What Is The Remedy For Knee Injury?

Respected sir
I am a serving army personnel and i have a 11 yr old knee injury which has
destablised my life.The history of injury is as under :-

1.RTA in the year 2000with sustained CLW and minor trauma to the right side
of patella.I had some instability in the knee and it would give way.
2.Orthroscopy was conducted in 2001 at PGIMS,Rohtak in 2001 with possible
debridement(i dont have any papers of either RTA or Orthroscpy in 2001).
3. Joined IMA for Army training in JUL 2003 which involves rigrous and
strenous physical training.Even before i joined my training i had swelling
in my knee and during the training i used to have recurrent swelling in my
knee and had Hemarthrosis (associated with intense pain and inability to
even move the knee) twice in 2003 and blood had to be aspirated thereafter.
4.The same Hemarthrosis happened in Jan 2006 and repeat Orthroscopy was
conducted (no biopsy conucted) in Feb 2006 with diagnosis as under:-
(a). intact ACL/lateral medial meniscus
(b). Early Chondromalacia medial side of patella with lateral femoral
condyle.
(c). Synovial hypertrophy and pigmentation.
5.I get swelling even on trivial trauma or excess walking.Since 2006 i have
stopped running/playing games. Hemarthrosis happened again in sep 2007
; blood aspirated.
6. Heamarthrosis happened 0n 30 Oct 2010 ; blood aspirated twice. I was able
to walk and do my routine activities again. Repeat orthroscopy conducted on
09 Dec 2010(By DR Prateek Gupta at SGRH,Delhi) with debridement.Biopsy
results indicated PVNS (Biopsy reports att as pic 7& 8).The doctors
told that there
is no possible cure for it. Only SYNOVECTOMY (Radioactive/Orthroscopic) is the
possible treatment.
7. Now after 15 weeks of orthroscopy even now there is mild swelling in my
knee.
8. Can u plz suggest me what is future of my knee joint???Bcoz during
Orthroscopy in 2006 the doc told me that my knee will not work for more than
5-10 years.
9. In a span of 10 yrs i three times ORTHOSCOPY has been conducted on my
knee.And the Quadriceps muscles are quite weak of the affected leg
though i am taking Q ex regularly.

Thanks so much in anticipation.
With warm regards.....
