Evaluation of the ‘Spaarne soft tissue procedure’ as a treatment for recurrent patellar dislocations: a four-in-one technique

Purpose The ‘Spaarne soft tissue procedure’, is a 4-in-1 soft tissue procedure that treats recurrent patellar dislocations in the young and active population. The procedure has not yet described elsewhere. The purpose of this study is to analyse the redislocation rate and to evaluate the postoperative knee function and patient satisfaction. Methods Twenty-seven patients (34 knees) underwent the four-in-one SST-procedure. The 4-step technique required a minor change in 2010, including the use of a smaller strip of the patellar tendon for transposition. After a median follow-up of 10.4 years, the redislocation rate was evaluated as the primary outcome measure. Secondary outcome measures were functional outcome (IKDC, Kujala, Lysholm and Tegner activity scale) and Numeric Rating Scales for satisfaction and pain. Results Redislocation occurred in 8 cases (23.5%) and subluxation occurred in 13 cases (38.2%) post-surgery. A significant higher number of redislocations and subluxations were seen before 2010 (p = 0.04, p = 0.03). The median postoperative IKDC, Lysholm and Kujala scores for the total group were 54, 76 and 81 respectively. Pre- and postoperative Tegner activity scale were both level 3. Median NRS scores during rest, walking and sports were 1, 3 and 5 respectively. Satisfaction with the procedure was reported as ‘excellent’ or ‘good’ by 79% of the patients. Conclusion Despite the high overall redislocation rate and increased pain scores, the SST-procedure shows to be a safe procedure in patients with recurrent patellar dislocations based on the cases after 2010. Mid- and long-term results show moderate to good functional outcomes and satisfaction. Level of evidence Therapeutic retrospective cohort study, LEVEL III

Opioid Consumption Rate Following Foot and Ankle Surgery

Background: The rapid increase in the consumption of prescription opioids has become one of the leading medical, economic, and sociological burdens in North America. In the United States, orthopedic surgery is the fourth leading specialty in the number of opioids prescribed, and the largest among all operative specialties. There is insufficient evidence to guide surgeons about appropriate opioid prescription amounts after orthopedic foot and ankle (F&A) procedures. The aim of this study was to determine the opioid consumption rate after foot and ankle procedures and identify risk factors associated with higher use. Methods: A total of 535 patients who underwent foot and/or ankle surgery between August 2016 and March 2018 were included in the study. Each patient received a preoperative discussion about postoperative pain and expectations alongside a standardized handout. At the 2-week postoperative visit, the patients self-reported the amount of consumed opioids. Prescription details, number of opioid pills consumed, refill requests, pain-issue-related telephone calls, and additional physician/emergency department visits were documented. Patient demographics, comorbidities, use of regional anesthesia, hospitalization, surgery type/severity, and preoperative opioid use were collected. A total of 244 patients had a sufficiently complete data set for inclusion in the final cohort. Subjects had a mean age of 50 years (±16.3) and a body mass index (BMI) of 29 (±6.1). Sixty-six (27%) patients underwent a soft tissue procedure alone and 178 (73%) underwent a bony procedure. Results: On average, patients consumed 46.6% of the prescribed pills following a bony procedure and 42.4% after a soft tissue procedure, which resulted in a total of 4496 leftover pills. BMI, procedure type (bony vs soft tissue)/severity, and number of opioids prescribed were positively correlated with elevated consumption rates ( P = .008, P < .001, P < .001, P < .001, respectively). Conclusion: BMI, procedure type, and higher initial pill dispensation correlated with a larger number of consumed pills during the postoperative period. On average, patients took 42.4% of the prescribed opioid after soft tissue procedures and 46.6% after bony procedures, resulting in a significant number of unused pills. Future guidelines are necessary to improve postoperative pain management to prevent narcotic overprescription and minimize the downstream potential for unprescribed community opioid access. Level of Evidence: Level III, retrospective case series, analytic.

