Joint Replacement Procedures

Hip
Replacement

Hip replacement removes damaged bone and cartilage, replacing them with precision-engineered components to eliminate pain and restore natural movement. Dr. Calendine specializes in the direct anterior approach hip replacement for reduced dislocation risk and accelerated return to daily activities

Knee
Replacement

Knee replacement resurfaces damaged bone and cartilage to relieve chronic arthritis joint pain and restore natural knee mobility. Dr. Calendine combines the muscle-sparing subvastus approach technique with Mako® robotic-assisted precision for faster recovery and improved long-term outcomes.

SubVastus Knee
Replacement

The subvastus approach accesses the knee joint beneath the vastus medialis (quadriceps) muscle, instead of cutting through it. This muscle-sparing technique delivers faster return of leg strength, reduced post-operative pain, and earlier independence during the critical first weeks of recovery.

Robotic Joint
Replacement

Mako® robotic-assisted surgery uses advanced CT-based 3D modeling of your unique anatomy to guide hip and knee implant placement with unmatched precision. Dr. Calendine performs robotic-assisted joint replacements for more accurate alignment and a faster, safer return to active living.

The BMI Cutoff Debate: What Hundreds of Thousands of Hip Replacements Reveal
Is there a BMI cutoff for hip replacement? New data from a national joint registry adds some clarity. Researchers analyzed hundreds of thousands of elective total hip replacements recorded in the German Arthroplasty Registry and tracked revision surgery and mortality into the mid-term.
Revision risk rose steadily with each obesity class. Most of that difference appeared within the first few months after surgery, and it was driven largely by periprosthetic joint infection. Revisions for mechanical reasons differed far less between groups. Cemented and cementless stem fixation performed similarly, and in patients with a BMI above 40, hospital caseload did not change revision risk.
Here is the part that matters most. The authors concluded that while obesity raises risk, the absolute risk of this potentially life-changing surgery may still be acceptable for many patients. Registry data from other countries show that patients with higher BMI gain comparable improvement in pain, function, and quality of life. That is why I do not believe a single number on a scale should decide who gets relief. Current evidence has not shown that delaying surgery for weight loss reliably lowers complication risk, and most patients asked to lose weight first are unable to reach that goal. What does matter is careful preparation: optimizing diabetes control, stopping nicotine use, and an honest discussion of individual risk.

Flexibility drives treatment. Assess the deformity both weight-bearing and seated, attempt passive correction at the PIPJ, and perform a Lachman test at the MTPJ. Dorsal displacement >2mm or 50% of the joint suggests plantar plate insufficiency, which should be addressed at the same time rather than left behind.
TENDON TRANSFER: FLEXIBLE DEFORMITY
Transferring FDL-FDB to the dorsal proximal phalanx converts deforming flexors into MTPJ plantarflexors during stance - restores balance lost when weak intrinsics are overpowered by stronger extrinsics.
RESECTION ARTHROPLASTY: SEMIRIGID TO RIGID, FLEXOR DRIVEN
Resecting the proximal phalangeal head shortens the flexor lever and suits elongated digits well. 
PIPJ ARTHRODESIS: STABILITY OPTION
Fusion turns the digit into a rigid lever arm, allowing the long and short flexors to augment the intrinsics at the MTPJ. It is preferred when deforming forces are significant or multiple digits are involved. Fixation continues to evolve.
OPEN OR MINIMALLY INVASIVE?
A retrospective comparison of 146 toes found no statistically significant difference between MIS and open correction in time to osseous union (~8-9 wks) or return to activity.
WHY IT MATTERS BEYOND THE TOE
Finite element modeling suggests hammertoe deformity blunts the windlass mechanism and reduces plantar fascia load sharing. That may be a driver of progressive deformity and, in diabetic patients, ulceration risk.
REDUCING FAILURE
Second digit corrections and deformities with a large transverse plane component fail more often. Correcting a concomitant first ray deformity has been associated with a nearly 50% reduction in hammertoe recurrence.

