Bony root injuries to meniscus

 

SUSTAINED ACL WITH ? PCL AND LCL INJURY

 EUA REVELAED ONLY ACL, PCL Grade 1 WITH INTACT ACL

 MRI REVEALED POSSIBLE ROOT AVULSION LATERAL  MENISCUS MORE THAN MEDIAL. SCOPY REVEALED LATERAL MENISCAL ROOT WHICH WAS UNSTABLE HENCE A SCREW AND ROOT SUTURES THRU AN ABS BUTTON WAS DONE

lllr larger root g\fragmnt with PCL fixed with 2 screws and percutaneous scope assisted mcl repair

aseptic loosening hip

 47 year old female 6 years post primary thr with progressive pain. The acetabular cup appears to beloose and migrated  superior- laterally with significant posterior column bone loss. got away with a jumbocup and autologous grafting. host bone contact was just 60 percent. the below in a 11 post op rev pics 

dejour type 2 trochles with patellofemoral instabilty

Presented with pain and swelling lt knee. rt knee had a patelelofemoral mpfl reconstruction 10 months ago. no major complaints, although apprehension is positive, post trochleoplasty and MPFL reconstruction pics are below

Trochlear bump ie: ski jump has be removed the trochlear groove lateraised correcting the TT/TG distance , trochleoplasty and mpfl  reconstruction done

Tkr in Arthritic knee with tibial fracture

51

51 year old Pt 10 years post patellectomy presented with fracture  Tibia. Patellectomy was  for infection post fixation for a fracture patella> scar had healed by secondary intention

After couselling the patient we did fixation and Tkr with a stemmed Tina and mobilesed non wt bearing for six weeks

Achieved ROM 10 to 80 degrees with and extensor lag of 10 degrees at 2 months

She was glad to get back to work at 2 months

The option of 2 stage was advised elsewhere is acceptable but the time between 2 stages and overall rehab may be close to 6 months

  

MOM lt hip with rising cobalt Levels

71  yr old patient 12 yrs after lt THR  with rising cobalt levels  of one year duration with no local symptoms. Netflix movie "Bleeding heart"  convinced the patient of revision inspite of lack of symptoms.  All other blood parameters. Bone scan and MARS MRI done in 1.5 T machine was normal.

 There was local metallosis or infection.  manage d to retain a well fixed sleeve and changed the cup to 56 from 54 and a lateralised 4+4 Calcar replacement stem with ceramic on poly THR was done

 This was my revision of Srom in 3 cases where in I could retain the sleeve and patient walked like a primary hip.

 the rt side has a COC revision hip done after the MOM fiasco

inter prosthetic fracture in a 67 year rheumatoid pt

 The fracture was non healing for 3 months of conservative care elsewhere

To maintain her mobility the options of fixation and femoral replacement was considered as the hip was painful too due to the migration . A THR  link total femur was linked to the previous RHK tibia which was asymptotic

 

superior capsular reconstruction

rt handed 60 year old lady with 4 cm retraction gautlier grade 3

post op 3 months thanks to physio Sreejith's efforts post op

painful dislocated rt shoulder in a 76 year old lady

Mri showed chronic cuff tear grade 3 gautilier

 with subscap tear 

 The issue  of  reverse shoulder was easy as she has pain and was unstable due to cuff tear arthropathy with thrice weekly dislocation during sleep. Before the arrival of Grammonts prosthesis,  fusion could have been the only option

superior capsular reconstruction  have come recently from Dr. Mihata, however as there is already cuff arthropathy, pain at rest may not relieved.  Capsular reconstruction would improve movement but not increase strength and in this case the instability sealed  the solution.

