The Importance of the Medial Column in Progressive Collapsing Foot Deformity
Adult acquired flatfoot deformity is a complex pathologic condition that requires considerate and thoughtful surgical solutions. Medial column procedures are often supplemented by a medializing calcaneal osteotomy and/or a lateral column lengthening because of the complex nature of progressive collapsing foot deformity and its resultant peritalar instability. Other osteotomies and fusions include a Cotton osteotomy and first tarsometatarsal fusion. (Source: Foot and Ankle Clinics)

Progressive Collapsing Foot Deformity: Should We Be Staging It Differently?
This article cursorily reviews the history of classification systems for pathologic flatfoot deformity in the adult and also critically reviews the recent introduction of a classification system intended to improve on the deficiencies of prior systems. The article concludes by offering suggestions for further work in evolving even more utilitarian systems for the staging and treatment of adult flatfoot disorder. (Source: Foot and Ankle Clinics)

Flexible Progressive Collapsing Foot Deformity
Over the last two  decades there is a growing interest in the adult literature for subtalar joint arthroereisis. Parallel to this interest, there have been improvements in the design and biomechanics of the implant, although the main indication of subtalar joint arthroereisis in adults is not clear. Most studies sho w significant improvement in postoperative clinical scores and visual analog scores. Sinus tarsi pain, being the most common complication, is the main determinant of clinical satisfaction. This review focuses on the role and complications of subtalar joint arthroereisis in the adult population. (Source: Foot and Ankle Clinics)

Surgical Management of Musculotendinous Balance in the Progressive Collapsing Foot Deformity
Surgical treatment of progressive collapsing foot deformity (PCFD) relies on understanding the dynamic and deforming musculotendinous structures that contribute to hindfoot valgus, forefoot abduction, forefoot varus, and collapse or hypermobility of the medial column. Equinus commonly is seen in PCFD and consideration should be given to isolated gastrocnemius or Achilles lengthening. Although transfer of the flexor digitorum longus tendon is performed in PCFD attributed to dysfunction and pathology of the posterior tibialis tendon (PTT), retention of PTT is an area for further research. The peroneus brevis, which contribut...

Is Arthrodesis Sufficient in the Setting of Complex, Severe and Rigid Progressive Collapsing Foot Deformities?
Arthrodesis of the hindfoot is typically used for the correction of severe and arthritic progressive collapsing foot deformity. Concomitant bony or soft tissue procedures may be helpful in patients with congenital abnormalities including the ball-and-socket ankle or congenital vertical talus. Dysplasia of the hindfoot bones may be more common than previously recognized, and corrective procedures or alterations in technique may need to be performed during hindfoot arthrodesis to account for bony deformity. Intraarticular osteotomies, extraarticular osteotomies, tendon lengthening, and tendon transfer procedures may be used ...

Progressive Collapsing Foot Deformity. Is There Really a Johnson and Strom Stage I?
Johnson and Strom stage I posterior tibialis tendon dysfunction presents with pain and swelling but preserved function and no deformity. Diagnosis is clinical. Pathomechanics explains the overloading of the tendon that may be worsened by a tight gastrocnemius, but systemic inflammatory disease may also be responsible for a stage I condition. Medial heel wedged orthoses are effective in most patients. Surgery usually consists of an open/endoscopic tenosynovectomy. In cases of complete tendon rupture, flexor digitorum longus tendon transfer may be considered. Stage I patients with a higher risk of progression —inflammatory...

I Am Afraid of Lateral Column Lengthening. Should I Be?
Lateral column lengthening has long been used in conjunction with other soft tissue and bony procedures to correct the midforefoot abduction seen in class B progressive collapsing foot deformity. The effectiveness of this osteotomy to restore the physiologic shape of the foot has been used by foot and ankle surgeons around the world to provide functional improvement for patients suffering from this disease. The overall low complication rates, low nonunion rates, and improved radiographic and functional outcomes provided by lateral column lengthening make this a valuable option for the treatment of class B progressive colla...

Tendon Transfer versus Allograft Reconstruction in Progressive Collapsing Foot Deformity
The posterior tibial tendon (PTT) is the principal dynamic stabilizer of the medial longitudinal arch of the foot. The basic goal of surgically reconstructing PCFD is to restore the foot's medial longitudinal arch, often through a combination of bony and soft tissue procedures. While the FDL transfer has long been the gold standard for reconstruction, allograft reconstruction of the PTT has recently been increasing in popularity. (Source: Foot and Ankle Clinics)

Big Shoes to Fill in Foot and Ankle Clinics of North America, but They are Definitely Pointed in the Right Direction
When I was asked by Dr Myerson to serve as the Guest Editor for this issue of Foot and Ankle Clinics of North America back in mid-2019, I was ecstatic! I consider it a huge honor and responsibility to write high-quality review articles for this prestigious journal. As one can imagine, serving as guest editor of an issue on Progressive Collapsing Foot Deformity was more than I could hope for. I enjoyed every step of the process, starting with considering the essential subjects to be covered, discussing possible leading titles, and selecting the right people to author the articles.
