Cheilectomy With or Without Cryopreserved Amniotic Membrane-Umbilical Cord Allograft for Hallux Rigidus.

ABSTRACT:

Background

For hallux rigidus, dorsal cheilectomy remains a treatment option even with advances in interposition techniques and devices. Cheilectomy aims to alleviate dorsal impingement and improve pain and function as well as range of motion. Cryopreserved umbilical cord allograft, with properties to mitigate inflammation and scar formation, has theoretical benefit for improving outcomes following cheilectomy. In this first prospective randomized and blinded cheilectomy study reported, we aimed to compare outcomes between cheilectomy alone and cheilectomy with umbilical cord allograft.

Methods

Patients were randomized to cheilectomy alone (CA) or cheilectomy with cryopreserved umbilical cord (ie, amniotic membrane-umbilical cord [AM-UC]). Patients were evaluated with American Orthopaedic Foot & Ankle Society (AOFAS), Foot Function Index (FFI), and visual analog scale (VAS) pain outcomes collected preoperatively and at 6 months and 1 year postoperatively. In addition, radiographic range of motion data were collected using stress radiographs. Fifty-one patients (26 AM-UC, 25 CA) completed the study, with 5 bilateral surgeries in the AM-UC group and 2 in the CA group, totaling 31 and 27 feet, respectively.

Results

The AM-UC group had statistically significant improved AOFAS and FFI scores at 1 year compared with the CA group, but there was no difference at 6 months. There was no significant difference between groups for VAS-pain scores at any time point, but overall VAS-pain improved in both groups from preoperative values. There was no significant difference in range of motion (total arc) between groups and changes in range of motion (total arc) in both groups from preoperative to 1 year postoperative were small.

Conclusion

We present the results of the first randomized and blinded prospective study of cheilectomy surgery patients. When appropriately selected, cheilectomy remains a good option for patients with symptomatic hallux rigidus. Cryopreserved umbilical cord is a potential adjuvant to cheilectomy, with 1-year results showing improvements in functional outcome scores.

Project description:BackgroundHallux rigidus (HR) is a common source of forefoot pain and disability. For those who fail nonoperative treatment, minimally invasive dorsal cheilectomy (MIDC) is an increasingly popular alternative to the open approach with early positive results. Early failures may be due to lose bone debris from the MIDC as well as other intra-articular pathology that cannot be addressed with MIDC alone. Metatarsophalangeal (MTP) arthroscopy can be used in addition to MIDC to assess the joint after MIDC and address any intra-articular pathology while still maintaining the benefits of minimally invasive surgery. We report our clinical outcomes following MIDC combined with MTP arthroscopy.MethodsFrom November 2017 to July 2020, a retrospective analysis of all MIDC cheilectomies with MTP arthroscopy performed by the 2 senior authors was done. Wound complications, infections, revision rates, need for future surgery, conversion to fusion rates, pre- and postoperative range of motion, visual analog scale (VAS) scores, time to return to normal shoe, intraoperative arthroscopic findings, and operative time were collected. Follow-up average was 16.5 months (range 3-33 months).ResultsA total of 20 patients were included with an average follow-up of 16.5 months. The average VAS score improved from 7.05 preoperatively to 0.75 postoperatively (P < .05). Average range of motion in dorsiflexion increased from 32 to 48 degrees (P < .05) and plantarflexion increased from 15 to 19 degrees plantarflexion (P < .05). All patients were weightbearing as tolerated immediately after surgery in a postoperative shoe and transitioned to a regular shoe at average of 2.1 weeks. We had no wound infections, wound complications, revision surgeries, tendon injuries or nerve damage. One patient required conversion to a fusion 3 years after the index procedure. Average tourniquet time was 30.39 minutes (range 17-60 minutes) and total average operating room time was 59.7 minutes (range 40-87 minutes). On arthroscopic evaluation of the MTP joint after MIDC, 100% of patients had bone debris, 100% had synovitis, 10% had loose bodies, and 30% had large cartilage flaps within the joint.ConclusionMIDC and first MTP joint arthroscopy for treatment of hallux rigidus provide improved pain relief with minimal complications while still maintaining the benefits touted for minimally invasive operative procedures. Additionally, we have shown a high rate of intra-articular debris along with intra-articular pathology such as synovitis, loose chondral flaps, and loose bodies that exist after MIDC. This combined procedure has the potential for improving patient outcomes and may minimize risk of future revision surgeries compared with MIDC alone.Level of evidenceLevel IV, case series study.

Project description:BackgroundHallux rigidus is a common arthritic condition that has been addressed surgically with a range of techniques, from an isolated cheilectomy to first metatarsophalangeal (MTP) joint fusion. Recently, hemiarthroplasty with polyvinyl alcohol (PVA) hydrogel implant has been used as an alternative treatment to relieve pain while preserving motion of the first MTP joint. We retrospectively reviewed patient-reported outcome scores and clinical outcomes for patients treated for hallux rigidus with PVA hydrogel implant at an academic, multisurgeon center.MethodsA total of 103 patients who underwent first MTP hemiarthroplasty with PVA hydrogel implant between January 2017 and October 2018 were retrospectively reviewed (average, 26.2 months). Eight surgeons were represented. Baseline Patient-Reported Outcomes Measurement Information System (PROMIS) scores for the Physical Function, Pain Interference, Pain Intensity, Global Physical Health, Global Mental Health, and Depression domains were collected prospectively and compared with PROMIS scores collected at a minimum of 1 year postoperatively (average, 13.9 months). Seventy-three patients had both preoperative and postoperative scores. Ten of these patients had undergone a prior procedure of the first MTP, and 52 underwent concurrent Moberg osteotomy at the time of PVA hydrogel implantation.ResultsFor patients with baseline and postoperative PROMIS scores, significant pre- to postoperative improvement was detected for the Physical Function, Pain Interference, Pain Intensity, and Global Physical Health domains (P < .05). Patients who had undergone a prior procedure of the first MTP had significantly higher postoperative Pain Intensity scores compared with those who did not undergo a prior procedure. Patients undergoing concurrent Moberg osteotomy had significantly lower postoperative Pain Interference and Pain Intensity scores compared with those who did not undergo a Moberg. Two patients underwent revision procedures in the first 2 years postoperatively, one with revision hemiarthroplasty and one with conversion to arthrodesis.ConclusionOn average across our entire cohort, physical function and pain scores improved significantly pre- to postoperatively; however, postoperative pain scores were significantly higher for patients who had undergone a prior procedure of the first MTP and significantly lower for patients who underwent concurrent Moberg osteotomy. The implant displayed excellent survivorship in the first 2 years postoperatively, with only 2 revision procedures.Level of evidenceLevel III, comparative series.