Opioid Consumption Rate After Foot and Ankle Surgery

Category: Opioid consumption rate and risk factors investigation after foot and ankle surgery Introduction/Purpose: The rapid increase in the consumption of prescription opioids has become one of the leading medical, economical, and sociological burdens in North America. In the United States, orthopedic surgery is the fourth leading specialty in the number of opioids prescribed, and the largest among surgical specialties. There is insufficient evidence to guide surgeons about appropriate opioid prescription amounts after orthopaedic foot and ankle (F&A) procedures. The aim of this study was to determine the opioid consumption rate after foot and ankle procedures, and to identify patient risk factors associated with higher use. Methods: A total of 535 patients who underwent a F&A surgery performed by one orthopedic surgeon from August 2016 to March 2018 were investigated. The study was approved by our IRB. Each patient received a preoperative discussion about postoperative pain and expectations alongside a standardized handout. At the two-week postoperative visit, the patient-reported amount of consumed opioids was recorded. Prescription details, the amount of opioids taken, refill requests, pain-issue related telephone calls, and additional MD/ED visits were also documented. Patient demographics and co-morbidities, use of regional anesthesia, postoperative inpatient hospitalization, surgery type and severity, and pre-operative opioid use were collected retrospectively. Total amounts of morphine equivalents were calculated and converted into oxycodone 5 mg pills for standardization. P-values of <0.05 were considered significant. Results: Two hundred forty-four patients with a mean age of 50 years (±16.3) and a BMI of 29 (±6.1) were included. Sixty-six (27%) patients underwent a soft tissue procedure alone and 178 (73%) underwent a bony procedure. 225 (92.2%) patients received regional block. Patients reported that they consumed only 51.2% of prescribed pills after a bony procedure and 42.4% after a soft tissue procedure, respectively, which resulted in a total of 4,496.2 left over pills that derived from this study amongst only 244 patients enrolled. There were 11 refill requests (4.5%), two (0.8%) additional MD/ED visits, and 19 (7.8%) telephone calls related to pain. BMI, procedure type, and number of opioids prescribed were positively correlated with the consumption rate (P =.002, P<.001, P<0.001, respectively). Conclusion: BMI, surgery type (bony vs. soft tissue), and a higher number of pills dispensed were correlated with higher use in the postoperative period. After an educative discussion on postoperative pain, patients took 42.4% of the prescribed opioid after soft tissue procedures and 51.2% after bony procedures, resulting in a significant number of unused pills now available to the community. Future guidelines are necessary to improve our postoperative pain management, but this study suggests that current amounts of dispensed pills after orthopaedic F&A procedures are approximately twice as high as necessary.

Treatment of Hallux Valgus Deformity Using a Suture Button Device: A Preliminary Report

Background: Hallux valgus (HV) is commonly treated with proximal or distal first metatarsal osteotomy. Despite good correction, these procedures have inherent risks such as malunion, nonunion, metatarsal shortening, loss of fixation, and avascular necrosis. Suture button fixation has been used for HV treatment. It avoids the risks of corrective osteotomies while maintaining reduction of the intermetatarsal angle (IMA). The goal of this study was to assess the radiographic and functional outcomes of patients undergoing HV correction with a distal soft tissue procedure and proximal suture button fixation. Methods: The authors retrospectively reviewed the charts and radiographs of 22 patients who had undergone HV correction using a distal soft tissue correction and proximal fixation with a miniature suture button device (Mini TightRope; Arthrex, Inc, Naples, FL). Mean follow-up was 27.7 months. The IMA, hallux valgus angle (HVA), and sesamoid station were measured on radiographs obtained preoperatively as well as in the immediate postoperative period and at final follow-up. Preoperative and postoperative Short Form-36 (SF-36) and Foot and Ankle Ability Measure (FAAM) scores were collected. Postoperative complications, and any additional operative procedures performed were also recorded. Results: The mean preoperative IMA and HVA were 16.9 and 32.6 degrees, respectively. The mean immediate postoperative IMA was 5.2 degrees ( P < .0001) and the mean HVA was 9.8 degrees ( P < .0001). At final follow-up, the mean IMA was 8.2 degrees ( P < .0001) and the mean HVA was 16.7 degrees ( P < .0001). The average change in HVA from preoperative to final follow-up was 16.0 degrees and the average change in IMA from preoperative to final follow-up was 8.6 degrees ( P < .0001). Sesamoid station assessment at the 2-week follow-up showed that 22 patients (100%) were in the normal position group; at final follow-up, 17 patients (77%) had normal position and 5 patients (23%) had displaced position. Although there were no clinically symptomatic recurrences, asymptomatic radiographic recurrence was noted in 5 patients (23%) who had a final HVA >20 degrees. All components of the FAAM and the SF-36 showed improvement from preoperative to final follow-up, although these changes were not statistically significant. Three patients experienced complications, including an intraoperative second metatarsal fracture, a postoperative second metatarsal stress fracture, and a postoperative deep vein thrombosis. Conclusion: The use of a distal soft tissue procedure in conjunction with proximal suture button fixation is a safe and effective procedure for treating symptomatic HV deformity. Our results show that this technique can correct the IMA, HVA, and sesamoid station without the need for osteotomy. Level of evidence: Level IV.

