HOW NORMAL KNEE WORKS ?
The knee is the largest joint in the body, and one of the most easily injured. It is made up of the lower end of the thigh bone(femur), the upper end of the shin bone (tibia), and the knee cap (patella), which slides in a groove on the end of the femur. Four bands of tissue, the anterior and posterior cruciate ligaments, and the medial and lateral collateral ligaments connect the femur and the tibia and provide joint stability. The surfaces where the femur, tibia and patella touch are covered with articular cartilage, a smooth substance that cushions the bones and enables them to glide freely. Semicircular rings of tough fibrous-cartilage tissue called the lateral and medial menisci act as shock absorbers and stabilizers.
WHAT IS THE ROLE OF ACL ?
ACL along with other ligaments of the knee joint and meniscus provides stability to the knee joint.
WHAT IS LIGAMENT RECONSTRUCTION ( ACL ) ?
Ligament reconstruction involves replacing the torn ligament with a tendon (graft) from your knee and fixing the graft in place with screws. This procedure is performed with the use of the arthroscope. The anterior cruciate ligament (ACL) is the most common ligament requiring reconstruction procedures. The torn ligament is excised arthroscopically and new ligament is prepared by ligament grafts taken from your own body. Bony tunnels are prepared in femur and tibia using specialized instruments through which the new ligament is passed and fixed with special screws. This procedure requires relative rest or leave from your work or studies for about 2-3 weeks after which you will be allowed normal day to day activities.
WHEN CAN THE PATIENT BE AMBULATED AFTER SURGERY ?
The patient can walk from the same evening of the surgery. Initially the patient is advised to walk with a brace and a walking cane. Strengthening and range of motion exercises for the knee are started from the next day. The patient is discharged from the hospital 2nd or 3rd day after surgery. The patient can walk without support by 10-14 days depending on muscle strengthening. Slow Jogging and other strenuous activities are permitted after 3 months and the patient can return to active sports only 8-9 months after surgery.

Seminar recent advances reverse shoulder arthroplasty
This document discusses reconstructive surgery of the glenohumeral joint, including reverse total shoulder arthroplasty. It provides an anatomical overview of the glenohumeral joint and describes the indications, surgical procedure, components, and complications of reverse total shoulder arthroplasty. Reverse total shoulder arthroplasty involves replacing the normal ball and socket articulation with a convex glenoid component and concave humeral cup to improve function and range of motion, especially for conditions involving rotator cuff dysfunction.
Evolution of Total Hip Replacement
This document discusses the history and evolution of total hip arthroplasty (THA) and hip replacement component designs. It outlines key developments from the late 19th century experiments with ivory and tissue replacements, to modern THA pioneered by Professor Charnley in the 1960s using bone cement and low friction materials. Current designs aim to restore normal hip biomechanics and include cemented or cementless femoral and acetabular components with various fixation methods and bearing surfaces to reduce wear. Future advances focus on minimally invasive techniques, computer navigation, and developing more durable and compliant bearing materials to improve implant longevity.
Templating of total hip replacement (THR)
Templating implants prior to total hip replacement (THR) surgery is important to ensure precision, soft tissue balance, and reduced complications. It requires standard radiographic views to assess bone quality, structural integrity, and limb length discrepancy. The sequence is to first template the acetabulum considering factors like inclination, version and bone coverage, then template the femur assessing offsets, stem size and fit. Choosing the appropriate acetabular and femoral components also considers factors like fixation type, material, and design features to optimize function and reduce issues like impingement, wear and dislocation.
Femoro-acetabular impingement syndrome
This document discusses femoro-acetabular impingement (FAI), which occurs when there is reduced range of motion of the hip due to uneven surfaces of the femoral head or acetabulum. It can be caused by congenital or acquired factors. FAI is classified into cam, pincer, and mixed types. Cam FAI involves a bump on the femoral head-neck junction, while pincer FAI is due to overcoverage of the acetabulum. Clinical features include groin pain exacerbated by activity. Imaging can identify bone abnormalities, and treatments range from activity modification to surgical procedures like arthroscopy or osteotomy.
shoulder arthroplasty
This document provides an overview of classical shoulder arthroplasty versus reverse shoulder arthroplasty. It discusses the history, anatomy, biomechanics, prosthesis designs, surgical approaches, complications, and outcomes of both procedures. Key points include that total shoulder arthroplasty generally provides better outcomes than hemiarthroplasty, especially long-term. Reverse shoulder arthroplasty is primarily used for nonfunctional rotator cuff tears, while classical arthroplasty requires an intact rotator cuff. Complications can occur years after surgery and include loosening, infection, and fractures.
