1) PCL avulsion injuries involve the tearing of the PCL from the tibia, often with a bone fragment. Arthroscopic examination is required before surgical repair through a posterior approach to check for other knee injuries.
2) Surgical repair of a PCL avulsion involves exposing the tibial attachment through a medial or posterior approach. The bone fragment is reattached using screws or sutures passed through drill holes. The posterior capsule is also repaired with sutures.
3) Postoperative care following PCL avulsion repair involves the use of a hinged knee brace, touch-down weight bearing, and a physical therapy regimen focusing on range of motion and strengthening exercises.

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.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Pulmonary Thromboembolism - etilogy, types, medical- Surgical and nursing man...VarunMahajani
Disruption of blood supply to lung alveoli due to blockage of one or more pulmonary blood vessels is called as Pulmonary thromboembolism. In this presentation we will discuss its causes, types and its management in depth.
1. PCL Avulsion
CAMPBELL’S OPRATIVE ORTHOPAEDICS 2013
By: Dr Hamid Hejrati
Resident of Orthopedic Surgery
Iran, Mashhad university of medical science
2.
3. If the isolated posterior cruciate ligament disruption
is characterized by avulsion of a large piece of bone
from the posterior aspect of the tibia and a posterior
approach is planned, the knee must be examined
arthroscopically to rule out other orthopaedic
disorders before making the approach. This approach
does not permit exploration of the knee or correction
of any other disorder.
4. REPAIR OF BONY AVULSION OF PCL
If the posterior cruciate ligament is avulsed from the
tibia and the repair is to be done through a medial
approach, dissect the posterior skin and
subcutaneous tissue as a single layer to the
posteromedial corner and, with the knee flexed to 90
degrees, retract the medial head of the
gastrocnemius and the popliteal structures
posteriorly to adequately expose the tibial
attachment of the ligament.
5. In the absence of a major medial compartment
disruption, a posteromedial capsular incision allows
adequate exposure of the tibial attachment. The
most medial portion of an intact posterior horn of
the medial meniscus may make exposure and
placement of the suture in the distal end of the
ligament difficult, but excision of the intact medial
meniscus is not necessary.
6. Fit the fragment of bone carefully into the crater and
secure it with a cancellous screw if the fragment is
large enough or with a nonabsorbable suture passed
through parallel drill holes to the anterior aspect of
the tibia.
Repair the frequently found tear of the posterior
capsule with interrupted sutures.
7.
8. BURKS AND SCHAFFER
With the patient prone, make a gently curved
incision, with a horizontal limb near the flexion crease
of the knee and a vertical limb overlying the medial
aspect of the gastrocnemius muscle.
Carry the dissection to the deep fascial layer and
incise it vertically over the medial head of the
gastrocnemius.
9. Protect the medial sural cutaneous nerve (posterior
cutaneous nerve of the calf), which usually perforates
the deep fascia distal to the horizontal limb of the
incision.
10. Identify the medial border of the medial gastrocnemius
and bluntly develop the interval between it and the
semimembranosus tendon, exposing the posterior joint
capsule. The middle geniculate artery may be
encountered near the midposterior capsule and can be
ligated if necessary. By lateral retraction on the medial
head of the gastrocnemius, no tension is directly applied
to the motor branch to the medial head of the
gastrocnemius, the only motor branch from the tibial
nerve in the popliteal fossa that traverses medially.
11. The thick muscle belly protects the neurovascular
structures as the capsule is exposed. Dissection on
this protected medial side of the popliteal fossa is
therefore relatively safe.
12. Expose the posterior aspect of the proximal tibia and
posterior margins of the femoral condyle.
If further lateral exposure is necessary, release a
portion of the tendinous origin of the medial head of
the gastrocnemius from the distal femur and joint
capsule. Slight knee flexion will aid exposure, and
complete sectioning of the medial head of the
gastrocnemius rarely is needed.
13. Make a vertical incision through the posterior
capsule to expose the contents of the posterior
intercondylar notch and the tibial attachment of the
posterior cruciate ligament.
14. Suture the capsular incision, allow the gastrocnemius
to settle into position, approximate the subcutaneous
layers, and close the skin in a routine fashion.
15.
16. Tibial Avulsion of PCL
The PCl tibial avulsion is approached similarly to
tibial inlay reconstruction.
The patient is positioned supine, to facilitate
arthroscopic examination.
The leg is brought into a figure 4 position, with the
knee flexed to 90 degrees and the bump
repositioned under the lateral ankle.
17. A 6-cm incision is made
over the posterior border
of the tibia from the
crease of the popliteal
fossa and curving distally
along the posteromedial
border of the tibia.
18. The dissection is continued through the
subcutaneous fat to the sartorius fascia and the
fascia overlying the medial head of the
gastrocnemius.
The fascia is incised along the palpable
posteromedial tibial border
19. The semimembranosus and pes anserinus tendons
are retracted anteriorly and proximally.
The medial head of the gastrocnemius is elevated
from the tibial cortex and retracted posteriorly.
20. The medial border of the gastrocnemius is followed
distally along the posterior tibia, and the proximal
border of the popliteus muscle is identified. The
popliteus muscle is elevated subperiosteally off the
posteromedial surface of the tibia and mobilized
laterally and distally.
21. A vertical arthrotomy is made, and the avulsed
fragment of the tibia with the attached PCl is
identified.
The bone fragment and PCl are reduced and secured
with a 4.0-mm cortical or a 6.5-mm cancellous screw
and spiked washer, depending on the size of the
fragment.
The reduction is confirmed with fluoroscopy or a
radiograph.
22.
23. POSTOPERATIVE CARE
A hinged knee brace is applied and locked in
extension. The patient is awakened and taken to the
recovery room, where pain and neurovascular status
are reevaluated.
Patients may be kept overnight for pain
management and to monitor their neurovascular
status.
24. Patients are given instructions for exercises (quadriceps
sets, straight-leg raises, and calf pumps) and crutch
use.
All dressing changes are performed while an anterior
tibial force is applied.
Patients are instructed to maintain touch-down weight
bearing for 1 week.
Partial weight bearing is initiated after the first
postoperative visit.
25. The brace is unlocked after 4 to 6 weeks, and usually
is discontinued after 8 weeks.
Symmetric full hyperextension is achieved, and
passive prone knee flexion, quadriceps sets, and
patellar mobilization exercises are performed with
the assistance of a physical therapist for the first
month.
26. Mini-squats are performed from 0 to 60 degrees
after the first week and from 0 to 90 degrees after
the third week.
Once full, pain-free ROM is achieved, strengthening
is addressed.
The goals for achievement of flexion are 90 degrees
at 4 weeks and 120 degrees at 8 weeks.