Olecranon Fracture Fixation Step by Step | Orthopedic Surgery
The point of your elbow is one of the most exposed bones in your body - with minimal padding. Your #olecranon is also where the triceps attaches. When it breaks, that muscle pulls the fragment up the arm and opens the fracture like a hinge. Because the break runs into the joint surface, most displaced olecranon fractures need surgery to restore the joint and get the elbow moving again.
For decades the standard repair was tension band wiring: two pins + a figure-of-eight wire that convert the triceps pull into compression across the fracture - fast and effective for simple transverse breaks. The tradeoff can be hardware that sits directly under the skin and often has to come out later. Pre-contoured plates offer an alternative. They sit on the back of the ulna (tension side) and wraps over the tip of the elbow. Proximal screws are angled into the dense bone at the base of the coronoid while stopping short of the joint surface. Many constructs add one long screw from the olecranon tip down the canal of the ulna (called the home run screw). The goal is solid purchase on both sides of the fracture, typically at least three screws above and three below.
Both techniques can deliver excellent function and the right choice depends on fracture pattern, bone quality, soft tissue condition, and patient goals.

🎈 A balloon for shoulder pain? It sounds unusual, but for the right patient it’s a real option. 
When a massive rotator cuff tear can’t be repaired, the humeral head can ride up and grind against the acromion, causing pain and limited motion. The InSpace subacromial balloon spacer is designed to restore that lost space.
How it’s done:
🔹 Through small arthroscopic incisions, the surgeon confirms the tear is irreparable and that the subscapularis is intact
🔹 The defect is measured to select a small, medium, or large balloon
🔹 The deflated balloon is inserted through a lateral portal and positioned above the humeral head
🔹 It’s filled with saline, briefly overinflated, then set to its final volume and sealed
The balloon takes only minutes to deploy, and many patients go home the same day.
Who may be a candidate:
✔️ Older, lower-demand patients
✔️ Massive, irreparable posterosuperior cuff tears
✔️ Preserved active shoulder motion
✔️ Intact subscapularis and no significant arthritis
Made of a biodegradable polymer, the balloon dissolves over about 12 months, yet many patients report relief that outlasts the device. Worth knowing: two major randomized trials reached different conclusions, so careful patient selection is essential. It’s one option among several, not a fit for every shoulder.

Cementless Knee Replacement: Is It Better Than Cement?
Your #kneereplacement will be attached to your bone in one of two ways, and many patients never hear that there was a choice. I use both. The decision is not a ranking. It is a fit.
Cemented fixation remains the gold standard. A powder and liquid are mixed into a paste, applied to the implant and the prepared bone, then pressed together. In about 15 minutes it hardens, bonded to metal on one side and bone on the other. Nothing has to heal or grow. The knee is stable from day one, and most knee replacements worldwide are still done this way. Cementless fixation uses no cement at all. The back of the implant is a porous, sponge-like metal surface pressed tightly into bone. It is stable immediately, so patients walk right away, and over roughly six to eight weeks the bone grows into that surface. The goal is living fixation that never lets go.
How do I decide? Mostly bone quality. Cementless requires bone strong enough to hold the implant on day one and healthy enough to grow into the metal. I review the CT scan, overall health, bone density, and x-rays. In surgery, I can feel how strong the bone is as the saw cuts. The bone gets the final vote. Why go cementless at all? Longevity. Cement is artificial and can slowly break down over many years. For younger, active patients, we want knees that last decades. Randomized trials show modern cementless designs performing alongside cemented knees in early and mid-term follow-up. Long-term data is still maturing. A cemented knee is not a lesser knee. It is the right choice for many patients.