The next problem whether a constrained liner was needed  or a subscap repair was mandatory or desirable. In this case as subs cap was retracted  further to try repair a constrained liner was use  and the result  is below

6 year post hybrid technique in rt periprosthetic fracture femur

The rt hip under went distal cementing and proximal uncemented in a 80 year old lady who presented 6 years later with no local issues in the hip. This was considered a quick operation for an elderly peri prosthetic fracture for early mobilisation with an uncememeted hip. the porocoat distally was removed to reduce the stem cement bonding.Happy to see no major lysis or sinkage 6 years down the line

posterior dislocation 2 year post posterior stabilised knee

This happenned while she was getting up from a foot stool like devise ( possible high flexion). felt a clunk and could not walk. presented with an FFD of 30 with no further flexion or extension with xray below showing subluxed knee.
 Under GA  it reduced in full flexion and anterior force ie anterior draw and was stable with no further instabilty or laxity, no clinical laxity in any range.  This was the first time I saw this and hope fully the last time. so watch out high flexion guys who show videos of squats and more ? She is 6 months post reduction with no further issues yet

meniscal repalcement

26 yr old male with 2 year post acl tear medial meniscal  was in bits except an intact  root and  a peripheral rim was intactInspite of ACL a reconstruction the evidence of impending osteoarthritis  made us consider a meniscal replacement when  transplant was unavailable.  He is two year post op with no symptoms to date recent mri shows still some tissue perisisting although smaller than immediate postop

nail plate devise

An out line on the design and rationale of the nail plate device for stabilising a periprosthetic fracture of distal femur in total knee replacement-       Dr. Jacob Varughese

 Displaced supracondylar fractures (type 2) needs to be properly aligned and stabilized for an optimal outcome. Stabilization using intramedullary nails, locking plates, external fixators have been described.  The small porotic distal fragment precludes stable fixation with either plate or nail  to commence immediate mobilisation. 

Design of a nail plate  device

In 2009 following difficulty in stabilising these distal femoral fractures  combination of a separate  Intra medullary nail  and a locking  plate  was used to stabilise and mobilise the elderly  above mentioned osteoporotic fracture. This was  repeated in  bilateral case where in the nail was removed  to pass the distal locking screws  from the plate resulting in translation of the distal fragment ref  pic 4  below.  Both the fractures healed in 3 months and the patient was mobilised weigth bearing

Procedure

Knee replacement incision.

A supracondylar nail 9 mm in diameter was passed through the distal fragment  and using this to reduce the fragment and pass it retrograde into the proximal fragment. This avoids soft tissue stripping and quick reduction of the fracture in anterior-posterior and medial lateral planes  with out soft tissue stripping associated with reduction with a plate device. This nail devise could be locked proximally and distally if possible or at this stage a locking plate is passed through a MIPPO technique on the lateral side and locking screws can be applied distally though the incision and percutaneous screws can be applied proximally. In the case  in picture 3 on the right knee the nail was removed after the plate was applied distally to facilitate  screw insertion resulting in translation in the medio-lateral plane. Therefore it was decided to use both nail and plate in 3 further cases where in we obtained stable reduction to facilitate immediate mobilisation.

 With these results we attempted to design a new implant ( nail plate device) to improve the technique and rigidity of  fixation

hybrid technique in periprosthetic femoral fractures

This patient had cementing of the distal half of the uncemented porocoat stem with wiring around the proximal uncemented part  for a periprosthetic fracture 6 years ago
Doing well so far  with no lysis so far
I did expect loosening on the cement bone interface but luckily no lysis so far

 so this is an option in a elderly periprosthetic fracture

Root tears of meniscus

  60 year old lady with sudden onset sharp pain  lt knee. She was previously asymptomatic and very active. clinical exam revealed strong medial meniscal signs  and MRI showed a meniscal extrusion with radial tear adjacent to root.
 she was send for a week of physio and 3 days of NSAID and was reviewed .  she had complete relief and had no meniscal signs and was even able to squat

 After repairing every  root tear  I saw I sometimes think whether I over did the same. Meniscal extrusion remained in at least 3 of the 12 1 repaired in the last 2 years. Pt were definitely asymptomatic.

 To avoid extrusion do we now need to start centralisation sutures like the japs.
Spare a thought guys.
