Effect of simultaneous bilateral surgery or simultaneous arthroscopic ankle lateral ligament repair in hindfoot endoscopic surgery for posterior ankle impingement syndrome in athletes.

BACKGROUND: Posterior ankle impingement syndrome (PAIS) is sometimes complicated by bilateral cases and lateral ankle ligament injuries. Reports on bilateral surgery for PAIS and simultaneous surgery for lateral ankle ligament injury are scarce in the literature. METHODS: We present a 2-year follow-up of 76 athletic patients who underwent endoscopic hindfoot surgery for PAIS. Patients were divided into those who underwent unilateral or simultaneous bilateral surgery and PAIS surgery alone or simultaneous bilateral PAIS surgery without arthroscopic ankle lateral ligament repair. RESULTS: All patients returned to full athletic activities postoperatively. There was no difference in all subscales of the SAFE-Q score between groups except for mean days after surgery for full return to athletic activities. CONCLUSION: Simultaneous bilateral surgery and simultaneous arthroscopic lateral ankle ligament repair had no negative effect on subjective clinical evaluation 2 years after surgery in hindfoot endoscopic surgery for PAIS. LEVEL OF EVIDENCE: III, retrospective case-control study.

Arthroscopic Modified Lasso-Loop Stitch Technique for Chronic Lateral Ankle Instability in Skeletally Immature vs Mature Patients.

BACKGROUND: In recent years, arthroscopic lateral ankle ligament repair has become increasingly popular. However, reports on the clinical outcomes of arthroscopic ankle stabilization for skeletally immature patients remain scarce. This study investigated the clinical outcomes of arthroscopic lateral ankle ligaments repair in skeletally immature patients compared to skeletally mature patients. METHODS: Our retrospective analysis compared skeletally immature patients and skeletally mature adults who underwent arthroscopic repair of the ankle lateral ligaments with a modified lasso-loop stitch using a suture anchor. Skeletal immaturity was defined as patients whose epiphyseal line of the distal fibula remained open on plain radiography. Clinical outcomes were evaluated using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) at 2 years after surgery. The time to postoperative walking, jogging, and return to full sports activities were also evaluated. RESULTS: Sixty-four skeletally immature patients (IM group) and 103 skeletally mature adults (M group) were included. No significant differences were observed during both walking and jogging after surgery between the groups; however, return to full athletic activities was significantly earlier in IM group (P = .05). The mean scores in all SAFE-Q subscales significantly improved in both groups after surgery (P < .001). There were also no statistically significant differences between the groups in the mean postoperative SAFE-Q scores for all subscales. All patients in the IM group returned to playing sports at their preinjury levels postoperatively. CONCLUSION: We found that skeletally immature patients with chronic lateral ankle instability had generally similar responses to arthroscopic lateral ankle as skeletally mature adult patients at minimally 2 years' follow-up with a high rate of successful return to sport. LEVEL OF EVIDENCE: Level III, retrospective case control study.

Angioleiomyoma of the right forefoot.

We describe a rare case of angioleiomyoma in the foot of a middle-aged man.

Bilateral and concomitant pathology' surgeries do not affect the outcomes of mini-open distal linear metatarsal osteotomy (Bosch osteotomy) with manipulation for hallux valgus deformity.

BACKGROUND: Bosch osteotomy for hallux valgus (HV) deformity has advantages of reduction both the operating time and surgical dissection, and may be performed bilaterally and with fewer complications than other surgical procedures as well as early weight-bearing. However, there are few reports on the effects of bilateral simultaneous surgery, simultaneous surgery on concomitant pathologies, and the preoperative HV angle on the postoperative results. The present assessed the factors that might affect the improvement in clinical outcomes following mini-open Bosch osteotomy with manipulation to treat HV deformity. METHODS: Seventy patients with 110 feet were included. They were divided into groups as follows: unilateral and bilateral simultaneous surgery groups, Bosch osteotomy alone and simultaneous surgeries for concomitant pathologies groups, and preoperative HV angle< 40° and ≥ 40° groups. Subjective clinical outcome scores using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and the HV and intermetatarsal first and second metatarsal (M1M2) angles according to the anteroposterior (A-P) view of the weighted foot X-ray were assessed preoperatively and at 12 months after surgery. RESULTS: The mean HV angle, M1M2 angle and all subscales of the SAFE-Q score showed significant improvement at 12 months after surgery, regardless of simultaneous bilateral surgery, simultaneous surgery for concomitant pathologies, or the preoperative HV angle. On comparing the groups, there were no significant differences in the HV angle at 12 months after surgery. Significant inferiority at 12 months after surgery was found in the intermetatarsal angle in the simultaneous surgery for concomitant pathologies group and in all subscales of the SAFE-Q score in the HV angle ≥ 40° group. CONCLUSION: Mini-open Bosch osteotomy with manipulation for HV deformity demonstrated good results in both radiological assessments and subjective clinical scores at 12 months after surgery, even for simultaneous bilateral surgery, simultaneous concomitant pathologies' surgery, and severe HV deformity. LEVEL OF EVIDENCE: Prognostic Level III, retrospective cohort study.

Hybrid Ankle Reconstruction of Lateral Ligaments.

Open anatomic reconstruction of the lateral ligament (AntiRoLL) of the ankle with a gracilis Y graft and the inside-out technique are commonly used and have evolved to minimally invasive surgery, including arthroscopic AntiRoLL (A-AntiRoLL) and percutaneous AntiRoLL procedures. A-AntiRoLL allows assessment and treatment of intra-articular pathologies of the ankle concurrently with stabilization. However, the A-AntiRoLL technique is technically demanding, especially in the process of calcaneofibular ligament reconstruction under subtalar arthroscopy. In contrast, the percutaneous AntiRoLL procedure is a simple concept that does not require the skill of an experienced arthroscopist but requires an extra skin incision to assess and treat intra-articular pathologies of the ankle. This study describes the application of a minimally invasive anatomic reconstruction technique-hybrid AntiRoLL-for chronic instability of the ankle that does not require advanced arthroscopic technique to assess and treat intra-articular pathology simultaneously.