Not long ago, a blood transfusion was a routine part of recovery for many hip and knee replacement patients. Today, it has become the exception. One inexpensive medication is a big part of why.
It is called tranexamic acid, or TXA.
Think of surgery as flipping two switches at once. The first tells your body to build clots and seal off bleeding. The second sends in a demolition crew that starts dismantling those clots too early. TXA does not build anything. It locks the demolition crew out. By occupying the lysine binding sites on plasminogen, it keeps the clot your body already formed stable while it does its job.
For patients, that means:
Less blood loss during and after surgery
A lower likelihood of needing a transfusion
Fewer transfusion-related risks that can slow recovery
For my fellow surgeons, the evidence spans randomized trials, meta-analyses, and large database studies in primary and revision arthroplasty. The open questions now center on optimal dose and route, not whether TXA works.
Safety is part of every decision. Large joint replacement studies have not shown an increased risk of clots in the legs or lungs, but a recent heart stent, a seizure disorder, or significant kidney disease calls for an individualized plan.

COMMON HIP & KNEE QUESTIONS

Frequently Asked Questions

How do I know if I need a hip or knee replacement?

Most patients who benefit from joint replacement share the same experience: persistent pain that limits daily life, stiffness that doesn’t improve with rest, and conservative treatments that are no longer working. If you are avoiding activities you used to enjoy — walking, climbing stairs, getting up from a chair — because of hip or knee pain, it may be time to speak with a specialist.

 

The decision is never made in a single appointment. Dr. Calendine reviews your X-rays, symptoms, and goals together to determine whether joint replacement is the right next step. There is no arbitrary age requirement. What matters most is how your pain affects your quality of life.

There is no minimum or maximum age for joint replacement. Dr. Calendine has performed successful replacements in patients in their 20s and in patients in their 80s and beyond. The determining factor is not age — it is the severity of your joint disease, your overall health, and how significantly your pain is affecting your life.

 

Modern implant materials and surgical techniques — including robotic-assisted surgery with the Stryker Mako system — are specifically designed to meet the demands of active lifestyles and carry excellent long-term performance data.

Robotic-assisted joint replacement uses the Stryker Mako system to enhance the precision of implant positioning during surgery. Before your operation, a CT scan creates a three-dimensional model of your joint anatomy. On the day of surgery, the robotic arm works with Dr. Calendine to execute pre-planned implant placement with a level of accuracy that is difficult to achieve with traditional manual techniques alone.

 

The result is an implant positioned to match your unique anatomy — with the goal of more natural movement, better longevity, and a more predictable recovery. Dr. Calendine is one of the highest-volume Mako surgeons in Middle Tennessee.

The subvastus approach is a muscle-sparing surgical technique that Dr. Calendine offers for total knee replacement. In a standard knee replacement, part of the quadriceps tendon is divided to access the joint. In the subvastus approach, the surgeon passes underneath the quadriceps muscle rather than through it — leaving the muscle entirely intact.

 

For appropriate candidates, this approach can mean faster recovery of quad strength, more comfortable early recovery, and outcomes patients consistently describe as feeling more natural in the first weeks after surgery.

Recovery timelines vary by procedure and patient, but modern techniques — especially the anterior approach for hip replacement and the subvastus approach for knee replacement — are designed to move patients forward faster than older methods.

 

For hip replacement: most patients walk with a walker on the day of surgery and are driving by four to six weeks. For knee replacement: patients typically regain full daily function within six to eight weeks. By three months, most patients are doing virtually everything they did before surgery. Full recovery continues through six months and beyond.

Both procedures relieve arthritis pain by replacing a damaged joint with a precision-engineered implant — but the anatomy, surgical approach, and recovery are distinct.

 

In hip replacement, the damaged ball and socket are replaced. Dr. Calendine uses the anterior approach for most hip replacements, which avoids cutting through the gluteal muscles and typically results in faster recovery. In knee replacement, the worn joint surfaces are resurfaced with metal and plastic components. Dr. Calendine performs total knee replacement using the subvastus muscle-sparing technique combined with Mako robotic precision.