Treatment of Hallux Valgus Deformity Using a Suture Button Device

Category: Bunion Introduction/Purpose: Hallux valgus (HV) is commonly treated with proximal or distal first metatarsal osteotomies. Despite good correction, these procedures bear inherent risks such as malunion, nonunion, metatarsal shortening, loss of fixation, and avascular necrosis (AVN). Suture button fixation has been used as another form of HV treatment that avoids the use of corrective osteotomies and maintains reduction of the intermetatarsal angle (IMA). The goal of this study was to assess the radiographic and functional outcomes of patients undergoing HV correction with a distal soft tissue procedure and proximal suture button fixation. Methods: Twenty-two patients underwent HV correction utilizing a distal soft tissue correction and proximal fixation with the Mini TightRope (Arthrex, Inc, Naples, Florida) device. The IMA, hallux valgus angle (HVA), and sesamoid station were measured on radiographs obtained preoperatively as well as in the immediate post-operative period and at final follow-up. Preoperative and postoperative Short Form-36 (SF-36) and Foot and Ankle Ability Measure (FAAM) scores were collected. Postoperative Visual Analog Scale (VAS) scores, complications, and any additional surgical procedures performed were also recorded. Results: Mean follow-up was 27.7 months.The mean preoperative IMA and HVA were 16.9 and 32.6 degrees.The mean immediate postoperative IMA was 5.2 degrees(p<.0001)and the mean HVA was 9.8 degrees(p<.0001).At final follow-up, the mean IMA was 8.2 degrees(p<.0001)and the mean HVA was 16.7 degrees(p<.0001).Sesamoid station assessment at two-week follow-up showed that 22 patients(100%)were in the normal position group;at final follow-up,17 patients(77%)were in the normal position group and five patients(23%)were in the displacement group.Asymptomatic radiographic recurrence was noted in 5 patients(23%)who had a final HVA>20degrees.All components of the FAAM and SF-36 showed improvement from preoperative to final follow-up, although these changes were not statistically significant.The average final postoperative VAS was11.05.Of the 22 cases, three experienced complications, including an intra-operative second metatarsal fracture, a postoperative second metatarsal stress fracture, and a postoperative deep vein thrombosis(DVT). Conclusion: The use of a distal soft tissue procedure in conjunction with proximal suture button fixation is a safe and effective procedure for treating symptomatic HV deformity. Our results show that this technique can correct the IMA, HVA, and sesamoid station without the need for osteotomy and with minimal risk of complications.

Surgical Treatment of Mild to Severe Hallux Valgus Deformities With a Percutaneous Subcapital Osteotomy Combined With a Lateral Soft Tissue Procedure

Distal metatarsal (MT) osteotomies have been used in mild or moderate cases of hallux valgus (HV) and proximal MT osteotomy has been considered the treatment of choice for severe deformities. A distal osteotomy could achieve a greater degree of correction by the addition of a distal soft-tissue procedure and be used to treat also severe deformity. Limited evidence about the use of the percutaneous subcapital osteotomy (SCOT); a type of MT osteotomy, in combination of a soft tissue procedure, is available. We evaluated this procedure routinely used in our clinic. A total of 30 consecutive patients treated in our hospital from September 2012 to April 2015 with SCOT combined with lateral soft tissue release were included in this retrospective review. Outcomes assessed included radiological parameters: HV angle (HVA) and intermetatarsal angle (IMA), clinical evaluation using the American Orthopaedic Foot and Ankle Society (AOFAS) score, and complication rate. In 12 of the 30 patients included, the pathology was bilateral, comprising a total of 42 cases. The overall correction of the angles was statistically significant (P < .001), changing from a HVA of 28.2° and IMA of 13.5° preoperatively to 8.0° and 6.0° postoperatively, respectively. The cases were divided into mild-moderate (34/42) and severe (8/42). Both groups showed a statistically significant correction in the angles, 3 months after surgery (P < .001). The AOFAS score showed a median of 49 points (n = 24) preoperatively and of 95 points (n = 40) at the end of follow-up. The complication rate at end of follow-up was 19% (8/42). After a minimum follow-up of 1 year, our technique for HV correction results in a clinically relevant improvement of the radiological parameters and AOFAS score in mild to severe deformities. Combination with lateral release could be a meaningful surgical alternative for the treatment of severe cases to help decrease the risk of recurrence. Levels of Evidence: Level IV
