Wayne B. Leadbetter
The Pathophysiology of Patellofemoral Arthritis 269
Ronald P. Grelsamer, David Dejour, and Jason Gould
Faced with a patient suffering from patellofemoral arthritis, the surgeon must determine
the pathophysiology of the condition, because different causes demand ditlerent
treatments. Possible causes include malalignment, patellofemoral dysplasia, patellole-
moral instability, patellofemoral trauma, obesity, osteoarthritis, inflamm.itory arthritis,
and a genetic predisposition. Arthritis secondary to malalignment, dvsplasia, instability,
or trauma is less likely than arthritis secondary to the other causes to progress to
femorotibial arthritis.
Prescribing Quality Patellofemoral Rehabilitation
Before Advocating Operative Care 275
Anil Bhave and Erin Baker
In this article we discuss causes of patellofemoral dysfunction, the treatment algorithm
of nonsurgical therapy modalities, and what constitutes a quality rehabilitation protocol
for a patient with patellofemoral dysfunction.
Patellofemoral Syndrome a Paradigm for Current Surgical Strategies 287
Robert A. Teitge
The literature regarding suggested treatments for patellofemoral problems is often
conflicting and confusing. In this discussion I present the approach I take in evaluating and
considering surgery for patients with any of a wide variety of anterior knee pain problems
It has been useful to concentrate on the biomechanics—the mcvhanical ionsei|tience to
each tissue affected by any surgical change. In the proposed paradigm, it is assumed th.it
pain is the result of an abnormal load—related either to tension or compression ¦¦¦ being
applied to each tissue in question. The challenge is to understand how ,ind win th.it
abnormal load was generated. It is essential to make an independent assessment ol the
condition of the lower limb skeleton, the patellofemoral ligaments, ,ind the trot hle.ir and
patellar articular cartilage in each patient. While only a long book can address this suh|ect
in detail, this discussion provides a guide for formulating an analysis of the kev issues
when planning the operative treatment of patellofemoral pain and dysfunction.

The Management of Recurrent Patellar Dislocation 313
Jack Andrish
Acute and chronic trauma, chronic abnormal joint loading conditions, and hemarthroses
have been implicated in the development of degenerative joint disease. Patellar
instability with acute and recurrent patellar dislocation provides all of these ingredients.
This article describes an approach to the treatment of recurrent patellar instability that
considers the unique features and expectations of the patient rather than using a generic
algorithm.
Autologous Chondrocyte Implantation and Anteromedialization
in the Treatment of Patellofemoral Chondrosis 329
Jack Farr, II
Patellofemoral articular cartilage lesions are challenging to treat. While treatment with
tibial tuberosity anteromedialization (AMZ) is effective for isolated distal lateral patellar
lesions, other patellar or trochlear lesions have suboptimal outcomes with AMZ.
Historically, when autologous cultured chondroctye implantation (ACI) was used at the
patellofemoral compartment without optimizing the contact areas, the results were poor.
In recent years, the combination of AMZ and ACI has yielded overall outcomes superior
to either technique used in isolation for large patellar and trochlear chondral lesions.
Focal Anatomic Patellofemoral Inlay Resurfacing: Theoretic Basis,
Surgical Technique, and Case Reports 337
Philip A. Davidson and Dennis Rivenburgh
Prosthetic patellofemoral inlay resurfacing is a novel treatment concept for degenerative
and focal arthrosis of the patellofemoral joint. The theoretic basis of this type of
arthroplasty entails recreating ambient anatomy based upon intraoperative topographic
mapping. The implant is intrinsically stable by virtue of the inset position relative to the
surrounding joint surface. Articular resurfacing, rather than traditional replacement
arthroplasty, represents an extension of the concepts of biologic joint restoration. Early
results have shown great efficacy. This surgery may be appropriate for a wide variety of
indications, including younger patients and those with focal patellofemoral disease
concurrent with morphologic or alignment abnormalities.
Patellofemoral Arthroplasty: The Impact of Design on Outcomes 347
Jess H. Lonner
The results of patellofemoral arthroplasty have been improved over the three decades that
the procedure has been used for the treatment of patellofemoral arthritis. Specifically,
there has been a reduction in the incidence of patellofemoral-related problems, such as
patellar maltracking and catching, after patellofemoral arthroplasty. While these
problems were often attributed to errors in surgical technique or component malposition,
it is likely that many were related to flawed trochlear component designs. Contemporary
patellofemoral arthroplasties have a reduced incidence of the problems related to patellar
maltracking that typically plagued earlier generation designs. Further study will likely
prove contemporary patellofemoral arthroplasty to be an effective treatment for the
management of isolated patellofemoral arthritis, with predictable outcomes and a low
incidence of complications.
Patellofemoral Arthroplasty with a Customized Trochlear Prosthesis 355
Domenick J. Sisto and Vineet K. Sarin
Successful patellofemoral arthroplasty depends on appropriate patient selection, proper
prosthesis design, and correct surgical technique. Clinical results using off-the-shelf
vi CONTENTS
patellofemoral prostheses have reported mixed results primarily because of an inability
to address these important characteristics adequately. This article reviews the design
rationale, excellent clinical history, and straightforward surgical technique of a unique
approach to patellofemoral arthroplasty that incorporates a customized trochlear
prosthesis designed to fit the individual patient s patellofemoral groove. Clinical results
using this customized approach demonstrate that it is a safe and effective treatment
option for patients who have isolated patellofemoral arthritis.
Patellofemoral Arthroplasty in the Treatment of Patellofemoral Arthritis:
Rationale and Outcomes in Younger Patients 363
Wayne B. Leadbetter
Patellofemoral degenerative disease encompasses a spectrum of articular wear from
severe chondrosis to advanced arthrosis. The rationale and timing for many operative
approaches currently advocated for the relief of symptomatic patellofemoral degener¬
ation can be the subject of intense surgical debate in any one patient. Unfortunately, the
limited efficacy of many commonly advocated operative procedures has left a legacy of
patellofemoral disability in many younger individuals. While total knee arthroplasty has
an established role in the treatment of advanced patellofemoral arthritis in the older
patient (age 60 years), the performance of what some have called a knee joint
amputation in younger patients (age 45 years) remains controversial and less
acceptable to patients. The Avon patellofemoral prosthesis is a second-generation knee
joint-conserving device that has consistently achieved good to excellent results in both
the primary treatment and salvage of patellofemoral degenerative disease in younger
patients. In addition, patellofemoral arthroplasty has demonstrated success as a unique
functional, tibial-femoral joint-conserving solution in a variety of other patellofemoral
extensor mechanism problems.
Results of Total Knee Replacement for Isolated Patellofemoral Arthritis:
When Not to Perform a Patellofemoral Arthroplasty 381
Ronald E. Delanois, Mike S. McGrath, Slif D. Ulrich, David R. Marker,
Thorsten M. Seyler, Peter M. Bonutti, and Michael A. Mont
Many procedures have been used to treat advanced isolated patellofemoral arthritis,
with varying results. Patellofemoral arthroplasty (PFA) is a bone-conserving procedure
that has shown short-term success but has relatively high revision rates. Total knee
arthroplasty (TKA) has been recommended for treatment of this disease in patients who
are older than 60 years of age. Recent literature indicates that PFA is most successful in
patients who have isolated patellofemoral arthritis secondary to trochlear dysplasia or
patellar fracture and in patients who are younger than 60 years; TKA is recommended
for older patients who have primary or idiopathic isolated patellofemoral arthritis.
