Mystery Knee Pain Not In “Head”, But In “Rear End”

Written by admin on March 18, 2013 – 2:59 pm -

“Patellofemoral pain syndrome (PFPS) is one of the most common presentations to sports medicine practitioners. In a large study of 2519 presentations to a sports medicine clinic, 5.4% were diagnosed with PFPS, accounting for 25% of all knee injury presentations.”

“There is growing evidence to support the association of gluteal muscle strength deficits in individuals with patellofemoral pain syndrome (PFPS) and the effectiveness of gluteal strengthening when treating PFPS. ”

…”effect of repeat injections of hyaluronic acid unclear. May not halt progression of OA nor delay knee replacement”…

“Osteoarthritis (OA) is characterized by degeneration of cartilage and its underlying bone within a joint as well as bony overgrowth, which ultimately lead to pain and joint stiffness. Most commonly affected joints are the knees, hips, and joints in the hands and spine. OA of the weight bearing joints (e.g. knee and hip) typically have the most clinical significance. The causes of OA are presumed to be related to mechanical and molecular events in the joint (http://www.cdc.gov/arthritis/basics/osteoarthritis.htm).

OA usually begins after the age of 40. OA affects 13.9% of adults aged 25 and older and 33.6% of those aged 65 and over (http://www.cdc.gov/arthritis/basics/osteoarthritis.htm). Among those affected, approximately one quarter of them are severely disabled. [3] Osteoarthritis is the leading cause of mobility disabilities such as difficulty walking or climbing up stairs. OA of the knee is one of five leading causes of disability among non-institutionalized adults. [4]

Knee OA is the most prevalent, followed by hip OA. Both knee and hip OA result in joint pain and stiffness which can ultimately interfere with function and restrict activities of daily living [5].

There is no cure for OA. In addition, there are currently no known therapies that can prevent progression of OA. Treatment of OA typically focuses on minimizing pain and swelling, reducing disability and improving quality of life.
Treatment typically starts with non-pharmacologic therapy approaches including exercise programs, weight loss, patient education and shoe insoles. [6] Non-pharmacologic approaches are typically tried before medications are started.

Pharmacologic treatment is typically the next step and focuses on relief of pain. Pharmacologic therapy typically includes acetominophen, nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase (COX-2) inhibitors and opiates. Each of these medications can be beneficial in some patients and each is associated with characteristic side effects. Given that the patient population is typically an older one, often with other comorbid conditions, the side effects associated with long term use of some of the OA medications can be particularly problematic.

Intra-articular glucocorticoid injections are another potential component of OA treatment….”

New Article: Fits Like a Glove

Customization has become de rigueur in almost every facet of modern life. Very few things, today, are “one size fits all.” The same is true for knee replacement (TKA or total knee arthroplasty).

For years manufacturers and surgeons have tried in vain, to personalize the fit and match of joint replacement prosthesis to the exact physiology and mechanics of each individual patient. All too often the end result of these labors represents a triumph of marketing over science—the so-called gender-specific knee is a classic example. Recently much has been made of computer assisted surgery. We have all read about and seen television images of large computers in the operating suite directing a “robot” to make “incisions and cuts.” These purport to improve accuracy and imply better performance and longevity of the implant. Unfortunately, and not surprisingly, the results have yet to meet the expectations of such promising technology. As computer assisted surgery is dependent upon collection of independent patient data obtained in the Operating Room, the results are necessarily limited by the quality of the collection method. The accuracy of the data varies greatly by surgeon and by individual patient– “Garbage in=Garbage out.”

As the data entered into the computer is obtained via relatively inaccurate means, the results are little improved compared to earlier techniques employed by surgeons for decades. Even more, this method requires significantly increased OR time.

“Ok . . . so, computer assisted surgery offers no advantage in performance but adds cost and time. So far, doc, you are not selling me on this concept. What gives?”

It is important to understand that while the results engendered by the implementation of computer assisted surgery have been mixed, at best, the concept is excellent—Personalization of the surgical procedure to meet the exact biomechanical needs of the patient has been the Holy Grail of joint replacement surgeons. Traditionally, TKA is performed utilizing cutting blocks, “jigs,” alignment rods, plumb lines, etc.; not dissimilar from standard cabinetry techniques. These have provided good to excellent results for decades. Unfortunately these methods are limited by individual patient factors (body weight, joint alignment, range of motion) that make it difficult, time consuming, and sometimes impossible to restore the appropriate anatomic alignment for any given patient.

Many manufacturers, in response to this dilemma, now offer a solution to this problem.  In particular, I find the Biomet Signature system to provide the most intuitive and elegant approach.  This is the system that I use for all TKA that I perform. 

Signature is a software-based system that allows the  measurement and much of the technical work to be completed on computer BEFORE the patient enters the OR.  Imagine that!  Doing one’s homework, before the test– What a novel idea! 

Not surprisingly, the results are just as predictable (study before attending class, Ace the test).  The concept and execution are rather simple.  MRI images are obtained of the patient’s Hip, Knee and Ankle.  This information is used to determine the limb alignment and to create a 3-D model of the knee.  This then allows the surgeon to essentially “perform” the surgery on the computer to correct the limb alignment to normal.  Once this data is finalized, a model of the knee is created and precision cutting instruments are manufactured that are unique to each patient.  These models and instruments are then used by the surgeon to perform the procedure according to plan.  Restoration of the patient’s natural limb alignment, improved fit and range of motion are the typical result.Utilizing this technique, the procedure can be performed more quickly and with less blood loss when compared to the traditional method of knee replacement.  Patients normally report less pain, improved range of motion and sometimes a shorter duration of hospitalization and outpatient rehab. 

Today, for the first time in history, with modern surgical and computer assisted techniques you can finally have a knee replacement that “fits like a glove”
