Hip Arthroplasty Using the Direct Anterior Approach: A Case Control Study.

BACKGROUND: Total hip arthroplasty (THA) is currently performed on active patients with increasing functional demands. Single stage bilateral THA is indicated in younger patients in good general health. Our objective is to evaluate the return to sport (RTS) in patients who underwent bilateral single stage THA compared to unilateral THA. METHODS: This retrospective case control study was conducted between 2013 and 2017. All patients who underwent bilateral single stage THA were included. The control group had unilateral THA performed and was matched based on age, body mass index, gender, and surgery date (2 controls for each bilateral case). All surgeries were performed by a single senior surgeon using the direct anterior approach. The University of California Los Angeles activity score was collected at the last follow-up. A questionnaire regarding RTS, motivation, and satisfaction was assessed. RESULTS: Thirty-two patients were included in the study, of whom 21 were men. The average age was 60.7 ± 9.6 years, body mass index was 26 ± 4 kg/m2, and mean follow-up was 20.1 ± 11.6 months. Twenty-eight patients overall (87%) returned to sport after the procedure. Twenty-five of these (89%) returned to the same sport, and 17 (68%) participated at the same intensity. The average time to RTS was 4 ± 2.8 months. These results were at least as good as those after unilateral THA. The level of motivation of the patient was the only predictive factor for RTS (P < .001). CONCLUSION: Bilateral single stage THA via a direct anterior approach allows for RTS and to a similar level in the majority of patients in whom this procedure is indicated. LEVEL OF EVIDENCE: Comparative retrospective study, Level III.