Old unreduced dislocations
Old unreduced dislocations of the hip and shoulder can be caused by trauma, neglect, or comorbid injuries that distract from the dislocation. Treatment depends on factors like time since injury, bone integrity, and viability of the femoral head. Options include closed or open reduction, osteotomy, arthroplasty, or no treatment. Open reduction may be necessary to address bone defects, fibrosis, and instability.
Templating X-rays in THR
This document discusses the concept and methodology of templating for total hip replacement surgery. It begins by defining templating as a radiographic planning process using templates to estimate implant positioning and identify difficult cases. It then describes the goals of templating as predicting implant size and position to restore hip biomechanics. The document outlines the steps of templating, including identifying anatomical landmarks and mechanical references on radiographs. It emphasizes the importance of restoring leg length, offset, and the center of rotation.
KNEE INJURIES
1. The document discusses knee dislocations, which occur when there is an abnormal relationship between the knee bones during range of motion.
2. Knee dislocations are serious injuries that can impair physical activity and require evaluation of ligament injuries, fractures, arterial injuries and nerve injuries.
3. Evaluation involves physical examination of the knee ligaments using stress tests like anterior drawer, Lachman's and varus/valgus tests as well as imaging like x-rays and stress radiographs. Priority is given to evaluating for vascular injuries before and after reduction.
Pffd
Proximal femoral focal deficiency (PFFD) is a birth defect where the femur is shorter than normal with discontinuity between the femoral neck and shaft. It can be associated with other anomalies. The cause is unknown but theories involve neural crest cell injury or chondrocyte proliferation issues. Treatment depends on the predicted femoral length at maturity and pelvic-femoral stability, with options including limb lengthening, amputation with prosthesis, and rotationplasty or arthrodesis. The goals are to address limb length inequality, joint instability, and functional deficits.
Titanium elastic nail
The document discusses the Titanium Elastic Nail (TEN) technique for treating fractures in children. TEN uses two elastic nails inserted into the bone's metaphysis that provide flexural, axial, translational, and rotational stability. TEN is primarily used for diaphyseal and metaphyseal fractures in children, depending on their age and type of fracture, such as transverse or spiral fractures. Contraindications include intraarticular fractures and complex femoral fractures in older, overweight children.
Primary total knee arthroplasty
Primary Total Knee Arthroplasty has evolved since the 19th century with various prosthetic designs introduced over time. Prosthetic design considerations include femoral rollback, modularity, constraint, and whether to retain or sacrifice the cruciate ligaments. Radiographs are important for preoperative planning to assess alignment and bone defects. Surgical goals include restoring mechanical alignment, joint line, balanced soft tissues, and normal patellofemoral tracking. Key steps include femoral and tibial cuts, balancing the knee in flexion and extension, and addressing any flexion contractures or deformities. Complications can include nerve palsies, vascular issues, stiffness, infections, and loosening. With careful patient selection, planning and technique, total knee
Cementless acetabular cups
This document summarizes the history and evolution of cementless acetabular cups used in total hip replacements. It discusses the various materials used, cup shapes, surface coatings, liner designs, fixation methods, and long-term survivorship outcomes. Specifically, it traces the development from early threaded cups in the 1960s-1970s, to hemispherical cups in the 1980s, to improvements in polyethylene liners and modularity in the 1990s-2000s that have led to 10-20 year survivorship rates of 85-96% for current cementless cup designs, comparable to outcomes for cemented cups. Press-fit fixation is emphasized as the primary method of stabilization, with supplemental screws as needed.