Arthroscopic ankle lateral ligament repair alone versus arthroscopic ankle lateral ligament repair with reinforcement by inferior extensor retinaculum.

PURPOSE: This study aimed to compare the clinical outcomes and postoperative activities of arthroscopic ankle lateral ligament (ALL) repair alone with arthroscopic ALL repair and reinforcement by the inferior extensor retinaculum (IER) for chronic ankle instability (CAI). MATERIALS AND METHODS: All patients who underwent arthroscopic repair for CAI between 2017 and 2019 were evaluated. The Japanese Society for Surgery of the Foot (JSSF) scale and self-administered foot evaluation questionnaire (SAFE-Q), and duration between the surgery and walking without any support, jogging, and complete return to sports were evaluated and compared. The exclusion criteria were (1) follow-up period of < 1 year after surgery, (2) the presence of associated ankle lesions requiring treatment during the same operative procedure, including patients with subfibular ossicle bigger than 5 mm on radiographs, chondral or osteochondral defect, bony impingement, deltoid ligament tear, fibular tendon pathology, or posterior ankle impingement, and (3) patients who underwent revision surgery. RESULTS: We identified 126 patients who underwent surgery for CAI and subsequently excluded 36 patients on account of a short follow-up period (< 1 year), additional surgery, and previous surgery. The remaining 90 eligible patients included arthroscopic ALL repair alone (group A, n = 44) and arthroscopic ALL repair with reinforcement by the inferior extensor retinaculum (group G, n = 46) groups. There was no significant difference in the postoperative activities nor in the preoperative or postoperative JSSF scale and SAFE-Q between the two groups. However, significant differences were seen in the mean surgical time (15.5 ± 8.1 vs 20.1 ± 7.6, P = 0.013). CONCLUSION: This study showed no difference in clinical outcomes between the two groups. However, arthroscopic ALL repair with reinforcement by IER resulted in a longer surgical time than arthroscopic ALL repair alone. LEVEL OF EVIDENCE: Retrospective comparative study, level III.

Clinical outcomes of concurrent surgery with weight bearing after modified lasso-loop stitch arthroscopic ankle stabilization.

PURPOSE: To determine the effects of unilateral and bilateral ankle stabilization surgery with or without additional concurrent procedures for other pathologies on return to activity in patients who were allowed unrestricted weight bearing postoperatively. METHODS: Ninety-three athletes underwent 120 ankle stabilization surgeries including 27 that underwent bilateral simultaneous surgery using the all-inside arthroscopy-modified lasso-loop technique and were divided into two groups: arthroscopic ligament repair alone without concurrent procedures (group A) and with simultaneous procedures for other pathologies (group B). Group A was further subdivided into unilateral (group A1) and simultaneous bilateral ankle surgery (group A2), and group B into ankle stabilization surgery with simultaneous procedures not requiring weight bearing postoperatively (Group B1) and with concurrent procedures allowing weight bearing (Group B2). Return to activity postoperatively was assessed by recording the time to walk without any support, jog, and return to full athletic activities. Clinical outcomes were assessed preoperatively and 12 months postoperatively using a subjective clinical score. RESULTS: The average time between surgery and unsupported walk, jog, and return to full athletic activities was 1.6 ± 2.5, 16.9 ± 3.7, and 42.4 ± 19.3 days in group A, 17.2 ± 19.6, 34.5 ± 20.8, and 60.9 ± 22.8 days in group B, 1.7 ± 2.9, 16.1 ± 2.4, and 41.6 ± 18.2 days in group A1, 1.3 ± 0.6, 18.9 ± 5.5, and 44.6 ± 22.5 days in group A2, 25.3 ± 20.2, 43.3 ± 21.1, and 70.7 ± 23.1 days in group B1, and 4.8 ± 11.7, 20.7 ± 11.7, and 45.0 ± 13.7 days in group B2, respectively. These results indicate that the patients in group B2 showed a statistically significant faster time to return to activity than did those restricted from weight bearing. Differences in ankle stabilization alone between patients in groups A1 and A2 as well as groups B2 and A were not statistically significant. Clinical outcomes were similar for patients in groups B2 and A1 versus group A2. CONCLUSION: Time to return to activity and clinical outcomes after ankle stabilization surgery using the modified lasso-loop technique were negatively affected if simultaneous bilateral surgery or simultaneous concurrent procedures were added or if weight bearing was unrestricted. However, a delay in return to athletic activity was observed when ankle stabilization surgery was performed using the modified lasso-loop technique with concurrent procedures that require non-weight bearing postoperatively. LEVEL OF EVIDENCE: Level III.

Patellar fracture after total knee arthroplasty for rheumatoid arthritis.

Patellar fracture is one of the most challenging complications of total knee arthroplasty, but relatively, little is known about it in patients with rheumatoid arthritis. We retrospectively analyzed 329 total knee arthroplasties performed in 230 female patients with rheumatoid arthritis to identify the incidence and risk factors for postoperative patellar fractures. The mean age was 61.8 years, and the mean follow-up period was 6.2 years. Patellar resurfacing was performed in all cases. Five postoperative patellar fractures (1.51%) were identified, and a thin residual patellar thickness and the use of posterior-stabilizing components were identified as significant risk factors, although the number of fractures was small in both groups. There was also tendency of higher age and greater joint line change observed in patients with fracture compared with those without fracture.