Reverse Shoulder Arthroplasty
Reverse shoulder arthroplasty is a procedure used to treat shoulder arthritis and rotator cuff tears. It works by reversing the natural ball-and-socket anatomy of the shoulder joint. Early results showed improved shoulder function and pain relief. However, complications can include scapular notching, instability, infection, and loosening. Modifications to implant design, including increased prosthetic overhang, have helped reduce scapular notching. While reverse shoulder arthroplasty can improve shoulder function in patients with rotator cuff dysfunction, long-term outcomes remain variable and reoperations are sometimes required to address complications.
Pes planus and pes valgus
This document discusses several foot conditions including pes planus (flat foot), pes valgus, flexible flat foot, congenital vertical talus, tarsal coalition, and posterior tibial tendon disorder. It provides details on the anatomy of the foot arches, clinical features, causes, treatments and imaging findings for each condition. Common causes of flat foot discussed include flexible flat foot in children, congenital vertical talus, tarsal coalition, and posterior tibial tendon insufficiency in adults. Imaging can help evaluate the degree of deformity and guide treatment, which may include orthotics, casting, or surgery depending on the condition.

It involves replacing worn bone and cartilage in the hip joint with prosthetic components including a femoral stem, femoral head, and acetabulum cup. A total hip replacement is commonly performed for conditions like osteoarthritis, rheumatoid arthritis, and avascular necrosis. The design of the total hip replacement system aims to provide a custom fit with rounded surfaces for maximum load distribution and a substantial outer spherical surface on the femoral head for a wide range of motion.

The femoral head and acetabular cup are also modeled, with the cup including grooves to enhance cement fixation. Dimensions and assembly views of the stem, head, and cup are presented. The design is intended to replace diseased bone and cartilage in total hip replacement surgery.
total hip replacement discussion
This document provides an overview of hip anatomy, total hip replacement procedures, and pre-operative assessment for total hip replacement. It discusses the components of the hip joint, how a total hip replacement replaces arthritic parts of the joint with prosthetic components, and factors assessed pre-operatively such as range of motion, muscle atrophy, and x-ray findings. Indications and contraindications for total hip replacement are also summarized.
ORTHOPEDIC (HIP BONE)
This document provides an overview of hip replacement surgery. It discusses the anatomy of the hip joint and common indications for replacement surgery, including osteoarthritis and fractures. The surgery involves removing damaged bone and cartilage and replacing them with prosthetic components, including a metal femoral stem implanted into the femur and a plastic spacer inserted between the new ball and socket. Risks associated with the surgery include bleeding, infection, and implant loosening. The document also briefly describes hemiarthroplasty, where only half of the hip joint is replaced.
Total Hip Replacement (1)
Total hip replacement involves replacing the ball and socket joints of the hip with prosthetic components. The procedure involves removing the damaged femoral head and reaming the acetabulum. A metal shell is placed in the acetabulum and a stem with a replacement femoral head is inserted into the femur. Exercises after surgery are important for restoring hip mobility and strength. Complications can include blood clots, infection, and dislocation but improvements in technique and technology have increased the effectiveness of hip replacements.
New developments in shoulder arthroscopy
This document discusses new developments in arthroscopic shoulder surgery. It describes various shoulder pathologies that can be addressed with arthroscopic surgery, including painful conditions like rotator cuff tears, biceps tendinosis, and frozen shoulder. It also discusses unstable shoulder conditions like anterior glenohumeral instability. The document provides details on surgical techniques for treating various partial and full-thickness rotator cuff tears arthroscopically. It also describes options for managing massive, contracted rotator cuff tears as well as glenohumeral instability with significant bone loss, such as the arthroscopic Latarjet procedure.
Hip Resurfacing
This document summarizes the history and process of hip resurfacing surgery. It discusses how hip resurfacing procedures aim to mimic the natural hip joint using 2-3 components: an acetabular component and bearing surface, and a femoral component. The document then outlines the design process for the femoral component, including reconstructing the proximal femur through sketches, sweeps, and blend operations in CAD software. Finite element analysis is conducted to test the implant design and ensure stress levels are below yield strengths when subjected to loads up to 2-3 times body weight. The conclusion is that the implant design has low chances of failure based on the FEA results.
Shoulder arthroplasty & Physiotherapy
Dr. Satyendra Bhattacharyya's document discusses the history and procedure of shoulder arthroplasty. It begins with the first documented shoulder replacement in 1894, but focuses on developments starting in 1951 by Dr. Charles Neer, who created the first hemi-arthroplasty and total shoulder replacement. The document then discusses factors that influence arthroplasty outcomes, indications for the procedure for conditions like osteoarthritis and rheumatoid arthritis, and details each step of the surgical procedure. It concludes by describing postoperative rehabilitation protocols.
Hemiarthroplasty
This document provides an overview of hemiarthroplasty, which involves replacing the femoral head with a prosthesis while retaining the natural acetabulum. It discusses the history and types of prostheses used in hemiarthroplasty. The indications, surgical procedure, postoperative care, and possible complications of hemiarthroplasty are described. A case example of a 78-year-old female undergoing cemented bipolar hemiarthroplasty for a fractured neck of femur is presented.
Stealth knee brace brochure
The document describes a knee brace called the Stealth ZVSTM Custom Air Elite Knee Brace. It has several patented features including a suspension pump system that prevents slippage, a total anatomical hinge that guides knee movement naturally, and a rotational control system that stabilizes rotational instability. The brace is custom made through fiberglass molding to ensure a perfect fit for each individual. It is designed to control forces on the knee and reduce stresses from high impacts or prolonged activity.
Gender Specific High Flex Knee replacement
Since 60 percent of patients ungergoing a knee replacement are women, it makes sense to have a specially designed implant for the female anatomy. The Gender specific knee implant is an unique prosthesis designed for women's anatomy. Women with bilateral knee replacements one with a tradiitonal knee and the other with a gender knee state that they are more comfortable with the gender knee.
H1302034856
This document presents a study analyzing stress levels in various materials used in total knee replacements under static conditions. A 3D model of a knee prosthesis was created in SolidWorks. Finite element analysis was then performed in ABAQUS to calculate stress, contact pressure, and deformation in different biomaterials. The materials analyzed for the femoral component included 316L stainless steel, cobalt-chromium alloy, titanium alloy, porous tantalum, and zirconia. Ultra-high molecular weight polyethylene was used for the tibial component. An analytic hierarchy process was used to determine the best femoral material considering factors like stress levels, strain, density, and osseointegration. The results indicated titanium alloy experienced the highest stress and strain
hemiarthroplastyanshulfinal-200726074139.pptx
A 78-year-old female presented with left hip pain and swelling after a fall. X-rays showed a left femoral neck fracture. She underwent a cemented bipolar hemiarthroplasty of the left hip using a modified Hardinge approach. This involved removing the femoral head and replacing it with a prosthesis while retaining the natural acetabulum. Post-operatively, x-rays confirmed appropriate placement of the prosthesis.
Osteoarthritis
The document discusses considerations for correcting varus deformity during total knee arthroplasty for osteoarthritis. It analyzed 20 patients with over 15 degrees of varus deformity who underwent TKA. The goal of TKA is to restore the mechanical axis of the knee to distribute load evenly and reduce wear. This involves correcting alignment through distal femoral and proximal tibial cuts while balancing the extension and flexion gaps. Restoring proper alignment through the joint line and balancing the soft tissues is important for implant longevity and stability.
Extremity_Wear_Testing_-_Total_Ankle_and_Shoulder_Replacement_Testing_
This document discusses testing methods for total ankle and shoulder replacement implants. It notes that while testing methods are standardized for knee and hip implants, extremity implants like ankle and shoulder prosthetics have not been as extensively tested. The document outlines current testing procedures for these implants, which typically use modified knee or hip simulators. It discusses adapting simulators to test total ankle replacements, including setting up fixtures and inputting motion profiles. Testing procedures for total shoulder replacements are also described, such as using a hip simulator with custom fixtures to simulate shoulder motion. The document stresses the need for more research on in vivo joint motions and forces to further improve testing methods for these implants.
